@Macmhuirich is yours dual fuel or all electric ??
The spec for dual fuel says - as below - 7.4kW. You don’t need 10mm for that.

Or in other words 6mm²

If the beast is all electric then the delivery person might be right. There are several variants of this oven.
We need to know which one!

It was the 110 Induction model in the first link.

[pete01]

So 6mm² then, we got there eventually

 

[EFLImpudence]

Or 4mm².

But the spec at the end of that document says 16.24kW!

Or 4mm².

Still happy with 4mm?

Yes, not that they will all be on together.

As Rodders worked out in post 25:

Which by my sums would be nearly 71 Amps - but allowing for diversity is 10A + 0.3 x 61 A = 10+18.3 = 28.3 A... so within a B32 MCB rating. Unless the cooker is fed from a switch with a13A socket; in which case the + 5A extra tips it over.

So, don't have a socket.

You either believe in diversity or you don't.

Still happy with 4mm?

Yes, I don't use BS3036 30A fuses any more.

 

[pete01]

I'd use 6mm out of pure habit

 

[EFLImpudence]

People do.

You either believe in diversity or you don't.

Having suffered due to and repaired the damage caused by diversity on several occasions... no I don't agree to the extent that others religiously adhere to the regs.
MI's are usually a far better guide.

 

[pete01]

I would do but I dont need a new cooker

 

[EFLImpudence]

You do seem to have a lot of bad luck.

no I don't agree to the extent that others religiously adhere to the regs.

Ok?

MI's are usually a far better guide.

Rubbish.

 

[pete01]

Having suffered due to and repaired the damage caused by diversity on several occasions...

What happened?

What happened?

tripping MCB's and melted cables
