Wiring a Lutron Diva Dimmer: A Comprehensive Guide
Embarking on a DIY home improvement project? Installing a Lutron Diva dimmer can enhance your space's ambiance and energy efficiency. This guide walks you through the process of wiring a Lutron Diva dimmer, ensuring a safe and successful outcome.
Understanding Lutron Diva Dimmers
Lutron Diva dimmers are popular for their sleek design, smooth dimming, and compatibility with various bulbs, including LED, CFL, and incandescent. They're available in single-pole, 3-way, and multi-location configurations. Before you start, ensure you have the correct model for your needs.
Safety First: Preparation
Before you begin, turn off the power to the circuit you'll be working on at the main panel. Use a non-contact voltage tester to confirm the wires are dead. Gather your tools: wire strippers, screwdriver, needle-nose pliers, and a voltage tester.

Step-by-Step Wiring Guide
Single-Pole Installation
Single-pole dimmers are the simplest to install. Here's how:
- Remove the existing switch and the electrical box cover.
- Identify the black (hot) wire, white (neutral) wire, and green or bare (ground) wire.
- Strip about 3/4" of insulation from each wire.
- Connect the black wire to the dimmer's black terminal, the white wire to the silver terminal, and the ground wire to the green terminal.
- Secure the wires with screws, ensuring they're tight but not over-tightened.
- Reattach the electrical box cover and install the Lutron Diva dimmer.
3-Way Installation
3-way dimmers allow you to control a light from two locations. Follow these steps:
- Turn off power at the main panel and confirm wires are dead.
- Remove the old switches and electrical box covers.
- Identify the black (hot) wire, white (neutral) wire, and ground wire at each location.
- At the first location, connect the black wire to the common terminal (usually marked 'COM') and the white wire to the silver terminal.
- At the second location, connect the black wire to one of the traveler terminals (usually marked 'TRAVELER A' or 'TRAVELER B') and the white wire to the other traveler terminal.
- Connect the ground wires to the green terminal at both locations.
- Install the Lutron Diva dimmers and reattach the electrical box covers.
Multi-Location Installation
Multi-location dimmers allow you to control a light from more than two locations. The process is similar to a 3-way installation, but you'll have more traveler wires to connect.

Testing Your Lutron Diva Dimmer
Once everything is wired up, turn the power back on at the main panel. Test your new dimmer by turning it on and off, and adjusting the light level.
Troubleshooting Common Issues
If your dimmer isn't working, double-check your wiring. Ensure all connections are tight and that you've connected the wires to the correct terminals. If you're still having issues, consult Lutron's support resources or consider hiring a professional electrician.
