Electrical certificate?

[binky]

Thanks, I do see the danger of that now. Is this the same for the rcbo that has just been fitted. Page 2

No, looks like he's direct fed that from the main switch, can't really see from the pictures on my phone. Rough either way.

Is it dangerous? thats my main concern.

Yes it is potentially dangerous in my opinion.

Probably looks worse than it is, he could have rearranged the board to fit the RCBO next to the main switch, and been compliant with manufacturers instructions for use of their products. Chucking bits of cable in where busbars belong is not compliant.

To avoid any such nonsense I usually install a separate mini board tapped into the meter tails. It's easier than altering an existing board and ensures full compliance with today's regs ( and avoids any issues with existing installation).

And fitted correct rcbo, he fitted an ac type b curve so no dc protection

 

[Fleeting]

Consumer unit should have been replaced preferably not by these people.

DC protection is built in to the inverter, RCD protection is usually built in too, unless it's a really cheap and nasty unit. You don't really need RCD for solar work unless someone decides it's a good idea to channel the cables into a wall and plaster over them. It's a fixed piece of electrical kit, it's not like you are going to plug your lawn mower into it whilst standing in a paddling pool in the garden...

But surely should be type A rcbo apparently ac should not be fitted after 27th Sep 22

It doesn't need any RCD, the fact they fitted one displays further ignorance

He didn't fit rcd all he did was fit the rcbo.

 

[Murdoch]

He didn't fit rcd all he did was fit the rcbo.

a rcbo is effectively a MCB with a rcd built in

as binky says, it doesn’t have to have RCD protection

 

[binky]

Same thing, RCBO is an RCD and MCB combined into a single unit. But as I said before solar inverters have such protection built in, and monitor the AC supply, so you don't need additional protection for the circuit, just a MCB or other suitable overcurrent protection device. Could use rewirable fuse if he liked, (but not in that board )

 

[truffle pig]

He might have put RCD/RCBO due to the supply characteristic could be a TT system? MK only do an AC type to fit that board.
As Binky said, a separate board would have been the best option IMO

 

[Murdoch]

Are you sure about that?

This is an A type, same dimensions and technical spec as the ac one

I think you will find that the MK A type RCBO doesn't line up with the old busbar (part number ends in an S).
