A GFCI outlet is a Ground Fault Current Interrupter. It is an electrical device built into an electrical outlet that can prevent injury from contact with electrical appliances or a short circuit in the event that water should come into contact with the outlet. These devices are now required in new homes in bathrooms, kitchens, garages and outdoors. If remodeling one of these areas in your home, GFCI outlets are a wise investment, even if they are not required in your locality.
