# Wiring Diagram for Two 3-Way Dimmer Switches

A wiring diagram for two 3-way dimmer switches is an essential part of any home electrical wiring project. These diagrams show how the dimmer switches are interconnected with each other and the power source, allowing you to control the same light from two different locations. This type of wiring diagram is extremely helpful when you need to connect multiple dimmer switches in a single room or area. With a wiring diagram, you can easily identify the exact connections you need to make and understand how they work together to create a functional circuit.

## Understanding the Basics of Wiring Diagrams

Before attempting to wire two 3-way dimmer switches, it is important to understand the basics of wiring diagrams. A wiring diagram is a visual representation of a circuit that shows the connections between different components. It includes both the components themselves and the wires that run between them. Each component is labeled with a number or letter, making it easy to identify the connection points between them. When reading a wiring diagram, understanding what each symbol represents and its corresponding connection point is essential to completing the task safely and correctly.

## The Necessary Wiring for Two 3-Way Dimmer Switches

In order to properly connect two 3-way dimmer switches, you will need the following wiring components:

• Two 3-way dimmer switches

• Three-wire cable

• One electrical box

When wiring a two 3-way dimmer switch, it is important to use the correct gauge of wire for each connection. In some cases, you may need to use two different gauges of wire in order to make all the necessary connections. This is especially important when connecting the two switches together, as one switch will be designated as the “master” while the other is the “slave”. Additionally, you will need to ensure that the electrical box is large enough to fit all the necessary wires.

## Step-By-Step Guide to Wiring Two 3-Way Dimmer Switches

Now that you have all the necessary components for wiring two 3-way dimmer switches, here is a step-by-step guide on how to do so:

1. Connect the black wire from the three-wire cable to the common terminal on the master dimmer switch. Make sure to tighten the terminal screws securely.

2. Connect the red and white wires from the three-wire cable to the two traveler terminals on the master dimmer switch. Again, make sure to tighten the terminal screws securely.

3. Connect the red and white wires from the travel terminal on the slave dimmer switch to the two traveler terminals on the master dimmer switch.

4. Connect the black wire from the travel terminal on the slave dimmer switch to the common terminal on the master dimmer switch.

5. Finally, connect the black wire from the three-wire cable to the common terminal on the slave dimmer switch.

Once you have completed all of these steps, you will have successfully wired two 3-way dimmer switches. Remember to always double check your work before turning on the power, and to ensure all wires are securely connected. With this step-by-step guide, you should have no difficulty wiring two 3-way dimmer switches.
