So in layman's terms "a whitewash"Thanks for suggestions. Am in the hospital today so haven't been able to do much more observations.
Murdoch (msg 42) not sure what you mean by "off", but all the internal units have been off for months, and tripping occurs frequently when they are not on.
Devon Chris (43) A/C circuits new and completely separate to everything else. HEating is via conventional boiler, underfloor heating radiators, thermostats, controllers etc. Only control for A/C are the buttons on the units and the remotes.
DPG (44) happy to install rcbo's if that's a solution. In fact discussed with previous electrician possibility of swapping whole CU to rcbo's.
Peter999 (45) as I recall original install only provided statement saying it had been checked and commissioned satisfactorily. Don't recall any technical data. I will recheck. When A/C engineers returned to investigate they left a document stating fault lay with dishwasher circuit.
Elsparko (46) I have been pointing this out to A/C company all along, but they don't appear interested.
Wilko (48) interesting point. There are local external isolation switches like your picture. Now I haven't tested recently but on one of the first occasions red tripped , I was away and my wife rang to say she couldn't reset the tripped rcd. I advised her to isolate using the external switch, and she confirmed she could then reset the rcd. I told the A/C company this in no uncertain terms and even provided their engineer with a written summary including this, but they didn't seem to think it mattered.
Lurch (49) obviously will get professional advice but happy to change some/any/all mcbs to rcbos if that provides a solution.
Murdoch (50) I don't know what a clamp meter is, but I would expect an electrician to have or obtain whatever is necessary?
Thanks again.

10 minutes ? I had to wait till morningA check on earth leakage is the way to go. You're going to be guessing otherwise. Check leakage on each air con unit.
Took me 10 minutes to type this as I have been drinking since 6pm. Bear with me if I don't make much sense.
