I need to wire in a Bosch Induction hob and single oven
The hob has a max power rating of 7200W
The oven has a max power rating of 2200W
I have an older Wylex Type B Consumer Unit with 2 spare 30A connections at present (1 was the old cooker wiring which was disconnected way back when a gas hob/oven was fitted, 1 was the immersion heater (I think) which has just been removed as I've had a combi boiler installed).
My plan was to run 10mm2 cable from one of these spare fuses to power both the hob and the oven. This should be fairly easy run apart from getting it down a wall as it's all plaster on to blockwork. But I should be able to manage that.
This 10mm would then run to 2 cooker switches on the wall, with 1 running 10mm to the hob and the other running 2.5mm for the oven. Both would go to cooker connection points behind the oven.
At the CU I would replace a 30A fuse with one of the modern MCB adapter fittings.
The max I can find (B&Q, Homebase) is 40A, which seems a bit marginal to me for both appliances from what I've read on the Internet, this forum included.
Working off 240V the oven will take 9.2A and the hob 30A, so 39.2A max.
<Questions>
1) Would I need to try and track down a 45A MCB, or would a better plan be to run the hob over 10mm from a 32A MCB and use the other blank to run a 16A over 6mm to the oven?
2) There is a ring main next to the current oven point, could I not simply run 2.5mm from this to a switch and then to the oven?
3) Can someone have a look through my plan and see if there's any thing I may have wrong.
