Public Input No. 2012-NFPA 70-2017 [ Global Input ]

ARTICLE 406 Receptacles, Cord Connectors, and Attachment Plugs (Caps), andAttachment Fittings

Statement of Problem and Substantiation for Public Input

The requirements in the article also apply to attachment fittings. The attachment fitting is analogous to the cord connector and the attachment plug (cap). Requirements for attachment fittings were added in the 2017 NEC, § 314.27E, 422.118 and 422.33. Since there’s a title change to Article 406, a “global” input was created for the convenience of CMP 18 (so the entire article that wasn't changed isn’t part of the PI).

Revise the title of 406.7 to read "Attachment Plugs, Attachment Fittings, CordConnectors, and Flanged Surface Devices."


This modification is necessary to correlate with the new text in 2017 NEC 314.27(E) and 422.18 and assists in clarifying that an attachment fitting is different from an attachment plug. Public Input has also been submitted to revise the Section and add a definition of “attachment fitting”. This proposed change is in concert with and supports the revised definition of “receptacle” in 2017 NEC 100 and the proposed definition of “attachment fitting”. Since there is a proposed title change to the section, a “global” input was created for the convenience of the CMP (so the entire section is not part of a single PI).

Type your content here ...Change "Physical Damage" to "Mechanical Damage"


The term, "Physical damage" is not defined in Article 100, though it is used widely in the NEC. Therefore, in accordance with the Style Manual's Section 2.2.2.1 and Section 3.3.4, it should be interpreted in accordance with the standard dictionary definition rather than an "industry-specific term" or "trade terminology." The standard dictionary definition does not exclude temperature, chemicals, and other potential sources of harm. These are clearly not intended in many of the places where the term.appears, based on the requirements listed in those places for equipment subject to physical damage or severe physical damage. Mechanics is a dictionary term commonly understood to refer to the sort of forces our trade terminology has referred to by the term, "physical," to the extent that the Style Manual, in Section 3.2.55 recommends its use despite the apparent conflict with Section 3.3.4 "Mechanical damage" is used elsewhere in NP standards where the NEC uses "Physical damage."

Type your content here ...Replace "listed and identified" with "listed" in all locations


The use of the words "and identified" following the word "listed" is redundant and adds confusion to the NEC. If the equipment is listed, it is already "identified" based on the definition of "identified" and the informational note that follows that definition. The use of the term "listed and identified" would permit the use of a product that is not listed for the purpose to be used where the local inspection authority had "identified" that the product is suitable for the purpose. It appears to me that everywhere the code uses the term "listed" that the intent is that the product be listed for the purpose.

Remove the phrase “the provisions of” throughout the entire NEC and editorial revise each segment oftext as required.


The phrase is unnecessary and redundant. This global public input seeks to request that each NEC Panel (technical committee) review the articles under their responsibility and remove this phrase and reword the text accordingly. The requirements are already provided in the NEC so it does not make sense to refer to provisions. In many cases the phrase should refer to a section, then state that section in accordance with the NEC Style Manual requirements.

Substantiation Examples:

90.6 Formal Interpretations. To promote uniformity of interpretation and application of the provisions of this Code, formal interpretation procedures have been established and are foundin the NFPA Regulations Governing Committee Projects.

110.3(A)Examination, Identification, Installation, Use, and Listing (Product Certification) of Equipment.(1) Suitability for installation and use in conformity with the provisions of this Code

110.30 General. Conductors and equipment used on circuits over 1000 volts, nominal, shall comply with Part I of this article and with 110.30 through 110.41 , which supplement or modifyPart I. In no case shall the provisions of this part apply to equipment on the supply side of the service point.

110.51 General.

(A)Covered. The provisions of this p Part IV shall apply to the installation and use of high-voltage power distribution and utilization equipment that is portable, mobile, or both, such as substations, trailers, cars, mobile shovels, draglines, hoists, drills, dredges, compressors, pumps, conveyors, underground excavators, and the like.

210.13 Ground-Fault Protection of Equipment. Each branch circuit disconnect rated 1000 A or more and installed on solidly grounded wye electrical systems of more than 150 volts to ground, but not exceeding 600 volts phase-to-phase, shall be provided with ground-fault protection of equipment in accordance with the provisions of 230.95.

Exception No. 1: The provisions of this This section shall not apply to a disconnecting means for a continuous industrial process where a nonorderly shutdown will introduce additional or increased hazards.Exception No. 2: The provisions of this This section shall not apply if ground-fault protection of equipment is provided on the supply side of the branch circuit and on the load side of any transformer supplying the branch circuit.

Section 210.60(B)

(B) Receptacle Placement. In applying the provisions of 210.52(A), the total number of receptacle outlets shall not be less than the minimum number that would comply with theprovisions of that section. These receptacle outlets shall be permitted to be located conveniently for permanent furniture layout. At least two receptacle outlets shall be readily accessible. Where receptacles are installed behind the bed, the receptacle shall be located to prevent the bed from contacting any attachment plug that may be installed or the receptacle shall be provided with a suitable guard.

Each code making panel should set time aside to review the requirements under their purview toensure that new and existing requirements are in compliance with the NEC style manual.


Code making panels are responsible for ensuring that the Code text which agreed upon at the technical panel meetings comply with all requirements of the NEC style manual. It would be prudent for each code making panel to set time aside to review the requirements under their purview to ensure that not only new but existing requirements are in compliance with the requirements of the NEC style manual.

Adherence to the NEC style manual promotes consistency throughout the NEC adding to clarity to the users of the NEC. Code making panels should spend available time reviewing for such important style manual requirements as the following: (These are just some examples and not a comprehensive list of style manual requirements.)

Unenforceable Terms. The NEC shall not contain references or requirements that are unenforceable or vague. The terms contained in Table 3.2.1 of the style manual shall be reviewed in context, and, addressed if the resulting requirement is unenforceable or vague. Examples of unenforceable and Vague Terms include the following:

designed for the purpose.goodadequatefrequent(ly)

Writing in present text. Requirements must be written in present text and not future text. A good example of this is as follows:

Correct: No conductor shall be used in such a manner that its operating temperature exceeds that designated for the type of insulated conductor involved.Incorrect: No conductor shall be used in such a manner that its operating temperature will exceed that designated for the type of insulated conductor involved.

The terms “satisfactory” - "equal" - "equivalent", etc., are examples of numerous subjectiveterms found in the NEC where decisions of suitability fall under the purview of the AHJ.Changing or supplementing these terms to "approved" - "approved equivalent" will continuethe alignment of language used throughout the NEC.

I authored a couple of such changes for the 2014 NEC that were adopted in the 2017. It wassuggested to me by someone from NFPA that I submit a global input, so a committee wouldbe appointed to locate and revise all such subjective terms to include the word "approved".

This will reduce the number of terms used to determine suitability of equipment as it appliesto installation/inspection to one of the following: "Listed" - "Identified" - "Approved"


I think the language in my global proposal not only states the problem, but offers a viable solution to facilitate uniformity of language throughout the NEC.

Public Input No. 3427-NFPA 70-2017 [ Definition: Receptacle Outlet. ]

Receptacle Outlet.

An outlet where one or more receptacles are installed. (CMP-18)

Reliability.

Reliability. The probability that a system or component will operate properly for a specified period of timeunder design operating conditions without failure.

Informational Note: Additional information is available in I EEE 3006.5 Recommended Practice for the Use of Probability Methods for Conducting a Reliability Analysis of Industrial and Commercial Power Systems


We need to recognize that the greater public hazard lies in the absence of electrical rather than fire hazard. In other words, forced outages occur with far greater frequency than fires and needs engineering solutions that the inspection community needs to tool up for. This proposed definition pairs with the proposed definition of "Availability".

Electrical safety has a strong correlation with power system reliability -- for electricians as well as occupants. Reliability is the probability that a product or service will operate properly for a specified period of time under design operating conditions without failure. Reliability is time dependent. The longer the time, the lower the reliability, regardless of what the system design is. The higher quality of the system design, the higher the probability of successful operation for a longer period of time.

By comparison, a related term is Availability. Availability is the long-term average fraction of time that a repairable component or system is in service and satisfactorily performing its intended function. For example, if the electricity is off for one hour in a year, but the rest of the year the electricity is on, the availability of electrical power for that year is 8759 hours divided by 8760 hours, which is 0.999886.

As the mother standard for nearly all electrical power standards in the world these distinctions need to track in the vocabulary of our industry - specifically in Article 100 -- because this is the go-to place for electrical terminology in global electrical standards. The word "reliability" appears 10 times in the 2017 NEC

The reliability of a power system is its essential characteristic. Everything we do in the power industry is focused on making sure that power is present and safe. This definition, coupled with the tern "available" should track explicitly in the NEC and should raise awareness that reliability calculations are as essential as short circuit and load flow calculations.

Informational Note to the term Receptacle

A duplex receptacle is an example of a multiple receptacle that has two receptacles on the sameyoke.


There are important rules in the NEC that address the application of multiple receptacles on a circuit, such as 210.21(B)(3), which permits two or more 15A receptacles on a 20A circuit. In over 40 years of training, I have found many that feel a duplex receptacle is not two receptacles, and they misapply this requirement. Let’s make it crystal clear that a duplex receptacle is two receptacles.

Public Input No. 1435-NFPA 70-2017 [ Definition: Receptacle. ]

Receptacle.

A contact device installed at the outlet for the connection of an attachment plug, or for the directconnection of electrical utilization equipment designed to mate with the corresponding contactdevice. A single receptacle is a single contact device with no other contact device on the sameyoke. A multiple receptacle is two or more contact devices on the same yoke. (CMP-18)


As currently written, the definition states that a duplex receptacle is one receptacle, because the language is singular instead of plural (if the word "is" was "are" and "receptacle" was plural it could be a different story). The rules for receptacles and their circuit requirements are quite different when it comes to single receptacles and multiple receptacles, so this change to this definition is warranted. Reading 220.14(I) seems to support this position as well.

Receptacle.

A A singlereceptacle is a single contact device with no other contact device on the same yoke. A multiple receptacle istwo yoke is a single receptcle. Two or more contact devices on the same yoke. yoke are multiplereceptacles (CMP-18)


There continues to be much confusion and debate among electricians and inspectors as to whether a typical duplex receptacle is actually 2 receptacles or just 1 receptacle. Present wording seems to be creating 2 sub categories of definitions-a "single receptacle" and "multiple receptacle". There are only 2 other code sections that use the term "multiple receptacle". Those sections are 220.14(I) and 406.3(E). Does this mean that these are the only code rules that apply to a duplex receptacle? I certainly don't think that is the intent. An electronic search of the code reveals the following. The term "duplex receptacle" is used at least 8 times in the code? But what is a "duplex receptacle"? There is no definition in the code for it. References to "quadruplex receptacles" are used 3 times in the code. What is a "quadruplex receptacle". There is no definition in the code for it. The term "single receptacle" is used 13 times. What about a "triplex receptacle"? This term is not used at all in the code, but these types of devices exist. Are there no code rules for them? This revision is necessary to make it clear that 2 contact devices on the same yoke are considered 2 receptacles. 3 contact devices on the same yoke are 3 receptacles and 4 contact devices on the same yoke are 4 receptacles. The second sentence of Section 220.14(I) supports this by stating..."A single piece of equipment consisting of a multiple receptacle comprised of four or more receptacles shall be calculated at not less than 90 volt-amperes per receptacle", which should calculate to be 360 volt-amps. Other rules such as 210.21(B)(1), 210.21(B)(2) and 210.21(B)(3), as well as 210.23 and 210.24 will become much easier to understand with the revisions I am proposing.

Receptacle.

