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.

Electric Eagle,

This is an interesting one! I've installed a couple other manufacturers systems and not seen any hookups like this before.

This is the Master Dimmer[/i][/b]

[b][i]This is the Remote

Tech support at Genlyte says that the gray wire is only for the LED in the remote control. The LED is on only when the luminaire is off. Tech support says that the gray can be connected to either the EGC or the neutral. [Linked Image]

Note an alternate wiring method that caps off the gray is shown only on the bottom of the second page of the installation sheet for the Remote.


Apparently, UL has approved the use of the EGC for the return current off an LED nite lite (if the installer wants to hook it up that way).

I found it odd, but then again the groundwas used for the return on dryer lights up 'til a few years ago. It seemed to work just fine, so I guess a LED can't hurt much, what can it draw, .001 amps?

Sounds like an obvious thing to avoid on a GFCI protected circuit.

Just thinking out loud ...

Electric Eagle,
That looks like a really good dimmer system.
A lot easier to wire than some of the "telephone exchange" remote dimming systems, we have over here in NZ. [Linked Image]
