![]() Upstream of the consumer unit, the neutral is almost certainly connected to earth. Then you need to replace that piece of cable.ĭefcribed wrote:Thing is though, even with freeing these up - making sure they're not earthing - I'm still seeing zero resistance twixt neutral and earth on the multimeter. At some point, you will find either a stray wire, or a screw that's gone through some insulation or (worst case) a cable run that's got an earth-to-neutral short in it. If all is well in that box, remake the connections and move on downstream. The likelihood is that you'll find a cover screw on a box has cut through the neutral wire, in which case a suitable piece of insulting tape will fix it. Start at one end (either will do): open and check nothing in there is live, disconnect the connections of the offending circuit, and measure to see which wire has the short circuit from neutral to earth. You work round the points/boxes etc in that circuit one at a time. All you need is a test meter, a neon screwdriver, and some patience. What is the function of that circuit? Does it feed a ringmain, or a single point (cooker) or a lighting circuit? In every case, you should be able to open the wall box, switch box, wall or ceiling fittings (or whatever) to trace the fault. A sparky would love the opportunity to rewire a whole house if business is a bit slack. ![]() I wouldn't employ a sparky to fix it, but it's not something for everyone to do. ![]()
