wylex mcb

[The apprentice]

K7665sMET this is the product code if you google it will show you the consumer unit not sure what type of mcb would go in this wylex board

K7665 is an MK part number, so a wylex mcb will not be suitable.

Apparently that CU is one of the Sentry range so I guess any of the matching MCBs would do:

MCB Single Pole Type B

That all depends on why you are there and what you are doing?

Firstly how have you confirmed that two rings are connected to one MCB?

As @davesparks says, you have to confirm it really is two separate rings. Before the discussions on the wisdom (or otherwise) of that configuration is resumed it is worth noting that question has been discussed in a lot of detail recently:

More importantly if you do put them on separate MCB is to make sure they are separate - a 'figure of eight' on two parallel MCB is very dangerous as you have 2.5mm cable on what is essentially a 64A circuit!

There is also this thing called a test meter...

Really, check the rings are complete, loop resistances are OK (L-L matching N-N, E-E in ratio), and properly labelled. Finally once all fitted, and both MCB open, double check the lives are still isolated.
