how do I wire a electrical timer?


I have an electrical timer with a red, a white, and a black wire, but the box only has a white and a black wire. What does the red wire connect to?

I would venture to guess that the red wire connects to the device being timed. Might not work in a switch loop scenario.

The white is providing power to the switch and the black is the switch controlled hot.

You do not have a neutral and the timer cannot be used with your setup.

The OP has not said that he/she is replacing a switch...you assumed that. For all we know, the box mentioned could contain a hot and grounded conductor.

Thank you Jim Port. I guess I'll return it and look for a different type. Any suggestions? I am timing a light.

This is the OPs post

Sounds like there is no option, either it is a switch loop as I posted or it is a hot and a neutral with no load wire. It would be unusual to replace a receptacle with a timer.

I just did not want to assume anything, and I only asked those questions to learn all the details first.

Who posted about a switch loop first?
