What Do Electrical Wire Color Codes Mean? Black electrical wire is used for power in all circuits. Any circuit's black wire should be considered hot or live. Black wire is never used for a ground or neutral wire and should be used as the power feed for a switch or an outlet. A black wire is often used in a circuit as a switch leg, the connection that runs from the switch to the electrical load.

Wiring Color Codes Wiring for AC and DC power distribution branch circuits are color coded for identification of individual wires. In some jurisdictions all wire colors are specified in legal documents. In other jurisdictions, only a few conductor colors are so codified. In that case, local custom dictates the “optional” wire colors. IEC, AC: Most of Europe abides by IEC (International Electrotechnical Commission) wiring color codes for AC branch circuits. These are listed in Table below. The older color codes in the table reflect the previous style which did not account for proper phase rotation. The protective ground wire (listed as green-yellow) is green with yellow stripe. Click to expand infograph. IEC (most of Europe) AC power circuit wiring color codes.

Understanding Electrical Cables and Wires Never overload a wire -- for instance, never wire a 20-amp circuit with 14-gauge wire. Wires coated with insulation that is black, red, or another color are hot wires, carrying power from the service panel to the electrical device. White wires are neutral, meaning they carry power back to the service panel. Green or bare wires are ground wires.
