Mains cable to consumer unit top floor flat

So what is the problem?

So what is the problem?

The distribution circuit is not compliant t&e not protected IMO this should be a departure. If that the supply cable shouldn't stop anyone rewiring the flat.

Isn't protected by what, a 30ma RCD?
Not going to be part of the job if you are rewiring the flat.

Yes no RCD protection

Do I fit a small board at the main incoming downstairs and protect the cable with a time delayed RCD?

What would the RCD be for? Is it a TT system?

 

[westward10]

Yes no RCD protection

Submain is fine so needn't be included in the installation.

sub main looks like it will need Rcd protection, the other issue is the size of the cpc which will be ok if MBPC are not required at the Flat.

The only reason it may need rcd protection is if it’s buried <50mm inside the other flats, and we don’t have that information.

It’s no different than regular meter tails in terms of mechanical protection… it’s just a long length, which is taken care of by the 60A fuse.

OP - is this T&E run on the surface or in conduit all the way? Or is any of it below the surface?

I'm guessing not as you were talking about changing the cable or adding RCD protection.
