I don’t like that set up at all, 6mm cable should be protected by 32A protective device especially when you consider insulation factors, so from the utility meter what csa of tails/cable is selected 6mm? And what size supply cut out fuse is there? If it’s 60A needs to be 16mm if it’s 80/100A needs to be 25mm in my opinion. That diagram isn’t a British one is it?
Tails wouldn't necessarily need upgrading to 25mm.
