Lutron 3 Way Dimmer Switch Wiring Diagram

By | July 31, 2022



When it comes to home automation, wiring can be overwhelming. That’s why a Lutron three-way dimmer switch wiring diagram is so helpful. A three-way dimmer switch allows you to control a light from two different locations, such as from the top of a staircase and from the bottom.

To start, you’ll need to identify what type of wall box your switch will be installed in. If it’s a standard single-gang box then your wiring should look like this: The black wire connects to the common terminal (usually the one in the middle), the red wire connects to the load terminal (on the right side when facing the switch lever), and the green wire connects to the ground terminal (on the left side when facing the switch lever).

Next, mount your switch and connect the wires. Be sure to tighten the end screws securely and use some electrical tape over them to ensure a safe connection. When making the connections, use the proper colors and twist the ends of the wires together in a clockwise direction. Once the switch and wiring are done, it’s time to map out the wiring for your second switch location. Here’s what that would look like:

Run a 14/2 or 14/3 wire from the first switch to the second switch. In the first switch box, you’ll need to use the traveler terminals to run the additional cable to the second switch. Make sure the black wire goes to the common terminal on the second switch, the red wire to the load terminal and the green wire to the ground terminal.

Once you have your wiring mapped out, you’re ready to attach it to the switch. Connect the two switches in parallel with the hot wire connected to the common terminal, the traveler wires connected to the traveler terminals and the neutral wire connected to the load terminal. Now you’re all set to test your dimmer switch!

As you can see, with a bit of knowledge and patience, you can easily install a Lutron three-way dimmer switch – and a Lutron 3-way dimmer switch wiring diagram makes the entire process much easier. With such a convenient way to add home automation to your living space, you can turn any room into your own personal paradise.
