How many times should you reset a tripped circuit breaker?

• A. Never
• B. Only once
• C. Every flight
• D. Whenever it trips

Answer: (B)

Circuit breakers protect wiring by interrupting current when a fault is detected. If a breaker trips, you’re dealing with a fault that needs investigation rather than a simple power-recall. Resetting it briefly can clear a transient condition, but repeatedly cycling the breaker can allow a continuing fault to overheat wiring or components or mask a problem that could cause a fire. Therefore, reset it only once to test if the condition was temporary; if it trips again, leave it open and address the fault before continuing. This keeps the system safe and helps you plan for proper inspection or maintenance after landing.
