GFCI and AFCI

GFCI stands for ground fault circuit interrupter. AFCI is an arc fault circuit interrupter. While a GFCI outlet or breaker is installed to prevent electrical burns and fatal shocks, AFCIs help prevent electric fires.

GFCIs prevent humans from becoming a path to ground if there were a fault. GFCI outlets have sensors to measure the current moving in and out. When the current makes contact with a human or other abnormal changes in the current flow to ground, the GFCI senses this and interrupts the flow of the current by shutting down the circuit.

Because water conducts electricity, it is especially important to install and maintain GFCI outlets in areas where water and electricity could come in contact, including bathrooms, laundry rooms, kitchens, and garages. GFCI receptacles include two buttons, test and reset, which are typically black and red. Outlets should be tested once a month, and if the outlet stops working, reset the breaker.

AFCI breakers help prevent electric fires, caused when electricity leaks out of decaying or damaged wiring. Electric fires, which spread quickly through the wiring behind walls, are very deadly and can cause significant damage. Arc fault circuit interrupters sense electricity leaking from the wiring and shuts the system down. They also protect against electrical fires caused when appliances such as an iron or clock radio fault. AFCI outlets or circuit breakers are required in most rooms of your house.
