What is a load wire?

A load wire is a wire or cable that is used to carry electrical current to a load or device, such as a light, motor, or appliance. The load wire typically connects to one terminal of the load, while the other terminal is connected to a power source. The load wire is usually color-coded to differentiate it from other wires in an electrical system, such as the hot wire and neutral wire. It is important to properly size and install the load wire to ensure safe and efficient operation of the electrical system.
