Some people I know have just taken over a building which has been converted to offices. They say their power goes off randomly when they have their computers running (about 12 of them) and usually the power goes off when they run the hot water and the boiler fires up. Upon looking around I found the modern twin rcd c/unit is fed by a 16mm t/e from the meter on the floor below, this sub-main has a 30m/a rcd and a 40 amp mcb feeding it. The people there said it's always that rcd that trips out, not surprising of course. My point is that they tell me they had an electrician in the other day who changed that rcd because it was only a 40 amp one so he replaced it with an 80 amp one, still only 30 m/a though!
I'm going back there tomorrow and was going to fit a 100m/a rcd but thinking about it there's no need for the sub-main to be rcd protected anyway because it's not concealed in the wall anywhere.
