I have a generator (Generac 22kw) installation coming up and was trying to size my conductors and raceway(s). Initially I was going to run separate conduits for power and the control wiring but I see that Generac now claims all the wiring can be run in the same raceway. I just happen to see a local inspector, not the same inspector on this job however, but he gave me thumbs up on pulling all the conductors together. My question is when it comes to derating these conductors, more importantly, exactly how many of these control wires are considered CC? According to their wiring diagram, there are six conductors, and just in case the homeowner wants to add an oil pan heater, I'll throw in another two conductors making it a total of 12 conductors. (Two ungrounded, one grounded, one EGC, two for the heater, six control) I wanted to pull #3 cu but I may have to bump it up.
For the heck of it, can I reduce the size of the neutral?
