Overview of the Lutron Sunnata 4-Way System
What is a 4-Way Wiring System?
A 4-way wiring system allows a light fixture to be controlled from three or more locations. This setup typically involves two 3-way switches at the ends and one or more 4-way switches in between. The Lutron Sunnata line offers modern, sleek switches and dimmers compatible with this wiring configuration, enabling seamless multi-location control with dimming capabilities where applicable.
Components Involved in the Wiring System
- Dimmer/Switch Units: Lutron Sunnata dimmers or switches, typically installed at the end and middle control points.
- Traveler Wires: Two wires that connect switches in a 4-way configuration, carrying the switching signals.
- Line (Hot) Wire: Supplies power from the breaker panel to the first switch.
- Neutral Wire: Completes the circuit, often required for dimmers.
- Load Wire: Connects the switches to the light fixture.
Key Features of Lutron Sunnata 4-Way Wiring
The Sunnata line is designed to integrate easily with existing wiring setups, offering features such as:

Preparation Before Wiring
- Turn off the main power at the circuit breaker to ensure safety.
- Verify that the power is off using a voltage tester.
- Gather necessary tools: screwdriver, wire stripper, voltage tester, and wire connectors.
- Identify the existing wiring configuration and the placement of switches and fixture.
Wiring the 4-Way System
The wiring process involves connecting the line, load, traveler wires, and ground appropriately. Below is a simplified explanation of the typical wiring diagram for a 4-way system using Lutron Sunnata switches.
Basic Wiring Diagram Explanation
- Power Source (Line): Connect the hot wire (usually black) from the breaker panel to the first switch's line terminal.
- First Switch (3-Way): Connect the line wire to the common terminal. Connect traveler wires (usually brass screws) to the two traveler terminals.
- Intermediate Switch (4-Way): Connect traveler wires from the first switch to the 4-way switch's traveler terminals. Connect traveler wires from the 4-way switch to the next switch.
- Last Switch (3-Way): Connect traveler wires from the previous switch to this switch's traveler terminals. Connect the common terminal to the load (light fixture).
- Load (Light Fixture): Connect the fixture's hot wire to the load terminal of the last switch. Connect the neutral wire directly to the fixture, completing the circuit.
- Ground Wires: Connect all ground wires (green or bare copper) together and attach to the switches' ground terminals and the electrical box if grounded.

Diagram Overview
The wiring diagram visually represents how the components are interconnected. It highlights the flow of current and the connection points for travelers, line, load, neutral, and ground wires. Below is a simplified outline of the wiring diagram:
- Power source connects to the first switch's common terminal.
- Two traveler wires run between the first switch and the 4-way switch.
- Another set of traveler wires connects the 4-way switch to the last switch.
- The last switch's common terminal connects to the light fixture's hot wire.
- Neutral wire from the power source connects directly to the fixture.
- All ground wires are interconnected.
Important Notes for Correct Wiring
- Ensure the switches are rated for the load and compatible with dimming if dimming control is desired.
- Use proper gauge wire (typically 14/2 or 12/2) as per local electrical codes.
- Follow the wiring diagram precisely to avoid malfunction or damage.
- Consult the Lutron Sunnata installation manual for specific wiring instructions related to your model.
Common Troubleshooting Tips
Switches Not Controlling Light Properly
- Check all traveler wires for secure connections.
- Verify that the common terminals are correctly wired.
- Ensure power is correctly supplied and the circuit breaker is on.
- Test each switch individually to confirm functionality.
Flickering or Dimmer Not Working Correctly
- Check if the dimmer is compatible with the type of bulb installed.
- Ensure neutral wiring is correctly connected if required.
- Inspect for loose wires or damaged components.
Safety Precautions
- Always turn off power before working on electrical wiring.
- Use insulated tools to prevent electrical shock.
- If unsure about wiring connections, consult a licensed electrician.

Frequently Asked Questions
What is the wiring configuration for a Lutron Sunnata 4-way switch setup?
The Lutron Sunnata 4-way wiring setup typically involves connecting two 3-way switches with a 4-way switch in between, using traveler wires and a common wire. The diagram illustrates how to connect the hot, traveler, and load wires properly to ensure seamless switching between multiple locations.
How do I identify the traveler wires in a Lutron Sunnata 4-way wiring diagram?
In the wiring diagram, traveler wires are usually represented as two wires connecting the two 3-way switches and the 4-way switch. They are often color-coded (e.g., brass or red terminals) and run between the switches to carry the switching signals, enabling the control from multiple locations.
Can I install a Lutron Sunnata 4-way switch without an existing 3-way switch?
No, a 4-way switch requires at least two 3-way switches to function properly. The wiring diagram shows how to connect multiple switches in a multi-location setup, but it cannot be used to replace a single switch without existing switches in place.
What are common mistakes to avoid when wiring a Lutron Sunnata 4-way switch?
Common mistakes include incorrect wiring of traveler wires, mixing neutral and hot wires, and not following the wiring diagram precisely. Always turn off power before wiring, double-check terminal connections, and consult the specific wiring diagram for your switch model to avoid electrical hazards.
Where can I find the official wiring diagram for the Lutron Sunnata 4-way switch?
The official wiring diagram can be found in the Lutron Sunnata switch installation manual, available on the Lutron website or included in the product packaging. Additionally, licensed electricians and electrical supply stores can provide guidance and printed diagrams for proper installation.
