Meter tails in ceiling ?

[Edders]

Hi all,

I am moving a CU from next to the meter to about 1.5 meters away on an adjacent wall. Am I OK to run the meter tails through the ceiling void between the joists (plasterboard ceiling) to the new CU position or is a case of installing an isolator and 25mm swa?

Many thanks

More info need to give an answer.
Will the tails be longer than 3m?
Will any part of the tails be in a wall at a depth of less than 50mm?

1.5 meters away

would be move then 1.5 meters from the what you are saying .

Personally I would be going with a switched fuse, this would allow for a point of isolation and afford the tails some protection rather than relying on the DNO fuse.

Dependant upon the installation method you might be fine with running the tails as they are if not either RCD or SWA.

Why 25mm swa?

Are the tails coming down the wall surface or buried to the new C.U position or is the C.U to be at high level?

The c.u will be at high level

No not more than 3 m, in the ceiling but then coming out at ceiling height into board at high ish level

That's what I'm asking, if its necessary or not.

Then I don't see any technical reason why you would need swa or a switch fuse.

Thank you for response, I just wasn't 100 per cent about the tails being in the ceiling. So as long as they are coming down the wall surface or are buried at more than 50mm in the wall then that's fine as well?

Unless the meter is already at a high level I find it hard to believe the tails will be 3m or less as I generally find - from external meter box to ceiling = 2.5m (includes 0.5m through cavity wall and in meter box)
In ceiling (from what I understand from your post = 1.5m
From ceiling to repositioned consumer unit 0.5m (min)
Total = 4.5m

As above, 3m of wire gets used up surprisingly quickly!

I would really check/measure the distances involved first. Have you got pictures and/or a drawing of the planned route?

Yes the meter is also at high level, but yes you're right I will double check the measurements its going to be close to 3m that's for sure

No pics sadly, but yes I will double check, its going to be close to the 3m for sure
