How To Wire A Switch Off An Outlet

Three wire cable runs from the switch to the outlet providing two hot wires to that location.

How to wire a switch off an outlet. Disconnect the live wire from the switch and splice it together with the black wire going to your new outlet adding a 6 inch length of spare black wire of the same gauge to make a pigtail. Unscrew the outlet and use a voltage tester to double check that the power is off. Mark the wire wire with black electrical tape at each end and use it for the power out. Twist the three wires together clockwise and screw on a wire cap then connect the short wire back to the switch.

Use the black wire as the power in. With either lead touching a ground wire bare copper touch the other lead first to the neutral terminals silver colored then to the hot terminals gold colored. The source hot at the switch is spliced with the red cable wire to the outlet and a pigtail to the switch. The second terminal of switch then connected back to the brass terminal of outlet.

When that s done you can treat the cable coming from the outlet into the switch box as a regular line cable. The black cable wire runs from the switch to the bottom half of the outlet. At the switch box the white neutral wires are spliced together and the ground wires are spliced and a pigtail wire is added and attached to the green ground screw on the light switch frame. With this example these two wires are configured to break the circuit power and send the power to the switch and then back to the outlet.

Use the suitable voltage and ampere rating of switch with appropriate wire size and proper size mcb according to the load rating. Switch off the main circuit breaker to make sure the power supply is off before wiring a gfci outlet. The incoming power from the outlet is attached to one of the light switch screw terminals and the black wire of the cable leading to the light fixture is attached to the other light switch screw terminal. Wiring an outlet to the combo switch outlet.

Connect the black wire to one of the switch terminals and the black wire going to the light fixture to the other switch terminal. At the receptacle the red connects to the top half of the outlet. Instead of running a separate pigtail from the hot wire to each switch just leave the hot wire extra long. If the light glows with either contact the circuit is still live.

To add an additional outlet to the combo device simple connect the line neutral and ground terminals as shown in the fig below. Connect the last switch in the usual manner looping the wire around the screw in a clockwise direction. Verify the load and line terminals while installing a gfci for protection. This way the outlet is wired and controlled on off through the switch.

Twist the white wires together and cap them and connect the ground wires to the ground terminal. In this wiring diagram the builtin switch in the combo device controls a lighting point whereas outlet can be used for other loads.
