What Is a GFCI and Why Is It in Your Garage?
A Ground Fault Circuit Interrupter (GFCI) detects tiny current imbalances (as small as 5 milliamps) that indicate electricity is finding an unintended path — often through a person or water. Florida building code requires GFCI protection in all garages, bathrooms, kitchens, and outdoor areas.
Top 5 Reasons Your Garage GFCI Keeps Tripping
1. Moisture and Humidity
Florida's humidity is relentless. Moisture can enter outlets, tools, and extension cords, creating a ground fault. Check for water intrusion near the outlet.
2. Faulty Appliance
Plug your appliances in one at a time. If the GFCI trips when you plug in a specific tool or appliance, that device has an internal fault.
3. Wiring Fault on the Circuit
If the GFCI trips with nothing plugged in, the fault is in the wiring itself — not your appliances. This requires professional diagnosis.
4. Failing GFCI Device
GFCI outlets have a lifespan of approximately 10-15 years. In Florida's heat and humidity, they can fail sooner. A nuisance-tripping GFCI may simply need replacement.
5. Shared Circuit with Outdoor Outlets
Many garage GFCIs protect outdoor outlets as well. If an outdoor outlet has moisture intrusion, it will trip the garage GFCI.
GFCI Troubleshooting Steps
- Press RESET — if it holds, the fault was temporary (likely moisture)
- Unplug all devices and reset — if it holds, test appliances one by one
- If it trips with nothing plugged in — call Ocean Wire Electric
- If it trips immediately after reset — call Ocean Wire Electric
