The existing cooker circuit is 6mm² on a B40. The customer wants to replace the free-standing cooker with 2 built-in ovens and an induction hob. Will each cable from cooker outlet to device need to be the full 6mm², (e.g HO7RN-F) or can I get away with anything smaller and more convenient (e.g. what's supplied with each oven/hob, if anything)? The final purchasing choice hasn't been made yet, so I don't know whether any of the devices will be suitable for a 13A plug/FCU, which can obviously accept a smaller cable.
But that means that the three 2.5mm flexes are only protected by a B40, which to my simple mind sounds wrong. Which is why I'm hoping someone wiser than me will explain about overload, short circuit, diversity, the non-diabetic equation, and lovingly quote some 5XX.X.X at me, such that I feel comfortable with 2.5mm.
