Circuit Breaker

In Plain English

A resettable safety switch in your electrical panel that automatically shuts off power when a circuit is overloaded.

Definition

An automatically operated electrical switch designed to protect a circuit from damage caused by excess current resulting from an overload or short circuit. Unlike fuses, circuit breakers can be reset after tripping. They are rated in amperes and interrupt current when that rating is exceeded.

Example

A 20-amp circuit breaker tripped repeatedly, indicating the circuit was consistently overloaded by the new commercial kitchen equipment.
