Ground fault circuit interrupter (GFCI) blank face receptacles stop the flow of power in the event of a ground fault to prevent electrical shocks and protect equipment from damage. Also known as dead-front GFCI receptacles, they continuously monitor connections and close electrical circuits downstream if a failure occurs. GFCI devices have a button for periodic testing and another button to reset after a ground fault. They provide GFCI protection of large and permanently placed equipment like appliances, spa and tub pumps, and exhaust fans.
