Came across an 1-1/2 emt that feed out to the 4 rooftop units. It had 4 3pole 30A ckts in it. In all 13 #10 conductors counting the ground. None of the conduit is on the roof so temperature really isnt an issue. I was wondering if this was a legit install though. Doesnt some sort of derating come into play? Also do the 3 phases per fan count as one circuit or is each phase its own circuit?
