Receptacle Classifications

There are three separate testing standards—independent of one another.

UL is the most common standard of testing, and it is important to specify receptacles and

switches that are UL compliant.

Some manufacturers take an extra measure and put their devices through Fed Spec

testing, which means the products are put through a separate, more rigorous testing

standard. In the chart on the following slide, some of the tests that are not performed withUL but are performed through Fed Spec are highlighted in red.

Hospital grade testing is performed by UL and consists of specific testing standards that

ensure a redundant ground in very rigorous situations. All of the tests are to ensure safety

measures, but hospital grade testing is performed in addition to UL or Fed Spec.

With all the device “grades” available, choice is important. Write your Master Spec around

the specific key features and quality you want, then hold to it.

Duplex Receptacles










8/16/2019 LE-EN-55705-0816




Features To Look For










8/16/2019 LE-EN-55705-0816





• One-piece, brass wrap-around strap

• locking “fingers” into the device back

body and face

• integral ground contacts

The one-piece, brass wrap-around strap provides

strength and better conductivity in a “uniground”

assembly.

• Drive screws in addition to the locking fingers

that lock the strap into device face and body

This prevents the strap from separating from the

face and back body and exposing live parts.










8/16/2019 LE-EN-55705-0816





• Self-grounding device mounting screw

Self-grounding mounting screws ensure a solid

connection to ground without needing to install agrounding jumper to the box from the device in the

absence of a grounding conductor.

• Tri-drive head terminal and ground terminal

screws

Tri-drive head terminal screws accept Robertson,

Phillips, and standard straight blade screwdrivers—this facilitates a better termination.










8/16/2019 LE-EN-55705-0816





• Back-wired terminal clamps via external screw

pressure-plate

Back-wired terminal clamps allow for visualindication that all strands of wire are correctly

secured and that there is a good connection.

• One-piece, triple-wipe internal brass power

contacts

Triple-wipe contacts provide plug holding strength

and superior electrical connection.










8/16/2019 LE-EN-55705-0816




Special Requirements: Tamper-Resistant

• Tamper-Resistant

Child safety presents a major concern for electrical manufacturers, and Tamper-Resistant

receptacles have long been considered the most reliable means of protection. The 2014NEC Code continues to add and revise current standards that include, but are not limited

to, all 15- and 20-amp, 125-volt receptacles to be placed in all pediatric care areas,

dwelling locations, childcare facilities, guest rooms, guest suites, etc. Some of these Codes

have section revisions to accommodate exception changes.

A mechanical shutter that will not open unless a proper plug is used:

Thermoplastic shutter in

closed position covers access

to contacts.

Insertion of object in any one

side does not open shutter.

Two-bladed plug or grounding

plug compresses spring and

simultaneously opens bothshutters.










8/16/2019 LE-EN-55705-0816





• 2005 NEC Section 517.18 (c): TR receptacles required in all pediatric care areas.

• 2008 NEC Section 406.11: TR receptacles required in all dwelling locations.

• 2011 NEC Section 404.4 (D)(5): TR receptacles required to be installed wherever areceptacle is replaced in areas that are required to be TR by code.

• 2011 NEC Section 406.12, 13 & 14: TR receptacles required in childcare facilities,

guest rooms, guest suites, and specified dwelling areas.

Tamper-Resistant receptacles have been required in pediatric care areas for years. The

importance of TR receptacles came about with the NEC Code in 2005, where TR

receptacles became a requirement in all pediatric care areas. It was expanded in 2008 with

the requirement to include them in all dwelling locations, including residential housing (that

was modified in 2011 to exclude any receptacle 5½ feet above the floor or higher). In 2011,the requirement was expanded to include childcare facilities, guest room suites, and any

other area identified as a dwelling location.

Special Requirements: Isolated Ground

Providing a separate “clean” ground path to the main service

ground reduces electrical noise (EMI) from being conducted

to sensitive electronic equipment and corrupting data, or

causing malfunctions of critical equipment and life-safetysystems.

