Hi everyone.
I'll be ringing tech support in the morning but i cant wait for an explanation.
I've just fitted a split load CU where there was once an old rewireable wylex fuseboard. Circuits to be fitted on the RCD side of the new board all tested fine. Insulation Res good, r1r2 good, polarity good. However, RCD trips whenever any load is introduced on any of the circuits on the RCD side. As soon as the shower is switched on - trips. Anything pluged in and switched on - trips. Cooker switched on (on RCD side cos of the socket) - trips.
I thought it may be a dufff RCD. Ramp tested it and it tripped at 17mA (30mA RCD). That is a little low i thought so changed it for another. Again the same problem - constant tripping.
What could be the possible cause of this. Could I have 2 duff RCD's?
Thanks
