As most adults understand, water and electrical circuits do not mix but children may not realize the danger. A Ground Fault Circuit Interrupter (GFCI) is designed to overcome this problem by “tripping” and cutting off the flow current if someone inadvertently completes the circuit while standing in water. GFCIs work by comparing the input current on the “hot” side to the output current on the neutral side. If there is even a slight difference at all – a few milliamps is all it takes – the device will shut off the flow of electricity. It works automatically and is can truly be a life saver.
