How to bodge up a deliberate mistake

Came across this while doing remedial work

 

[telectrix]

just trying to work out WTF is going on there.

Looks like bus bar cut too short on left and spare tail used to feed 6th MCB from left?

 

[telectrix]

but that 25mm? bit of tail is just linking 2 MCBs that have no L feed.

It loos like a dual-RCD board and someone wanted a single non-RCD MCB feed.

But it really begs the question "why?" as there are surprisingly few circuits for that size of CU and one wonderes what the 32A non-RCD feed with two cables was needed for.

Assuming it's a house, and those two are a RFC I still think someone ran out of bus bar or cut it wrong and this was their hack. Either way plenty of questions, as why not just swap an unused breaker.....

 

[timhoward]

UNLESS there is an earth fault on the RFC....
Also seem to be not enough neutrals conductors?

I'll go with the bus bar cut short.

Can a mistake be deliberate ? lol, I thought the whole reason we call them mistakes is because they are not intentionally done.
