If an electrical fire were to occur, you should pull out the associated _________.

• A. fuse
• B. circuit breaker
• C. panel connector
• D. breaker

Answer: (D)

When an electrical fire occurs, you isolate the affected circuit by pulling the circuit breaker. This action physically disconnects that circuit from the electrical bus, stopping current flow to the fault and helping prevent the fire from spreading or reigniting. The breaker is the appropriate device to use because it’s designed for quick manual disconnection in an emergency.

Fuses don’t best serve this immediate isolation in flight operations—the protection they provide depends on melting, and replacing components isn’t a rapid, on-the-spot fix. A panel connector isn’t a protective device for fire control. The shorthand term for the protective device you pull is breaker, which is why that option is the correct choice.
