Double Pole Breaker Symbol. This symbol represents circuit breaker with three poles. Unlike a fuse which operates once and then must be replaced a circuit breaker can be reset either manually or automatically to resume. This switch can be wired up as a reversing switch for a motor.
These breakers can be used to serve two separate 120 volt circuits or they can serve a single 240 volt circuit such as your central ac s circuit. Double pole breakers have two hot wires that are connected by a single neutral wire.
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit its basic function is to interrupt current flow after a fault is detected.
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit its basic function is to interrupt current flow after a fault is detected. Unlike a double pole breaker which serves a single 240 volt circuit a cheater serves two 120 volt circuits. This switch can be wired up as a reversing switch for a motor. Circuit breakers come in several styles including the standard single pole breakers that serve 120 volt household circuits and double pole breakers that take up two slots in a breaker box and serve 240 volt appliances a special kind of circuit breaker is the tandem breaker which is designed to allow two 120 volt circuits to be fit into a single slot in the circuit breaker box.
