🔎 30-Second Summary

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.

Fast Answer: GFCI or AFCI keeps tripping? A ground fault means current is leaking to ground—often from moisture, damaged cord, or faulty appliance. Unplug appliances and reset; if it trips with nothing plugged in, the wiring or outlet may be faulty. See outlets not working, breaker tripping.

What Is a Ground 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.

Common Causes

Troubleshooting Steps

  1. Unplug all appliances on the GFCI circuit. Reset the GFCI.
  2. If it holds, plug in one appliance at a time. The one that trips it is the culprit.
  3. If it trips with nothing plugged in, the wiring or GFCI itself may be faulty.
  4. Check for moisture—dry the area, fix leaks.

GFCI vs AFCI

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.

When to Call a Pro

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.
