SECTION 16C
WIRE AND CABLE
1. QUALITY ASSURANCE
A. All current carrying parts are to be designed to conform to the systems which are to supply the current and with capacities ample to safely carry the maximum full loads of that section in which it is located.
2. MATERIAL
A. All wire and cable shall be of the same name brand and shall be in the original wrapping for each respective project.
B. All conductors shall be copper of 98% conductivity with 600 volt insulation. No aluminum wire will be allowed.
C. Conductor sizes should be specified as AWG up to #4/0 and as circular mils above #4/0.
D. Conductors #10 and smaller should be milled, while #8 and larger should be strand.
E. Conductors should be specified with the appropriate type of insulation for the given conditions of each project and in compliance with NEC regulations.
F. Provide all empty conduits with appropriate pull wire.
3. EXECUTION
A. The minimum size conductor shall be #12 AWG.
B. All lighting and receptacle branch circuit conductors shall be color coded.
C. Feeder cables and service entrance conductors shall be color coded by use of colored plastic tape. This tape shall be applied within six (6) inches of each conductor end. All color coding shall be with the same color being used with its respective phase or bus through the entire job as follows:
120/240 Volts 120/208 Volts 277/480 Volts
Phase A Black Black Brown
Phase B Orange (Hi-Leg) Red Orange
Phase C Blue Blue Violet
Neutral White White Gray
Ground Green Green Green
D. Phase rotation shall be the same in all panels.
E. If the situation arises where two conductors from the same phase occur in the same conduit, an additional neutral must be provided and have a tracer or marking tape.
F. Every wire in a pull box, junction box or equipment wire chamber shall be labeled with the proper panel letter and circuit number identification. Where two or more wires are spliced each shall be labeled. Labels shall be printed numbers and letters on suitable material.
G. At the end of all wires and cables for power, lighting, control and signal, only sufficient slack shall be left as may be needed for making proper connections. There should be no unnecessary slack.
H. All wires and cables for power, lighting, control and signal shall be continuous from origin to destination with the use of proper devices to splice. Wire nuts shall be acceptable for wires #8 and smaller.
I. The Project Engineer shall ensure the Contract Documents address the care of pulling cables, specifically the maximum pulling tensions allowed on cables to avoid damage.
