board selection for 63a main fuse.

[markysparky]

Hi I need a bit of help with selecting a board for a cu change that I am doing for my dad. It has a 63a main cut out. 16mm tails. It is a old wylex rewireable board. Many of the circuits have been doubled up, So with a few new circuits I am adding I need at least 10 ways

I am looking at getting a wylex NHRS15SSLHI, 5 plus 5 dual rcd, and 5 on main switch high integrity board. Going to put new smokes on rcbo and leave some spare ways for the future.

Now I am not very good on diversity and need some help re the main sw I should cover the board with. The wylex comes with a 100a, but is it right I can only use a 63a ms. Will this be ok with all the circuits in this size board? What would you guys recommend?

just stick with the 100A main switch. as long as its rated higher, it doesnt matter

If you think you need 10 ways get 12!

the NHRS15SSLHI has 15 ways

cheers guys, will go with bigger board as only cost

AFAIK it can be more not less. It's not a fuse it's just rated to handle UP TO 100A.