A single receptacle is a single contact device with no other contact device on the sameyoke. A multiple receptacle is two or more contact devices on the same yoke. (CMP-18)


Delete text added to this definition in the 2017 NEC, because it created confusion when the term receptacle is used throughout the Code. For example, the NEC requires a lighting outlet in some applications; what happens when this product (receptacle) is installed in a lighting outlet? Does this now make a lighting outlet a receptacle outlet! Another example is if you install this ‘receptacle’ in a lighting outlet in an outdoor location, does this ‘receptacle’ now need to be GFCI protected (per 210.8)?By deleting the text we go back to what we always knew a receptacle was, and as a bonus all of the rules in the NEC related to receptacles work!

This public input is submitted on behalf of task group appointed by the NEC Correlating Committee. This task group was appointed to identify potential issues in the NEC with respect to how definitions in both Article 100 and the XXX.2


1 of 3 10/4/2017, 1:16 PM

sections of this Code apply. The member of the task group are: David Hittinger, Rich Holub, Chris Hunter, Dave Williams, Chris Porter, Alan Manche, Ken Boyce, John Kovacik, Donny Cook, Dave Kendall and Jim Dollard.

Section 2.2.2.1 of the NEC Style Manual requires that in general definitions that appear in two or more articles be located in Article 100. Section 2.2.2.2 requires that where an individual article contains definition(s), they be located in the second section (XXX.2) of the article. It is extremely important to note that the style manual does not prohibit a definition in the second section of an article from applying elsewhere in the NEC. The style manual clearly states that in general definitions that appear in two or more articles shall be located in Article 100. This has confused many code users in the past. This style manual requirement is accurate and these public inputs are simply an attempt to provide needed clarity. See the example below:

344.2 Definition.Rigid Metal Conduit (RMC). A threadable raceway of circular cross section designed for the physical protection and routing of conductors and cables and for use as an equipment grounding conductor when installed with its integral or associated coupling and appropriate fittings.

The definition of the term “rigid metal conduit” is appropriately located in the article that contains general, installation and construction specifications for this raceway. It is commonly understood that the term “rigid metal conduit” is used in more than one article. There are many articles that contain a single definition that is necessary for application of the contained requirements but will apply elsewhere in the NEC. This occurs in articles that address cable assemblies, raceways, systems and more.This public input seeks to delete the last sentence in the first paragraph, as it is unnecessary. A new sentence is proposed to simply inform the user of the code that definitions are also found in the second section (XXX.2) of other articles.This public input is supplemented with proposed revisions to the second section (XXX.2) of articles that contain definitions. New parent text is proposed for these sections to increase clarity and usability. There are two different scenarios that will be addressed. First, any second section (XXX.2) that contains definitions that apply only within that article will contain parent text as follows:

XXX.2 Definitions. The definitions in this section shall apply only within this article.

Second, any second section (XXX.2) that contains definitions that apply within the individual article and throughout the code will contain parent text as follows:

XXX.2 Definitions. The definitions in this section shall apply within this article and throughout the code.

In a few cases, in the second section (XXX.2) of an Article there are definitions that will apply only in that Article and some that will apply in that Article and throughout the code. New parent text and first level subdivisions are proposed to achieve clarity and usability The combination of these proposed revisions will provide necessary clarity and usability with respect to application of definitions. These actions will also achieve compliance with the NEC Style Manual.

Isolated ground receptacles installed in nonmetallic boxes shall be covered with a nonmetallic faceplate.

Exception: Where an isolated ground receptacle is installed in a nonmetallic box, a metal faceplate shall bepermitted if the box contains a feature or accessory that permits the effective grounding of the faceplate.


Grounding and bonding still continues to be one of the most misunderstood and misapplied sections of the NEC. Most of the problems can be traced back to using undefined terminology (trade slang in many cases) or incorrect terminology. The term “grounding conductor” is one that is no longer defined. As part of a Correlating Committee Task Force activity on grounding and bonding in general, this term and its related definition was removed from the NEC during the 2008 NEC cycle. The term had been found to be misapplied in a number of instances and the definition of “grounding conductor” was determined to be very close to the definition of “grounding electrode conductor” yet, many uses of the term in previous editions of the NEC were found to be more correctly to be either “equipment grounding conductor”, “grounding electrode conductor” or one of the several types of “bonding jumper”.

The revised text uses terms defined in the Code and is consistent with the context of the meaning of the section where the revisions are made. The revisions are made to provide clarity, and consistency in terminology usage.

It is requested the Correlating Committee consider a policy or procedures that require a review when a term under the responsibility of a specific Code panel is used by another Code panel. The panel responsible for the term is to review the application to ensure correct usage. It is further requested that when new terms are created that would be identified as under the responsibility of another Code panel that the new term and application be reviewed by the Code panel that would have responsibility for use and application.

Public Input No. 1319-NFPA 70-2017 [ Section No. 406.3(D)(2) ]


Isolated ground receptacles installed in nonmetallic boxes shall be covered with a nonmetallic faceplate.

Exception No.1 : Where an isolated ground receptacle is installed in a nonmetallic box, a metal faceplate shallbe permitted if the box contains a feature or accessory that permits the effective grounding of the faceplate.

Exception No.2: Metal faceplates shall be permitted to be installed where the branch circuit supplying thereceptacle outlet is provided with ground-fault circuit interrupter protection.


This present rule leaves installing non-metallic plates as the only option if the box has no way to ground the plate. What if a customer or installer wants to install some stainless steel brass receptacle plates? The circuit would need to be rewired or the plastic box ripped out and replaced with a metal box just for the metal plates! Providing a GFCI breaker for the branch circuit is a good, safe alternative to completely rewiring the circuit or ripping out and replacing the box. This proposed exception follows the same logic as some other similar rules where there is no equipment ground wire, such as 406.4(D)(2)(b)+(c) and also section 404.9(B) exception 1, and section 410.44 exception 3 and newly proposed 406.6(B) exception. One important note I want to make here, I am purposefully requiring the branch circuit to be provided with GFCI protection, since installing an ungrounded/unbonded metal plate on a GFCI type of receptacle could still allow the metal plate to become dangerously energized with no GFCI protection, if the ungrounded wire feeding the receptacle were to come in contact with the metal pate. Providing the GFCI protection at the beginning of the circuit, makes for a much safer option and virtually eliminates that scenario from happening since the entire circuit would have GFCI protection. It also provides a safe alternative and some needed relief for installers and customers who presently have very few options.

I am fully in favor of ground-fault protection for personnel. However, the huge expansion of GFCI requirements in Section 210.8(B) for receptacles up to 50-amperes single phase, and 100-amperes three phase was not well justified. The limit of up to 20-amperes and 120-volts for single phase circuits not only covers single family dwellings, and a plethora of commercial occupancies, as well as construction sites, and more, which is the largest percentage of installations out there, and CMP 2 and CMP 18 members can feel good about the reasonable and justified requirement that they have in place already. If a special location in NEC Chapter 5 really warrants extra protection, via a GFCI, and sufficient justification has been provided, then the appropriate Code Making Panel can address the issue. Our electrical manufacturers do a great job, and are a very important and valued part of our electrical industry. CMP 18 is thoughtful, and wants to do the right thing. Additional requirements in the NEC must be looked at holistically, over all persons and industries affected by the change. What is good for an electrical manufacturer may not be good for individuals or businesses where costs and regulations seem to continually increase.

1 of 3 10/4/2017, 1:23 PM

















I have proposed a change in section 406 because after trying a few years ago to work with a NEMA representative regarding the un-safe stab-in receptacle feature, he had no time to communicate my message and stated to just place a proposal. I would love to see the manufacturer stop creating the stab-in feature in receptacles, but I have no way to communicate with them. I thought a good place to start would be in replacements only, until they get the word and stop making them. Every Training Class I have provided in the last 20years has noted that they love the extra money Contractors can make by performing service calls on burnt 15amp devices, usually in Apt complexes. I am on my way to an Inspection now, where the same condition existed, which sent our fire trucks to the home. I know the stats would be impossible to provide, because it is too detailed a subject for Inspectors to keep track of and Fire Marshalls to understand.

Where attachment to an equipment grounding conductor does not exist in the receptacle enclosure, theinstallation shall comply with (D) ? (2) ? (a), (D)(2)(b), or (D)(2)(c).


(b) A non–grounding-type receptacle(s) shall be permitted to be replaced with a ground-fault circuitinterrupter-type of receptacle(s). These receptacles

or their cover plates

shall be marked “No Equipment Ground.” An equipment grounding bonding conductor shall not be connectedfrom the ground-fault circuit-interrupter-type receptacle to any outlet supplied from the ground-fault circuit-interrupter receptacle.

(c) A non–grounding-type receptacle(s) shall be permitted to be replaced with a grounding-typereceptacle(s) where supplied through a ground-fault circuit interrupter.

Where grounding-type receptacles are

supplied through the ground-fault circuit interrupter,

grounding-type receptacles or their cover plates

shall be marked “GFCI Protected” and “No Equipment

Ground,” visible after installation

. An equipment grounding equipment bonding conductor shall not be connected between the grounding-typereceptacles.




When you want to replace a non-grounding-type of receptacle but the wiring method does NOT include an equipment grounding conductor, such as older 14/2 NM cable with no ground wire, one option is to replace the receptacle with another non-grounding-type of receptacle as permitted in section 406.4(D)(2)(a). However many customers would prefer to have a 3-pronged grounding-type of receptacle instead of the two-prong type. In this case you have two other options. Section 406.4(D)(2)(b) permits a non–grounding-type receptacle to be replaced with a GFCI-type of receptacle. The receptacle or the cover plate must then be marked “No Equipment Ground.” Short of rewiring the circuit, this is a nice compromise and makes good sense to me. The last sentence of that section states “An equipment grounding conductor shall not be connected from the GFCI type receptacle to any outlet supplied from the GFCI receptacle.” Let’s talk about this last sentence for a moment. Does it make any sense to you? Aren't we supposed to connect equipment ground wires to grounding type receptacles? Remember the wiring method supplying power to the receptacle is a 2-wire NM cable with no equipment ground wire. What could this last sentence of the code section be referring to then? Well, I believe it is referring to a wire that would TYPICALLY be used for equipment grounding such as the bare wire in a newer 14/2 NM cable with ground where it was installed from the receptacle to supply other existing outlets on the branch circuit. In this case however, the bare wire inside the NM cable literally does not meet the definition of an equipment grounding conductor in article 100 since it does not provide a path for fault current and has no connection to earth or the grounded conductor. Yet, I believe the intent of the wording should be applied to that bare wire in the cable. If this bare wire were to come in contact with the energized “hot” conductor, it could energize all the metal parts of boxes, light fixtures and any other non-current carrying metal parts connected to this wire. The GFCI


1 of 2 10/4/2017, 1:24 PM

would not provide protection if the bare wire was accidentally touching the line side terminals of the GFCI receptacle! This same logic should also be applied to the last sentence in 406.4(D)(2)(c) when non-grounding –type receptacles are replaced with grounding-type receptacles that are supplied through a GFCI device. Major code revisions for equipment grounding requirements of branch circuits and receptacles were made during the 1960’s, so installers are most likely to encounter these situations in homes wired during and prior to this era. This revision is effort to try and use the correct terminology for a conductor that may perform the function of an "equipment bonding", but does not meet the definition of "equipment grounding conductor".

NOTE: This public input originates from Tentative Interim Amendment No. 17-6 (Log 1266) issued by the Standards Council on August 17, 2017 and per the NFPA Regs., needs to be reconsidered by the Technical Committee for the next edition of the Document.

Substantiation: Exception No. 2 to 406.4(D)(4) was new in the 2017 NEC. In the 2017 NECthe text regarding branch circuit extensions was relocated from 210.12(B) to 210.12(D) andformer Exception No. 2 to 210.12(B) is now located as Exception No. 2 to 210.12(D).Therefore, the reference to Exception No. 210.12(B) in 406.4(D)(4) Exception No. 2 is incorrectand is causing confusion amongst readers of the 2017 National Electrical Code.

Emergency Nature: The standard contains an error or an omission that was overlooked duringthe regular revision process.Because of the relocation of the former Exception No. 2 to 210.12(B) to 201.12(D) there are noexceptions in 210.12(B). Therefore, having the incorrect reference is causing confusion amongstreaders of the National Electrical Code. As the Chair of CMP2, I have received severaltelephone and email inquiries as to the incorrect reference and can substantiate the confusionamongst readers of the 2017 National Electrical Code.

