How To Connect Multiple Light Fixtures To One Switch

I have a video showing how to connect a recessed light (pot light) to a switch but usually most people want more than one light on a switch. So this article will explain the easiest way to connect multiple light fixtures to one switch.But you may want to watch the video as well.

TIP: Remember always shut off the power at the electrical panel before starting any electrical work.

Basically the simplest way to have multiple lights on one switch is to run a power supply wire to the switch first. This would be a two wire cable (black, white, ground) take the black wire and connect it to one screw on the switch and connect the ground wire to a screw inside the electrical switch box mounted to the wall. Now run a two wire cable from the first light location to the switch box. Connect the black wire from it to the other screw on the switch and the ground wire to the box as before. Now take both white wires and connect them with a marrette wire connecter and fold them into the back of the electrical box out of the way. This will complete your switch connection. Now for all light locations run a two wire cable from one location to the next,this should give you two, two wire cables at every light location except the very last one, it should have only one two wire cable.

TIP: Make sure to allow extra wire at each switch or fixture to work with easily so that it is not to short. I like to leave about 16". Only strip about 6-8" of outer jacket off though. The outer jacket is the rubber coating holding all three individual wires together that make up the two wire cable.

To make the connection at all light locations do the following.... connect all same color wires together including the light fixture wires. So blacks to blacks, whites to whites and grounds to grounds using marrette wire connecters. Now carefully go back to each light and switch and tuck the wires into the areas provided and mount the lights and switches. Finally place proper bulbs into each fixture and then turn on power breaker and test switch and light operation.

You should now have a working set of lighting. Enjoy!
