The answer to 'how to install GFCI outlet' is to replace a standard electrical outlet with a GFCI (ground fault circuit interrupter) outlet. GFCI outlets are designed to quickly shut off power if they detect a ground fault, which helps prevent electric shocks and fires. This is an important safety upgrade, especially in areas with water like bathrooms, kitchens, and outdoor outlets.
To install a GFCI outlet, first turn off power to the circuit at the circuit breaker. Remove the existing outlet and carefully disconnect the wires. Connect the new GFCI outlet by matching the wire colors - hot (black or red) to the brass terminal, neutral (white) to the silver terminal, and the ground (green or bare copper) to the green terminal. Secure the GFCI in the electrical box and install the faceplate. Turn power back on and test the GFCI to ensure it is working properly.
