Hello I am new here starting a new project,
I am designing a unistrut lighting grid in side a recording studio. Why Unistrut? Because I like working with it. This will be my third light grid. The first one I did'nt know much. The second I knew a more "got my white card" but still not what I would do now. The Third well we shall see.
The room is 50 x 40 x 12 blank dry wall. I plan on installing 1/2 depth size unistuit to ceiling in a non-symmetrical grid pattern per my lighting and set requirements. Industrial open look is fine here. I plan on bolting outlet boxes (4 square 4 x 4 x2) direct to grid spring nuts. All 3/4" Emt connecting with a max of 9 #12 conductors per pipe. Or really 4x 20 amp circuits per pipe. I understand normally a clamp would be with in 3 feet of box but what if my strut is 6 feet apart and I am hitting it like a T seems a shame to install a whole piece of strut thats only purpose is to clamp a pipe 3 feet from box, now if I run the pipe on top of strut parallel as it were it would cover whole strut slot so thats not good. Any ways my lights will be on threaded rod about two to 3 feet with a saftey cable in case it come lose. I am not planing on installing pipes to hang lights on, direct from slot threaded rod to light. Plugged in a max 6 feet away.
The grid will all coverage on a hoffman wiring tray (pending if I have to derate raceway)out side ceiling from there to 24 switchs from 12 breakers on a 60amp 3 phase subpanel in new production control room. All lighting will be LED. So though I have 12 circuits the load on any one will be low.
I am a electrician though not always active per "white card status" as that requires liability insurance per projects. I may have to reactivated for this project, though I am employee of company and they have insurance and this is warehouse remodel. The old inspector just said prove your Libility and we will rectave you years ago, not sure if I can roll in with company insurance or not, its all rather confusing, but Quincy is known or was know for a notoriously hard test I had to take it multiple time NOT wanting to do that again.
So what do you think? Just wanting to talk about it. Really on the clamping with uni-strut and the Hofman max wires.