Special Requirements: Hospital Grade

• Hospital grade – “green dot”

Receptacle devices must pass several additional UL 498 test

requirements to be listed as hospital grade and bear the greendot on the device face.

Hospital grade devices are required by UL to withstand

significantly higher levels of abuse and the additional life-safety

considerations in healthcare facilities.

Additional UL 498 test requirements include a demonstrated

ability to withstand severe abuse and continue to maintain:

• assembly integrity (no exposed live parts)

• power blade retention (continuity of service when a patient

needs it), and

• grounding pin retention (ensures grounding continuity for

equipment in contact with patients).

• Hospital grade – illuminated face

This is an extended service LED version with an illuminated

face. An LED (light emitting diode) illuminated face generally has10–12 years of life, offering long service and reduced

maintenance.

The benefit is that they are easy to find in darkened rooms of

24/7 healthcare facilities.

They are often installed on emergency, critical care, and life

support circuits to locate receptacles during power outages and

emergency conditions.














8/16/2019 LE-EN-55705-0816





• Hospital grade – write-on label

A write-on label for recording circuit designation is used to

indicate the circuit on which the receptacle is wired, even if theplate is removed, so power to the correct circuit can be easily

shut off.

The plates may be removed for repainting walls, receptacle

replacement, or troubleshooting.














8/16/2019 LE-EN-55705-0816





• Hospital grade – minimum number required

The hospital grade receptacles required by 517.18(B) are

permitted to be of the single, duplex, or quadruplex type orany combination of the three that add up to at least the

minimum of eight receptacles required. In critical care areas

per 517.19(B), each patient bed location should be provided

with a minimum of 14 receptacles. These receptacles shall

be either single, duplex, or quadruplex type, or anycombination of the three. In operating rooms, per 517.19(C),

a minimum of 36 receptacles are required and shall be

single or duplex types, or a combination of both. The

grounding terminals of the hospital grade receptacles must

be connected to an insulated copper equipment-groundingconductor of the branch circuits required by 517.13(B).














8/16/2019 LE-EN-55705-0816




Hospital Grade Receptacles

UL Hospital Grade Testing for Receptacles

• Abrupt Removal Test

– 10 lbs. down by excessive force• Ground Contact / Overstress Test

– 4 oz. minimum retention

• Impact Test

– 5 lbs. weight onto center of device• Assembly Security Test

– 100 lbs. support test

Hospital grade receptacles go through strenuous procedures and testing. The testing isabove and beyond the standard UL and Fed Spec testing. The key point for a hospital

grade receptacle is excessive redundant ground capabilities that offer the highest level of

safety.














8/16/2019 LE-EN-55705-0816





Abrupt Removal Test

After ten conditioning insertion and withdrawal

cycles of an attachment plug of matchingconfiguration and ground pin, each outlet is to

hold, without any displacement, a fully inserted

test pin for at least one minute from a facedown,

horizontal position. Then, each receptacle is

mounted to represent a typical installation andgoes through a series of abrupt removal tests—

the full insertion of a test plug that is removed by

dropping an attached 10-pound weight two feet,

thus exerting excessive force on the receptacle

face and contacts. Each outlet must go througheight cycles of this test. The outlet must have no

breakage that would interfere with its function and

integrity.














8/16/2019 LE-EN-55705-0816



About the Instructor About the Sponsor Ask an Expert


Ground Contact / Overstress Test

The receptacle ground contact is conditioned with

twenty cycles of full insertion and withdrawal of a.204" oversized test pin. Then, with the receptacle

in a horizontal, facedown position, the same

contact must retain a .184" diameter 4-ounce test

pin for at least one minute without any

displacement.














8/16/2019 LE-EN-55705-0816





Impact Test

Receptacles mounted in a cast metal box are

placed on a steel plate facing upward. A 5-poundweight is dropped from 18" above the device

impacting at the center of the outlet. The device

must withstand the impact without having any

breakage that hinders its function.














8/16/2019 LE-EN-55705-0816





Assembly Security Test

A device, supported at its mounting screws, must

withstand 100 pounds through the slots in thereceptacle face without cracking the device back-

body or deforming the yoke.

