[QUOTE="apprentice87, post: 392793, member: 13534"] Hi Paul, Yes "fail safe" is what is required. I think it boils down to FMEA analysis as to figure out the effects of a fault if one were to occur. To go back the the "3 meter" rule, as it involves extra mechanical protection, at a guess i would think that the "extra intent" was aimed at TT systems, in that if you DID have an earth fault along the course of the 3 meters, you would be liable to have some VERY live exposed conductive parts.... john...
