I can't see a problem with it especially if it's you operating it since you know where all the RCD's are and would check to see which one operated.
Yeah, I'm less concerned about working out which one went than any of them not going at all. Especially now our main CU is properly labelled and not "car port" and "east car park" (we have neither of those things).

I wish I could remember why the teacher had such a hard on about it. 'RCD Contention' is the term I think.
