You rate the MCB not on the cooker load, but on the grade of cable going
to it. The purpose of the MCB is to prevent cables catching fire, so if
its decent grade cooker cable 45A or 50A MCB is in order.


Yes I realise that, just didnt want it so that we got a cooker that kept
tripping the mcb. Main problem is replacing the cable is not an option (too
many rooms/walls).
