Digital Timer Switch Electrical Wiring Instructions
How to Wire a Timer Switch for Lighting: As described, the wiring will require four wires for the connections to the time switch.
Requirements for Most Digital Timer Switches
Electrical Question: I just bought a Pass & Seymour RT1W Digital Timer switch to replace my simple single-pole switch.
- My problem is that the installation instructions diagram doesn’t match my simple 1975 Constructed home, switch-box configuration which is one wire set – white, black, unshielded ground connected to nothing in the box.
- My new switch comes with FOUR wires:
- White (labeled Neutral)
- Black (labeled HOT, power from circuit box)
- Red (labeled LOAD, power to lamp or fan)
- Green (labeled GROUND)
The ground is easy, but do I connect the other THREE(White, Black, and Red) RT1 switch wires to the TWO (Black & White) I have left in my old switch box?

Thanks for your electrical wiring question Ron.

- Ron, the digital time switch that you have requires a separate neutral wire.
- Your wiring configuration will not work with this timer unless there is a neutral wire in the switch box.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
