What Color Wires Go Together For A Motion Sensor Light Switch?

Everyone knows how much of a hassle it can be to replace a light switch. That uncertainty is even greater when installing a motion sensor light switch. It's especially concerning when you have to match the right color wires in order to get the switch operational. After all, these switches are designed to be wired into an existing electrical system, and it's important that the colors match correctly in order for the switch to work properly.

Fortunately, solving this problem doesn't have to be that difficult. Most motion sensors will include a wiring diagram. By following the diagram, the multiple colors of wires should be properly matched. Usually this means white wires need to be 'hot' and connected to one side of the switch. While, black wires should be connected to the other side of the switch. To make sure everything is done properly, it's always best to use a non-contact voltage tester before making any connections. This device can easily detect hot wires from far away, quickly warning against any potential danger.

It's also important to note that there may be multiple colors of ground wires. Depending on the type of switch and its configuration, these wires need to be combined together and connected to the green wire in the box itself. Once the ground is secured, the red wire should be connected to the switch. This will complete the installation process and allow the switch to function as intended.

By following these simple steps, installing and connecting a motion sensor light switch is a breeze. Whether you're a professional electrician or a home DIY-er, you can rest assured that the job will be done right.
