2018 VA Electrical Specs.pdf

2018 VA Electrical Specs:

All wire to be stranded conductor unless it is equipment grounding conductor of #10 and smaller.

No more than 3 branch circuits per conduit.

#10 Wire on lengths greater than 100’ and no more than 150’ for a 20 amp branch circuit.

Minimum size conduit is ¾”

Electrical enclosures must be supported individually

All exterior metallic hardware and equipment must be corrosive resistant.

NFPA 70, 70E, 72, 99, 101, 110 and 13 must comply.

Conduits must be supported within 3’ but not closer than 1’of every Junction Box and/or enclosure and within 12” of any 90 degree turn.

Metallic Warning Tape must be used in trenches and within 6” of top of finish grade.

Conduits or raceways through which moisture may contact energized live parts shall be sealed or plugged at either or both ends.

Light standards must be rubbed so there is no indication of “spiral marks” in the concrete. They must have a 45 degree chamfered edge. Grounding conductor at each light pole to be in a separate conduit.

Each light standard must have a 1” spare conduit extending 3’beyond the standard and identified on the As Builts.

Exterior light poles must contain individual inline fuses at the handhole. Molded inline fuses capable of more than one phase conductor is not acceptable.

Compression Fittings must be used and wrench tight.

Conduits must be labeled with circuit identification at points where they enter junction box and/or enclosure. Fire Alarm Conduits must be painted red.

Workmanship as per code will be enforced up to VA Electrical Supervisor expectations.

All three phases motors used on the 208 volt system must be rated at 200 volt specific motors.

All receptacles within 6’ 1”of a sink basin will be GFCI protected unless a specific piece of equipment is being installed, then a single receptacle for the equipment will be installed. All receptacles in service rooms, wet locations, or any room that is partially or entirely below grade must be GFCI protected. All receptacles must be labeled as such.

EVERYTHING that controls, consumes, or is capable of consuming electric will have a label. Label must have circuit identification, panel it is fed from, and where the panel is located.

Receptacles will be installed with ground down.

“POD FURNITURE” will have a connection with a cord end. “POD FURNITURE” must be at least 18” away from the wall to obtain access. Suggest ordering ‘PODs’ without electric, use wall receptacles with surge protectors

Neutral Conductor must be identified with corresponding phase conductor in all junction boxes and/or enclosures. Do not share neutral conductor.

MC Cable must not be used to connect devices horizontally through the wall, separate drops from the ceiling is acceptable to devices in the wall.

Raceway and Cable supports must be UL listed to support raceways.

Phase Colors as follows: (Black, red, and blue for 120/208 volts and brown, orange, and yellow for 277/408 volts.) Neutral conductors shall be white in color for 120/208 volts and grey in color for 277/480 volts.

Panel schedules shall be installed in new panels identifying all circuit breakers and also include the identification of existing circuits. Panel schedules must be installed within two weeks of job completion or as soon as power is applied to an area that is occupied. A copy of all panel schedules will be issued to the Electric Shop.

Wirenuts and splices are not allowed in any electrical panel.

All fire doors must be tied into the fire alarm system with all utilities considered, ie Security / Door openers/ AWE compliant.

Décora Switches shall be used in all corridor areas or heavy traffic areas.

Fire Alarm Specs:

NO Splices

Contact Electrical Supervisor or Fire Alarm Technician before fire alarm system and all components attached is connected to, disconnected from, extended, or interrupted.

A review with fire alarm technician and/or supervisor of work to be performed on the fire alarm system prior to work beginning.

Conduit size 1” and painted red.

Super Duct Detector with test key switch installed at 5’

All wiring must be terminated in terminal cabinet for each floor.

Booster Panel installed on each floor it is powering.
