MCB Replacement

[nathanynysddu]

A neighbour has asked me install a 9.5kW electric shower, theres 10mm T&E cable installed but its an old MEM Consumer Unit. I obviously need a 40A MCB but Im struggling to find a replacement for the original. The current MCB's are MEM M6's, does anyone know which make/model is a direct replacement for these. Ive checked on eBay and the 40A MEM MCB is £28!

Have you checked that the circuit is OK to be on a B40?

And is it on a 30mA RCD?

M6 is the breaking capacity, not the model!

I'm guessing its possibly an old memra 21 board? if you post a picture of it we can confirm
