Step-by-step instructions
Stop using a repeatedly tripping circuit
A trip is protective; do not keep resetting while an unknown fault remains.
Identify the device that trips
Note whether it is the pedestal breaker, vessel main, branch breaker or ground-fault protector.
Log connected loads
Record AC, water heater, battery charger and other loads operating when it tripped.
Look for visible damage safely
From outside energized panels, inspect shore cord and plugs for heat, charring or water intrusion.
Have faults tested
A qualified marine electrician should evaluate leakage, incorrect wiring, overload and equipment insulation.
Safety note
Shore power can be fatal. Never bypass an ELCI or breaker, use damaged connectors, or test live wiring without training.
Key takeaway
The breaker location and trip pattern help determine whether the problem is an overload or a fault.
