2.3 SOLID AND STRANDED<br />

A. General Requirements:<br />

2.4 INSULATION<br />

1. Wires shall be solid or stranded for sizes 10 AWG and smaller.<br />

2. Wires shall be stranded for sizes 8 AWG and larger.<br />

A. Voltage Class: Insulation, unless otherwise noted, shall be 600 volt.<br />

B. Insulation Type: Conductor insulation shall be as follows:<br />

1. Service, Feeder, and Branch Circuit Conductors: Type THHN/THWN with a<br />

temperature rating of 75 degrees C.<br />

C. Color Code: Wire and cable color shall be in accordance with the latest edition of the<br />

NEC. On larger cables, where factory color coding is not available, marking tape shall be<br />

used to identify each phase and neutral conductors. A minimum length of six inches shall<br />

be color coded at each end and in all pull boxes. For modifications and additions to<br />

existing wiring systems, color coding shall match existing wiring systems.<br />

2.5 CONNECTORS AND TERMINATIONS<br />

A. Conductors 8 AWG and Smaller: Use solderless crimp or indent type pressure<br />

connectors with insulating covers for copper wire splices and taps for 8 AWG. For 10<br />

AWG and smaller, use insulated spring wire connectors with plastic caps. Strictly comply<br />

with the number, size and combination of conductors as listed on manufacturer’s<br />

packaging.<br />

B. Conductors 6 AWG and Larger: Use split bolt connectors for copper wire splices and<br />

taps, 6 AWG and larger. Tape uninsulated conductors and connectors with electrical<br />

tape.<br />

2.6 CONTROL WIRING<br />

A. General Requirements:<br />

1. Control conductors shall be 14 AWG or larger, if provided under this division<br />

Wiring provided under Division 15, shall be #18 AWG or larger.<br />

2. Conductors shall be sized large enough so that voltage drop under in-rush<br />

conditions will not adversely affect operation of the controls.<br />
