Power Cord Wire Colors



There is a multitude of different power cord wires with varying colors – each one designed to meet a specific safety standard and serve a corresponding purpose. Knowing the meaning behind each power cord wire color can be helpful for identifying the type of device connected to your home electricity supply or for troubleshooting an appliance.

The National Electrical Code requires that electrical supply cords have an insulated grounding conductor. This ground wire is green or bare and protects against shocks or electrical intrusions, adding another layer of safety for everyday use. Black and white are the two most standard wire colors used in homes and typically signify the positive and negative terminals on a circuit. Red and blue wires are also commonly found in household wiring and denote a separate circuit breaker for each wire.

Having an understanding of different power cord wire colors makes it easier to identify which wire runs where and to identify any potential wiring problems. In addition, safety standards require the wires in power cords to be colored so that any malfunctioning appliance or wire can be quickly identified. However, if you’re unsure, it’s best to consult a certified electrician when rewiring or troubleshooting any appliance.