2017 Edition

Reference: 406.4(D)(4), Exception No. 2 TIA 17-6 (SC 17-8-19 / TIA Log #1266) Pursuant to Section 5 of the NFPA Regulations Governing the Development of NFPA Standards, the National Fire Protection Association has issued the following Tentative Interim Amendment to NFPA 70®, National Electrical Code®, 2017 edition. The TIA was processed by the National Electrical Code Panel 18 and the NEC Correlating Committee, and was issued by the Standards Council on August 15, 2017, with an effective date of September 4, 2017. A Tentative Interim Amendment is tentative because it has not been processed through the entire standards-making procedures. It is interim because it is effective only between editions of the standard. A TIA automatically becomes a public input of the proponent for the next edition of the standard; as such, it then is subject to all of the procedures of the standards-making process. 1.

Exception: Locking support and mounting receptacles shall not be required to be tamper-resistant.


Locking support and mounting receptacles are of a different configuration and do not have holes that objects could be inserted into and energized. Most of the time the receptacle will be covered by the utilization equipment, canopy or cover. When the utilization device is not in place, the existing faceplate is combined with the faceplate centerpiece creating a coverplate. Also, the devices are typically on the ceiling or high on the wall.

Once connected the utilization equipment may be considered similar to a hard-connected piece of equipment, as the equipment is locked in place. The installed equipment may be considered as a semi-permanent installation and as such should be treated similar to a permanent installation. Locking support and mounting receptacles are generally protected by location, height or coverage.

The changes are suggested to recognize the difference between a receptacle and an attachment plug, and a locking support and mounting receptacle and a compatible attachment fitting.

Public Input No. 229-NFPA 70-2017 [ New Section after 406.4(D)(6) ]

(7) Controlled Receptacle Removal.

Where removal or replacement of any installed automatic control device or any installed nonlocking-type, 125-volt, 15- or 20-ampere receptacle that incorporates control features to remove power from receptacles thenresults in an absence of those control features on that branch circuit for the purpose of energy management orbuilding automation, remaining installed nonlocking-type, 125-volt, 15- or 20-ampere receptacles marked asspecified in 406.3(E) shall be replaced with uncontrolled receptacles as specified in 406.4(D)(1) and, whererequired, as specified in 406.4(D)(3) - 406.4(D)(6). None of the installed uncontrolled receptacles nor theirfaceplates (cover plates) shall remain marked as specified in 406.3(E).


Where removal or replacement of the automatic control device or of the controlled receptacle results in a loss of energy-management control "downstream" on that same branch circuit over "dumb" receptacles marked as STILL being controlled BUT NOT in actuality, unsafe servicing and maintenance conditions can result.

If CMP-18 deems it necessary, an additional Exception COULD be added for TEMPORARY removal for SERVICING of the automatic control device or of the controlled receptacle, with DATED tags (or the like) affixed adjacent to EACH of the remaining formerly-controlled "dumb" receptacles to indicate the loss of control and with the enforceable date by which energy-management control WILL be restored.

The replacement of faceplates (cover plates) so marked is to address the allowance prior to the 2017 NEC® wherein marked "receptacle outlets" effectively permitted such controlled-receptacle marking to appear instead on the faceplates (cover plates).

(C) Receptacles Mounted on Covers.

Receptacles mounted to and supported by a cover shall be held rigidly against the cover by morethan one screw or , fastener, or other suitable and secure method of attachment, or shall be adevice assembly or box cover listed and identified for securing by a single screw, fastener, or othermethod of attachment .


The existing language of Section 406.5(C) is potentially ambiguous. On its face, "by more than one screw" means the same thing as "by multiple screws." However, this section has been interpreted in the field to mean "by multiple screws" or "by one screw and more (other fasteners)." For instance, the latter interpretation could permit a screw in the center screw hole and rivets through the yoke, but it could also be interpreted to mean any number of other fastening methods.

Personnel in the field should not be required to determine whether "more than one screw" actually means "more than one screw" or "one screw and some other stuff." If the intent of the section is to require secure attachment of a receptacle mounted on a surface-mounted cover by more than just the center screw, the express language of the Code should so provide.

(G) Receptacle Orientation.

Receptacles shall not be installed in a face-up position in or on countertop surfaces or work surfaces unless listed for countertop or worksurface applications.

Receptacles shall not be installed in a face-up position in the area below a sink.


On February 7, 2017 I received the following comment via the contact page on my website, electrical-code-expert.com :

********************************************************************************************************************************************************************************CommentThis morning I was washing dishes at my fiancé's kitchen sink. Water started pouring out. The puddle on the floor was approximately 3'x4'' in a matter of seconds. I turned the water off and started pulling everything that was stored in that cabinet out. I was terrified when I saw an electrical outlet mounted face up in the base of the cabinet. I ran down to the basement and turned off this breakers for everything in the kitchen other than the refrigerator, I think. I'm not sure if I got the on demand water heater mounted under the sink because the breakers are labeled "heater #x" and my fiancé is with his child at MD Anderson C ancer Center. I'm can't to bother him with this. I've searched the Internet to try to determine whether the installation meets code and/or is safe and am not finding a concensus regarding seemingly similar situations. There are no GCFI buttons on the outlet and it is just a plain cover rather than an outdoor water resistant box. The house was built about 2 years ago. I don't trust the GC and don't know the electrician. Can you please provide me with guidance? Thank you!

**********************************************************************************************************************************************************************************

This lady was scared out of her mind because there was a leak in the pipes that connect to the sink. In the cabinet below, someone had installed a receptacle in the "face-up" position. It is not uncommon that pipes connecting to a sink (supply and drain) may somehow spring a leak. In fact, I would say it is quite common. It would make sense that a receptacle outlet installed in the area beneath a sink should NOT be installed in a face-up position. Water can get into that outlet. Circuit breakers do not always trip. Adding this new language could mitigate a potential hazard. The proposed language would also not pose any impact on cost. It's really just common sense, so I hope the CMP will consider adding this language.

(B) Grounding.

Metal faceplates shall be grounded. bonded to an equipment grounding conductor.

Exception: Where no means exists within the recptacle enclosure for connecting to the equipment groundingconductor, or where the wiring method does not include or provide an equipment grounding conuctor, metalfaceplates shall be permitted to be installed without being bonded to the equipment grounding conductor,where the branch circuit supplying the receptacle outlet is provided with ground-fault circuit interrupterprotection.


For the general rule, revising "shall be grounded" was needed since that wording is too vague and could literally permit a metal faceplate to be connected to driven ground rod with no connection to an equipment ground wire and be considered code compliant. It would literally be "grounded" by definition. This revision will clarify the intent, and will provide an effective ground-fault current path for the plate. The exception is needed to provide some relief to installers who work in older buildings that may have wiring methods which don't include an equipment ground wire, such as some older NM cables and knob-and-tube wiring. How can the metal plate be "grounded" if there is no equipment ground wire? This present rule leaves installing non-metallic plates as the only option. What if a customer or installer wants to install some beautiful antique brass receptacle plates? The circuit would need to be rewired just for the metal plates! Providing a GFCI breaker for the branch circuit is a good, safe alternative to completely rewiring the circuit. This exception follows the same logic as some other similar rules where there is no equipment ground wire, such as 406.4(D)(2)(b)+(c) and also section 404.9(B) exception 1, and section 410.44 exception 3. One important note I want to make here, I am purposefully requiring the branch circuit to be provided with GFCI protection, since installing an ungrounded/unbonded metal plate on a GFCI type of receptacle could still allow the metal plate to become dangerously energized with no GFCI protection, if the ungrounded wire feeding the receptacle were to come in contact with the metal pate. Providing the GFCI protection at the beginning of the circuit, makes for a much safer option and virtually eliminates that scenario from happening since the entire circuit would have GFCI protection. It also provides a safe alternative and some needed relief for installers and customers who presently have very few options.

406.7 Attachment Plugs, Cord Connectors, and Flanged Surface Devices, and Attachment Fittings .

All attachment plugs, attachment fittings, cord connectors, and flanged surface devices (inlets and outlets)shall be listed and marked with the manufacturer’s name or identification and voltage and ampere ratings.

Informational Note: Attachment fittings are components and are part of a listed kit or listed utilizationequipment.

(A) Construction of Attachment Plugs and Cord Connectors.

Attachment plugs and cord connectors shall be constructed so that there are no exposed current-carrying partsexcept the prongs, blades, or pins. The cover for wire terminations shall be a part that is essential for theoperation of an attachment plug or connector (dead-front construction).

(B) Connection of Attachment Plugs.

Attachment plugs shall be installed so that their prongs, blades, or pins are not energized unless inserted intoan energized receptacle or cord connectors. No receptacle shall be installed so as to require the insertion of anenergized attachment plug as its source of supply.

(C) Attachment Plug Ejector Mechanisms.

Attachment plug ejector mechanisms shall not adversely affect engagement of the blades of the attachmentplug with the contacts of the receptacle.

(D) Flanged Surface Inlet.

A flanged surface inlet shall be installed such that the prongs, blades, or pins are not energized unless anenergized cord connector is inserted into it.


The purpose is to ensure attachment fittings have appropriate markings, just as required with attachment plugs, cord connectors and flanged surface devices. The modification is necessary to correlate with the new text in 2017 NEC 314.27(E) and 422.18 and assists in clarifying what an attachment fitting is and how it is different from a cord connector or attachment plug. Public Input has also been submitted to add a definition of “attachment fitting”. This proposed change is in concert with and supports the revised definition of “receptacle” in 2017 NEC 100 and the proposed definition of “attachment fitting”.

406.8 Noninterchangeability.

(A) Different voltage or current ratings. Receptacles, cord connectors, and attachment plugs shall beconstructed such that receptacle or cord connectors do not accept an attachment plug with a different voltageor current rating from that for which the device is intended. However, a 20-ampere T-slot receptacle or cordconnector shall be permitted to accept a 15-ampere attachment plug of the same voltage rating.

(B) Non–grounding–type receptacles and connectors. Non–grounding-type receptacles and connectorsshall not accept grounding-type attachment plugs. However, 15-ampere, 125-volt, non–grounding-typenonlocking-type duplex receptacles shall be capable of bonding to the receptacle's cover-plate-mounting screwat least one listed grounding adapter permitting acceptance of 15-ampere, 125-volt, grounding-typenonlocking-type attachment plugs.

In occupancies with existing nongrounding NEMA 1-15R receptacles, listed 3-to-2 grounding adapters minimize users from removing the grounding pin of NEMA 5-15P attachment or molded-on plugs to be able to power appliances via a grounding tab marked to be retained and bonded to the receptacle under the screwhead of cover plate screw. The NEMA Standard WD 6-2016 mandates that the parallel contact openings of the NEMA 1-15R configuration be located CENTRAL to the receptacle face boss and that the distance from the centerline of the parallel contact openings' centerline be located 0.766 from the center of the cover plate screw hole. The screw hole on that grounding tab of listed 3-to-2 grounding adapters is located accordingly for essential alignment.

By contrast, per NEMA Standard WD 6-2016 for NEMA 5-15R receptacles, the centerline of parallel contact openings of the NEMA 5-15R configuration is OFFSET by another 0.125 inch to the center of that receptacle face boss.

In recent times, at least two manufacturers have tried to retool their duplex 1-15R receptacles by utilizing their duplex 5-15R receptacle tooling. Consequently, listed 3-to-2 grounding adapters would not align for mounting and bonding; as a result, users would either completely disregard the instructions to use the adapters' grounding tabs or users would damage the adapters while trying to make them align. The product certifier, upon being notified of this discrepancy, consequently had to delist such dimensionally-noncompliant 15-ampere, 125-volt, non–grounding-type nonlocking-type duplex receptacles. The safety of bonding should not be defeated due to subtle misalignment between products intended to mate together.

