I'm looking at a new electric cooker with an induction hob. The instructions state that it draws a maximum of 10.8KW and that the 'fuse rating' is 46.5A. So what size breaker will it need in the CU (currently 32A, so not big enough) and will it need an updated cable? Several people have asked about this is in the Q&A on the manufacturer's website but the reply is that 'your electrician will advise you about installation requirements'. I'd just like a rough idea before going any further - I have no intention of fitting this myself.
Requirements for new cooker?

mmm.
Seems like an oddly-specific rating, googling it doesn't seem to turn anything up either.
10.8KW at 230V is about 47A.
However, we are allowed to apply what is known as "diversity", basically it is considered unreasonable to assume that everything will be operating at it's maximum power all at once, if we designed installations like that then we would quickly end up with insane overkill.
For domestic cooker circuits the guidelines are first 10A, plus 30% of the remainder, plus 5A if there is a socket on the cooker circuit. So that gives us a value after diversity, 21.1A without a socket or 26.1A with one. So putting your cooker on a 32A circuit is within the guidelines.
The existing standard cooker circuit will be satisfactory for your new cooker - and indeed any cooker up to 20kW.
Showers are different.

Do not change the circuit breaker
And the existing 32A circuit is more than adequate for the oven and hob

Thanks for all the useful replies. So would the fitters from the delivery company be OK to hook everything up? They charge about £100, which is similar to having my own electrician I suppose. I'm sure that the company that did my EICR and new CU would do it - the problem with these deliveries is that you don't know until the day before roughly what time they'll be coming and even then they're often delayed. I don't want the electricians wasting their time, or do you guys see that as part and parcel of the job? (The company are removing the old cooker and 'recycling' it).
Probably not. They will not (usually) do anything that is outside their stated procedure.
Don’t think so. Anything other than a cable undo and reconnect they won’t touch it
