Lutron CL Dimmer Wiring Diagram

Lutron CL Dimmers can be wired in a variety of ways, depending on the type of application. 

For a single-pole application, you will need to connect the black wire from the dimmer to the black hot wire in the wall box, the red wire from the dimmer to the red load wire in the wall box, and the ground wire from the dimmer to the green ground wire in the wall box.

A Lutron CL Dimmer is a type of dimmer switch that is designed to work with a wide range of dimmable light bulbs, including incandescent, halogen, CFL, and LED bulbs. CL Dimmers are known for their reliability and their ability to provide smooth, flicker-free dimming.

How Do You Wire Lutron CL Dimmer

The following wiring diagram and instructions show how to install a Lutron CL Dimmer in a single-pole application:

2. Take the old switch out of the wall box.
3. Connect the dimmer’s ground wire to the green ground wire in the wall box.
4. Connect the dimmer’s black wire to the wall box’s black hot wire.
5. Connect the dimmer’s red wire to the red load wire in the wall box.
6. Use the provided screws to secure the dimmer in the wall box.
7. Reconnect the power at the breaker box.

Three-Way Wiring

Three-way wiring is used when two switches control the same light fixture. This is often used in stairwells and hallways. The following wiring diagram shows how to install two Lutron CL Dimmers in a three-way application:

The instructions are quite the same as the single-pole application.

Four-Way Wiring

Four-way wiring is used when there are three or more switches that control the same light fixture. This is often used in large rooms with multiple entrances. The following wiring diagram shows the four-way application of the Lutron CL dimmer:
