how to deal with a borrowed neutral

[TeeJay711]

The RCD trips when either the down or up switch for the stairs lighting is pressed.

. I think the circuit is wired from the bottom switch to the top switch, then to the up stairs light....no neutrals in sight, so i suspect the neutral is from the up light circuit. but the live an earth is from the down light circuit...

Borrowed neutral!!!!

What would be the recommended way to put the neutrals right?

Do yourself a favour and go to the diy section.

So how did you verify that there is a borrowed neutral ?

If it is as you say you will either need to run a new neutral up to the light or run a new feed down to the first switch (Tels method).

In either case you will have either a spare neutral or live in need of terminal - ruff......

You could, of course, rewire it properly.....

usually find that the L feed is just a link off the hall switch in a 2 gang config. so just remove the link.
