Here one ground fault circuit interrupter protects multiple duplex receptacles coming after it, known as multiple-location protection. Two-wire cable runs from the gfci to all the following receptacles. The line terminals on the gfci are connected to the circuit source and the load terminals are connected with a pigtail splice to each of the following receptacles. This keeps each duplex connected directly to the gfci.
Run the cable through the clamp and tighten it down. Splice the cable wires to the fan wires using a pigtail splice and a wire nut. Connect the ground to the grounding terminal in the connection box and the ground wire from the fan, if there is one.
In this diagram multiple ground fault circuit interrupter receptacles are wired together using pigtails. Two-conductor cable is run between gfci’s, and the hot, neutral and ground wires from the source are spliced to the line terminals at each device. The load terminals are not used and each device provides its own, single-location protection.
This diagram illustrates the wiring for a circuit with gfci receptacles followed by a light and switch. By connecting the switch to the load terminals on the gfci, the light is protected against ground faults as well.
