200 A 3phase cutout bs88 fuses... manweb said they wouldnt connect the installed 95mm tails for the installed 100ma rcd for temporary site ofiices etc this supplies a large 3 phase board that currently supplies a smaller 3 phase board from 100 amp 3 phase mcb... If i installed the last 3 phase board and circuits from there and others installed the rcd, 1st 3 phase board and supply cable to our board would we be required to supply the certification for all etc? May not be very clear the way ive tried to describe... Also the issue with manweb saying they dont connect the tails in to there cutout and thqt we should? Cheers
