Hi All
just done a c/u change fitted with 8 RCBO's and when testing the trip times 2 of the RCBO times were too high (40a 30ma =40.8 ms . 32a 30ma = >40 ms )on X5 ? changed the 2 x trips and retest exactly the same times ?! disconnect the circuits and retest trip times perfect, ok so retest circuits all ok ??! phone control gear and speak to tech it could be the cooker hood (double insulated ) or the w/machine, they don't like them. in my case it was the (40a) electronic shower (32a) combi boiler .
just letting you know
