GFCI (Ground Fault Circuit Interrupter) protection is a safety feature installed in electrical outlets to reduce the risk of electrical shocks and fires. It works by quickly shutting off power to the outlet if it detects a ground fault, such as when electricity is flowing through an unintended path, like water or a person's body. GFCI protection is commonly used in areas where water is present, such as bathrooms, kitchens, outdoor outlets, and garages, to prevent accidents and keep individuals safe. It is recommended to have GFCI protection in all outlets located near water sources to meet electrical safety standards.
