Ground Fault Circuit Interrupter
Definition and meaning of Ground Fault Circuit Interrupter in real estate.
A ground fault circuit interrupter (GFCI) is an electrical safety device designed to shut off electric power quickly when it detects an imbalance in the current. It helps prevent electrical shocks and fires by interrupting the flow of electricity within milliseconds.
In more detail
These devices are standard safety features in modern homes, especially in areas where water is present, such as kitchens, bathrooms, garages, and outdoor locations. When a GFCI detects that current is leaking or taking an unintended path to the ground, it immediately cuts the power.
Home inspectors routinely test these outlets during a home sale to ensure they are functioning properly. Replacing standard outlets with GFCI outlets is a common and affordable safety upgrade recommended for older properties.

Frequently asked questions
Why does my GFCI outlet keep tripping?
A GFCI outlet trips when it detects an electrical leak or moisture in the circuit. It can also trip if the outlet itself is old and failing, or if a connected appliance has an electrical fault.
How often should I test my GFCI outlets?
Most manufacturers and electrical safety organizations recommend testing GFCI outlets once a month by pressing the 'test' button to ensure the power cuts off.
