Hello,
New to the website here. I have a question about subpanels; I understand that they are supposed to have a separate four wire feed, and are not supposed to have the neutral and ground bars bonded. My question is, I have seen a few instances where 3 wires (hot+hot+neutral...no ground) were ran to a detached structure, and a ground rod was driven at this separate structure. In the panels the neutral and ground bars were bonded together. What exactly is dangerous about this situation?
Thanks.
