What Is a GFCI Outlet?
GFCI stands for Ground Fault Circuit Interrupter. It monitors the flow of electricity and shuts off power in milliseconds if it detects a ground fault, meaning electricity is flowing somewhere it shouldn't (like through a person). That's what protects against electric shock.
You've probably seen the outlets with "TEST" and "RESET" buttons. Those are GFCIs. Massachusetts electrical code requires them in bathrooms, kitchens, garages, outdoor areas, and anywhere near water.
What Is an AFCI Outlet?
AFCI stands for Arc Fault Circuit Interrupter. It detects dangerous electrical arcs, the kind that can start fires inside walls where you can't see them. While GFCIs protect people from shock, AFCIs are designed to protect your home from electrical fires.
Massachusetts adopted the 2020 NEC (National Electrical Code), which requires AFCI protection for nearly all living areas, including bedrooms, living rooms, hallways, and dining rooms.
Does My Home Have Them?
If your home was built or went through a major renovation after 2002, you likely have GFCI protection in wet areas. AFCI protection is newer, so if your home is more than 10 years old, there's a good chance you don't have it.
Homes without proper GFCI and AFCI protection are technically out of code and present real safety risks. Upgrading is straightforward and relatively affordable.
How Much Does It Cost to Upgrade?
GFCI outlet replacement typically costs $100 to $200 per location. AFCI breaker installation runs $50 to $100 per circuit. A full safety assessment can identify exactly which areas of your home need attention.
