XPS3 3-way wiring trouble.
« on: October 07, 2009, 11:37:23 PM »

So, I've installed a couple XPS3 as single-pole, and have had no troubles.  So, I ordered some more along with some XPSS to do some of the 3-ways in my house.

So far, there's always been a neutral wire in the box, ready to go, I figured 3 way wouldn't be a problem.

It appears from the wiring though that either I am misunderstanding the wiring, or the neutral wire is on the hot side, which means I can't X10 them?

Can someone with more knowledge than myself take a quick look at what's going on, and help me figure out what's going on here?  I'm rather confused by the white wire in the second box.  On the first box, it seems that the traveller wires are the pink and the black.  If thats the case, then on the other box, the switched leg would have to be white, which doesn't match any of the other wiring in my house... so I figure I must be reading this wrong, or its wired funky.  One would think that the travellers should be the white and pink, and the black should connect to the black in the first box (I'm assuming it's the switched leg to the lamp)



Thanks ahead of time.

The boxes with hot/neutral are big wirenuts with several other wires in it from the switches in the same gang.  I opened up another 3 way, and it was wired similiarly in that the hot wire was in the same box as the neutral, and the other box did not have a neutral. 

Can you wire the XPS3 the other way around with the hot/neutral being on the XPS3 side, and the leg being on the XPSS side?  If so, any changes to the wiring?

Yes White is not always Neutral. Many times a switch loop uses the white for other things. Though most times it is marked with a piece of Black tape.

You should be able to use the XPS3 where both the power and load are in the same box and the companion XPSS is in a box all by itself.

This is from the data you have posted.

If you are not confident or if this is unclear Don't do it!

Black from the Line Wirenut and the Black from the three wire cable to the XPS3 Line terminal
Pink (Red) from the three wire cable to the Control Terminal of the XPS3
Add a White wire from the Neutral wirenut to the XPS3 Neutral Terminal
Disconnect the Black from the two wire and the white from the three wire.
Tape up the White from the three wire as it is now not used.
The Black from the two wire now goes to the Load terminal of the XPS3

XPSS Companion end.
Black from three wire to Live XPSS Terminal
Pink (Red) from three wire to XPSS Switch Terminal
White from three wire tape up as you did with the other end.

If your XPS3 came with a single page installation sheet. There is a four page one available for download on the X10Pro web site. In the Installation Instructions Tab.
