Quizplus · Accepted Answer

A 240-volt electric water heater requires a double-pole circuit breaker in order to appropriately handle the voltage and current needed for the appliance. A single-pole circuit breaker would not be able to handle the load and a three-pole circuit breaker would be unnecessary for the application. HACR is a type of circuit breaker rating but it does not address the number of poles needed for a specific application.
