18th edition consumer unit

[longers30]

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.

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

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.

Have you consulted the seal fairy??

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.

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.
