[QUOTE="Bob Minchin, post: 551632, member: 37123"] A friend has just contacted me say that he woke to find his domestic circuits were "dead". Once reset, one appliance was showing an overvoltage indication and several white goods and hifi were damaged/non functional. He measured 378 volts live to neutral. Turned out that that there was a break in the neutral connection underground. I've heard that some of the latest installations include an SPD but looking at photos these don't seem man enough to rupture a 100amp board fuse so would one of these protected his equipment in any way? If not what precaution measure can be fitted to a domestic installation to protect against continuous overvoltage casued by such a fault. Bob [/QUOTE]
