Cable sizes

Not without the neutral conductor having overcurrent protection which disconnects the associated line (phase) conductor(s).

I think you have missed the point.

I think you have missed the point.

I definitely haven't.

 

[EFLImpudence]

I definitely haven't.

So - 60A fuse, 25mm² Line conductor, 10mm² Neutral conductor. Satisfactory?

Non-compliant.

I have seen loads of imperial DNO supplies that are the equivalent of 10 milli on 80A fuses.

Non-compliant.

Non-complaint with what? As has been said, DNOs and suppliers appear to work to regulations/practices other than BS7671 and, as has also been said, 10mm² cables on 60A, and even 80A, DNO fuses appear to be compliant with those regs/practices.

Indeed so. Even in my pretty limited experience, I've also seen a good few examples - particularly with 60A fuses, but sometimes 80A ones.

Kind Regards, John

We're talking about the outgoing cables from the meter which aren't the DNO's.

Forget the "We're". That may be what you are talking about, but, as for the rest of us ...

The cables that run from the network providers fuse to my meter are 10mm diameter for the live and 6.5mm for the neutral as measured with a vernier calliper (not sure what that is in X sectional area).

Non-compliant.

How is it non-compliant?
