What is the purpose of GFCI protection?

The purpose of Ground Fault Circuit Interrupter (GFCI) protection is primarily to prevent electrical shocks. GFCI devices are designed to monitor the electrical current flowing through a circuit and detect any imbalances between the live (hot) and neutral wires. If a ground fault occurs, such as when water is involved or a person comes into contact with the energized conductor, the GFCI quickly disconnects the power supply to prevent injury or death from electric shock.

This function is particularly critical in areas where electrical circuits are more likely to come into contact with moisture, such as bathrooms, kitchens, and outdoor locations. While preventing fires and enhancing circuit performance are important aspects of overall electrical safety, the primary role of GFCI devices is focused on the immediate protection of individuals from potential electrical hazards. Reducing energy consumption is not a feature or function of GFCIs; they are safety devices rather than energy-saving devices.
