Wiring Diagrams to Add a Receptacle Outlet
–Check local regulations for restrictions and permit requirements before beginning electrical work–
Add an Outlet from a Light Switch
This diagram shows the wiring for a new receptacle outlet added from a light switch. The switch must have an always-hot wire for the source and a neutral wire must be present for the return path. The hot source is spliced with a pigtail back to the switch, and to a new 2-wire cable running to the new outlet. The neutral is spliced in the switch box to both the existing light, and the cable to the new receptacle.
Add a Receptacle Outlet from a Light Fixture
This circuit diagram shows the wiring for a new receptacle outlet connected at a light fixture. The source at the fixture is always hot and a switch loop controls the light. New 2-wire cable runs from the fixture box to the new receptacle and the source hot, neutral and ground are splice to it along with a pigtail back to the fixture circuit. With this arrangement the new receptacle is always hot.
Add Receptacle to Light Fixture Circuit
Here a new receptacle is added to a light fixture circuit. The connections at the light fixture are spliced and extended to the new receptacle. With this arrangement the new receptacle will turn off and on with the light fixture.
Add a Receptacle to a 3 Way Circuit
Here a receptacle is added to a 3 way light circuit before the first switch. It is not controlled with the switches but is instead always hot. The source hot, neutral and ground are spliced to a 2-wire cable that runs to the new outlet. The 3 way switches and light are then wired in the usual way with the common on SW2 spliced to the source hot and the light hot wired to the common on SW1.
