Dimmer switches are an essential component of modern lighting systems. They allow you to adjust the brightness of your lights to create a mood or ambiance. One of the most popular brands of dimmer switches is Leviton. In this article, we will discuss how to wire a Leviton dimmer switch for a 3-way circuit. We will provide step-by-step instructions, diagrams, and frequently asked questions to help you install a Leviton dimmer switch with ease.
What is a 3-Way Switch?
A 3-way switch is a type of switch that allows you to turn a light fixture on or off from two different locations. For example, you might have a hallway with a light fixture that can be turned on or off from either end of the hallway. In this case, you would need a 3-way switch to control the light fixture from both locations.
A 3-way switch has three terminals: one common terminal and two traveler terminals. The common terminal is usually black and the traveler terminals are usually brass-colored. The common terminal is connected to the power source and the two traveler terminals are connected to the light fixture.

FAQs
How do I know which wire is the common wire on a 3-way switch?
The common wire is usually black, although it can be a different color. Look for the wire that is connected to a different screw than the traveler wires.
Can I use a Leviton dimmer switch with any type of light bulb?
No, you cannot. Leviton dimmer switches are designed to work with certain types of light bulbs, such as incandescent, halogen, and dimmable LED and CFL bulbs. Check the dimmer switch package or manufacturer’s website to see what type of bulbs are recommended.
Do I need a special dimmer switch for a fan?
Yes, you do. A fan control switch is designed specifically for controlling the speed of a ceiling fan. A regular dimmer switch is not designed to control the motor of a fan and may cause damage to the fan or the switch.
Can I install a Leviton dimmer switch myself?
Yes, you can. However, if you are not comfortable working with electricity or electrical wiring, you should hire a licensed electrician to do the installation for you.
What should I do if the Leviton dimmer switch does not work?
First, check to make sure that the wiring is correct and that the dimmer switch is compatible with your light bulbs. If the wiring and bulbs are correct, then the dimmer switch may be defective and should be replaced.
Conclusion
Wiring a Leviton dimmer switch for a 3-way circuit is a relatively simple process, but it does require some knowledge of electrical wiring. By following the instructions provided in this article, you can install a Leviton dimmer switch with ease. Remember to turn off the power supply before working on any electrical wiring and to test the switch before using it.
