Testing for borrowed neutrals?

[LittleHelper]

How would i test for borrowed neutrals?
Would it be a case of disconnecting all circuits neutrals at the DB and doing a continuity test between each neutral and seeing if any two circuits bell out?

hope it makes sense and i appreciate any feedback
cheers

close. you should IR test between neutrals, not continuity.

yes that would be a simple way to do it, have you got an rd not holding in

Cheers guys for response.
No stuart i havent got a particular problem at hand just trying to gain a bit of knowledge. Its one of those things you should identify as a tester before it makes itself apparent after a board change lol saves agro.

Teletrix, I guess my test result if a borrowed neutral was the case would show a dead short!

on an IR test you'd get a reading of 0.00 Mohms
