3 way switch help


Newbie to the forum... and really to 3 way switches as well.

I'm having some problems on how to wire a new three way switch system. I have power coming into the first switch, then three lights, then the last switch at the end of the run. I ran 14/3 wire from the first switch, between each light, and then down to the last switch.

The switches are located at opposite ends of the building. Plan was to be able to operate the lights no matter which door I enter.

I've done wiring before, but never three way switches. Looking at several wiring diagrams on line, it seems that what I have done isn't correct. Problem I have is 10 diagrams have 10 different ways of wiring. Some show connecting the switches, then running the lights off of the second switch. Also, it seems that three lights complicate matters.

Thanks a lot in advance.

With the way you wired it you would need 14-4 between the lights. Can you still run cables to straighten this out?

I find the easiest way is power into SW1, xx-3 between switches, and from SW2 to L1. No need for hard to find cable and easy to keep the wiring straight.

I can, as nothing is covered up yet. Was hoping to be able to somehow salvage the wire that has already been run.

Can I use two pieces of 14/2 between the lights? If so, how do I run them?

I probably need to put a picture together, as I work better with diagrams than words.

You can just run a xx-3 between the switches. With the xx-3 between the SW2 and each fixture you will just ignore either the black or red.

Here is a diagram of how to wire what you have, although it is not the preferred way to do it.

Did you already cut up the 3 wire cable into little pieces daisy chaining from one light fixture box to the next?

If so it is possible you may run into overcrowded boxes if a 2 wire cable is also cut into little pieces and coexist daisy chaining from one light fixture box to the next.

Ideally a 3 wire cable should run directly between the switches. You can leave in place and use the pieces of a 3 wire cable daisy chaining through the boxes for the light connections. Add the direct cable between the switches to the mix. If the best route is up through the ceiling then this additional 3 wire cable can run unbroken past the outside of each light fixture box.

I rather run like what Allen draw have incomming power in first switch then go to next switch then go to the luminaire this is the easiest way to deal with it plus what more it will meet 2011 NEC code without issue at all espcally if you have electrionique timer etc.

Merci,
Marc
