I had an inspector say that 4/0 cu was required for the SE conductors up the mast for a 200A 3Ø service. I've always used 3/0, which is good for 200A. He didn't actually talk to me but to the owner. The only thing I can think of is he is thinking the conductors need to be derated since there would be more than 3 CCC conductors in the mast/raceway. But I don't think the neutral would count as a CCC.
Thoughts?
