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. They make it easy to identify immediately which wires are live, neutral, or grounded (avoiding costly mistakes and hazardous accidents). The table below gives a quick snapshot of the most common electrical wire colors you can see at home. Which wire goes where? Does it even matter? The answer is, it absolutely matters. Electrical wiring color codes are a standardized system that tells electricians—and you—the specific job of every wire in the circuit.