See attached photo of a listed 3-to-2 grounding adapter unable to align the hole on the tab to the cover plate screw.

The rule requires "identification", but the allowance discussed "marking." Perhaps I'm using the term "identified" wrong, but as it is defined in article 100 I don't think that I am.

Receptacles of 15 and 20 amperes, 125 and - through 250 volts installed in a wet location shall have anenclosure that is weatherproof whether or not the attachment plug cap is inserted. An outlet box hood installedfor this purpose shall be listed and shall be identified as “extra-duty.” Other listed products, enclosures, orassemblies providing weatherproof protection that do not utilize an outlet box hood need not be marked “extraduty.”



All 15- and 20-ampere, 125- and through 250-volt nonlocking-type receptacles shall be listed and so identifiedas the weather-resistant type.



The current text of section 406.9(B)(1) references receptacles of 120 and 250 volts. By this reference 208 volt receptacles may not be considered to be addressed in the requirements of this section. The exception to this section addresses receptacles of 120 through 250 volts thus including 208 volt. The proposed revision would make the body of the text consistent with the language of the exception.

The proposed language is directly from Section 410.10(D), which provides specific dimensions for electrical installations near bathtubs and shower stalls.

Grounding-type receptacles, cord connectors, and attachment plugs shall be provided with one fixed groundingpole connection in addition to the circuit poles connections . The grounding contacting pole of grounding-typeplug-in ground-fault circuit interrupters shall be permitted to be of the movable, self-restoring type on circuitsoperating at not over 150 volts between any two conductors or any conductor and ground.

(B) Grounding -Pole Connection Identification.

Grounding-type receptacles, adapters, cord connections, and attachment plugs shall have a means forconnection of an equipment grounding conductor to the grounding pole connection means .

A terminal for connection to the grounding pole shall be designated by one of the following:

(1) A green-colored hexagonal-headed or -shaped terminal screw or nut, not readily removable.

(2) A green-colored pressure wire connector body (a wire barrel).

(3) A similar green-colored connection device, in the case of adapters. The grounding terminal of a groundingadapter shall be a green-colored rigid ear, lug, or similar device. The equipment grounding connection shallbe so designed that it cannot make contact with current-carrying parts of the receptacle, adapter, orattachment plug. The adapter shall be polarized.

(4) If the terminal for the equipment grounding conductor is not visible, the conductor entrance hole shall bemarked with the word green or ground, the letters G or GR, a grounding symbol, or otherwise identified bya distinctive green color. If the terminal for the equipment grounding conductor is readily removable, thearea adjacent to the terminal shall be similarly marked.

Informational Note: See Informational Note Figure 406.10(B)(4) .

Figure Informational Note Figure 406.10(B)(4) One Example of a Symbol Used to Identify theTermination Point for an Equipment Grounding Conductor.

(C) Grounding Terminal Use.

A grounding terminal shall not be used for purposes other than grounding.


1 of 2 10/4/2017, 3:06 PM

(D) Grounding -Pole Connection Requirements.

Grounding-type attachment plugs and mating cord connectors and receptacles shall be designed such that theequipment grounding connection is made before the current-carrying connections. Grounding-type devices shallbe so designed that grounding poles of attachment plugs cannot be brought into contact with current-carryingparts of receptacles or cord connectors.

(E) Use.

Grounding-type attachment plugs shall be used only with a cord having an equipment grounding conductor.

Informational Note: See 250.126 for identification of grounding conductor terminals.


What is a grounding pole? This term may be known by some, but it is not defined and introduces an inconsistency. The terminology should be consistent with the terms used article 250. The proposed revision should be an improvement in clarity and for all users.

(E) Use.

Grounding-type attachment plugs shall be used only with a cord having an equipment grounding conductor.

Informational Note: See 250.126 for identification of equipment grounding conductor terminals.


Grounding and bonding still continues to be one of the most misunderstood and misapplied sections of the NEC. Most of the problems can be traced back to using undefined terminology (trade slang in many cases) or incorrect terminology. The term “grounding conductor” is one that is no longer defined. As part of a Correlating Committee Task Force activity on grounding and bonding in general, this term and its related definition was removed from the NEC during the 2008 NEC cycle. The term had been found to be misapplied in a number of instances and the definition of “grounding conductor” was determined to be very close to the definition of “grounding electrode conductor” yet, many uses of the term in previous editions of the NEC were found to be more correctly to be either “equipment grounding conductor”, “grounding electrode conductor” or one of the several types of “bonding jumper”.

The revised text uses terms defined in the Code and is consistent with the context of the meaning of the section where the revisions are made. The revisions are made to provide clarity, and consistency in terminology usage.

It is requested the Correlating Committee consider a policy or procedures that require a review when a term under the responsibility of a specific Code panel is used by another Code panel. The panel responsible for the term is to review the application to ensure correct usage. It is further requested that when new terms are created that would be identified as under the responsibility of another Code panel that the new term and application be reviewed by the Code panel that would have responsibility for use and application.

Article 406.12(1) states "dwelling units" and continues to state in all areas in 210.52 and 550.13. Personal experience has shown many electrical contractors do not believe tamper-resistant receptacles are required in detached garages and accessory buildings due to the text stating "dwelling units". Changing the text will clear up the requirement for the use of tamper-resistant receptacles in detached garages and all accessory buildings to dwelling units.

Assisted Living Facilities which are being opened all around the country are essentially dwelling units but don’t come under the present definition of dwelling units as per Article 100 of NEC 2017 as most of the times these units don’t have permanent provision for cooking.

Public Input No. 1457-NFPA 70-2017 [ New Article after 406 ]

406.13 Single-Pole Separable Connector Type and Identification.Single-pole separable connectors shall be listed and shall comply with the following:

A) Locking or Latching Type. Single-pole separable connectors shall be of either the locking orlatching type and marked with the manufacturer’s name or identification and voltage and ampere ratings.

B) Identification. Connectors designated for connection to the grounded circuit conductor shall beidentified by a white-colored housing; connectors designated for connection to the grounding circuit conductorshall be identified by a green-colored housing.

C) Interchangeability. Single-pole separable connectors shall be permitted to be interchangeable forac or dc use or for different current ratings or voltages on the same premises, provided they are listed for ac/dcuse and marked in a suitable manner to identify the system to which they are intended to be connected.


Article 406 does not address single pole separable connectors nor does it require a single pole separable connector to be listed.

Single-pole separable connectors are widely available in the market place and are used in a variety of applications, including land transportation, non-hazardous refinery and mining operations.

The nationally recognized product standard for single pole separable connectors, ANSI/UL 1691 contains requirements that correspond to the required construction as well as the performance and marking requirements to evaluate the suitability of a single pole separable connector. Requiring the use of a listed single pole separable connector will confirm that the installed device complies with the required characteristics of 406.13.

Sections 520.53(C) and 530.22 are the source of these requirements.

Article 406 contains requirements for a variety of different types of plugs and receptacles such as receptacle with USB charger, tamper resistant receptacles and weather-resistant receptacles. However, the Article does not address single pole separable connectors, which are widely available in the market place. The proposed text identifies their proper connection and disconnection sequence, necessary for the safe use of these devices.

Sections 520.53(C) and 530.22 are the source of these requirements.

410.6 Listing Required.

All luminaires, lampholders, and retrofit kits shall be listed or field labeled .


Field labeling of luminaires needs to be a viable option just as section 230.66 allows it for high voltage service equipment, 690.12(B)(2)(1) allows it for rapid shut-down systems for PV installations, 690.4(B) allows it for PV equipment, 692.6 allows it for Fuel Cell Systems, 694.7(B) allows it for wind electric systems, 705.6 allows it for interconnected power production equipment, 705.170(2) allows it for microgrid interconnected devices and 710.6 allows it for stand alone systems. Sometimes luminaires are custom-built one-of-a-kind pieces of art! The owner, installer and AHJ should have the option of allowing a representative of a testing lab to perform an on-site inspection of the luminaire to insure that the fixture meets all industry safety standards. If it does, then the fixture could be "field labeled" indicating that it should be considered just as safe as a fixture that was sent to a lab to be "listed". The AHJ would ultimately still have the prerogative to approve or disapprove of this "field labeled" fixture. Without this option, the owner, the installer, and the AHJ only have the option of not allowing his fixture to be installed. This is too restrictive for a fixture that may be completely safe.

✓


The content of Sections 410.70 and 410.82 (A and B) is fully addressed by ANSI/UL 153, Standard for Portable Electric Lamps, and applied by the Listing requirement of 410.6. Eliminating this content relieves AHJs from any burden to evaluate the materials and construction of these otherwise listed products. It is highly unlikely, in any case, that AHJs are involved in approving the installation of these easily transported portable, cord/plug connected products which are typically brought into a facility after all permitting processes are completed.

The luminaire product standards (UL 1598, UL 153, and others) all address lamp wattage where the luminaire uses a replaceable lamp.

There are many LED luminaires that do not use “lamps” and in some cases the light source is not even user replaceable. The proposed revisions to 410.74 ensure that the information needed for branch circuit capacity and compatibility is retained, but defers to the product standard for additional user maintenance markings (of which lamp replacement may be only one of many).

Renaming this section to “Marking of Luminaires” is a better fit for the remaining content.

Part VII. ConstructionMarking of Luminaires 410.70 Combustible Shades and Enclosures. Adequate airspace shall be provided between lamps and shades or other enclosures of combustible material. 410.74 Luminaire Rating. (A) Marking. All luminaires shall be marked with the maximum lamp wattage or electrical rating, manufacturer’s name, trademark, or other suitable means of identification. A luminaire requiring supply wire rated higher than 60°C (140°F) shall be marked with the minimum supply wire temperature rating on the luminaire and shipping carton or equivalent. (B) Electrical Rating. The electrical rating shall include the voltage, and frequency and shall indicate the current or wattagerating of the unit, including any integral light source,the ballast, transformer, LED driver, power supply, or autotransformer. 410.82 Portable Luminaires. (A) General. Portable luminaires shall be wired with flexible cord recognized by 400.4 and an attachment plug of the polarized or grounding type. Where used with Edison-base lampholders, the grounded conductor shall be identified andattached to the screw shell and the identified blade of the attachment plug. (B) Portable Handlamps. In addition to the provisions of 410.82(A), portable handlamps shall comply with the following: (1) Metal shell, paper-lined lampholders shall not be used. (2) Handlamps shall be equipped with a handle of molded composition or other insulating material. (3) Handlamps shall be equipped with a substantial guard attached to the lampholder or handle. (4) Metallic guards shall be grounded by means of an equipment grounding conductor run with circuit conductors within the power-supply cord. (5) Portable handlamps shall not be required to be grounded where supplied through an isolating transformer with an ungrounded secondary of not over 50 volts.

Substantiation:

The content of Sections 410.70 and 410.82 (A and B) is fully addressed by ANSI/UL 153, Standard for

Portable Electric Lamps, and applied by the Listing requirement of 410.6. Eliminating this content

relieves AHJs from any burden to evaluate the materials and construction of these otherwise listed

products. It is highly unlikely, in any case, that AHJs are involved in approving the installation of these

easily transported portable, cord/plug connected products which are typically brought into a facility

after all permitting processes are completed.

The luminaire product standards (UL 1598, UL 153, and others) all address lamp wattage where the

luminaire uses a replaceable lamp. There are many LED luminaires that do not use “lamps” and in some

cases the light source is not even user replaceable. The proposed revisions to 410.74 ensure that the

information needed for branch circuit capacity and compatibility is retained, but defers to the product

standard for additional user maintenance markings (of which lamp replacement may be only one of

many).

Many newly constructed large residential homes contain a master bedroom walk-in closet that is larger than 100 square feet. In the center of the closet homeowners are wanting to install a ceiling chandelier which contains many small incandescent bulbs. 410.16(B) currently does not allow for this to be done. Unfortunately as inspectors, we are seeing homeowners install an inexpensive enclosed surface mounted light until the electrical inspection has passed, then installing the desired chandelier. By allowing a provision in large walk-in closets for incandescent bulbs would outline acceptable standards that can be followed.

