[QUOTE="jimmybobbob, post: 395049, member: 26091"] Andy tm My thoughts ARE that the rcd is protecting the supply cable going to the house AND the nature of the installation ie stable block so protecting any livestock....rather than coming up with the SAME answers as other posts. Im thinking that he was also covering his own back also from the shoddy electrics that had been previously installed (although am I right in thinking you are responsible ((as a skilled operative)) for what you connect and energies) The rcd isn't type s and there is a PME earth terminal that was/is being used as means of an earth path as apposed to a rod so TT is ruled out I'm affaid. Apprentice87 you are right in thinking that the 16mm earth was used as a bonding conductor as the oil line was buried, as was the water (although a plastic pipe) If it is to be guaranteed that every metallic part of the installation is bonded (even the DB itself obviously) then still the need for the RCD is surely dismissed (although as I,ME,MYSELF already assumed he was thinking of the nature of the installation, ie lifestock and buried cables etc) #Andy tm [/QUOTE]
