Would the cpc not have sufficient surface area though with a16mm t/e with it only being 6mm

What does the adiabatic say?

 

[ElectricEddie]

Theoretically but it will be deeper than 50 mm

What size OCPD are you planning on using for the 4 x distribution circuits?

Do do you mean on each of the submain boards ?

The over current protective device that is protecting each 16mm T&E.

63amp each I was planning to use

 

[davesparks]

63A what?

 

[ElectricEddie]

63amp each I was planning to use

That is of course providing that I keep the set up in the same way distribution wise and don't use swa but my 16mm the is below 50 mm all the way through the run

I think I need to think about this a bit more and do some more calculations that you for everyone's input I will update in a couple of days

* thank you

The thing is Eddie if you use an mcb for the distribution circuits then you have next to no chance of discrimination with the final circuits.

edit: An RCD doesn't provide over current protection.

He asked for the OCPD, not the additional protection!

 

[Leesparkykent]

Best thing I think you can do is sit down and revaluate the whole design.

Yer I am going to cheers guys the issue regarding distribution has been the bit I have been stuck I want to get it right hence seeking advice on here I will get someone with more experience to come in and have a look but looks like I'm going to run it in swa i will properly calculate the csa's and get back to this forum afterwards, I appreciate this should have been done beforehand
