EICR in Flat - cross-connected circuits, T&E tails, composite earth

Just want to query this Dave. My understanding was that the earthing conductor for standard domestic PME was a minimum 10mm, based on the requirements for bonding conductors for PME installations, table 54.8. Is the 16mm necessary if adiabatic will allow 10mm?

You are probably right, but for some reason I have it stuck in my head that the earthing conductor needs to be 16mm with PME.
But it has been a good few years since I had anything to do with domestic and smaller supplies.

In the 80's I was taught that with PME earthing arrangements we used 16mm for the main earthing conductor, some went a bit crazy and were bonding gas, water, even cross bonding with 16mm.
