18th edition consumer unit

[Midwest]

And I generally space the board off a little with a couple of pieces of small batten the same height as the board to facilitate this.

I do rather hate mixing pieces of organic matter with metal. Just doesn't seem very karma to me. What about plastic, or even some manufactures spacers.

Nah I like my little battens.

I like batten berg.

I bloody hate people who do rewires and still put the new board back at ceiling height....especially when its in the smallest cupboard they can find....even more infuriating to finallt get the cover off to find a birds nest

Hey all,

I have just finished a rewire of a 1 bed house and just have the board left to install. I am a qualified sparky but now work as a project manger so haven’t carried out much domestic work in the last couple of years. I know that the requirements for installing consumer units has now changed and am wondering what are the requirements with regard to cable entries into the board. I have the cables all dropping down from the ceiling where the existing board and meter position is in the entrance hall. Any advice would be appreciated.

I think you must do short course called part p etc ???

Thanks for all the replies. Looks like back entry will be the best way to go.
On a side note I’ve seen online that suppliers are selling the semi blind grommets which it says are ip66 rated for use on cu’s. Would these comply with the new regs as I haven’t seen this method shown anywhere?

Cheers

I assume the new board can be fitted to the existing wooden board behind also?

Why wouldn't it ?

Not sure thought I read something about it but I must be thinking of something else
Last point the existing tails are 16mm which will be fine as there will be little load being used. Anyone know how much roughly the DNO charge for coming out to pull the main fuse and back to reinstate supply after? It’s wpd here.

The new Regs apply to the CU, not the cable entry points.
You only need IP4X/IPXXD on the top and IP2X/IPXXB on all the other sides.
Use IP66 grommets if you want, but there’s no requirement to do so.

The seal fairy lol? Would that be the supplier? ‍

No, it’s the fairy that comes around and removes the seals before you get there.
Seems to be quite common.

Ah I see lol I know we used to do that when I worked doing house bashing full time but didn’t know if they had clamped down on it now.

 

[Dave OCD]

I haven't seem any clamping down, it's a miraculous coincidence I know but everywhere I do CU changes it seems the seal fairy has nipped in unseen just ahead of me.

Yes very strange, must be clairvoyant Fairies Mate,

If the seal fairy has been before you get there, don’t get complacent with the neutral, he’s got a few tricks in his sleeve too.
