How many times may a circuit breaker be reset?

• A. Up to three times regardless of safety
• B. As many times as needed until reset happens
• C. Never reset a circuit breaker
• D. Only reset if the PIC determines it is necessary for safety of flight

Answer: (D)

Circuits breakers trip to protect wiring and equipment when a fault or overload occurs. Resetting isn’t a reflex action; it should be done only if the pilot in command determines that restoring power to that circuit is necessary for the safety of flight. This preserves the balance between keeping the aircraft operable and not masking a continuing fault. There isn’t a universal numerical limit to resets, and it isn’t correct to say never reset. The PIC has the authority to reset if doing so supports safe operation, but if the fault recurs or the circuit isn’t essential to flight safety, resetting should be avoided and maintenance should be consulted once on the ground.
