coughed up some electrons that declared:

If you were to fill a large consumer unit with RCBOs, it looks to me
like you'd have trouble fitting all the wires in, let alone connect
the final circuits. Is there a knack to dealing with all the wiggly
blue wires, or a best practice? Alternatively is there a make of CU
that has more room inside?

I'm in the process of ordering a Hager industrial Type A metal board (like
this:

But the 20way version
)

It claims to be roomy. It's not an ugly board, but it's not very subtle
either - mine's getting a wiring cupboard built around it anyway.

I'll have mine in a couple of weeks - I can take photos if you can wait that
long.

Cheers
