How To Add A Light Fixture To Existing Circuit
How to add a light switch to an existing circuit. You can add a switch capability to an existing electrical circuit by adding a light switch in the middle of the circuit. All you need are basic tools and wiring knowledge. Wrap the black wire from the existing light fixture around one screw on the right side of the original switch. Connect the hot wire to the side of the double switch that has the jumper tab between the terminals photo 7. Wrap the black wire from your new light fixture around a screw on the right side of the new switch. With a light switch in the circuit youll have control of on and off functions for any electrical devices that are on the circuit.
Wrap one black pigtail around the other screw and tighten both screws. The switch comes first in the new part of the circuit and new 2 wire cable is run to it from the outlet. Adding a light fixture mid circuit you can usually install a light fixture between an existing one and the switch by cutting the cable to the existing fixture at the location of the new one inserting the ends of the cable into the electrical box for the new fixture and pigtailing the new fixture onto these wires. Complete the project by mounting the light fixture screwing the switch to the box and installing the cover plate. The neutral for the new light is taken from the receptacle and spliced to the new white wire and to a pigtail that connects back to the receptacle. From the switch new 2 wire cable is run to the new light location.
