Installing a GFCI outlet is a great safety upgrade for your home. First, always ensure the power is off at the circuit breaker. Connect the black wire to the "LINE" brass screw and the white wire to the "LINE" silver screw. The green or bare wire goes to the green screw. Once hooked up, carefully place the outlet into the box and secure it. What stage of the process are you at right now? Do you have safety gear ready for the installation?
