Where GFCIs belong, and why they matter
You'll usually find GFCI outlets in bathrooms, kitchens, garages, unfinished basements, laundry areas, outdoors and anywhere water and electricity share space. The U.S. Consumer Product Safety Commission recommends them in kitchens, bathrooms and other higher-shock-risk spots, and points to the National Electrical Code locations like garages, unfinished basements and near laundry tubs or wet-bar sinks.
A regular outlet won't cut power the same way when current leaks to ground. That's why a GFCI that has quietly failed is worse than no GFCI at all. You think you're protected, and you're not.
Pressed for time? Start with the bathroom and kitchen GFCIs, then hit the garage and outdoor ones. Those are the ones that see the most moisture.

How I test a GFCI in about 10 seconds
The CPSC's basic monthly test looks like this:
1. Plug a lamp or nightlight into the outlet and turn it on. 2. Press TEST. The light should go out, and the RESET button may pop out. 3. Press RESET. The light should come back on.
If the light never went out when you hit TEST, the GFCI isn't protecting that outlet. Stop using it and call a qualified electrician. If RESET won't restore power, leave it alone and call a qualified electrician. Don't keep pressing the buttons hoping they'll "catch." Don't open the electrical panel to chase a dead GFCI circuit. Panel work is for a qualified electrician.
Some older homes have a GFCI breaker in the panel instead of (or in addition to) GFCI outlets. Those need monthly testing too, but if you're not sure which breaker it is, or the breaker won't reset cleanly, call a qualified electrician rather than experimenting.
Stick a small note on the inside of a cabinet door: "GFCI — test on the 1st." Once a month is the habit that matters.

What to do when a GFCI trips or won't reset
A GFCI that trips once after a wet plug or a faulty appliance can be normal. Unplug what's in that outlet, dry things off, and try RESET once. If it holds, test the appliance somewhere dry before you trust it again.
If the GFCI trips again right away, won't reset at all, feels warm, smells hot, or sparking shows up at the outlet, stop. Leave the outlet alone and call a qualified electrician. Never open the panel yourself to force a reset or swap a breaker.
Outlets that feel warm, keep tripping or won't reset need a pro. Call me at (470) 999-7395. A $79 diagnostic is how I track down whether it's the outlet, the appliance or the circuit.
