A GFCI (ground-fault circuit interrupter) cuts power in a fraction of a second when it senses current leaking where it shouldn't, such as through water or a person. They're one of the most important safety devices in a home, especially in humid Florida.
Where GFCI protection is expected
Electrical codes generally call for GFCI protection in bathrooms, kitchen countertop areas, garages, outdoors, laundry areas, near sinks, and around pools and spas. Newer code editions have expanded the list, and local adoption varies. Our outlet installation team can bring your home up to date.
Why GFCIs trip
Moisture in outdoor boxes, worn appliance cords, and old equipment with leaky insulation are the usual causes. Sometimes the GFCI itself is simply worn out.
When a GFCI won't reset
Check for another GFCI upstream that may have tripped. If none resets, there may be no power reaching it, or the device has failed. Call for electrical repair if you can't find the cause.
Test them monthly
Press TEST, confirm power cuts off, then press RESET. If it doesn't trip, replace it.
Quick answers
How long do GFCI outlets last?
Many last years, but they do wear out. Monthly testing tells you when.
Can one GFCI protect several outlets?
Yes, when wired correctly, it protects downstream outlets on the same circuit.
