What problems do you think you will have?

 

[sahelectrical]

just id like to see how to dress them and dress the rcbo cables etc

Only caution i would suggest is plan the supply cable entry if its large, sometimes entering from lower left or right side allows for large cores to be swept to main switch.... as appose to bottom center which can leave you struggling to terminate cores even with extension box, but it all board (brand) dependant and also size of cable.

the armour is terminated in bottom but i have large entry at top for 4mm and 2.5mm singles just wondering mabye if anyone had pics of dbs theve done

It all depends of what brand of board you have, it will be plain obvious to you when you get going, will the RCBO's you fitting have the little earth lead? they know how to make a mess of things.

I dont like putting RCBO's in some Hager boards as the cables to the RCBO's block the terminal screws on the Earth and Neutral bars.

Bigger question is, what method will you label the board?

 

[sahelectrical]

[Mark_Burgess]

No pics, I never remember to take any of instals just PIR failures!