(B) Access to Boxes. Access to junction boxes supplying electric-discharge and LED luminaires shall be inaccordance with (B)(1) and (B)(2).

(1) Surface Mounted. Electric-discharge and LED luminaires surface mounted over concealed outlet, pull, orjunction boxes and designed not to be supported solely by the outlet box shall be provided with suitableopenings in the back of the luminaire to provide access to the wiring in the box.

(2) Recessed Mounted. Electric-discharge and LED luminaires recessed in celings, floors or walls shall not beused to access outlet, pull or junction boxes or conduit bodies not associated with the wiring of the luminaire.


The intent of the proposed revision is to clarify that a luminaire cannot be used to access junction boxes that are not associated with wiring for the luminaire. A companion public input has been submitted to CMP 9 to similarly revise 314.29 regarding junction boxes.

On more than one occasion installations were made where recessed luminaires that were actually fastened to structural components of a dropped ceiling were intended to be used to access junction boxes for wiring that was not associated with the luminaire. In these types of ceilings there are no removable ceiling tiles so the junction boxes are not visible or accessible without the removal of the luminaire. Unless the luminaire was to be considered part of the building finish, there is no clear language prohibiting this type of installation.

This proposal, in combination with the revision proposals for 410.44 and 410.46, simplifies the requirements for protection against electric shock injury associated with luminaires with accessible conductive surfaces. It does so as follows:1) In 410.42, replace the phrase “insulated from the equipment grounding conductor and other conducting surfaces” with the more precise (but conceptually equivalent) phrase “separated from the equipment grounding conductor and other conducting surfaces by double insulation.” Double insulation is already permitted by exception 3 to 250.110 as an alternative to grounding.2) Add an exception for the polarized plug connection of portable luminaires that is currently permitted by 410.82. The exception need not make explicit reference to 410.82 because the polarization allowance and associated requirements are addressed by the product standard (UL 153) associated with the listing requirement of 410.6.3) Shift the ‘method of grounding’ requirements (the reference to 250.118 and 250.122) from 410.44 into 410.42, eliminating the need for a separate 410.44.4) Eliminate exception #1 to 410.44. There is no requirement for a luminaire with no accessible conductive parts, or ‘made of insulating material’, to be grounded. Hence, there is no need to exempt it from the grounding requirement. Additionally, the phrase ‘made of insulating material’ is overly broad (only the accessible surfaces, and not the entire luminaire, need to be of insulating material), and insulating material is only a reliable safeguard if that insulating material meets the double insulation threshold (as proposed for 410.42).5) Eliminate exception #2 to 410.44. The reference to 250.130(C) has no relevance here, as that clause describes the means to provide grounding at a receptacle where it currently does not exist. It has no bearing on how a luminaire subsequently connects to the grounding conductor.6) Eliminate 410.46. This is a product (luminaire) requirement that is addressed by the Listing requirement of 410.6.

Editorially, shifting the last phrase of 410.42 into an exception (no. 1) brings clarity to the basic requirement. Adding the phrase “…small isolated parts such as” allows this exemption to be applied more flexibly. A Google search for the term “lamp tie wires” does not reveal anything specific, but this more flexible phrasing should allow such a part (if conductive, small, and isolated) to remain permitted.

410.42 Luminaire(s) with Exposed Conductive Parts. Exposed conductivemetal parts that are accessible to unqualified persons shall be connected to an equipment grounding conductor in accordance with 250.118 and sized in accordance with 250.122, or be separatedinsulated from the equipment grounding conductor and other conducting surfaces by double insulation.or be inaccessible to unqualified personnel.

Exception No. 2: Replacement luminaires shall be permitted to connect an equipment grounding conductor from the outlet in compliance with 250.130(C). The luminaire shall then comply with 410.42. Exception No. 3: Where no equipment grounding conductor exists at the outlet, replacement luminaires with exposed conductive parts that are GFCI protected shall not be required to be connected to an equipment grounding conductor. 410.46 Equipment Grounding Conductor Attachment. Luminaires with exposed metal parts shall be provided with a means for connecting an equipment grounding conductor for such luminaires.

Substantiation:

This proposal simplifies the requirements for protection against electric shock injury associated with

luminaires with accessible conductive surfaces. It does so as follows:

1) In 410.42, replace the phrase “insulated from the equipment grounding conductor and other

conducting surfaces” with the more precise (but conceptually equivalent) phrase “separated

from the equipment grounding conductor and other conducting surfaces by double insulation.”

Double insulation is already permitted by exception 3 to 250.110 as an alternative to grounding.

Formatted: Font: Not Bold, Italic




2) Add an exception for the polarized plug connection of portable luminaires that is currently

permitted by 410.82. The exception need not make explicit reference to 410.82 because the

polarization allowance and associated requirements are addressed by the product standard (UL

153) associated with the listing requirement of 410.6.

3) Shift the ‘method of grounding’ requirements (the reference to 250.118 and 250.122) from

410.44 into 410.42, eliminating the need for a separate 410.44.

4) Eliminate exception #1 to 410.44. There is no requirement for a luminaire with no accessible

conductive parts, or ‘made of insulating material’, to be grounded. Hence, there is no need to

exempt it from the grounding requirement. Additionally, the phrase ‘made of insulating

material’ is overly broad (only the accessible surfaces, and not the entire luminaire, need to be

of insulating material), and insulating material is only a reliable safeguard if that insulating

material meets the double insulation threshold (as proposed for 410.42).

5) Eliminate exception #2 to 410.44. The reference to 250.130(C) has no relevance here, as that

clause describes the means to provide grounding at a receptacle where it currently does not

exist. It has no bearing on how a luminaire subsequently connects to the grounding conductor.

6) Eliminate 410.46. This is a product (luminaire) requirement that is addressed by the Listing

requirement of 410.6.

Editorially, shifting the last phrase of 410.42 into an exception (no. 1) brings clarity to the basic

requirement. Adding the phrase “…small isolated parts such as” allows this exemption to be applied

more flexibly. A Google search for the term “lamp tie wires” does not reveal anything specific, but this

more flexible phrasing should allow such a part (if conductive, small, and isolated) to remain permitted.

The current exception no. 3 to 410.46 is shifted to exception no. 3 to 410.42, with a minor adjustment to

limit the application to only luminaires with exposed conductive parts.


410.44 Methods of Connection to the Equipment Grounding Conductor .

Luminaires and equipment shall be mechanically connected to an equipment grounding conductoras specified in 250.118 and sized in accordance with Article 250. 122.

Exception No. 1: Luminaires made of insulating material that is directly wired or attached to outletssupplied by a wiring method that does not provide a ready means for grounding attachment to anequipment grounding conductor shall be made of insulating material and shall have no exposedconductive parts.

Exception No. 2: Replacement luminaires shall be permitted to connect an equipment groundingconductor from the outlet in compliance with 250.130(C). The luminaire shall then comply with410.42.

Exception No. 3: Where no equipment grounding conductor exists at the outlet, replacementluminaires that are GFCI protected shall not be required to be connected to an equipmentgrounding conductor.

All of these requirements have, for years, been contained within the applicable product standards (UL 1598, UL 153, and others). There is no need for AHJs to directly examine these particular features of luminaires; at the time these requirements were introduced to the NEC, they may have represented the full set of relevant product safety requirements associated with luminaires. That is (and has been) no longer the case, so removing this content will fully unburden AHJs from this implied responsibility and allow them to simply enforce the Listing requirement of 410.6.

Part VI. Wiring of Luminaires 410.48 Luminaire Wiring — General. Wiring on or within luminaires shall be neatly arranged and shall not be exposed to physical damage. Excess wiring shall be avoided. Conductors shall be arranged so that they are not subjected to temperatures above those for which they are rated. 410.50 Polarization of Luminaires. Luminaires shall be wired so that the screw shells of lampholders are connected to the same luminaire or circuit conductor or terminal. The grounded conductor, where connected to a screw shell lampholder, shall be connected to the screw shell. 410.52 Conductor Insulation. Luminaires shall be wired with conductors having insulation suitable for the environmental conditions, current, voltage, and temperature to which the conductors will be subjected. Informational Note: For ampacity of fixture wire, maximum operating temperature, voltage limitations, minimum wire size, and other information, see Article 402. 410.54 Pendant Conductors for Incandescent Filament Lamps. (A) Support. Pendant lampholders with permanently attached leads, where used for other than festoon wiring, shall be hung from separate stranded rubber-covered conductors that are soldered directly to the circuit conductors but supported independently thereof. (B) Size. Unless part of listed decorative lighting assemblies, pendant conductors shall not be smaller than 14 AWG for mogul-base or medium-base screw shell lampholders or smaller than 18 AWG for intermediate or candelabra-base lampholders. (C) Twisted or Cabled. Pendant conductors longer than 900 mm (3 ft) shall be twisted together where not cabled in a listed assembly. 410.56 Protection of Conductors and Insulation. (A) Properly Secured. Conductors shall be secured in a manner that does not tend to cut or abrade the insulation. (B) Protection Through Metal. Conductor insulation shall be protected from abrasion where it passes through metal. (C) Luminaire Stems. Splices and taps shall not be located within luminaire arms or stems. (D) Splices and Taps. No unnecessary splices or taps shall be made within or on a luminaire.

Informational Note: For approved means of making connections, see 110.14.

(E) Stranding. Stranded conductors shall be used for wiring on luminaire chains and on other movable or flexible parts. (F) Tension. Conductors shall be arranged so that the weight of the luminaire or movable parts does not put tension on the conductors.

Substantiation:

The content of Part VI is fully addressed by the Listing requirement of 410.6. All of these requirements

have, for years, been contained within the applicable product standards (UL 1598, UL 153, and others).

There is no need for AHJs to directly examine these particular features of luminaires; at the time these

requirements were introduced to the NEC, they may have represented the full set of relevant product

safety requirements associated with luminaires. That is (and has been) no longer the case, so removing

this content will fully unburden AHJs from this implied responsibility and allow them to simply enforce

the Listing requirement of 410.6. Simplifying and shortening the NEC also has certain other benefits.


410.48 Luminaire Wiring and Marking — General.

Wiring on or within luminaires shall be neatly arranged and shall not be exposed to physical damage. Excesswiring shall be avoided. Conductors shall be arranged so that they are not subjected to temperatures abovethose for which they are rated.

(B) Retrofit Wiring. Luminaires with a retrofitted illumination system shall meet the requirements in (1) through(5) below.

(1) Retrofit kits installed in luminaire(s) shall be installed in accordance with the manufacturer’s installationinstructions.

(2) The retrofitted luminaire(s) shall be marked that the illumination system has been replaced and themarking shall be permitted to be located on the outside of the luminaire or on the inside where visible from thewiring compartment.

(3) The marking shall include the kit providers and installer’s name, logo, or unique identifier.

(4) Luminaire(s) equipped with tubular light-emitting diode lamps powered by the existing luminaire tubesockets shall include a label alerting the service personnel that the luminaire has been modified. The label shallalso include a warning not to install fluorescent lamps and shall also be visible during relamping.

(5) The label shall meet the requirements of 110.21(B).


This Public Input intends to expand this requirement into two separate subdivisions dealing with wiring and marking. These new requirements for retrofit wired luminaires mirror those for electric signs and outline lighting systems that were added in Section 600.4(B) in the 2017 NEC development process. The concerns and hazards are the same and same need for labeling exists in the many luminaires that are being rewired with retrofit kits.

