A typical application for this method would be to protect more than one bathroom, or the all of the receptacles in your garage.

Below you will see some photos of recent projects that I have selected to help you with your project.

The GFCI Receptacle will have LINE and LOAD areas to attach your wires to. The "LINE" is the set of wires coming from the panel or power source, the "LOAD" is the wire set leaving the receptacle box to the other downstream receptacles to be controlled by the GFCI.
