We recently had a designer spec out some fancy Lightolier dimmers. You have a main dimmer and as many remote locations as you want. Once you figure out how to wire them, they go in pretty easy and work great.

My question has to do with the remote units. They have 3 wires, black, yellow and gray. The black get a hot, the Yellow gets a traveller hooked to the traveller on the dimmer and the gray get put with the grounding conductor and the ground for the control. It seems to me that this is being used as a neutral and therefore shouldn't be with the grounds. Anybody know how this is OK. They are UL listed.

A tip for anyone that ever has to put these in, make sure your taps are made to have switched and fed at one location, then use one traveler to feed a hot to all remote locations. Standard 3 way taps will have to be remade.
