my point entirely, thats why i asked him what earthing system he has, what size his tails are etc because from his info his main earth must be 10mmCan't use the adiabatic for a main protective bonding conductor has to be selected from 544 p134.
its a bit of a daft question really if its for an assessment, upgrade it to 10mm and get it to the correct position, no point setting yourself up for a fall
if i was your assessor i would be expecting 25mm tails (100A) 16mm earth and 10mm bonding, if not i would be looking very closely at all other areas
