Question

Quizplus · Accepted Answer

A 120-volt branch circuit typically requires a single-pole circuit breaker to provide the necessary protection. Double-pole or three-pole breakers are used for 240-volt circuits or multi-phase circuits, which is not the case here. HACR (Heating, Air Conditioning, and Refrigeration) type circuit breakers are specific to those applications and not directly related to the voltage or pole requirement of a circuit for a dishwasher.
