GFCI (Ground Fault Circuit Interrupter) outlets are used to reduce the risk of electric shock caused by ground faults. They are equipped with Test and Reset buttons and sometimes an indicator light. They are designed to shut off an electric circuit if the electricity is traveling outside of its intended path. GFCI receptacles work by comparing the currents going in and out and disconnecting them if the difference exceeds 4-6 milliamperes. GFCI outlets are required in many potentially wet locations like kitchens, bathrooms, unfinished basements, garages, outdoors, and anywhere near sinks. At HomElectrical, we also carry tamper resistant (TR) and weather resistant (WR) GFCI outlets. Our tamper resistant GFCI receptacles contain an internal, spring-loaded shutter that does not allow foreign entry and our weather resistant GFCI receptacles are made with more durable housing and corrosion-resistant metal components that resist both UV lights and extreme temperatures.