Hospital Grade Plugs and Connectors

Hospital grade plugs and connectors are tested

to the demanding requirements of UL 498

(similar to hospital grade receptacles).

These requirements cover attachment plugs,

receptacles, cord connectors, inlets, current taps

provided with wiring terminals for flexible cord,

and flatiron and appliance plugs—all intended

for connection to a branch circuit for use inaccordance with the National Electrical Code,

ANSI/NFPA 70.

Specifications for “hospital grade” connectors

appear in UL498-2001, Supplement SD.














8/16/2019 LE-EN-55705-0816

Hospital Grade Testing

Dependable device solutions are required in the most critical health care applications.

• Reliable power quality is required by sensitive equipment, under repetitive abuse.

• Dependable ground continuity of wiring devices protects both personnel and patients

from compromised electrical connections.• Corrosion resistance is a necessary feature where frequent wash downs result in

excess moisture that can compromise performance.

• Replacement of wiring devices must be quick and easy.

Crush Test - A wired plug or connector isplaced between two steel plates andsubjected to a force which is steadilyincreased to 500 pounds. “There shall be nobreakage, deformation or other effect thatmay interfere with the function of the device.”

Drop Test - A sample wired plug or connector issuspended horizontally by its attached cord, andreleased so that it impacts a hard wood surface45 inches below the point of suspension &repeated for 1300 cycles. “There shall be nobreakage, deformation, or other damage whichwould interfere with the functioning of the device.”

Pull Test - The cord must remain securely fastenedafter straight pulls of 30 lbs. and rotating pulls (in a 3-inch circle) of 10 lbs. for two hours. “Displacement ofconductors, insulation, and outer jacket of the flexiblecord shall not exceed 1/32 inch. There shall be nocuts, rips, or tears in cord insulation. “Heavy-dutycord stress is typical abuse for industrial plugs andconnectors.”

Ground Fault Circuit Interrupter (GFCI) Devices














8/16/2019 LE-EN-55705-0816



What Is a GFCI?

The National Electric Code 2005 Edition Article 100 defines a

GFCI:

“A ground fault circuit interrupter (GFCI) is a device intended

for the protection of personnel that functions to de-energize acircuit or portion thereof within an established period of time

when a current to ground exceeds the values established for a

Class A device.”

Class A ground fault circuit interrupters trip when the current toground has a value in the range of 4 mA to 6 mA.

GFCIs protect against electric shock incidents, including death

by electrocution.











8/16/2019 LE-EN-55705-0816



How a GFCI Works

A GFCI has an internal comparator

circuit that monitors the difference in

current between the hot and neutral on

the load side of the device. If thecomparator circuit senses a difference

between the hot and neutral of 5 mAs, it

will interrupt power to the load side of

the receptacle in .025 seconds—

preventing a serious injury due toelectric shock.

Normal

Conditions.

Hazardous

Ground Fault.

GFCI

Protected.











8/16/2019 LE-EN-55705-0816



How a GFCI Works

The diagram shows the dangers of

electrical current. Less than 20 mA will

affect respiration. It only takes 50 mA to

cause heart fibrillation. The GFCI isengineered to trip at about 5 mA, a level

below that which would injure a healthy

person.











8/16/2019 LE-EN-55705-0816



How a GFCI Works

Because a GFCI constantly monitors the hot and neutral conductors only, a ground

conductor is not required for the device to function properly. This allows GFCIs to be used

in retrofit applications in older houses with two-wire (non-grounded) wiring.

Receptacle-type GFCI’s switch both the ungrounded conductor and neutral.











8/16/2019 LE-EN-55705-0816



Electrocution Data

Note the significant electrocution decline represented by the red line. In the mid 1970s time

period, there were more than 600 consumer product related electrocutions annually. Today,

there are less than ⅓ that number, in large part due to GFCI receptacle use.

GFCIs are required by NEC 2011 in facility areas prone to electrical shock such as

kitchens, bathrooms, utility rooms, garages, swimming pools, outdoors, construction sites,

crawl spaces, etc. The NEC continuously updates their codes and adds new locations that

require GFCIs.

