Wow, I thank you for the infor ind the friendly? banter on this subject. I will check on cost for upgrading wire. The old panel is a Buldog and it states. 125v 2 wire, grounded neutral. I traced it back to the main panel and the 3rd stranded wire ( this is se cable) is attatched to the neutral bar.
One question is, why did not the electrician installing the new panel or the inspector, make mention that the old sub panel was, did not have a ground wire returning to the main panel?
Is it a case of, we'll let it go this time? and in the event so, why not allow a new subpanel be connected in the same dashion? I do see the value of a separate ground from the sub back to the main. Am I to understand that without a grounded subpanel, the breakers may not trip?
Thanks, keep up the banter.
