A ground fault circuit interrupter (GFCI) can help prevent electrocution. If someone starts to receive a shock, the GFCI is designed to cut off the power before an injury can occur.
GFCIs are typically installed where electrical circuits may accidentally come into contact with water. They are most often found in kitchens, laundry or bathrooms, or even out-of-doors or in the garage where electric power tools might be used.