The word “directly” is not necessary. The exact horizontal location of existing (or proposed) outlets should not be a factor in establishing the lighting distribution pattern in the facility. This section addresses high bay and similar pendant luminaires, and it should not matter if their mechanical support causes the supply cord to run other than perfectly vertical.Subsection (a) also describes a product type commonly known as a “shop light”. These products are used in many locations, from light industrial to commercial/retail to home workshops. Listing is available under both UL 1598 (fixed luminaires) and UL 153 (portable luminaires). The grounding-type attachment plug requirement has become a contentious issue in the context of UL 153 because the level of hazard associated with these products is not noticeably different from that of other portable luminaires where (per 410.82) a polarized plug is permitted. The UL 153 standard requires the cord of such products to be minimum hard usage or be otherwise protected from mechanical damage.The proposed revision in subsection (a) would provide relief to listed portable luminaire shop lights by tying the need for a grounding-type plug to the grounding requirements of 410.42. Shop lights with no accessible conductive parts would be permitted to use a polarized plug under the current text of 410.42; additional (listed) designs could be permitted to use a polarized plug depending on the CMP’s actions in regards to other 2020 NEC proposals.

410.69 Identification of Control Conductors . Where control conductors are spliced, terminated or connected in the sameluminaire or enclosure as the branch circuit conductors, the control conductors shall not be of the same color as any of theungrounded or grounded branch circuit conductors supplying the luminaire.


This public input intends to prevent lighting control conductors from being installed using the same color as the branch circuit conductors. This is based upon multiple shock incidents that have occurred. One common control conductor scheme is to use "purple and gray" colored control conductors. 200.6(A) specifically permits white and gray to be used in the identification of grounded conductors.The shock incidents occurred where "gray control" conductors were inadvertently spliced to the grounded conductor. The lighting control conductors are not limited to control of a single branch circuit, they can control multiple branch circuits. This sets up a scenario where employees are working on a branch circuit that has been placed into an electrically safe work condition but an inadvertently spliced common control conductor in a luminaire becomes energized when a completely different branch circuit is energized.This is a logical, feasible safety driven revision. There is no logical reason to continue using colors identified for branch circuits as control conductors. In discussions with the lighting control manufacturer involved there was significant consensus that this revision be adopted.

410.82 Portable Luminaires.

(A) General.

Portable luminaires shall be wired with flexible cord recognized by 400.4 and an attachment plug of thepolarized or grounding type. Where used with Edison-base lampholders, the grounded conductor shall beidentified and attached to the screw shell and the identified blade of the attachment plug.

(B) Portable Handlamps.

In addition to the provisions of 410.82(A) , portable handlamps shall comply with the following:

(1) Metal shell, paper-lined lampholders shall not be used.

(2) Handlamps shall be equipped with a handle of molded composition or other insulating material.

(3) Handlamps shall be equipped with a substantial guard attached to the lampholder or handle.

(4) Metallic guards shall be grounded by means of an equipment grounding conductor run with circuitconductors within the power-supply cord.

(5) Portable handlamps shall not be required to be grounded where supplied through an isolating transformerwith an ungrounded secondary of not over 50 volts.




✓



The luminaire product standards (UL 1598, UL 153, and others) all address lamp wattage where the luminaire uses a replaceable lamp. There are many LED luminaires that do not use “lamps” and in some cases the light source is not even user replaceable. The proposed revisions to 410.74 ensure that the information needed for branch circuit capacity and compatibility is retained, but defers to the product standard for additional user maintenance markings (of which lamp replacement may be only one of many).

(B) Fire-Resistant Construction.

Where a luminaire is recessed in fire-resistant material in a building of fire-resistant construction

, a temperature higher than 90°C (194°F) but not higher than 150°C (302°F) shall be considered acceptable ifthe luminaire is plainly marked for that service.

the recessed luminaire shall satisfy one of the following:

(1) The recessed luminaire shall be listed for use in a fire resistance rated construction;

(2) Be installed in or used with a luminaire enclosure that is listed for use in a fire resistance ratedconstruction; or

(3) Be listed and shall be installed in accordance with a tested fire resistance rated assembly.

Exception: Luminaires marked "FOR USE IN NON-FIRE RATED INSTALLATIONS" shall not be used in firerated installations.


This section does a nice job of summarizing the temperature limitations for the installation recessed luminaires that are found in the Standard for Luminaires, UL 1598. However, the current text does not address all the requirements necessary to ensure full compliance.

Other essential guidelines such as fire resistance rated marking and labeling, the requirements for fastening and fasteners, the size and number of openings permitted in luminaire housings, the minimum metal thickness for luminaire enclosures, applications for continuous row installations, just to name a few.

In special environments such as fire-resistance rated construction, it is proper for the standard to contain the tests, limits and construction specifics, not the NEC.

The existing code text with only temperature requirements and with no means of verification is insufficient. Testing that includes all the applicable considerations and subsequent listing of a fire resistance rated assembly and luminaire by an NRTL takes away the guesswork for the installer, contractor, and electrical inspector in the field.

TITLE OF NEW CONTENT

Part XVI. Special Provisions for Horticultural Lighting Equipment

410. 162 General. The provisions in Part VXI of this article shall apply to lighting equipment intended for usein a horticultural environment.

Informational Note: Horticultural Lighting equipment is designed to provide photosynthetic support forplants.

410.164 Listing. Horticultural lighting equipment shall be listed and installed in conformance with that listing.

410.166 Identification . Horticultural lighting equipment shall be identified as suitable for the installation andthe environment for which they are designed.

410.168 Locations Not Permitted . Horticultural lighting equipment shall not be installed in the followinglocations:

(1) Where likely to be subjected to physical damage

(2) Where concealed

410.170 Flexible Cord. Flexible cord may be used to:

a) connect a horticultural a lighting luminaire to a branch circuit

b) interconnect horticultural lighting luminaires, or

c) connect a horticultural lighting luminaire to a remote power source.

Informational Note: Remote power sources include LED drivers, fluorescent ballasts, or HID ballasts.

410.172 Flexible Cords and Associated Connectors. Flexible cords and associated connectors shall:

a) be provided as part of a listed horticultural lighting equipment device or system

b) be installed in accordance with the instructions provided as part of that listing

410.174 Support . Special fittings identified for support of horticultural lighting equipment shall be designedspecifically for the horticultural lighting equipment on which they are installed and shall be:

a) used in accordance with the installation instructions provided, and

b) be securely fastened

410.176 Metal Halide Lamps . Horticultural lighting equipment that use metal halide lamps shall be markedwith relamping information indicating the correct lamp to be installed.

410.178 Hazardous (Classified) Locations. Where installed in hazardous (classified) locations, horticulturallighting equipment shall conform to Articles 500 through 517 in addition to this article.


With the advent of special plant growth LED sources and discharge lamps, and the increase of indoor plant growing facilities, horticultural lighting equipment is a rapidly expanding technology. While Article 547 has requirements for agricultural buildings, horticultural lighting installations have special considerations not currently addressed by the Code. In 2017 UL published UL8800, containing the safety requirements for horticultural lighting equipment, Code requirements are needed to align with these listing requirements to ensure safe installation and to facilitate inspection of horticultural lighting equipment installations. Environmental conditions that horticultural lighting equipment may be exposed to (e.g. ambient temperature, humidity & water spray) are considered by equipment listing and it is essential that these factors are addressed during installation and inspection. Because horticultural lighting equipment needs to be adjustable to accommodate plant growth, flexible connection to branch circuits is necessary. Also, horticultural lighting equipment has unique support requirements that need to be addressed. Since this is a lighting technology, it is appropriate to address it in Article 410.

410.177 Grounding. Lighting equipment identified for horticultural use shall be grounded as requiredin Article 250 and Part V of this article.

410.178 Support . Support hardware for lighting equipment identified for horticultural use shall be ofmaterials suitable for the environment in which they are to be installed and be securely fastened.


With the increasing numbers of indoor plant growing facilities being established, horticultural lighting equipment providing a wavelength(s) of light necessary for plant growth has become a rapidly expanding technology. New horticultural lighting equipment designs are driven by the availability of LED light sources that allow precise tuning of the spectral output, low radiated temperatures, low energy consumption and long life. Also, horticultural lighting equipment using legacy light source technologies, including fluorescent and high intensity discharge (HID) continue to be widely used.

While the Code has provisions for agricultural buildings in Article 547, the newer indoor horticultural lighting installations demand different considerations. In addition, installation of such lighting is different than that of ordinary general illumination lighting equipment as presently addressed in Article 410.

UL published an Outline of Investigation for Horticultural Lighting Equipment (UL 8800) in 2017. This publication contains the requirements essential for the equipment safety. However, the Code does not directly address the often unique installations and, since horticultural lighting equipment installations are becoming more and more common,


1 of 2 10/4/2017, 11:00 PM

Code requirements are needed to ensure safe installations and to facilitate inspection. For example, since horticultural lighting equipment needs to be adjustable to accommodate seasonal plant diversity and growth, flexible connection to branch circuits and between luminaires is provided. Also, horticultural lighting equipment is typically installed in close proximity to each other in a manner different than general illumination, and can have unique support from structures in the environment. Additionally, the environment for this equipment can be challenging. It is essential that these factors are appropriately addressed in the Code.

(B) Assembly of Listed Parts.

A lighting system assembled from the following listed parts shall be permitted:

(1) Low-voltage luminaires

(2) Power Class 2 power supply

(3) Low-voltage luminaire fittings

(4) Suitably rated cord, cable, conductors in conduit, or other fixed Chapter 3wiring method for thesecondary circuit


The power supply is the only control of this type of free lance field wiring. The last cycle allowed the removal of Class 2 power supplies in lieu of Listing. This also allowed the power supply to have more output current as long as the system was listed. This is suitable, based on 411.4 (A) requiring listing. This will place the responsibility on the listing service to evaluate the system as safe from electric shock but not from fire initiation. Adding Class 2 requirements to 411.4 (B) returns the level of safety of field selection of listed Class 2 power supplies while allowing the option 411.4 (A) to use stronger power supplies when listed as a system.

Insulated secondary circuit conductors shall be of the type, and installed as, described in (1), (2), or (3):

(1) Class 2 cable supplied by a Class 2 power source and installed in accordance with Parts I and III ofArticle 725 .

(2) Conductors, cord, or cable of the listed system and installed not less than 2.1 m (7 ft) above the finishedfloor unless the system is specifically listed for a lower installation height.

(3) Wiring methods described in Chapter 3 .



2020_NEC_Art_411_proposals.docx Word version of 411.6(D) deletion proposal Shulman ✓


The term “insulated conductors” has been consistently misunderstood in this context and possibly applied to a much broader range of luminaires than intended. The term as used here is intended to contrast with the “bare conductors” referred to in 411.6(C). In both 411.6(C) and (D), the requirements are directed at trapeze lighting systems which typically allow their suspended/supported low voltage luminaires to be repositioned along the trapeze bars. These decorative fixtures present an unusual heat/fire hazard scenario because the parallel (low voltage but opposite polarity) trapeze bars can be shorted by placement of metal object across them (such as jewelry or an eating utensil). The NEC recognizes and generally avoids this hazard scenario through the 7 foot minimum installation height that appears in both 411.6(C) and 411.6(D)(2).

The construction and performance requirements for these systems are addressed by UL 2108, Standard for Low Voltage Lighting Systems. Systems with bare conductors [411.6(C)] are restricted for use with only power units that have integral protection against the inadvertent shorting discussed above. Systems with insulated conductors [411.6(D)] are instead evaluated to validate that their insulated coating is sufficient (electrically and/or mechanically) to prevent this type of shorting. The insulated conductors that are only electrically evaluated are limited to installation above 7 feet; this limit is a required element of their installation instructions. Those with a more robust coating that complies with the mechanical evaluation requirements do not have this installation height restriction. 411.6(D)(2) acknowledges this variability through the phrase “…unless the system is specifically listed for a lower installation height”; however, the Standard actually only address installation height when it is restricted to above 7 feet. An insulated conductor system without this restriction could claim that it is suitable for installation at a lower height, of course.

411.6(C) has a similar allowance for a less than 7 foot high installation but bare conductor systems are best installed above that height to avoid nuisance tripping (they are evaluated to shut down safely, but they do shut down). This proposal is not recommending deletion of 411.6(C) as it has not been subject to the confusion or misapplication that has occurred with 411.6(D).

