The old code was that each outbuilding sub panel was considered a separate electrical service. My wood shed is wired with a separate ground. The well pump was once wired with a separate ground, but the old underground feeder died and I'm running a new service from the shop.I'd agree with you on the NEC and grounding, but that's probably a sit around the stove and chat all winter item.
I'm not an NEC expert, but always happy to learn. Is that rule for sub panels in the same building? I.e. a well pump panel would be a different building, and therefore need a ground? (What is the section, or sections, that apply for that?)
All the best,
Peter
