A 50-amp breaker can run appliances like ovens, hairdryers, air conditioners, and multiple lights simultaneously while (possibly) still sparing power. The reason for this breaker’s capacity is because it can hold up to 12,000 watts running on a 240-volt circuit (50-amps x 240-volts).

Can I use double pole breaker for 120V?

Double-pole breakers have two hot wires that are connected by a single neutral wire. That means if there’s a short circuit on either of the poles’ hot wires, both trip.
