Typical Specification - Page 1 of 2

GeneralThe secondary bus enclosure with current transformers

shall be 600 volt class, suitable for use on systems that do not exceed 600 volts to ground (nor 1000 volts phase-to-phase). Each phase bus shall be designed for and include (or accept) a 600 volt class current transformer (ABB SCL, ABB SCM, GE JAD-0C or equal). The phase bus(es) and the full-size neutral bus shall be constructed for connection to the electrical system with two-hole and/or four-hole NEMA standard bolt-on cable-terminal lugs (terminal lugs shall be supplied by the user). Tamper resistance shall meet the Enclosure Security requirements of IEEE Standard C57.12.28 (Pad-Mounted Equipment—Enclosure Integrity) to resist unauthorized entry, protect authorized and unauthorized persons, and provide positive safety features when installed in areas accessible to the general public. The enclosure shall be constructed for outdoor installation in areas subject to heavy precipitation and in areas of windblown contamination. The equipment shall be completely assembled prior to shipment.

Enclosure ConstructionThe enclosure shall be tamper-resistant, all-welded

construction utilizing 11-gauge minimum sheet steel. Corner plates and braces shall be used as necessary to assure rigidity. The enclosure top shall be cross-kinked to provide watershed and rigidity. The enclosure shall be open bottom with a 1-inch flange inside, all around. The door(s) shall be furnished with a stainless steel door holder that will latch the door open 100 degrees and 140 degrees and resist accidental closing. Door(s) shall be provided with provisions for padlocking and a recessed hex-head (or penta-head) security bolt to prevent unauthorized entry (coordinated to prevent installation of the padlock until the security bolt is tightened when closing the door(s) and to prevent a wrench from operating the security bolt until the padlock is removed when opening the door(s)). The security bolt shall be made captive with a stainless steel washer compressed to an oval shape to severely discourage removal. Hinges shall be stainless steel (with stainless steel pins not less than 0.3125-inch diameter) and shall be welded to both the enclosure and the door(s) to maintain door alignment for the life of the equipment. The enclosure shall be nonventilated to minimize the entrance of airborne contamination, insects, rodents or reptiles. The protective finish shall include necessary grinding, cleaning and phosphatizing, two-component rust-inhibiting epoxy primer and a Pad-Mount Green two-component polyurethane top coat finish (Munsell color 7GY 3.29/1.5). The primer and top coat shall be electronically monitored during application to insure proper ratio and mixing of each component. Total average thickness of paint (after curing) shall be not less than 5 mils. The protective coating shall meet the Enclosure Coating System requirements of IEEE Standard C57.12.28 (Pad-Mounted Equipment—Enclosure Integrity). Removable lift provisions, adequate to withstand handling with normal utility equipment, shall be provided on the outside of

the enclosure. Threaded openings for lift provision bolts shall be blind holes to prevent the entrance of wire or other foreign objects into the enclosure when lift provisions are removed.

Bus and Bus MountingsBus shall be aluminum (Alternate #1—bare copper,

Alternate #2—tin-plated copper) with all burrs and sharp corners removed prior to installation. It shall be punched with 0.5625-inch diameter holes on 1.75-inch centers to accommodate both two-hole and four-hole NEMA standard cable-terminal lugs. The bus shall be constructed to allow installation and provide support for 600 volt class current transformers (ABB SCL, ABB SCM, GE JAD-0C or equal) utilizing the correct number of 0.25-inch by 4-inch primary bars with 10.875-inch outboard centerline mounting holes. The current transformers shall be mounted in a manner that will allow installation or field replacement without the removal of cables that may be bolted to the bus. A minimum of two insulators shall be provided for each bus assembly. The insulators shall be cycloaliphatic epoxy and shall be mounted in a manner that will allow field replacement with standard tools without removal of cables that may be bolted to the bus. Insulators and bus bars shall be installed with stainless steel mounting hardware to provide long life and reduced maintenance. All components shall be arranged to allow visual inspection without de-energizing or removing the equipment from service.

Current TransformersAlternate 1: Current Transformers shall be supplied and

installed by the user.Alternate 2: Current Transformers specified by the user

shall be supplied and installed by the manufacturer.

Voltage TransformersAlternate 1: Voltage Transformers are not required.Alternate 2: When specified, a mounting plate shall be

provided for Voltage Tranformers supplied and installed by the user.

Alternate 3: When specified, a mounting plate shall be provided for Voltage Transformers supplied and installed by the manufacturer.

Secondary WiringAlternate 1: Secondary wiring shall be supplied and

installed by the user.Alternate 2: Secondary wiring shall be #10 THW/XHHW

stranded-copper wire connecting the instrument transformer secondary to the 10-Terminal Test Switch and 13-Terminal Meter Socket installed on the right-hand exterior wall of the Secondary Bus Enclosure (when facing the front door). The secondary wiring shall be color-coded as specified by the user (or the factory color code when the user does not specify a color code).




Bulletin

340-067Page 15 2016

Barrier OptionWhen Option B11 is specified, a clear polycarbonate

barrier not less than 0.25-inch nominal thickness shall be provided (and installed) that divides the utility access compartment from the consumer access compartment. The clearance from the barrier to each wall shall not exceed two inches. The clearance from the barrier to the bottom of the enclosure shall not exceed twelve inches. Openings to accommodate bus bars extending through the barrier shall provide not less than 0.5-inch clearance nor more than 2-inch clearance from the bus bar in every direction.

Grounding ProvisionsFour high-conductivity bronze eyebolt-type ground lugs,

which accept #6 through #2/0 copper conductor, shall be installed on the inside walls of the enclosure (located on each side of each door opening in an accessible position as shown on the drawings).

Accessory EquipmentA corrosion proof nameplate with permanent thermal

transfer printing shall be installed inside one door on the cable compartment. It shall be located at the top corner farthest from the cables when the door is open. The nameplate will provide Type of Equipment, Model Number, Amps Continuous, kV Maximum, BIL, Serial Number, Job Number, Date Manufactured and Weight of Equipment.

When specified, one “Warning - Keep Out! - Hazardous Voltage” sign, Elliott #7201-W2003-316, shall be provided on the outside of each door.

When specified, four anchor-bolt brackets, Elliott #6102-A81-7 or approved equal, shall be supplied with each secondary bus enclosure to provide a means of clamping the equipment to the concrete pad.

PackagingEach secondary bus enclosure shall be bolted to a

solid-top wood pallet (to prevent the forks of a forklift truck from entering the open bottom of the equipment) to prevent hidden damage. The equipment shall be wrapped with 0.125-inch thick polyethylene foam or other suitable material to minimize damage to the finish during shipment.

DrawingsWhen specified, drawings shall be furnished for each

secondary bus enclosure that include:1) enclosure dimensions and location of components.2) proposed cable-training layout and dimensions.3) proposed pad dimensions and location of anchor

bolts.
