Really went to town on this one, Crabtree metalclad board, and 14 (count them) RCBO's, the single MCB is for the armoured submain to the garage.
14 x RCBO Board.

Thats a lot neater than I got the wylex one I did like that! Though the fact that I was replacing serval boards and re-routing lots of circuits and had to get it powered up with 1/2 of the circuits in, and a temp feeder to an old board and then add the extended circuits the next day didn't help!
Boards are too small for all RCBO in my mind...

Looks a neat job apart from the functional earths. About time the manufacturers figured a way to take it direct from the DIN rail rather than having a flying lead, IMO. It's not at all uncommon with DIN rail mounting earth terminals.
That's a good idea.

I agree, more headroom is needed.
More and more RCBO's do not require a function earth.....Memshield3 being one of the them.
I would prefer to see a neutral rail similar to Merlin TP boards.

metal din rail, metal clip, use the clip for the functional earth.. not rocket science is it..?
neutral rail?
either double stacked terminals on the input ( like the output ), or an extra rail to clip into like on the square D ones..

Square D and Merlin have a neutral rail to connect to IF required, aswell as the usual Lives. Unfortunately this only works with DP two module RCBO's or MCB's
The functional earth has been ditched by MEM - I am sure others will follow.

All my board changes nowadays are all-RCBO, tend to opt for metalclad enclosures because they are much roomier, would be nice to see a neutral rail, i'm sure this could be done with the crabtree encapsulated bus system too.
If this system had DP RCBO's it would be as wide as a doorway!
Tried to get the functional earths neat, they were ok on the B types, but the C types have longer flying leads (and no 'this istallation is protected by rcd...) in with them, so it knackered it for me a bit. Ditch the functional earth, just like an RCCB is what I say.

Well, John, the neutral ends of the fly-leads are nicely formed, the ends of the functional earths have nice bootlace-crimps on (which I could replace myself) but i'm more concerned about warranty issues and if someone in the future wants to re-use or move an RCBO.
yes, I understand about the nice ends, and it is tiresome if you want to re-use a (fairly expensive) RCBO and find its leads have been cut annoyingly short; but IMO the Neutrals especially (even worse on the self-fit MEM PODS which have I think 6mm neutrals) are so long and thick that it is very difficult to install them neatly, even in a roomy enclosure, unless they are formed to a good shape and then trimmed. It is worse when you have to install a lot of them together.
the functional earths (if present) are so thin that they can be coiled up out of the way more easily.
BTW I think yours looks pretty neat

I always trim the fly leads if thats what it takes to get the job look neater, more so on re-fits as you tend to have a job lot of cables which are never in the right places. I wouldn't worry about the lead being to short for someone to retro-fit it, after all, what would you do? Im guessing you would just crimp it.
MEM pods are generally allowing for fitment in the larger 3 phase boards, hence the longer neutrals..
