Installing induction hob+electric oven...separate circuits or same?

[les24preludes]

New kitchen - induction hob at 7.4kW (32amp) and oven at 3.6kW (16amp) max ratings. Existing outlets are:
1. 45amp fused cooker circuit
2. fused socket off ring main (32A fuse)

Can both oven and hob be connected off the one 45amp cooker circuit? That's right up to the maximum.

Or can the oven be connected to the ring main?

Or does the oven require its own circuit - that would be an extra installation and need rewiring to the fuse box.

Yes agree, but with most ovens for example, you cannot have the main oven selected with the side, top or bottom element. And vise versa. So a suitable cable would be supplied for the maximum possible culmination of load. Same cannot be said of electric hobs, but I haven't seen any hobs with a manufacturers cable?

Yeah it was a hob I was on about.

I have a NEFF hob, that came fitted with a cable. It was a 5-core cable that can be configured to meet single/multi phase supplies..

Others i have fitted did need a cable to be supplied and fitted.

That's hob not oven.
I came across some from aeg and electrolux that ask for min 16 and max 20amp fuse.
It may be to stop people wire them in to the kitchen rings through 20amp isolator.

I went once to check one. Turn out it was 3.6kw oven and was connected with 13 amp plug to the socket. It last almost a 1 year before fuse went and burn socket slightly. Customer got new oven and this one looks really nice in my kitchen now...
