Split MCBs on consumer unit

[Mazak]

Hi all.
How would you split MCBs where there are two ring final circuits (so better separate them). There is one electrical shower (will be on 40A).
Any ideas?
TNS system.

Oh didn’t realize it was down to the customers to do the design..
I can rip out that whole new section on SPDs

 

[Mazak]

I forgot to add that there is only one circuit for lightning.

Id RCBO the lighting then 100 percent

 

[Mazak]

I forgot to add that there is only one circuit for lightning. So that is why I would do like on photo.

 

[ChrisElectrical88]

As above, RCBO for the lighting as a minimum.

 

[Mazak]

Also MK are dog shyte mains boards, get a hager for the same price and thank me later.

Wheres the SPD?

Yeah , another advice on topic ))

There is no RCBO , why would I put RCBO like I have MCB 6 A for light.

 

[Mazak]

does it not come complete with metal backing or is the wood the back box like the old wylex consumer units .

I took it out for a reason. It's on my floor

If you dont like when i go slightly off topic dobt read it, i was asking where the SPD is, its relevent to the work your doing.

The RCBO is common sense if the house only has 1 lighting circuit to cause minimal disruption to the customer in the event of a fault.

I dont think you should even be fitting a mains board if you have to ask such a basic question such as how to lay out the circuits.

 

[ChrisElectrical88]

Also you havent answered the question on weather the main OCPD is 63A or below?

I think I know why the OP has taken the guts out of the board; perhaps he doesn’t want us all to see the cu installation ..
Please take a photo of the consumer unit

So you have put in an spd then

 

[DPG]

Are you DIY? No shame if you are, but an electrician wouldn't need to ask which circuits to put on which side of a CU.

 

[buzzlightyear]

So you have in an spud in then /QUOTE ]

Oops and now it’s just tripped the rcd, taking everything out apart from the shower, watch you don’t fall over them on that lovely wooden floor
