Remember to tell us what the problem is/was when you find it.
I had one (intermittent tripping) last week, three hours it took to discover an external light switch buried in decking, soaking with condensation. Methodical often wins the day!

I presume it's a split load board, a crossed neutral would explain the wrong rcd tripping. The test button not working is odd, did it trip out on a 1/2 x IΔn test?

Checked the N connections all correct, button I think is what is throwing me of script indicitive of no current but clamp shows equal current in /out, no trip half test

A neutral earth fault can prevent the RCD test button tripping the RCD, see my and others previous posts. Don't ask me why, I'm not that clever, others might have the technical reason. From personal experience, but once experienced, its something you remember.

In the end it was a new LED hall light I put in before I took the old board out to give my self light to work as there was none there to begin with, I rigged it up from the henly blocks all kosher via a temp fcu,and it was the last thing into the board and this was causing the issue, as I said my plan was to remove the earths in turn till the tripping stopped and it was the culprit, what' the saying assume nothing suspect everything, well I assumed "cos its new it's ok" , all circuits test out great and as it is class 2 I disconnected the earth till scewjobs send a new one, cheers all for insisting I had a N..E fault
