Dual rcds tripping

[HandySparks]

Where are the under unit lights switched from? I had a similar problem once . They picked the live from the kitchen switch and a neutral from a kitchen socket.

Here's exactly this situation I found a couple of years ago. Neutral borrowed from the oven circuit:

thinking even further in front / I like it
But make sure you have a lighter or matches in case it is an electric ignitor

Yeah most of my regular customers bring me a fresh brew every hour or so.
The one's that are out all day say "help yourself to tea and buscuits" and buy in extra tea bags.

Evening gents bit of advice required please I have recently finished a partial rewire (upstairs sockets upstairs lights and smokes). All is fine apart from when I turned under unit lights on in kitchen it tripped both rcds. There is 1 2 gang switch in kitchen 1 for main kitchen light and 1 for under unit I have taken link out from main light switch the under unit light switch and this rectified the problem no tripping but when I put link back in both tripped again and ideas guys cheers by the way pretty new to the game so be nice 

I'm curious how you located this. That said you say it stopped the tripping, but what isn't working now?

Morning gents had a look and there is a borrowed neutral from socket in kitchen also IR reading for neutral to earth is reading at 154 M ohms could this be due to the borrowed neutral ?? Thanks for advice as we'll guys cheers

So the supply for your undercupboard lights should be fused down from the sockets and the line from the fused down sockets goes to the switch for the undercupboard lights and you are sorted.
Alternatively get a neutral from the kitchen lights to supply the undercupboard lights and leave the switch as it is.
154Mohm is fine.
