[QUOTE="Phoenix, post: 442478, member: 8133"] Cat amongst pidgeons.... Is a PNB setup TN-C-S at all? Is it not TN-S? Afterall N & E are separate after the point at which the LV electrode is attached.... does the fact that that this happens the other side of the wall in the customers switch board, rather than in in the transformer room with a DNO open fuseboard change much.... It certainly doesn't have the disavantages generally found with TNCS supplies and if TNCS is disallowed because of these, then considering the PNB set up being TNCS might cuase problems [/QUOTE]
