No power to any circuit

[Leejohnson222]

Please don't all kill me here but,

I replaced 3 lights tested those 3 and all working. Went to do a 4th a restored power and now the rcd trips.
Put everything back to how it was and no power to any outgoing circuits but all circuits have 240v.
No tripping at all unless I put in a plug top tester and the rcd goes
Split board 2 rcds, this is a job for a friend who won't be friends with me much longer.

I assumed if I remove lighting circuit (l, n, e)
that I worked on that would restore power to all other circuits but the problem remained
Any ideas?

are youse sure there isn't an isolator before the CU that's turned off? if the CU RCDs won't trip with the test buttonm then there's no power to them. lost N ???

Really appreciate all the advice, I went back with a more logical approach and tested everything, tails all good but no neutral when the main switch was on.
Replaced main dist board switch and all back on, I think I lost a bit of common sense and it was late in the day.
Glad it's resolved just weird how a lighting fault came up then the main switch failed.

Glad you got it sorted. Yes, that is a rather horrible coincidence!
