I have just installed the 12v network with the heatmiser uh1 manifolds and all is fine, the switch line which goes back to the plant room to my heating controls wiring centre is all working fine, pumps are coming on, valves are working and boiler is firing. That's all good but however initially...
120meg ohm?? If so then its fine your allowed 2 ... It's just people have a tendency to write +200meg ohm on the test sheet and people get led to believe that's the minimum.. I'd happily put my tongue on the insulation with that much resistance mate :)

good luck

Yeah that's odd would have thought the rcbo would have seen the imbalance in current they are normally quite good :s dodgy rcbo by sounds of things but you say you trip tested it and it tripped in
Good time ok?.. Sure there will be a lot smarter guy to give a better explanation I'm sure.
