Wiring Methods and Components - Conductors for General Wiring

Temporary or permanent conductors can create shock and fire hazards that usually can be prevented through insulation. Insulating material should be the appropriate composition and thickness as rated for:

Voltage the conductor will carry

Current the conductor will carry

Temperature extremes and other environmental factors

Location of the conductor.

Insulated conductors must also be easily identifiable, color coding is most often used. The colors to be used are:

White or natural gray for neutral conductors
Green or green with yellow stripes for equipment grounding conductors unless bare wires are used.

Other types of circuit wires may be any color except those listed above.
