    This is an easy one. There is essentially one major thing in NEC 250 that is completely wrong. You may find more but I stopped when I saw this one thing.

    This took longer than I thought it would. I kept wondering why we were upsizing one of the sets of feeders to 125 amps, and I couldn't understand.

    Sorry, I didn't finish my thought. NEC 250.24(A) requires the grounding electrode conductor to be connected to the grounded service conductor at the service, not in a sub-panel.