There is no need for 411.6(D)(1) to explicitly authorize class 2 cable to be supplied by a class 2 power source, or for 411.6(D)(3) to allow the use of a chapter 3 wiring method. The remaining requirement of 411.6(D)(2) is fully addressed by the Listing requirement of 411.4 which in turn requires evaluation per UL 2108. Elimination of 411.6(D) will shorten and simplify application of Article 411, removing some confusion but not changing any actual product or installation requirements.

411.6 (D) Insulated Conductors. Insulated secondary circuit conductors shall be of the type, and installed as, described in (1), (2), or (3): (1) Class 2 cable supplied by a Class 2 power source and installed in accordance with Parts I and III of Article 725. (2) Conductors, cord, or cable of the listed system and installed not less than 2.1 m (7 ft) above the finished floor unless the system is specifically listed for a lower installation height. (3) Wiring methods described in Chapter 3.

Substantiation:

The term “insulated conductors” has been consistently misunderstood in this context and possibly

applied to a much broader range of luminaires than intended. The term as used here is intended to

contrast with the “bare conductors” referred to in 411.6(C). In both 411.6(C) and (D), the requirements

are directed at trapeze lighting systems which typically allow their suspended/supported low voltage

luminaires to be repositioned along the trapeze bars. These decorative fixtures present an unusual

heat/fire hazard scenario because the parallel (low voltage but opposite polarity) trapeze bars can be

shorted by placement of metal object across them (such as jewelry or an eating utensil). The NEC

recognizes and generally avoids this hazard scenario through the 7 foot minimum installation height that

appears in both 411.6(C) and 411.6(D)(2).

The construction and performance requirements for these systems are addressed by UL 2108, Standard

for Low Voltage Lighting Systems. Systems with bare conductors [411.6(C)] are restricted for use with

only power units that have integral protection against the inadvertent shorting discussed above.

Systems with insulated conductors [411.6(D)] are instead evaluated to validate that their insulated

coating is sufficient (electrically and/or mechanically) to prevent this type of shorting. The insulated

conductors that are only electrically evaluated are limited to installation above 7 feet; this limit is a

required element of their installation instructions. Those with a more robust coating that complies with

the mechanical evaluation requirements do not have this installation height restriction. 411.6(D)(2)

acknowledges this variability through the phrase “…unless the system is specifically listed for a lower

installation height”; however, the Standard actually only address installation height when it is restricted

to above 7 feet. An insulated conductor system without this restriction could claim that it is suitable for

installation at a lower height, of course.

411.6(C) has a similar allowance for a less than 7 foot high installation but bare conductor systems are

best installed above that height to avoid nuisance tripping (they are evaluated to shut down safely, but

they do shut down). This proposal is not recommending deletion of 411.6(C) as it has not been subject

to the confusion or misapplication that has occurred with 411.6(D).

There is no need for 411.6(D)(1) to explicitly authorize class 2 cable to be supplied by a class 2 power

source, or for 411.6(D)(3) to allow the use of a chapter 3 wiring method. The remaining requirement of

411.6(D)(2) is fully addressed by the Listing requirement of 411.4 which in turn requires evaluation per

UL 2108. Elimination of 411.6(D) will shorten and simplify application of Article 411, removing some

confusion but not changing any actual product or installation requirements.


600.2 Definitions. The definitions in this section shall apply only within this article.

LED Sign Illumination System.

A complete lighting system for use in signs and outline lighting consisting of light-emitting diode (LED) lightsources, power supplies, wire, and connectors to complete the installation.

Neon Tubing.

Electric-discharge luminous tubing, including cold cathode luminous tubing, that is manufactured into shapes toilluminate signs, form letters, parts of letters, skeleton tubing, outline lighting, other decorative elements, or artforms and filled with various inert gases.

Photovoltaic (PV) Powered Sign.

A complete sign powered by solar energy consisting of all components and subassemblies for installation eitheras an off-grid stand-alone, on-grid interactive, or non-grid interactive system.

Section Sign.

A sign or outline lighting system, shipped as subassemblies, that requires field-installed wiring between thesubassemblies to complete the overall sign. The subassemblies are either physically joined to form a singlesign unit or are installed as separate remote parts of an overall sign.

Sign Body.

A portion of a sign that may provide protection from the weather but is not an electrical enclosure.

Skeleton Tubing.

Neon tubing that is itself the sign or outline lighting and is not attached to an enclosure or sign body.





The definition of the term “rigid metal conduit” is appropriately located in the article that contains general, installation and construction specifications for this raceway. It is commonly understood that the term “rigid metal conduit” is used in more than one article. There are many articles that contain a single definition that is necessary for application of the contained requirements but will apply elsewhere in the NEC. This occurs in articles that address cable assemblies, raceways, systems and more.This public input seeks to delete the last sentence in the first paragraph, as it is unnecessary. A new sentence is proposed to simply inform the user of the code that definitions are also found in the second section (XXX.2) of other articles.This public input is supplemented with proposed revisions to the second section (XXX.2) of articles that contain


1 of 2 10/4/2017, 11:02 PM

definitions. New parent text is proposed for these sections to increase clarity and usability. There are two different scenarios that will be addressed. First, any second section (XXX.2) that contains definitions that apply only within that article will contain parent text as follows:




In a few cases, in the second section (XXX.2) of an Article there are definitions that will apply only in that Article and some that will apply in that Article and throughout the code. New parent text and first level subdivisions are proposed to achieve clarity and usability The combination of these proposed revisions will provide necessary clarity and usability with respect to application of definitions. These actions will also achieve compliance with the NEC Style Manual.

Illumination Syst... ]

.

Host sign . A sign or outline lighting system already installed in the field that is designated for fieldconversion of the illumination system with a retrofit kit.


Luminaires have standardization and are mass produced, while signs are custom made and have distinctly different structural and illumination characteristics, including multi-location corporate signage programs which are dissimilar in size. A retrofit kit to make a field conversion of a signs illumination system is described in Article 100 as a “complete subassembly of parts and devices.” A “complete subassembly” can only be achieved by identifying the sign designated for field conversion, compiling a parts list and providing applicable installation instructions for the installer and the AHJ that corresponds with the “host signs” distinct structural and illumination configuration.

The product safety standard for sign LED retrofit kits is UL 879A; it identifies a sign selected for retrofitting as a “host sign” requiring the sign undergoing field conversion to be identified in the installation instructions. (Italicized words for emphasis by submitter).

The markings required in 600.4(A)(B) and listing labels shall not be required to be visible after installation butshall be permanently applied in a location visible during servicing.

Exception: Where the disconnecting means is not located within sight of a sign or controller, a warning label withthe disconnect location shall be applied on the exterior of the sign, outline lighting system or controller in alocation visible after installation.



ISA_NEC_Input_Exhibit_No._1.pdf ✓


This requirement incorrectly assumes that service/maintenance personnel are the only ones with a “need to know” the location of a disconnect and that all safety markings have equal applicability. A marking identifying the location of a disconnect for a sign that is not within sight of the sign or controller is required in 600.6(A)(2) and 600.(A)(3)(3 Exception). The disconnects' visibility during servicing is for safety of service personnel. [Informational Note 600.6 Exception No.2] However, others such as emergency responders have need to know where the disconnect is to de-energize a sign or outline lighting system and neutralize a potential hazard while suppressing a fire or responding to an other emergency affecting a sign. {e.g. sign structure failure caused by earthquake, tornado, hurricane, civil disorder, etc]

During the 2011 Code cycle, the sign industry brought to the attention of CMP 18 the unnecessary requirement for signs and outline lighting systems to have multiple visible labels on the exterior of signs that ultimately detracted from the appearance, negatively impacting business branding. The result was the addition of a subsection in the 2011 NEC, 600.4 Visibility that addressed visibility requirements for markings. At that time the new visibility rule was applicable to 600.4(A). Subsequently in 2017 a new subsection, 600.4(B) requiring markings for signs with illumination systems that had been field converted with a retrofit kit was added. These new marking requirements are for the safety of service technicians working on a sign modified with a retrofit kit. There is no safety imperative for the markings described in 600.4(B) to be visible to the general public after the sign installation.

This conclusion also harmonizes with the intent for the addition of 600.4(D) to the 2011 NEC. [2010 ROP 18-204 Log #4025 NEC-P18] The only marking visible to the general public that is important to safety is the marking identifying the location of the disconnecting means when it is not mounted on the sign body, sign enclosure, controller or sign pole.

(B) Marking. A disconnecting means for a sign, outline lighting system or controller shall be marked with theidentity of the sign, outline lighting system or controller it controls.

Exception: An externally operable disconnecting means that is mounted on the sign body, sign enclosure, signpole or controller shall not be required to identify the sign or outline lighting system it controls.

Branch circuits that supply signs shall be rated in accordance with 600.5(B)(1) or (B)(2) and shall beconsidered to be continuous loads for the purposes of calculations.

(1) Neon Signs.

Branch circuits that supply neon tubing installations shall not be rated in excess of 30 amperes.

(2) All Other Signs.

Branch circuits that supply all other signs and outline lighting systems shall be rated not to exceed 20 amperes.


Externally operable disconnects in a remote location from the sign, outline lighting system or controller may not be readily associated with the sign, outline lighting system or controller they control. Anecdotal evidence points to situations where a disconnect technically within sight of the sign, (that is not exceeding 50 feet and visible to the service technician) from the sign, would not be recognized or identified as controlling the sign, outline lighting system or controller by anyone other than the service technician.

Sign service and maintenance personnel as well as emergency responders have a need to know what utilization equipment the disconnect(s) is designated for where it is not mounted on the sign, outline lighting system or controller.

The exception excludes externally operable disconnects mounted on a sign, outline lighting system or controller.

...Renumbering/Changing order to 600.6(C) Control Switch Rating is editorial. Marking is relative to disconnects and grouping it with other disconnect rules contributes to section cohesion.

This section was added to allow transformer boxes (enclosures) used to house neon transformers to include primary and secondary conductors. The other portion was to allow conductors for flood lights and other signs to be in the same raceway. This would add confusion to the new disconnect marking requirements.

(2) Enclosures as Pull Boxes.

Signs and transformer enclosures shall be permitted to be used as pull or junction boxes for conductorssupplying other adjacent signs, outline lighting systems, or floodlights that are part of a sign and shall bepermitted to contain both branch and secondary circuit conductors.

Exception No.1. Raceway enclosures containing feeder or branch circuit conductors supplying a panel board ordisconnecting means on a sign, adjacent signs, outline lighting systems or flood lights that are part of a signshall not be permitted to contain both branch and secondary conductors.


The combining of branch circuit conductors or feeders passing through a sign to a disconnecting means or panelboard or any other electrical load presents a safety hazard for sign service personnel. Historically, it has been a common practice to run energized branch circuit conductors through sign raceways to a disconnecting means or other electrical loads associated with the sign. Wiring rules for signs in 600 do not preclude the combing of energized branch circuit conductors in sign enclosure raceways as stated in 600.5(C)(2). Fabricated raceways that function as enclosures for power supplies and transformers are common to channel letter signs. Channel letters may be attached to enclosures that function as raceways to make a complete sign or section sign. In other installations the enclosures may be mounted in back of a wall as part of a section sign and feed illumination systems in channel letter mounted on the face of a wall. The listed enclosures are rated for damp, dry and wet locations and contain exposed branch circuit and secondary conductors as permitted by 600.5(C)(2) and the product safety standard UL 48.

Where the disconnecting means for the branch circuit or feeder conductors is not located at the point of entry into the enclosure "raceway” or “deck cabinet,” feeder conductors passing through the enclosure are required to be enclosed in a Chapter 3 listed raceway or metal jacketed cable in accordance with 600(A)(1) Exception No.1. This restriction is not feasible for wiring associated with listed enclosure rated “raceways” or “deck cabinets” because the supply circuit wiring to each transformer(s) or power supply(s) would then be required to be in a separate Chapter 3 raceway with appropriate fittings for connection to each power source. The intent for this exception is to clarify that feeder and branch circuit conductors passing through a sign to a panelboard, disconnecting mans or other electrical load are not permitted to be grouped with secondary conductors in the sign.

