Your opinion on the safety and legality of this board please.

This is looking more and more like an exam question

The busbar is connected to neutral at the RCCB. It's reversed polarity.

I believe that is just an artefact of the camera FOV..

I'm not so sure about that. The photo is taken at a a very odd angle (look at the relationship between busbat lugs and MCBs as one moves across), leading to some potenetial 'optical illusions'.

It looks to be as if the busbar is quite probably going to the '2' terminal of the RCCB, the big blue cable to the N of the RCCB and the big brown one going to some device to the right of the RCCB which we can't see.

Indeed, as I was writing whilst you posted that

 

[sparkwright]

Fair enough - I think you're right.

The Busbar certainly needs to be checked, looking at the part on the left it doesn't even look like two of those circuits are even supplied. Not sure what it's been cut with, certainly not a sharp hacksaw or something suitable.

I hate seeing exposed copper busbar like that makes me shudder.

I would prefer to see another photo taken further back

(Edit, just realised the bar is doubled up there)

I'm more concerned about the 2 on the right, it looks like the prongs may have missed the clamps.

 

[SUNRAY]

Second thoughts, I can't remember if BG have cage clamps or screwclamps.

 

[chivers67]

Indeed, it is a little strange that the MCBs are slightly smaller than the RCDS. Hopefully the prongs are long enough!

That is standard in the range.

It's impossible to be certain of anything from that photo, but it looks as if the busbar prong is in line with the blue neutral cable - and if the prong had missed the clamp, where else could it be going?

Indeed. Are the RCDs actually BG ones, I wonder?

Do you think it's not this

 

[SUNRAY]

Yes I believe they are.

Do you think it's not this ...

That's what I said, in prose, in post #18
