Dimming LED high bays...electrical newbie

[dave*99]

Thanks, Dave*99. So, 1-red and black for the 120V on-off function, green to gnd , then run the low voltage pink and purple to the dimmer wires at each fixture? The only other thing, will be is to find a dimmer switch able to handle the wattage of all the lights, which is just under 1100w total

Yes and check the 0-10V capability too. Dimmers need to sink current and they have a limit.

Looks like I'll have to spread the load over 2 switches. Just have to re-route 1, 14-2 and split the load. Didn't realize the load figured to 12.8A, on a 15A circuit, but I already had a spare circuit to the ceiling. Best to do this now as I'm ready to insulate that part of the attic. I'l have to contact Lithonia tomorrow as I don't see a spec for sinking current on anything concerning the fixtures. As stated before, only the hi-bays will have dimming, as the 8-4' fixtures have individual switches I can shut off whenever I'm not in that part of the shop. Thanks, again dave*99.

If you only have 6 fixtures the capacity of the 0-10v dimming will be adequate. But as you said using 2 circuits will only put 3 lights on each dimmer.
