If a circuit breaker trips, what should we do?

• A. Reset the CB
• B. Do nothing
• C. Inform the Captain immediately
• D. Notify the passengers

Answer: (C)

When a circuit breaker trips, the priority is to manage an electrical fault safely by involving the person in command. A trip means something in the electrical system has faulted or overheated, and simply resetting the breaker can re-energize the fault, potentially leading to a fire or further damage. The right move is to inform the Captain immediately so proper procedures can be followed, the fault can be assessed, the Quick Reference Handbook consulted, and a decision made about whether to reset or isolate the circuit under the Captain’s direction. Doing nothing can leave a real hazard unaddressed, and resetting without authorization can be dangerous. Passing information to passengers isn’t appropriate unless their safety is directly affected. Alerting the Captain right away ensures the correct risk assessment and next steps.
