💡 What is an arc fault circuit interrupter used for in home electrical panels? An AFCI detects hazardous electrical arcing and cuts power to reduce fire risk in wiring and connected devices. Here’s a quick breakdown: - Protects branch circuits from both series and parallel arc faults, lowering chances of electrical fires - Handy in bedrooms, kitchens, finished basements, and other living areas where wiring faults may occur - Works alongside thermal-magnetic protection to guard against overloads and short circuits
