OK now I have a problem, the Hob I bought is rated at 30Amps and the Oven is rated at 20Amps. Turns out it is not possible to connect these to same 32 Amp circuit (obviously!). So is it possible to upgrade to the circuit just by changing the MCB to 50Amps (assuming the cable that's there is rated for 50Amps) And then connect the oven and hob to that circuit?
