Wiring Diagrams for Multiple Wall Outlets

This page contains several diagrams for wiring 2 or more receptacle outlets in a series. Wiring for multiple ground fault circuit interrupters (gfci) and standard duplex receptacles are included.

These drawing illustrate circuits with 15 amp devices and 14/2 awg cable. Existing household circuits may be 15, or 20 amps for lights and wall outlets. When working with 20 amp circuits use 12 awg cable and 20 amp devices.

Wiring Multiple Receptacles in Series

This diagram shows the wiring for a series of receptacles in one circuit. Two–conductor cable is run between boxes and the ground is spliced and connected to each device. The hot and neutral terminals are used to make the circuit connections and pass current from outlet to outlet. This eliminates the need for pigtail splicing and wire nuts that can crowd an outlet box.

Wiring Multiple Ground Fault Circuit Interrupter Receptacles

Here multiple gfci receptacles are wired together. Two–conductor cable is run between gfci's and the hot, neutral and ground from the source are spliced with a pigtail to the line terminals at each device. The load terminals are not used and each device provides its own protection in this ground fault circuit interrupter wiring.

Wiring Multiple Duplex Receptacles and a GFCI

In this wiring a gfci receptacle is added at the end of a series of outlets. The first duplex receptacle is connected to the source and 14/2 cable runs from box to box. The hot and neutral terminals on the devices are used to pass current and the ground wire is spliced to each. The load terminals on the gfci are not used and it does not protect the other outlets in the circuit.

In this wiring diagram one gfci outlet protects multiple duplex receptacles. The gfci line terminals are connected to the source and 14/2 cable runs from outlet to outlet. The load terminals on the gfci are wired to the first duplex receptacle and the following devices are connected using the hot and neutral terminals. The ground wire is spliced to each device.
