The normal way of providing 30mA protection in France is to fit at least 2 RCD's, one Type A for cookers/washing machines/motors and as many type AC's for the rest of the circuits.
From what I understand, Type A's have extra electronics to stop DC currents from saturating the detection coil (Thyristor controlled equipment being the man culprit)
Now I've got to put a RCD on the main supply (3 Phase) of a house so that it gets the 30mA protection
The normal way to do this is to fit a SINGLE type AC between the supply and the consumer unit.
(BTW. The consumer unit has over 30 circuits and no way of splitting then to isolate the above items)
The cost of a 3 phase Type AC is 261€ and a type A is 291€
Apart from the extra 30€ costs, it would seem to me, to be better to always fit a type A rather than a type AC
If fact, a singe phase type A's ones are only 5€ more, so why ever fit a AC when a A should be better
