is 2.5mm2 cable fine from cooker switch to CCU?
From the CCU there will be a new induction hob and cooker.
I agree that it would make little sense, and that it would not be acceptable/compliant if the circuit were protected by a 32A MCB, given that the peak current demand of the cooking appliances would almost certainly exceed the CCC of the cable.If you mean would it be acceptable to install 2.5mm T&E between the Cooker Control Unit and the outlet plate of the oven and hob. I would say not!
True. If the total load was, as you suggest, around 33A, that would, as you imply, after application of diversity, be a small enough load to be supplied by 2.5mm² cable protected by a 20A MCB ... but that would not really make much sense - particularly if most of the circuit is already wired in 6mm² or 4mm² cable.Induction hobs are rarely rated at less than 20A and you would expect even a low output oven to repair a 13A fuse. ... I know it could be argued, that the demand maybe not a constant.
That would be the conventional approach. Given ideal (Method C) cable installation, 4mm² cable (with a 32A MCB) would theoretically be adequate - and, as you say, would be more than adequate for any future requirements (up to 19kW of cooking appliances, if there were no additional socket supplied by the circuit).But in this scenario, I would be putting 6mm cable in, which would allow for a demand up to 15kW, for any future proofing.
