Typical Lutron Caseta Wiring Diagrams
The wiring diagram varies based on the type of switch configuration you're installing. Below are common scenarios with detailed explanations.
1. Single-Pole Wiring (Standard Switch Replacement)
Purpose: Replace a standard switch controlling a single light from one location.
Wiring Components:
- Power source (Line)
- Load (Light fixture)
- Ground wire
- Neutral wire (if available)
Wiring Steps:
- Turn off the circuit breaker to ensure safety.
- Remove the existing switch and identify the wires:
- Connect the Line wire (hot) to the Red or Brass screw on the Caseta dimmer.
- Connect the Load wire to the Black or darker terminal on the dimmer.
- Connect the Ground wire to the green terminal on the dimmer.
- If there's a neutral wire, connect it to the neutral terminal on the dimmer (if required).
- Secure all connections, mount the switch, restore power, and test.
Diagram Summary:
```
Power Source (Line) ----> Red terminal
Load (Light) -----------> Black terminal
Ground ------------------> Green terminal
Neutral (if available) --> Neutral wire
```

2. 3-Way Wiring (Multi-Location Control)
Purpose: Control a light from two different locations, such as a hallway or staircase.
Components Needed:
- Lutron Caseta 3-Way Kit (includes switch and Pico remote)
- Neutral wire (if required)
- Traveler wires between switches
Wiring Steps:
- Turn off the power at the breaker.
- Identify the traveler wires connecting the existing switches.
- Connect the Line and Load wires as in single-pole wiring at the primary switch location.
- At the second switch location, connect the traveler wires to the Caseta dimmer switch terminals.
- If neutral wires are available, connect them accordingly.
- Mount the switches, restore power, and configure the Pico remote as needed.
Diagram Summary:
```
Power Source (Line) ----> Primary Switch (Red terminal)
Traveler Wires ---------> Secondary Switch (Traveler terminals)
Light Fixture ---------> Load terminal on primary switch
Ground wires ---------> Grounds
```

3. Multi-Location with Pico Remote Control
Purpose: Add wireless control without additional wiring.
Components:
- Caseta switch installed at one location
- Pico remote control mounted or wireless
Wiring Steps:
- Follow single-pole wiring for the main switch.
- Pair Pico remote with the Caseta switch via the Lutron app or pairing process.
- The Pico remote communicates wirelessly, requiring no additional wiring.

Tips for Proper Lutron Caseta Wiring
Correct wiring is crucial for system performance and safety. Here are some helpful tips:
Verify Power Off Before Starting
Always turn off the circuit breaker before beginning any wiring work to prevent electrical shock.
Identify Wires Correctly
Use a voltage tester to confirm wire function:
- Line (hot) wire: Usually black or red.
- Neutral wire: Usually white.
- Ground wire: Usually green or bare copper.
- Traveler wires: Usually are red, black, or sometimes white with markers.
Check Compatibility
Ensure your existing wiring supports the Caseta switches, especially the availability of neutral wires, which many Caseta models require.
Follow Manufacturer Instructions
Always refer to the official Lutron Caseta wiring diagrams provided in the user manual or on their website for specific models.

Troubleshooting Common Wiring Issues
Even with proper wiring, issues can arise. Here's how to troubleshoot common problems:
Switch Not Responding
- Confirm all wiring connections are secure.
- Ensure the breaker is on.
- Re-pair the Pico remote if used.
Lights Flickering or Dimming Issues
- Check that compatible bulbs are used.
- Verify wiring matches the diagram.
- Ensure neutral wire connections are proper if required.
Switch Not Turning On/Off
- Double-check hot and load wiring.
- Confirm ground connections are secure.
- Test the switch with a multimeter for continuity.

Frequently Asked Questions
How do I wire a Lutron Caseta dimmer switch into an existing wiring setup?
To wire a Lutron Caseta dimmer switch, turn off power at the circuit breaker, connect the switch's hot wire (usually black) to the line wire, connect the load wire to the fixture, and follow the specific wiring diagram provided in the Lutron Caseta manual. Ensure neutral wires (white) are connected if required by your model, and use the included Pico remote or app for control.
What is the wiring diagram for connecting a Lutron Caseta dimmer with a neutral wire?
For installations with a neutral wire, connect the line (hot) wire to the black screw on the dimmer, connect the neutral wire (white) to the neutral terminal on the switch, attach the load wire to the load terminal, and follow the diagram on the Lutron Caseta packaging or manual. This setup allows the dimmer to function properly and ensures compatibility with smart features.
Can I wire a Lutron Caseta switch in a multi-way (3-way or 4-way) setup?
Yes, Lutron Caseta switches can be wired in multi-way configurations using Pico remote controls instead of traditional three-way switches. The main Caseta dimmer is wired to the power source and load, and Pico remotes communicate wirelessly to control the switch. The wiring diagram involves connecting the main switch to power and load, with Pico remotes mounted at other locations.
What are common wiring mistakes to avoid when installing a Lutron Caseta dimmer?
Common mistakes include connecting the wrong wires (e.g., reversing line and load), neglecting to connect the neutral wire if required, not turning off power before installation, or failing to follow the specific wiring diagram for your setup. Always verify wire colors and consult the official wiring diagram for your model to ensure safe and proper installation.
Where can I find the official wiring diagram for my Lutron Caseta device?
Official wiring diagrams for Lutron Caseta products are available in the user manual included with the device, on the Lutron website under the product support section, or through their customer service. It's important to follow these diagrams carefully to ensure safe and correct installation.