UL recommends that installed GFCIs should only be tested with their integral TEST and

RESET buttons.

In addition, UL, NEMA, and OSHA recommend not using external testers because they do

not produce accurate results.

GFCI receptacles manufactured on or after June 29, 2015 will require the self-test (auto-

monitoring) feature.

• GFCI device trip indicator light

The trip indicator light is “on” when the GFCI is

tripped. This provides a visual indication in addition tothe RESET button tripped-out that a ground fault

condition has occurred and may still exist, or damage

to the device may have occurred and protection has

been lost.

The trip indicator light is a convenience feature in

addition to the RESET button tripped-out. The light

makes it easier to identify a tripped GFCI.

In general, when the GFCI is tripped, the light will be

on. When the GFCI is RESET, the light will go off.











8/16/2019 LE-EN-55705-0816




• GFCI device “auto-ground” feature

This is an “auto-ground” feature in the strap that assures grounding when the device is

screwed to the metal box. This feature eliminates the need to run a separate equipment-

grounding wire from the metallic box to the GFCI device.This feature ensures proper equipment ground, which helps to prevent electrocution.

• Self-test GFCI devices

A self-test GFCI conducts an automatic test every second, ensuring that it is always readyto protect.

If the device fails the test, the indicator light flashes to signal that the GFCI should be

replaced.

• Hospital grade GFCI devices (green dot)

GFCI devices must meet the same additional test requirements in UL 498 that a receptacle

device must pass to be listed hospital grade and bear the green dot on the device face.

This ensures the GFCI device helps to prevent injury, including electrocution, in healthcare

facilities.











8/16/2019 LE-EN-55705-0816




• Importance of meeting Fed Spec requirements

Federal Specification W-C-596 – General Specification for Electrical Power Connectors

has long been used as the quality standard for commercial receptacles. The document isproduced by the General Service Administration of the U.S. Federal Government and

identifies construction features, marking specifications and performance requirements

beyond the requirements of the safety standards, for the purpose of durability and service

life. Underwriters Laboratories is authorized to apply the federal specification verification

mark, and Fed Spec is required on many government projects.

W-C-596 requires more rigorous abuse and performance tests in:

• Blade retention• Terminal strength

• Current overload

• Temperature rise

• Integrity of assembly• Grounding contact

• Accelerated aging

• And more…











8/16/2019 LE-EN-55705-0816



Testing GFCI Receptacles

Test during installation and monthly:

1. Plug lamp into GFCI.

2. Turn on lamp.

3. Push TEST button. GFCI should trip, stopping flow of electricity to the lamp.

The RESET button will pop out.

4. If the lamp does not turn off when the test button is pushed, the GFCI is not working

properly and should be replaced immediately.

5. If the lamp does turn off when the test button is pushed, the GFCI is working properly.

To restore power, press the RESET button.








8/16/2019 LE-EN-55705-0816



UL Certification Tests for GFCIs

GFCI receptacle devices must meet these more rigorous, revised UL certification tests for

GFCIs effective July 28, 2006:

End of Life: When a GFCI receptacle is incapable of passing its internal test function (it is

no longer capable of providing ground fault protection), it will comply with either a or b:

a) Render itself incapable of delivering power

b) Indicate by visual and/or audible means that the device must be replaced

Reverse Line-Load Miswire: A GFCI loses its ability to protect when it is miswired (line

wires connected to load terminals and load wires connected to line terminals).

UL requirements to comply with:

a) Yellow warning sticker on load terminals

b) A GFCI will deny power to the receptacle face if it is miswired

GFCI FAQs

Q: Can a GFCI be installed on a two-wire system and will it work

properly?

A: Yes, a GFCI can be installed on a two-wire system, and if a

ground fault should occur, the GFCI will safely remove voltage to the

load. The installation is allowed by the National Electrical Code,

Article 406.4(D)(2)(b). Even in a three-wire system, the GFCI is only

monitoring the hot and the neutral conductors. If a leakage path toground is formed, the path will be between the load and ground or

through the body and ground. At that time, if the leakage is sufficient,

the GFCI will detect the difference between the hot and the neutral

current, and the GFCI will trip.








