Tips

  • When buying a Lutron motion sensing light switch, ensure it has all the functions you need (single-pole, multiple-pole, three-way, etc.).
  • Use longer screws if the ones provided with the switch are too short.
  • Consult additional resources (YouTube videos, manufacturer instructions) if you encounter difficulties.

Common Mistakes to Avoid

1. Incorrect Wiring

Reason: Connecting the wires to the wrong terminals on the switch can result in the light not working or causing electrical hazards.
Solution: Carefully double-check the wiring diagram provided with your Lutron switch and match the wire colors to the corresponding terminals.

2. Ignoring the Load Requirements

Reason: Using a switch with an insufficient amperage rating for your light fixture can lead to overheating and potential fire hazards.
Solution: Always verify that the Lutron switch's amperage rating is equal to or greater than the amperage rating of your light fixture.

FAQs

What type of wiring is required for a Lutron motion sensor switch?
Most Lutron motion sensor switches work with standard 3-way and single-pole wiring configurations. However, always check the specific wiring diagram included with your model to ensure compatibility with your existing setup. Incorrect wiring can damage the switch or create electrical hazards.
My lights flicker after installing the Lutron motion sensor switch. What could be wrong?
Flickering lights often indicate a loose wire connection or a problem with the neutral wire connection. Double-check all wire connections at both the switch and the junction box to ensure they are secure and properly tightened. If the problem persists, ensure your neutral wire is correctly connected; a missing or faulty neutral wire is a common cause of flickering.
