Ground fault circuit interrupters (GFCI) are used to monitor the amount of current going to and returning from equipment flowing through a circuit. If the flow is irregular, GFCIs interrupt the current. They help to prevent electrical fires and to reduce the risk of shock, burns, or electrocution. Designed to shut off power within 1/30th of a second, they are used with power tools, on construction sites, and near water sources in homes (kitchens, bathrooms, and laundry rooms).
