Double Pole Circuit Breaker Wiring

Double pole breakers have two hot wires that are connected by a single neutral wire.

Double pole circuit breaker wiring.

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 snap onto two poles for a total of 240 volts. Wiring for a 15 amp 120 volt circuit breaker. Adding a circuit to a service panel is a relatively simple home improvement project.

In addition these heavy duty breakers have two incoming wires rather than the single wire for standard breakers. Circuit wiring that connects to double pole breakers contains two hot wires.
