This is where I get my balls busted on this forum, I think the 6mm2 earth wire in the 16mm2 T&E is not adequate regardless of the adiabatic equation, thats if it does actually pass which I doubt,There is a thing as good practice in my view and rollocks to the regs, seriously rollocks to it, I always run a 10mm2 earth wire with a 16mm2 Twin and Earth for the main supply to a flat and usually connect it via a KMF switch via an 80 amp max fuse, a 60 even better if there is minimal load, you get slated on here for suggesting running earths with sub-mains haha, but I have always done it this way and always will.
I dont understand why you should get slated for running additional earth conductors with your submains. nothing wrong with going over the top, belt and braces as we say in yorkshire.
In almost all cases of industrial electrical cabinets i have worked in, have had a nice big juicy separate earthing conductor run into them, so why not flats and houses?
