Gas meter move - earth

[stupot76]

Hi All,

Firstly apologies that this isn't really a DIY question - I'm just wanting to check on something.

Our gas meter has just been moved to an external meter box (attached to the house wall) and we have been told we'll need to have an earth cable running from the new meter position back to the cupboard under the stairs where the old meter was.

Is this the only way to do it? I'm quite keen to avoid this given that we'll end up with earth cable running through 3 rooms between new and old positions.

Any thoughts very much appreciated.

Cheers,
Stuart

You should have a main protective bonding conductor linking from within 600mm of where the gas pipework enters the house - before any tees in the pipework to your main earthing terminal usually located by the electric meter or consumer unit.
You should also have similar for the water unless it is a plastic pipe installation.

That answers my question - I need an earth cable going all the way through the house to the cupboard under the stairs - what a pain!

Never mind, eh!

What is your electricity supply type and how long will the main protective bond run be?

Will need to check on earthing arrangement when I get home. Fairly confident that it's TN-S, though.

The run will be about 8-10 metres from the gas pipe entry point to the main earth.

Thanks for your help.

If it is TN-S then 10mm is the normal size to use.
Can you upload a piccy of the distribution board cutout and surrounding wiring?

Thanks a lot.

I think I'll get a pro to do the job - so I'd better not "waste" any more of your time.

Thanks very much for your help - been really useful.
