i am wiring a 110volt 3way switch and want to jump off the last 3 way to a single pole swich to another light?

Question

what wire or terminal do i use at my last 3 way

Answer 1

First you need to run a three wire (black, red, white, and a ground) and a two wire to the thee way switch that has the switch leg of the light that is already three wayed. then in the singlepole box the black and red of the three wire will go on the silver screws.(marked on the back of your three way switch) the black of the two wire will go to the common. cap off the old power wire (black and white). Make the white of the new and old two wire(the one ran from the old light and the one from the three way) together with a wire nut, and the grounds together. In the old three way box make all the white wires together and then the two black wires( one from the old light and the new one from the two wire that you ran over to that existing three way), and the grounds in their own wire nut. Now you should have the red and black of the new three way and the two travelers from the existing curciut( these two should be on the silver screws from the existing swith). Now you need a four way switch and your set, instructions for four way switching is on the back of box. Any questions email me at [e-mail]

Answer 2

You had a couple questions on this. Forget about the 3 way if you are trying to wire up a new light. I assume you want a new light and single switch to be independent. To have one light depend on the 3 way of another makes no sense.

What you need is power and neutral. What I think when you say "last" 3 way is the one that drives the light. But in any case, you cannot conclude either 3 way switch box has what you need. Are you running wires for the new light? It would be simpler to get power from a receptacle someplace. Without knowing exactly how your 3 ways are wired I cannot say if you can get unswitched power from it. If the power feed for your 3way light is at the light, you will probably not have a neutral at either 3 ways. To get correct advice, you really need to explain more fully what your situation is.

I'm also guessing you don't really know enough about this to be doing the work. For your own safety, I would recommend an electrician to do this work.

Answer 3

Can't be done. The two carrier wires alternate being "high" or "hot," so your light would only be on if the first two switches were in a given position. Also, to pass code, your neutral would have to come from the same location.

Answer 4

You need to do this at the *first* switch (or upstream from it), not the last. Once you add the traveller wire there should only be the light and the other switch.

Answer 5

cant do it properly without running another wire