Exception No . 2 2 : A disconnect shall not be required at the point of entry to a sign enclosure or signbody for branch circuit(s) or feeder conductor(s) that supply an internal panelboard(s) in a sign enclosure orsign body. The conductors shall be enclosed in a Chapter 3 Chapter 3 listed raceway or metal-jacketedcable identified for the location . A field and terminate in the panel board(s). Field -applied permanentwarning label labels that is are visible during servicing servicing shall be applied to the raceway in theworkspace and at or near the exterior point of entry into the sign enclosure or sign body or sign pole . Thewarning label shall comply with 110.21(B) and state the following: “Danger. This raceway contains energizedconductors.” ” The marking shall include the location of the disconnecting means for the energizedconductor(s) conductors . The disconnecting means shall be capable of being locked in the open position inaccordance with 110.25 .





Conductors supplying a sign are required to terminate within the sign as stated in 600.5(C)(1). Exception 600.6(A)(1) is specific to live conductors feeding panelboards. A feeder or branch circuit conductor point of entry to the sign enclosure or sign body may be remote from where the service technician is accessing the sign body or enclosure to the panelboard work space inside the sign. For the safety of the work-person, the warning label should be readily visible in the work space and not confined to the point of entry. The location of the disconnect for the live feeders or circuit conductors is important for the safety of the service technician. Likewise, a visible marking on the exterior with the location of the disconnecting means for the live feeders or circuit conductors is essential to emergency responders in an emergency.

Public Input No. 3740-NFPA 70-2017 [ New Section after 600.6(A)(1) ]

Exception No. 3:

A disconnect shall not be required at the point of entry to a sign body, sign enclosure, or pole for branch circuitconductor(s). The conductor(s) shall be enclosed in a Chapter 3 listed raceway or metal-jacketed cableidentified for the location. The conductor(s) shall be routed to a general-use switch or toggle switch that iscovered by a device box mounted to the sign enclosure or sign body with the switch handle protruding throughthe sign enclosure filler or sign body filler. A field-applied permanent warning label that is visible during servicingshall be applied to the raceway at or near the point of entry into the sign enclosure or sign body. The warninglabel shall comply with 110.21(B) and state the following: “Danger. This raceway contains energizedconductors.” The marking shall include the location of the disconnecting means for the energized conductor(s).This disconnecting means shall be capable of being locked in the open position in accordance with 110.25.


Since creation of 600.6(A)(1) in the 2014 Code cycle, there has been confusion on application of the requirement to disconnect conductors at the point of entry to the sign enclosure or sign body by manufacturers, service personnel, and the AHJ. It has required installing a disconnecting means inside a suitable enclosure for the location (general-use switch or toggle switch mounted to a cover on a bell box is common) and securing it to a customer's sign which was designed to be aesthetically pleasing and convey the adverting intent desired by the customer.

The informational note added to the 2017 code article 600.6 explains that the location of the disconnect for a sign is intended for service or maintenance personnel to have complete and local control while working on a sign.

600.6(A)(1) Exception No. 2, does not require a disconnect at the point of entry to a sign if conductors are routed to an internal panel board(s). The majority of signs are not constructed as referenced in First Revision No. 5137-NFPA 70-2015 [ New Section after 600.6(A)(1) ], like the ARIA sign in several sections that has an internal panel board(s). The majority of signs correspond more to the definition of equipment rather than the structures common to the large resort properties. The majority of signs have branch circuit(s) associated with their power requirements.

600.6(A)(2)&(3) allow a disconnect to be within sight of a sign or sign controller which is not near the point of entry to a sign enclosure or sign body. While OSHA and NFPA 70E have specific requirements that no work should be done on energized equipment, the likely scenario for service personnel working on a sign, will be that they will not utilize a disconnecting means that is not available at the sign enclosure or sign body. It is understood that the code does not address aesthetics but explaining to a customer that the code requires a disconnecting means mounted to the outside of their sign is challenging.

The addition of Exception No. 3 will enhance the likelihood that service personnel will utilize it while working on a sign enclosure or sign body thus complying with safety requirements for servicing energized equipment. It will allow manufacturers to build signs in the manner that was utilized for decades by mounting a general-use switch or toggle switch through the filler of a sign enclosure or sign body to be operated from the outside of a sign and then cover the switch on the inside of the sign with a device box which isolates it from other parts of the sign before 600.6(A)(1) became a requirement. It will also require the branch circuit(s) conductors to be routed independent of any other wiring in a Chapter 3 wiring method suitable for the location directly to this device box. It is no less safe than the other methods allowed for a disconnecting means not present on a sign enclosure or sign body. In principle, it should enhance the safety for personnel by allowing this method of compliance to be used and have the disconnect where the service personnel need it. It will also allow the disconnecting means to be at the location of a sign cabinet mounted on a pole that service personnel are working on from a bucket truck above grade. If the disconnecting means is mounted at the bottom of the pole of the sign, it is less likely to be used by a single operator service truck person who has no helper, who will be required to return to the base of the sign pole each time they turn the sign off and on during servicing.

TITLE OF NEW CONTENT

Type your content here ... (A) Disconnect location. The Disconnect location for a free-standingsign and all building wall signs shall be located in an accessible location outside of the building thatserves power to the signs.


By requiring a disconnect at the base of a free-standing sign, and/or a disconnect located anywhere on the outside of the building that supplies power to the wall signs, complete safety could be provided to all service personnel when working on the sign sections. We all know that most sign work is done after business hours, with no access to the now allowed lockable sign disconnect that is located within a locked building. The disconnect would not have to be readily accessible, as ladders are no problem and could be lockable from casual disconnection. I have posed this question to my Sign Specialist Classes within the State of Michigan for the last 20 years, and without fail, each student says, "We work 'em hot on the weekends", complete the work, and head home! I am sure that the committee can do a much better job at placing the material in the perfect part of 600.6, if I have missed the mark on placement. Hello Jeff and Mark,

600.30 Applicability.

Part II of this article shall apply to all of the following:

(1) Field-installed skeleton tubing

(2) Field-installed secondary circuits

(3) Outline lighting

(4) Field-installed Retrofit Kits

These requirements shall be in addition to the requirements of Part I.


The Code didn’t include rules for retrofitting signs with retrofit kits when first defined in the 2014 NEC Article 100. Wiring rules for retrofit kits logically fit in Part II of 600 because retrofit kits feature field wiring described in 600.33. A new section 600.35 is proposed for this specialized field wiring activity to make the retrofit kit definition actionable.

(C) Protection Against Physical Damage.

Where subject to physical damage, the conductors shall be protected and installed in accordancewith 300.4 and 600 .33(C)(1):


What constitutes physical damage is subjective. It is usually associated with movement of the conductor, over sharp edges on the connected part and abrasion on the conductor insulation caused by the building wall texture during installation. Enclosing the conductor cable in a listed raceway, which includes listed bushings specifically design for the application or other listed raceways, such as metallic or non-metallic conduit shields the cable from exposure to unseen abrasion during and after installation.

600.35 Retrofit Kits.

A retrofit kit for a sign or outline lighting system shall include Class 2 power supplies or transformers, the LEDs,the LED mounting means, associated equipment including fittings, devices, suitably rated Class 2 power limitedcable, and installation instructions required for field conversion of a host sign.

(1) Installation. The retrofit kit shall be installed in the host sign identified in the installation instructions.

(A) Wiring methods shall be in accordance with 600.12(C)(1)(2), 600.24 and 600.33. Connections to theequipment grounding conductor shall be in maintained in accordance with 600.7(A)(3)

(B) All parts that are not replaced by a retrofit kit shall be inspected for damage and parts damaged duringconversion of the sign shall be replaced or repaired to maintain the sign or outline lighting systems dry, dampor wet location rating.

(C) Field conversion workmanship shall be in accordance with 600.33(B)(10(2) and 110.12





600.35 The Code definition for a retrofit kit is: “A general term for a complete subassembly of parts and devices for field conversion of utilization equipment.” By itself the definition is not a Code requirement. (NEC Style Manual). The Code definition authored by sign industry representatives, which CMP 18 determined encompassed conversions of all utilization equipment with retrofit kits, was intended to address a safety deficiency that is prevalent with sign retrofit kits that do not contain all the parts and devices required for a typically safe field conversion of a designated “host sign” to LEDs. Complete is defined in the Merriam Webster’s Dictionary as ‘having all the necessary parts” and according to the 2004 NFPA Style Manual, 3.1.2, terms not contained in 100 are to be “defined using their ordinarily accepted meanings within the context in which they are used.”

The term “complete” in the general retrofit kit definition has been deemed subjective notwithstanding the norms advanced in the NFPA Style Manual. Code rules in new 600.35 will provide the impetus for implementation of the 100 Retrofit Kit Definition’s intent as applied to signs and outline lighting retrofit kits, to wit: each listed kit is mandated to include “all the necessary parts” for field conversion of a host sign. Qualified electrical testing laboratories (QETL) that certify signs have proprietary protocols for certifying retrofit kits. Code rules are not written to the benefit of one qualified electrical testing laboratory over the other.

Each QETL certifies to the same Product Safety Standard, UL879A Standard for Safety LED Sign and Sign Retrofit Kits (8/16/2016). The 2014 retrofit kit Code definition has been incorporated in the UL Standard glossary but the description of a sign retrofit kit is limited to primary components of the kit that includes: the power supply or transformer, power supply or transformer enclosure, the LEDs, the LED mounting means and installation instructions. Empirical data, based on sign conversion experience dating from 2009 has established that limiting a listed kit to primary components does not include all the necessary parts for a sign conversion. This was the genesis for the 2014 Code definition. Inclusion of new 600.35 seeks to remedy this safety deficiency by identifying what types of “parts and devices” are typically required for field conversion of a sign to LEDs. (ISA Exhibit No. 2)


1 of 2 10/4/2017, 11:31 PM

(1) Signs are custom built in multiple types, sizes and structural shapes. What makes up a “complete subassembly of parts and devices” is based on the host signs structural configuration and in-place illumination system. The installation instructions for field conversion are identifiable for use in the host sign. This Code requirement harmonizes with 879A Standard For Safety, LED Sign and Sign Retrofit Kits, 26.2 (a)(b)(c) and Table 26.1(B Marking). It enables the installer to identify the correct replacement parts and devices needed for a safe conversion. It also facilitates the AHJ’s approval process.

(A) All the rules for Class 2 field wiring in 600 Part II are applicable to LED retrofit kit installations

(B) It is critical that the conversion maintains the electrical safety profile of the sign. Any holes created during the removal of power supplies, transformers or raceways need to be sealed. Bonding of the sign to the electrical grounding conductor must be maintained as well as placing conductors in raceways and replacement of raceway covers where required .

(C) Retrofitting is carried out in the field, largely without field evaluation by a FEB. Code and standards compliance is totally reliant on the workmanship of the installer’s executing the installation instructions for the host sign’s conversion.

605.8 (A)

Freestanding office furniture wiring configurations shall be standardized as 3 circuit, 8 wire systems.The 3 circuit, 8 wire system shall have 3 phase conductors, 3 neutral conductors, and 2 groundingconductors. A 3 pole circuit breaker shall be utilized when the conductors originate from the samepanelboad.


There are a variety of wiring configurations available for freestanding office furniture systems. The field installer is forced to try to adapt the circuit conductors from the panelboard to a variety of wiring configurations. Standardizing on a 3 circuit, 8 wire system will eliminate confusion in the field. There is also confusion regarding the multipole overcurrent circuit breaker requirement. This would be alleviated by this code change. Also, field inspectors are unsure of what the correct wiring configuration should be. Standardizing on a configuration would eliminate this confusion. Additionally, the energy code has an impact on switching of receptacle.
