I've posted this a few times and this is at a mates house following a kitchen refirb several yrs ago. :omg_smile:

Correct

It is fed from a 32a MCB in the main CU but this is where the right way of doing it stops.
Live is then fed to the far right 32a MCB in this board, with a link back to the RCD, the neutral is direct to the RCD. And every circuit is fed upside down.

Impressive to get it that wrong. ?
I think that's the best one yet or at least for a long while.
That would have made an excellent game of "find the incoming supply". May I steal this photo for training purposes?!
I'd found the live, but still can't totally fathom the Neutral as it looks like the bottom left of the RCD goes straight to the N bar....
 
My first words when I opened it up where ‘what the actual F!’

Of course, feel free.

I haven't touched that board yet. I've got to go back later in the week. So will fathom out how it is wired.

Property has 2 CU's. Both have 10 circuits. All 20 circuits are not labelled. So I spent 5hrs yesterday playing my favourite game of hunt the circuit for the first CU. Only reason I had the cover off was to see which MCB from the main CU fed that one.
 
I can't make any sense of that

Looks like the outgoing side is supplying the incoming side of RCD
I think I've got it...it only makes sense if there's a break in the bus bar behind the mortar though.
Otherwise the RCD would trip if the far right breaker that reverse feeds the non-protected half was on.
Special!

I reckon it's someone from Europe - over there you feed the tops and the load comes out the bottom.
I have it on good authority from both Legrand and Hager that their MCB's can be used in both directions.

Looking at the gap between the two MCB's below the mortar snot, it would seem the busbar is not continuous as suggested by Tim.

Yeah, new CU. The other immediate thought is max demand / upstream protection given ?6mm incoming conductors. Hope it's SWA. Also might be a 2.5mm in a B32. Anyway, lots to investigate!

I think a new board is a bit extreme, especially if it's not damaged, (can't see the lid) Legrand is a very good quality product, re-wiring of the board is possibly all that is needed.

As a secondary board does it need a main switch, if all the circuits are protected by an RCD? Certainly in Europe the main board would cover that, it is now a requirement not to have a secondary board supplied from an RCD, but from a cut out switch and an RCD in the secondary board.
