What are GFCI and AFCI outlets?
A GFCI protects people from shock by cutting power when current leaks to ground — used near water (kitchens, baths, garages, outdoors). An AFCI protects the home from fire by detecting dangerous arcing in wiring — used in most living areas. Modern code requires both where specified.
The difference in one line each
- GFCI (ground-fault): shock protection. Trips when electricity finds an unintended path to ground — like through a person in a wet area.
- AFCI (arc-fault): fire protection. Trips when it detects the erratic sparking of a damaged wire or loose connection.
Why they trip
A GFCI trips on moisture or a genuine ground fault; an AFCI trips on arcing, which can be a real wiring fault or, sometimes, a nuisance from certain motors. Repeated tripping is worth investigating rather than swapping the device for a standard one — that removes the protection code intends.
Common questions
Do I have to have GFCI and AFCI outlets?
Current electrical code requires GFCI protection in wet/damp areas and AFCI protection in most living spaces. Older homes may predate these rules; adding them during electrical work improves safety and code compliance.
How we build this guidance
This guide is written and reviewed by the Lazarine AC team — a local heating, cooling and electrical company serving Fort Bend County since 2000. It reflects how we actually diagnose and quote work here, not generic national copy. It's general information, not a substitute for an on-site diagnosis of your specific system.
