Wire color: The neutral wire is blue, and the color of the phase wire (A phase is yellow, B phase is green, and C phase is red) should meet the standard. The wiring color codes are the standard safety language of electricity. They make it easy to identify immediately which wires are live, neutral, or grounded (avoiding costly mistakes and hazardous accidents). This guide describes wiring color codes, international standards, and main rules to keep. The mandatory colors for power wiring in the National Electrical Code (NEC) are Green, Bare, or Green/Yellow (a yellow stripe or band on green) for the protective ground (PG), and White (or alternatively Gray) for the neutral wire. Orange also marks the high‑leg in four‑wire delta circuits. is a dedicated content creator at Nassau National Cable, where she simplifies complex electrical concepts.
