PME Supply Advice

[bilbo_88]

Afternoon All,

Just pricing up a job and thought I'd pick your brains.

Quick run-down, Block of Flats with an underground car park. In the mains room each individual flat has a supply ran up to the flat (picture for reference) with a split concentric. The PME connection is provided within the flat via a connection at a Solid Link Fuse (typical house service fuse block) via the N.

So I need to install a sub mains next to the fuse in the mains cupboard (downstairs) supplying a socket for a hybrid car within the underground car park. My question is can I supply the submains with a TNCS supply via the Henley Block or a link within the Consumer Unit itself, or will I have to contact the DNO directly to provide me with a connection? Not something I have had to deal with before. I have noticed that other contractors have done the same but was unsure if it is the correct way to do it.

Thanks!

Yes but the problem is there is no connection to earth available at the intake.

Correct, there must be earth's on the ground floor, I hate when Peaple only show half a pic, how is this to be done.

It does seem unusual to not have an earth terminal at the intake to the building. How is the main bonding done?

There is an Earth Bar in another mains room, approx. 20m away next to the Ryefield Board that supplies each of these meters
