1. Colors for 208/120-V Circuits: a. Phase A: Black b. Phase B: Red c. Phase C: Blue d. Neutral: White 2. Colors for 480/277-V Circuits: a. Phase A: Brown b. Phase B: Orange c. Phase C: Yellow d. Neutral: Gray 3. Color for Equipment Grounding: Green 4. Field-Applied, Color-Coding Conductor Tape: Apply in half-lapped turns for a minimum distance of 6 inches from terminal points and in boxes where splices or taps are made. Apply last two turns of tape with no tension to prevent possible unwinding. Locate bands to avoid obscuring factory cable markings. Power-Circuit Conductor Identification, More than 600 V: For conductors in pull and junction boxes, handholes, manholes, and vaults as applicable, use color-coding to identify the phase. Color shall be factory applied to conductor insulation or field applied for sizes No. 4 AWG and larger, if authorities having jurisdiction permit. These colors apply for factory-assembled cables as well as for individual insulated conductors. Colors for nominal 12,500/7,200-V Circuits: 1. Phase A: Brown 2. Phase B: Orange 3. Phase C: Yellow 4. Neutral: Gray
