GFCI Outlets: What They Are, Where You Need Them, and Why They Trip
GFCI outlets are the ones with the little TEST and RESET buttons. They're one of the most important safety devices in your home — and one of the most common reasons we get a call about "dead outlets." Here's what every Bountiful and Davis County homeowner should know.
What a GFCI Does
A Ground Fault Circuit Interrupter watches the electricity flowing out to whatever is plugged in and the electricity flowing back. If even a tiny amount goes missing — because it's leaking through water, a damaged cord, or a person — the GFCI cuts power almost instantly. That's what prevents a serious shock when a hair dryer falls in a sink or a power tool gets wet outside.
Where GFCI Protection Is Required
The National Electrical Code requires GFCI protection in areas where water and electricity are likely to meet. In homes, that generally includes:
- Bathrooms
- Kitchens (countertop outlets and those near sinks)
- Laundry areas
- Garages and accessory buildings
- Outdoor outlets
- Unfinished basements and crawl spaces
- Near pools, hot tubs, and wet bars
Older homes were often built before these rules applied everywhere. Adding GFCI protection is one of the most affordable safety upgrades you can make — and it's often required when you remodel or sell.
How to Test and Reset a GFCI
- Plug a lamp or nightlight into the outlet and turn it on.
- Press TEST. The light should go off (you may hear a click).
- Press RESET firmly. The light should come back on.
- If the power doesn't cut off, or the outlet won't reset, the GFCI needs to be replaced.
Why a GFCI Keeps Tripping
A GFCI that trips is usually doing its job. The question is what it's reacting to:
- Moisture in an outdoor, garage, or bathroom outlet box
- A faulty appliance, tool, or extension cord plugged in downstream
- Damaged or deteriorating wiring on the circuit
- Too many devices sharing one protected line
- An old GFCI that has worn out and become overly sensitive
Try unplugging everything on that circuit and resetting. If it still trips with nothing connected, or trips again soon after, that's a sign of a wiring issue worth having an electrician check — see our electrical troubleshooting page.
"Dead" Outlets? Look for a Tripped GFCI
One GFCI outlet can protect several regular outlets wired after it. So if a bathroom outlet stops working, the GFCI that controls it might be in a different bathroom, the garage, or outside. Check every GFCI nearby and press RESET before assuming something is broken.
When to Call an Electrician
- A GFCI won't reset or won't trip when tested
- It trips repeatedly with nothing plugged in
- The outlet feels warm, looks scorched, or smells like burning
- Your kitchen, bathroom, garage, or outdoor outlets have no GFCI protection at all

Common GFCI Questions
What does GFCI stand for?
Ground Fault Circuit Interrupter. It's a device that shuts off power in a fraction of a second when it senses current leaking somewhere it shouldn't — like through water or a person.
What's the difference between a GFCI and a regular outlet?
A regular outlet just supplies power. A GFCI outlet constantly compares the current going out and coming back. If they don't match by a tiny amount (about 5 milliamps), it trips. You can spot one by its TEST and RESET buttons.
Why does my GFCI keep tripping?
Common causes are moisture in an outdoor or bathroom outlet, a failing appliance or tool plugged in downstream, worn-out wiring, or an old GFCI that has simply reached the end of its life. If it trips with nothing plugged in, have an electrician look at it.
Why is a whole group of outlets dead?
One GFCI can protect other outlets wired after it. If a GFCI in the garage, bathroom, or outside trips, other outlets on that line go dead too. Look for a tripped GFCI nearby and press RESET.
How often should I test GFCI outlets?
Manufacturers recommend testing monthly. Press TEST — the power should cut off — then press RESET to restore it. If it doesn't cut power, or won't reset, it should be replaced.
Do GFCI outlets wear out?
Yes. GFCIs are electronic and typically last around 10 years, sometimes less in damp or outdoor locations. Newer models self-test, but older ones can fail without you noticing.
Is a GFCI the same as an AFCI?
No. A GFCI protects people from shock. An AFCI (Arc Fault Circuit Interrupter) protects against arcing in wiring that can start fires. Some breakers and outlets combine both.
