Ground faults in RVs can cause GFCI outlets to trip due to leakage currents often caused by moisture, damaged cords, or faulty appliances. Proper troubleshooting involves checking appliances, wiring, and moisture presence to identify the source of the fault.

A ground fault occurs when hot wire current flows to ground (or neutral) through an unintended path—e.g., through water, a person, or damaged insulation. GFCI outlets detect this imbalance and trip in milliseconds to prevent shock.
GFCI protects against ground faults (shock risk). AFCI protects against arc faults (fire risk). Some RV panels have AFCI breakers that trip on arcing—e.g., from loose connections or failing motors. See breaker tripping for overload vs fault.
If the GFCI trips repeatedly with nothing plugged in, or you see scorch marks, burning smell, or sparks—shut off power and call an electrician or RV technician.
