What is a GFCI device or breaker?
A GFCI stands for Ground fault circuit interrupter. It is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the energized conductor and the return neutral conductor. Such an imbalance may indicate current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A lethal shock can result from these conditions. GFCIs are designed to disconnect quickly enough to prevent injury caused by such shocks. They are not intended to provide protection against overcurrent (overload) or short-circuit conditions.
What areas of my house should be GFCI protected?
GFCIs should be installed in all wet locations including unfinished basements, garages, anywhere outside the dwelling, within six feet of any sink, kitchens, bathrooms and powder rooms.
Simply.. if it can get wet and it plugs in, it needs to be on a GFCI protected circuit.
What are the buttons on my GFCI outlet for?
One button is the test button. When it is pushed, it should turn off the outlet and all other outlets that are tied to it. The other button is a reset button, which is used to turn the power back on to the outlet and any others that are tied into the outlet.
