Lutron 3-Way Dimmer Switch With Diagram | Complete Guide

On your property, there might be a few different switches, and each one has a somewhat different function. However, establishing a connection between them might not be a straightforward task for everyone.

A good example is the Lutron three-way dimmer switch. During this procedure, you might find that having a Lutron 3 way dimmer switch Wiring diagram is quite helpful.

The process of wiring a 3-way dimmer switch is somewhat more complicated than the process of wiring ordinary switches. The first thing that must be done is to turn off the primary source of power, which is then followed by wiring the dimmer switch and, lastly, troubleshooting.

In addition to the wiring diagram, I will also provide step-by-step instructions on how to correctly wire and install a Lutron 3-way dimmer switch.

Guide to Wiring a Lutron 3-Way Dimmer Switch:

How do you wire a 3 way Lutron dimmer switch?

The entire procedure of wiring a Lutron 3-way dimmer switch will be described sequentially throughout this segment. I will also provide a wiring diagram so that you may find it easier to make the necessary connections needed.

1. Gathering Necessary Tools

There a quite a few different tools that you would need before proceeding with the installation of the Lutron 3-way dimmer switch. These tools and equipment are mentioned below.

Which tools are necessary to wire a Lutron 3-way dimmer switch?

Rubber Gloves
Rubber Boots
Screwdrivers
Wire Strippers
Voltage Testers
Electrical Tape
Extra Wires
Three Way Switches

A three-way switch is necessary to wire a Lutron 3-way dimmer switch on any circuit. You will understand why it is necessary once you proceed to the wiring phase of the procedure.

2. Turning off the Power

You must turn off the electricity, shutting off the supply to your entire house before installing a Lutron 3-way switch. As it is extremely risky to work with live wires.

How to turn off the power?

Locate the main breaker of your household and identify the breaker that supplies power to the circuit you will be working on.
Flip the switch after you have figured out the proper circuit breaker.
To check whether the power has turned off, you may check the LED indicators of your electric panels.
If your board does not have an LED indicator, you can use a voltage tester to test for power.
Take necessary safety precautions before proceeding with any electrical operations. Such as wearing rubber boots and gloves.

3. Wiring the Lutron 3-Way Dimmer Switch

The most crucial step in the entire process is the wiring phase. You must make sure that the wiring is done properly and accurately to ensure that the Lutron 3-way dimmer switch will work properly. The wiring procedure as well as the wiring diagram will now be provided below.

How to wire a Lutron 3-way dimmer switch?

Make sure to wear appropriate safety gear (such as rubber boots and gloves) before proceeding with the operation.
Check to see once again if the power has been actually turned off, and the circuit is safe to be operated on. You can do this with the help of the voltage tester mentioned before.
Remove the switchboard from the wall (if any) and gain access to the wires or cables inside.
Make sure to pay close attention to the terminals provided in the diagram above (Fig 1).
Travelers from the first switch and the dimmer travel through the three-wire cable to the Lutron 3-way dimmer switch and connect to the respective terminals.
You could also connect the ground wire (green cable) to the 3-way switch if you prefer as it will provide greater safety to the appliance and the user.
Mark the white wires as hot, so that you can recognize them later on.
Now, connect those traveler wires to the Lutron 3-way dimmer switch, along with the ground cable.
Now, the hot wire from the dimmer, and the white wires marked as hot from the first switch, travel to the light fixture and are connected to the neutral and hot terminals respectively.
The connections of each stage must be made secure so that there are no loose wires. Exposed wires also have to be covered up with electrical tape so that no short circuits can occur within the installation.

Troubleshooting

After installation, troubleshooting is necessary to make sure that even a 3-way Lutron dimmer switch is functioning properly, and it is an important step.

The steps that must be done in order to troubleshoot the Lutron 3-way dimmer switch are listed below. The procedure might differ from testing a three-way switch.

How to troubleshoot the Lutron 3-way dimmer switch?

After you have finished installing everything, you should go back to the main circuit breaker and turn the power back on.
Check to see that each of the switches (both the 3-way switch and the dimmer switch) is operating as it should. They should each have their own individual control over the appliance to turn it on and off.
Try turning the light or device on using these switches individually.
Now try turning the light or device off using these switches individually.
Make sure that you are able to control the appliance using the dimmer switch. Check to see whether you can increase the brightness of the light bulb and also decrease it.
If each of the switches functions as it should, then the installation was carried out correctly.
In that case, you might need to double-check the wiring. Also, rewire if it is necessary.

Summary

If you wanted to learn about how to wire or install Lutron 3-way dimmer switch, I hope that this article was able to help you. I have also provided a Lutron 3 way dimmer switch wiring diagram. So that you may find it easier to make the connections.

If after reading this guide the process still seems frightening or confusing, don’t be hesitant to ask an experienced electrician for advice. Taking into account the fact that someone should never attempt to operate with electricity if they lack the necessary knowledge or confidence in their skills.
