I have been asked to install a few small, lightweight LED par cans in a local venue. I have done this many times and in the past have been able to run the cabling outside of the walls, hidden behind beams, architectural elements etc. This time the cabling (power and DMX) need to be run through the walls and ceiling. I am not a licensed electrician, therefore the venue has offered to have their own in-house engineers/electricians do the snaking as long as I mount the fixtures and provide the cabling.
My question: In NYC, are there codes that specify the type of cabling required to run through the walls? My understanding is that there will be no conduit run here, as the distance from fixture to fixture is only a couple of feet. Do the cables need to be fire-retardant or made or a specific material to be safe and up to code? If so, what are some recommended manufacturers/links for the appropriate cabling.
