![]() The most often used “receptacle-type” GFCI, similar to a common wall outlet, is the type with which most consumers are familiar. The GFCI reacts quickly (less than one-tenth of a second) to trip or shut off the circuit. The GFCI will “sense” the difference in the amount of electricity flowing into the circuit to that flowing out, even in amounts of current as small as 4 or 5 milliamps. In a ground fault, electricity has found a path to ground, but it is a path the electricity was never intended to be on, such as through a person’s body.īecause of this potential for shock, GFCI protection is used to protect human life. Electricity always wants to find a path to the ground. They are most often found in kitchens, bath and laundry rooms, or even out-of-doors or in the garage where electric power tools might be used.Īccording to the National Electrical Code, a “ground fault” is a conducting connection (whether intentional or accidental) between any electric conductor and any conducting material that is grounded or that may become grounded. GFCIs are generally installed where electrical circuits may accidentally come into contact with water. If a person’s body starts to receive a shock, the GFCI senses this and cuts off the power before he/she can get injured. A ground fault circuit interrupter (GFCI) can help prevent electrocution.
