Yes, but the 10mm, might be an Imperial size.
Is this 6mm or 10mm cable?

How might a 10mm item be imperial?
Why not 6mm for ovens? Thats the best stuff....easier to work with than 10mm anyway.
10mm is the supply into a small ‘sub’ CU that controls the kitchen/extension When the kitchen gets done I’m interested in having two double ovens and maybe an induction hob.
It’s currently gas so there’ll need to be a cable out and I read anything over 15kW should be 10mm. Probably only Christmas Day when they all might be on full blast.
How, might it not be a possibility? From memory - It could be 7/052 T&E
In which case it wouldn't be 10mm² size and not if it's dated 1999.

Now please use a pair of pliers to squash the strands down into a line (touching) like ooooooo when viewed end-on, and put a ruler next to it then post a pic; let’s put some science at it
I didn't hear a date of manufacture mentioned..
You never heard of text to speech?
Yep, but I don't use it for forum posts - do you?
For domestic cooking equipment the diversitiy guidelines say
first 10 amps + 30% of the remainder + 5A if there is a socket.
We can work that backwards to work out the maximum cooking load for a given circuit.
With socket: ((i-10-5)/0.3 + 10) * 230
Without socket: ((i-10)/0.3 + 10) * 230
32A -> 15.3kW with socket, 19.1kW without socket
40A -> 21.4kW with socket, 25.3kW without socket
45A -> 25.3kW with socket, 29.1kW without socket
50A -> 29.1kW with socket, 32.6kW without socket.
Cable ratings depend on installation methods
For 32A you will need a minimum of 4mm under method C, a minimum of 6mm under method 100,102, or A and a minimum of 10mm under methods 101 or 103.
For 40A or 45A you will need a minimum of 6mm under method C, a minimum of 10mm under method 100,102, or A and a minimum of 16mm under methods 101 or 103.
For 50A you will need a minimum of 10mm under method C, a minimum of 10mm under method 100,102, or A and no size of T&E will meet the requirements under methods 101 or 103.
Unfortunately, not all brands offer 45A breakers.

Maybe "unfortunately", but are there actually (m)any domestic cookers >25A (or even >21A)?

That's my experience too. 4 milli has a 1.5 CPC, 6 has a 2.5 CPC, both solid, 10 has a 4 milli CPC and 16 has a 6 milli CPC, both stranded.
