How do you install a GFI (Ground Fault Circuit Interrupter)?

To install a GFI, first turn off the power to the circuit at the breaker box. Remove the outlet cover and disconnect the wires from the old outlet. Connect the wires to the corresponding terminals on the GFI, following the manufacturer's instructions. Secure the GFI in place and replace the outlet cover. Turn the power back on and test the GFI to ensure it is working properly.
