Question

Quizplus · Accepted Answer

The rating of a branch circuit is determined by the rating of the overcurrent device, which is usually a circuit breaker or fuse. The wire size, length of the circuit, and number of receptacles are important factors to consider when designing a branch circuit, but they do not determine the rating of the circuit.
