[QUOTE="kme, post: 255045, member: 113"] 1. We don`t have more coming out - I can`t measure all cables; but there is at least 28A of returning earth current to the main panel- - I`m trying to find out where from! Most of the supplies that leave are SWA. 2. The SWA`s in question are (correctly) terminated through the roof of the panel - so not an eddy per se ; but there may be a circulatory effect causing some compound issue - good thought. 3. I`m 99% sure the earths are just that. Being TN-C-S, and unable to isolate makes testing the hypothesis rather difficult though keep it up - this is all helpful. When you`ve discounted everything else, you`ll have something left over which must be the root cause (blatant paraphrase of A.C.Doyle) [/QUOTE]
