SAFE NEXT CHECKUnplug everything on the circuit, reset, then reintroduce devices one at a time until the one that trips it is found.
Where to stop. Resetting and plug-in testing are homeowner-safe. Opening the box, checking terminals, or rewiring line/load means live conductors — if you cannot do that safely with the power off at the breaker, stop and call a licensed electrician. Water plus electricity is a shock hazard; do not keep resetting a wet outlet. This is general information, not a quote and not a substitute for a licensed electrician.
CURRENT IMBALANCE hot ≠ neutral → leak to ground → trip hot neutral leakage to ground
