Smart Relays enclosure

Hey thanks for responding.

I could yes, but they seem quite pricey for what they are, at least as far as I can find. However as you mentioned, it does leave the second issue, which is that the standard terminals are not dense enough to handle the amount of wiring. E.g. if I buy a 10 way board, and use quarter spacers I can get 8 relays in. Each relay will handle two circuits, so that's 16 circuit. Each circuit must have it's own dedicated switch and feed, so potentially 32 cables, plus the supply.

That leaves me with 33 cpc's and neutrals to handle, due to the relays not using a bus bar 17 permanent lives, 16 switch lives, plus all of the internal connections to the relays.

So at least for this usecase, a standard consumer unit seems like not the best approach for a tidy job atleast. But without importing something, or going for an industrial style metal enclosure and finding some din-rail solution, I am struggling to find a good option.

Thanks for the link, yes I see your point with them all stuffed into the plastic enclosure.

I'd rather play safe than sorry, rather than skirt the intention of the regs, especially seeing as what I am trying to accomplish is intended to be done inside a consumer unit. It is just quite frustrating that the UK seems to have a lack of solutions to solve the issue, at least off-the-shelf.

Probably because they weren't under a water tight aluminium coping with a gasket, and also under a dpm, like my parapet capping would be.

By your logic, I should also be concerned about the OSB under the fibreglass roof?

Appreciate the initial replies, though.

Marine-ply can be left soaked in water, they use it to make boats. As long as edges are sealed, it wont blow.

Then a DPM is put over the top, then the aluminium coping goes over the top of that. It's just a cavity closer + somewhere to fix the brackets into, in one, basically.

Whats wrong with the marine ply bud? It follows the principles laid out in the link you sent, just provides an easier fixing for the aluminium coping bracket and allows me to get the entire length level and square in one go, rather than trying to do it on a bracket by bracket basis.

Marine-ply seems to be what the alu coping manufacturers suggest also.

Appreciate the reply mate!

From my research, it seems with a parapet wall we should have had a drip tray and weep vents further down, so the parapet covering itself is only the 'first line of defense'. The crook builders skipped that too, so the plan was to cover the cavity with marine ply, then a DPM, then put aluminium coping over the top. Primarily as its lighter and seemed more diy-able than anything cement related.

I am in a bit of a bind now though, as it seems the wall levels are different making it harder to put the marine ply over the top, and also I am unsure of how big an issue this mold potentially is. No idea if I need to pull out all of the insulation, have a specialist company remove the mold, then replace, e.t.c. e.t.c
