Does anyone have experience of neutral/earth faults and how you found it?

Hi, i am experianced at finding faults so may be able to help with some more info, earthing arrangement problem etc.

are you talking wiring faults or installations with appliances causing faults etc.

if to do with wiring you often find a neatral in a metal box been caught by a screw or something, and at ceiling roses a screw that caught the lampholder neutral connection on the 2nd fix stage, lots of posibilities, chase that fault with a megger!! i love fault finding find it much more interesting than the other mondane electrics!

This has the possibility of turning into a very long thread.

If it does end up a very long thread it's your own fault!!

Have you isolated which circuit has the neutral to earth fault yet, thats the starting point.

split each neutral in turn from the neutral bar and IR test it to the earth bar.

Once you have found the circuit, walk to the middle of the circuit (or where you think it is) Split the neutral (lets say its a a ceiling rose) and IR test each one to earth. You find the half of the circuit the fault is in, then just keep splitting down. This is the 'split half' tecnique, i have used it extensively with large machine control circuits

The spit method is about he best way, anything else is hit and miss guesswork !

It is the only reliable method for accurate fault finding.
