GFCI stands for Ground Fault Circuit Interrupters.  GFCI monitors the balance of electrical current moving through the circuit.  If an imbalance occurs, GFCI cuts off the electricity.  Its purpose is to prevent fatal electrical shocks. As you know, water and electricity are a deadly combination.  Since both are necessary in kitchens and bathrooms, all switches, sockets, breakers and circuits for those rooms should be GFCI protected for your family’s safety.
