Replacing kitchen ring with 2 radials

As I've said, I suspect that he may just have overlooked' the possibility of fitting a 20A MCB!

Do we know that it's not an obsolete CU for which he can't find a 20A?

if it were all installed in one (or more) of those ways, would give 2.5mm² cable a current-carrying-capacity of 27A, adequate for a 25A MCB, let alone a 20A one.

25A is an unusual value.

No, we don't - that's why I wrote:

Of course, it remains possible that he knows something that we don't which means that you are 'stuck' with 16A MCBs if you split the ring.

It is indeed. That's why I wrote:

... (indeed, depending upon the routing of the cable, if one is available for your CU, even 25A MCBs might be acceptable)....

Are you currently 'marking' today's posts to the forum?

Pot kettle,

Maybe, but I think you'll find that there is a very big difference in scale, and also a big difference between what is usually 'tongue-in-cheek' and that which is intended as deadly serious!

Kind Regards, John
