In the United States, the following color codes are typically used for power wires in “branch circuits,” the wiring between the last protective device (such as a circuit breaker) and the load (such as a tool or appliance). Requirements that apply only to electronic equipment are so identified. In the USA, color codes are usually utilized for power wires in “branch circuits,” the wiring between the last protective device like a circuit breaker and the load (like an appliance).
