Induction hob and electric oven running from same 32 questions... Again

[123]

@123 the cooker circuit is RCD protected. See the pictures!

It's not limited to the cooker circuit though. In general a kitchen can entail movement of Water Heater, Central Heating, Lighting. If it was all in that place before fine no problem, but once you start to move and relocate it then it's RCD time.

Yes, 32A will be more than adequate.
He/you will need a dual appliance connector if both appliances wire in.

If the oven is on a plug, he will need to add a 13A socket. This can be wired from the cooker connection point/

I have an existing double electric oven with a dedicated supply, think its 32Amp. The oven has a maximum rating of 5.8 kW.

I want to fit an induction hob (7.4kW) nearby can I use the same cable or will I need a dedicated supply for the hob ?

Excuse my ignorance but I have been using this calculation (rightly or wrongly) Total demand (theoretically) 13.2 kW which equates to 55 Amps.

Take 10 Amps off and multiply by 30% = 45Amps @ 30% = 13.5 Amp plus 10 Amp and 5 Amp safety margin giving a total Amperage of 28.5 Amps, would current 32 Amp supply cable therefore be adequate??

I apply diversity to the two appliances separately. Which computes to 31A ish, not adding the 5A for the socket.

Ah ok so a 32 Amp supply would still be ok ?

It would be. If its a new kitchen or refurb, I might be tempted to run a new radial for one or the other, just to cover its right on the limit and provide separate supply if one of your devices go wibble, and provides separate isolation. You can then add a socket ccc.
