But I typed slowly enough for you to be able to slip in your edit without it showing .... unfortunately for you, the pre-edit quote was already in my reply by thenYeah, I'm not sure where I got that idea from, either.

JohnW2, yes that is how i test for it, lamps in, swithes on, test betweeen opposing L and N for continuity.
Well, at risk of upsetting some of those who proposed various 'interesting' methods (none of which I think would have worked), dare I suggest that if one wants to know whether the path from L through lamps is ending up connected at the wrong N, the obvious thing to do would seem to be to simply test whether the path from L through lamps is ending up at the wrong N
- which is what you and I would do.I also think there may be some confusion in some people's minds between 'borrowed' (wrong circuit) and 'shared' (linked) neutrals. Both can occur, both can (usually will) result in RCD tripping unless both circuits are served by the same RCD and both would be detected by 'our' method. The borrowed neutral is, however, easily the more common.
Kind Regards, John.
