Arc fault circuit interrupters, or AFCIs, are safety devices that protect your home against electrical fires caused by damaged wiring. You can damage wires in all kinds of ways, like driving nails through them, closing a door on them, having loose connections, or overheating cords under rugs.

AFCIs are designed to detect arcing issues and shut off power to the affected circuit. AFCIs are so effective that the CPSC estimates that 50% of electrical fires can be prevented by them. That’s why AFCIs are required by code in certain areas of the home, like living rooms, bedrooms, closets, kitchens, and laundry areas.

By having AFCIs installed, you can help protect your home and your family from electrical fires. Be smart and stay safe.
