timer switch

I want to replace a standard single pole switch with a timer switch. The current single pole switch has a black wire and a white wire connected to it. The new timer switch has a black wire, white wire and a red wire. What do I do with the red wire ?

That new timer requires a dedicated neutral which you don't have.


Black - 120v hot
Red - switched 120 v
White - neutral


Do you only have the white and black wire in that switch box ?

No, there are three other switches in the same box. Can I splice the white into one of them ?

You don't have a neutral in the box. Verify that. If you have a bundle of white wires capped and stuffed in the back of the box, then you have access to a neutral. Doubtful that will happen. The white wires on the switches are technically "black" switch loops, so envision them as black, not white.

As PJ max explained, the wires on your timer switch need to be connected as:
Black - 120v hot
Red - switched 120 v
White - neutral
No, you cannot connect the white wire to any wire on any other switch. How are the other three switches wired?
