Thanks for everyones input, the things you have mentioned I am aware of from code digging and/or from installing lots of SS hoffman panels and gutters. I guess I was just looking to see why we would have a code article like 409 which to me is to prohibit homemade boxes and yet nothing on raceways that are homemade.
In Western Ks. the AHJ does not do inspections outside of the city unless that county requires code inspections and those are few between. Other wise it is up to the contractor to inform the customer of NEC requirements or the company to tell the contractor what they want put in. And this seems to leave some things open to opinion like earydean sort of mentioned.
I might be way out in left field but the code is for safety of person and equipment from fire and shock.
