Circuit Breaker

An electrical overload protection device in the aircraft electrical system that automatically disconnects (pops out) when current exceeds the rated limit for that circuit, preventing wiring damage or fire. Unlike fuses, circuit breakers can be reset by pushing them back in. If a circuit breaker trips, the pilot should identify the associated system, assess the situation, and attempt one reset. If it trips again, it should not be reset, as this indicates an ongoing fault. Circuit breaker panels in the cockpit allow the pilot to identify and isolate specific electrical failures.
