SECTION 260516 - WIRES AND CABLES: continued
3.02 INSTALLATION OF WIRES AND CABLES:
A. General: Install electrical cables, wires, and connectors in compliance with NEC.
B. Coordinate cable installation with other Work.
C. Do not pull wire and cable until raceway system is complete. Pull conductors simultaneously
where more than one is being installed in same raceway. Use UL-listed pulling compound or
lubricant that is compatible with wire outer covering, cable outer covering, raceway, and
wire/cable manufacturer's recommendations.
D. Use pulling means including fish tape, cable, and basket weave wire/cable grips which will not
damage cables or raceways. Do not use rope hitches for pulling attachment to wire or cable.
E. Keep conductor splices to a minimum. All splices shall be made in junction boxes.
F. Install splice and tap connectors which possess equivalent or better mechanical strength and
insulation rating than conductors being spliced.
G. Use splice and tap connectors which are compatible with conductor material.
H. Provide adequate length of conductors within electrical enclosures and neatly train the
conductors to terminal points. Circuits with conductors larger than No. 10 AWG shall be
bundled together inside of enclosures. Make terminations so there are no bare conductors
visible at the terminal.
I. Tighten electrical connectors and terminals, including screws and bolts, in accordance with
manufacturer's published torque tightening values. Where manufacturer's torquing
requirements are not indicated, tighten connectors and terminals to comply with tightening
torques specified in UL 486A.
J. Table 1:
1. Insulation Color Coding for Phase Identification:
2. Color code 600V insulated, service entrance, feeder, and branch circuit conductors with
factory-applied colored insulation for No. 8 AWG and smaller (except No. 6 AWG and
smaller for green ground wire); 1-inch band of colored tape at all splices and terminations
for No. 6 AWG and larger (except No. 4 AWG and larger for green ground wire) as
follows:
208Y/120V 60 hertz Phase 480Y/277V 60 Hertz Vdc
Black A Brown
Red B Orange
Blue C Yellow
White Neutral Gray
Green Ground Green
Positive
Red
Negative
Black
3. Identification tape shall be with 4 inches of termination.
K. Group circuits in conduit such that no conduit contains more than a total of three phase
conductors, three neutral conductors, and one ground conductor (unless indicated or specified
otherwise).
L. Install wire and cable numbers on all field wiring that matches electrical schematics.
M. Leave 12 inches of each wire in each receptacle and wall switch device box.
3.03 FIELD QUALITY CONTROL:
A. Prior to energizing, test wires and cables for electrical continuity and for short circuits.
