Any confirmation?

Unless I'm missing something new in later editions of the regs or other guidance that I hold:
14950/230 = 65A
10+(55*0.3) = 10+(16.5) = 26.5
Do you mean other than first hand experience?
Use 240 as the manufacturer will have done - even less at 230V.
I mean the confirmation I asked for in the post to which you responded.

Then you were taught incorrectly.
You are still using 230V on Wattages that will have been given for 240V.

What have I missed?
Oh I know all that and having been criticised within this forum for applying such calculations.
I have on a number of occasions worked with equipment with ratings plates calculated at 230V or even 220V.
Therefore I now revert to our standard voltage calculations and avoid making assumptions until I know the facts.
Without knowing the models being proposed and therefore the actual power ratings I have nothing else to go on.
Oh FFS.
Then don't bother replying, then.
FFS we can all shout and holler.
This whole exchange was based on a fairly throwaway comment, albeit with a fairly sensible intention and as I see it the criticism of that comment was this:
Having been in the situation of a cooking appliance tripping the MCB on overcurrent during heavy use (as it happens not at Christmas) I don't think the original comment is as silly as many would seem to think.
The only 'official' confirmation of any gut feeling is circuit design within the regs for any other appliance. IE any other appliance rated at 14.95KW would not have diversity applied to it. However we all know there is a special case for cooking appliances for which
although I'd put the figure way higher at above 99% with a number of 9's after the decimal point.
Now as it happens; many many years ago I was in conversation with one of the members who helped establish the cooker diversity rules, he explained the figures used were solely to get a particular cooker (of which most at the time were very similar) compliant on 30A fuse. It had to be amended as most cooker switches included a 15A socket (Now 13A of course).
From what im rrading this seems to be a bone of contention amoungst electricians even though the regs seem to support it.
For i just want to be sure that if i turn on teo ovens at 200c and have two maybe 3 things on the go on the hob at the same time it wont trip. This for me would be worst case "Xmas Day" scenario.
As it stands oir electrician is saying no possible which means we would have to move where we want the ovens on the island under the hob to another location in the kitchen which quite frankly looks naff.

Why don't you tell us what models of appliance you have in mind?
It would also be useful to see a pic of your consumer unit
And very very useful to know the size of your existing cable.
I previously had a range circuit with a 40A MCB.
Luckily there is no need to reposition your ovens, because electrical cables can run from one place to another.
