What’s a GFCI and Why Does It Keep Tripping?

If you’ve ever seen an outlet with “Test” and “Reset” buttons on it — especially in your bathroom or kitchen — you’ve found a GFCI outlet. These little devices are small but mighty when it comes to protecting your home and your safety.

Let’s break down what a GFCI is, what it does, and why it might be tripping (breaking) more than you’d like.

 What Is a GFCI Outlet?

GFCI stands for Ground Fault Circuit Interrupter. It’s a safety device that automatically shuts off power if it detects a dangerous imbalance in the flow of electricity — like electricity leaking through water or a person.

Example:

If you’re using a hairdryer near the sink and water splashes into it, the GFCI cuts the power in milliseconds to prevent a shock. It’s like a fast-acting life-saving switch.

Where Are GFCIs Required?

GFCI outlets are required by code in areas where water and electricity could mix:

• Bathrooms
• Kitchens
• Garages
• Basements
• Laundry rooms
• Outdoor outlets
• Utility sinks

Why Does My GFCI Keep Tripping?

If your GFCI keeps shutting off (aka "tripping"), here are some common reasons:

1. Moisture or Water Exposure

Outlets near sinks, tubs, or outside can trip due to moisture. Even high humidity can trigger it.

Fix: Dry the outlet area or use weatherproof covers outdoors.

2. Faulty Appliance

Sometimes it’s not the outlet — it’s what’s plugged into it. A damaged toaster, hairdryer, or power tool can cause the GFCI to trip.

Fix: Unplug the device and try resetting the outlet. If it stops tripping, the appliance may be the problem.

3. Wiring Issues

Loose connections or damaged wires behind the outlet or in the circuit can trip a GFCI.

Fix: Call a licensed electrician to inspect and repair any wiring problems.

4. Overloaded Circuit

Plugging in too many high-power appliances can overload the circuit, especially in older homes.

Fix: Reduce the number of devices used at once or spread them across different outlets.

5. Defective GFCI Outlet

Like any device, GFCIs can wear out over time — especially if they’re tripping often.

Fix: If the outlet is 10+ years old or won’t reset, it’s probably time for a replacement.

How to Reset a GFCI Outlet

1. Press the “Reset” button on the outlet.
2. If it trips again right away — unplug everything and try again.
3. Still no luck? You may need a pro to diagnose the issue.

 Final Word: Don’t Ignore a GFCI That Keeps Tripping

A GFCI that keeps shutting off is trying to protect you. Ignoring it or constantly resetting it without fixing the root cause can be dangerous.
