A ground fault circuit interrupter (GFCI) can help prevent electrocution. 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. GFCIs are generally installed where electrical circuits may accidentally come into contact with water. They are most often found in kitchens, bath ...The parallel impedance limits the fault current to a level the system can handle, and a breaker clears the fault some time later.
