Common questions
Why does my GFCI keep tripping?
Moisture, a worn outlet, or a fault on the circuit can cause it. If it trips again right after a reset, have an electrician check it.
Do I need GFCI outlets?
Code requires them in kitchens, baths, garages, basements and outdoors. Older homes may not have them, and adding them is a safety upgrade.
Can I add an outlet anywhere?
Not always. The wires must come from a nearby circuit with room to spare, and walls or finished ceilings can add labor. An electrician can price the route.
