This guide walks you through the process, ensuring a safe and successful installation. Remember, always turn off power at the circuit breaker before starting and follow local electrical codes.
Understanding Your Lutron Diva Dimmer Switch
Before you begin, familiarize yourself with your Lutron Diva dimmer switch. It's a smart, wireless, and energy-efficient solution that replaces standard switches. The kit includes the dimmer switch, a wireless receiver, and mounting hardware. For this guide, we'll focus on the single-pole installation process.
Gather Your Tools and Materials
- Lutron Diva dimmer switch kit
- Wire stripper
- Screwdriver (flathead and Phillips)
- Needle-nose pliers
- Wire connectors (wire nuts)
- Electrical tape
- Non-contact voltage tester
Preparation: Turn Off Power and Remove the Old Switch
First, turn off power to the circuit at the circuit breaker. Use a non-contact voltage tester to ensure the power is off. Remove the old switch by unscrewing the mounting screws, disconnecting the wires, and pulling it out.

Wire the Lutron Diva Dimmer Switch
Step 1: Identify the Wires
In your electrical box, you'll find two wires: the black (hot) wire connected to the power source and the white (neutral) wire connected to the neutral bus bar. There might also be a green or bare copper wire (ground) connected to the ground screw.
Step 2: Connect the Wires
Strip about 3/4" of insulation from each wire using the wire stripper. Connect the black (hot) wire to the black wire terminal on the Lutron Diva dimmer switch. Connect the white (neutral) wire to the silver terminal. If you have a ground wire, connect it to the green terminal.
Step 3: Secure the Wires
Tuck the wires back into the electrical box, ensuring no wires are pinched or damaged. Secure the wires with wire connectors (wire nuts) and electrical tape if necessary.

Install the Wireless Receiver
The Lutron Diva dimmer switch comes with a wireless receiver that needs to be installed near the switch. Connect the receiver to the neutral wire and secure it in place using the provided hardware.
Mount the Lutron Diva Dimmer Switch
With the wires connected and the receiver installed, mount the Lutron Diva dimmer switch to the electrical box using the provided screws. Ensure the switch is level and securely fastened.
Test Your Lutron Diva Dimmer Switch
Turn the power back on at the circuit breaker. The Lutron Diva dimmer switch should now be functional. Test the dimmer by turning the switch on and off and adjusting the brightness.
Final Thoughts
Installing a Lutron Diva dimmer switch can transform your home's lighting and offer the convenience of smart home technology. If you're unsure about any part of the process, don't hesitate to consult a professional electrician. Happy upgrading!
