Not an electrician (hey, stop that razzing, now) and don't do any wiring but have really learned a great deal here. I just keep quiet and learn. I just like to know what's going on in the other trades around me. Can someone give me a short, layman's explanation of what was going on here? Why 66.5 volts through a waterline? Partial ground/bond? I always like to be able to speak in a halfway knowledgable fashion to other tradesmen, so...? By the way, I found you guys via the safety portion of the site which is excellent.