8/16/2019 LE-EN-55705-0816



GFCI FAQs

Q: How many receptacles can be wired downstream from a GFCI?

A: There is no set limit; however, thought should be given to thelength of the wire run. The farther the distance is from the GFCI to

the load, the greater the chance is for nuisance tripping to occur.

Please remember the exam password TRIPPING. You will be required to enter it in

order to proceed with the online examination.

GFCI FAQs

Q: I just installed a GFCI in a facility. I have two receptacles wired to

be protected downstream. When I push the test button, the unit will

trip. The power is removed on the receptacles downstream, but there

is still power on the GFCI. Is the GFCI defective?

A: No, the GFCI is not defective. This question is also a classic. The

GFCI was wired with the line and load conductors in reverse (line-

load miswire). When the test button is pushed, the unit will trip. Ifreceptacles are wired downstream, voltage will be removed to those

devices and power will remain on the GFCI contacts. It is strongly

recommended upon installation of a GFCI to test for voltage at the

contacts after the GFCI has been tripped.

GFCI FAQs

Q: My GFCI has a NEMA 5-15R configuration, but the side of the

device says it is rated for 20-amps. Do I have the proper unit, or is

the device incorrectly marked?

A: The 15-amp GFCI, just like a receptacle, is designed to be

installed on a 15- or 20-amp branch circuit. The 20-amp rating is for

when the device is used in a feed-thru application on a 20-amp

branch circuit. A 15-amp GFCI and a NEMA 5-15R receptacle aretested by UL to confirm the devices are capable of handling the

higher current.

Arc-Fault Circuit Interrupter (AFCI)

AFCI receptacles protect against electrical fires.

NEC definition of AFCI:

A device intended to provide protection from the effects of arc faults by recognizingcharacteristics unique to arcing and by functioning to de-energize the circuit when an arc

fault is detected.








8/16/2019 LE-EN-55705-0816



AFCI Receptacle: Types of Arcing

Arcing is current flowing

through an unintended

path.

There are two types of

arcing: parallel and series

(between ends of broken

conductor).

Very high temperature are

possible―10,000 degrees

Fahrenheit ignites studs,

and conductor insulation.

AFCI Receptacle: 2014 NEC Requirements

Section 210.12 (A) requires arc-fault circuit interrupter protection in dwelling units,

dormitory units, and on dwelling unit branch-circuits that are extended or modified. The arc-

fault circuit interrupter shall be installed in a readily accessible location.

Dwelling Units – All 120-volt, single phase, 15- and 20-ampere branch circuits supplying

outlets installed in dwelling unit kitchens, family rooms, dining rooms, living rooms, parlors,

libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, laundry areas,

or similar rooms or areas shall be protected by a listed arc-fault circuit interrupter.

Dormitory Units – All 120-volt, single-phase, 15- and 20-ampere branch circuits supplying

outlets installed in dormitory unit bedrooms, living rooms, hallways, closets, and similar

rooms shall be protected by a listed arc-fault circuit interrupter.

Note: Guest Rooms and Guest Suites – Guest rooms and guest

suites that are provided with permanent provisions for cooking shall

have branch circuits installed to meet the rules for dwelling units

(including AFCI protection).

Surge Protective Receptacles

A steady green light means the device is protected. The audible alarm function can either

be enabled (default position—shipped this way) or set to “alarm off,” which must be set

manually.

Once the device can no longer protect against transient surge voltage, the alarm will

sound, and the LED will indicate this by flashing red simultaneously. The alarm can then be

turned off, but the LED will continue to flash red. The device will still allow for power

access, but will no longer protect against transient surge voltage.

The audible alarm will not come on when the LED remains green.

It is possible for the LED to flash red, yet the audible alarm does not come on. This is when

the “alarm off” switch is in the “disabled” position. This LED-only indication still means thatthe “end of life” condition now exists.
