The answer to 'what is GFCI outlet' is a type of electrical outlet that helps protect against electrical shocks and electrocution. GFCI stands for Ground Fault Circuit Interrupter, and it is designed to quickly shut off power to an outlet if it detects a ground fault, which is an unintended flow of electricity. This can happen if a person touches a live electrical part, or if an appliance or tool becomes faulty.
GFCI outlets are commonly found in bathrooms, kitchens, laundry rooms, basements, and other areas where water may be present. They are required by electrical codes in many areas to help prevent electrical accidents and injuries. GFCI outlets have a 'test' and 'reset' button that allows you to check that they are functioning properly.
