Is it possible to have a circuit feed both a lighting panel and a rooftop RTU? I have a set of 4/0's protected at 200amp from an MDP that is split in a j-box, the 4/0's continue to feed a lighting panel and a set of 3/0's goes up to a rooftop RTU. I don't have all the details of the rtu disco, fusing etc, but assuming they were all rated properly, is this installation possible? Is this considered a tap?
