Step-by-Step Guide: Installing a Lutron Diva Dimmer Light Switch
Are you looking to upgrade your home's lighting with a Lutron Diva dimmer switch? You've come to the right place. This comprehensive guide will walk you through the process, from gathering tools to testing your new switch. Remember, safety first! Always turn off power at the circuit breaker before starting any electrical work.
Tools and Materials Needed
Before you begin, ensure you have the following tools and materials:
- Lutron Diva dimmer switch
- Wire stripper
- Screwdriver (flathead and Phillips)
- Needle-nose pliers
- Wire connectors (wire nuts)
- Electrical tape
- Non-contact voltage tester
Step 1: Turn Off Power and Remove the Old Switch
Start by turning off power to the circuit at the circuit breaker. Remove the old switch by unscrewing the screws, sliding the switch out, and disconnecting the wires. Always double-check that the power is off using a non-contact voltage tester.

Step 2: Identify and Prepare Wires
Your Lutron Diva dimmer switch should have three wires: a black (hot), a white (neutral), and a green or bare (ground). Identify these wires in your electrical box. The hot wire will typically be connected to the black wire on the old switch, the neutral to the white, and the ground to the green or bare wire.
Strip about 3/4" of insulation from each wire using your wire stripper. Be careful not to nick the wire underneath.
Step 3: Wire the Lutron Diva Dimmer Switch
Wire the Lutron Diva dimmer switch as follows:

| Lutron Diva Wire | Circuit Wire |
|---|---|
| Black (Hot) | Black |
| White (Neutral) | White |
| Green or Bare (Ground) | Green or Bare |
Connect the wires using wire nuts, twisting them clockwise to tighten. Wrap each connection with electrical tape for added security.
Step 4: Install the Lutron Diva Dimmer Switch
Slide the Lutron Diva dimmer switch into the electrical box, securing it with screws. Make sure the switch is level and the faceplate is flush with the wall.
Step 5: Test the Lutron Diva Dimmer Switch
Turn the power back on at the circuit breaker. Test the Lutron Diva dimmer switch by toggling the switch up and down. The light should dim and brighten smoothly.
If your switch doesn't work as expected, double-check your wiring and ensure the power is on. If you're still having trouble, don't hesitate to consult a professional electrician.
Congratulations! You've successfully installed a Lutron Diva dimmer switch. Enjoy your new lighting control and the added ambiance it brings to your home.
