[QUOTE="SPECIAL LOCATION, post: 552049, member: 250"] You may have two broken earth connections if the utility sockets were meant to be a ring? I would start be establishing exactly how the circuit is wired... a few dead tests with a good continuity meter wouldn't take too long.. Once you know how it is wired that should help in establishing at which point (or points) the earth is disconnected! Once you have got your earths reconnected / replaced, you then also need to confirm that the earth loop impedance values are correct for the type of MCB / Fuse fitted? [/QUOTE]
