Induction Hob & Oven Connection: Choosing Right Cable for 5x2.5, 16.1kW, 230V/400V, 3 Phase

Hello
I bought a set of induction hob plus an oven (without manual) used equipment
The plate is connected directly to the oven with cubes
On Monday, an electrician will come to connect my equipment, I will have to buy a cable to connect
Is 5x2.5 cable enough
3 phase home power supply
Connection power 16.1kW
he writes only so much on stickers
Plate: 230 V * 50-60Hz, 230V 6.40 kW
Oven: max9200 W, 230 / 400V 3N ~, 50Hz

What length of the wire.

From the switchgear to the set of 13 m.

For sure?

It should be enough, but it's better to give 5x4.

This is written on the sticker: max 9200 W.
So it is better to buy 5x4?
And if in the future I change the equipment, where a 5x2.5 mm cable would suffice, will this 5x4 be able to stay, will I have to forge and introduce a new one?

He will be able to stay. If there is to be a plate on the same wire and this oven is the minimum four.
You have too little power allocation for these receivers.

What are the consequences of a small power allocation to the oven and electrics?
As for the stove, it probably will not use its full power.
And an electrician?
Can they knock out fuses?

And this 9200 W is sometimes not the power of the whole set
I do not want to believe that the oven itself is so powerful.

It will be so.

Where did you get 16.1 kW from?

9.2 kW is certainly the power of the whole set. It is barely ~ 13.3 A on a three-phase power supply, hence a 5x2,5 mm ^ 2 cable and 16 A protection will be sufficient. Manufacturers give factory for such equipment most often even 1.5 mm ^ 2 ...
With an allocation of 16.1 kW also will not be a problem, the pre-meter protection at this power is probably 25 A or the standard.
It is worth mentioning that recently, for example in the UK, a circuit for electric cookers with a power output, as given by the author of the topic, would be designed and made for a power of even less than 4.5 kW, because this is how the use of power by such devices really looks like. Situations in which all fields are set to max. in the oven all heaters are heating, they do not have a place, and if it is, then it is a short-lived condition that will not lead to heating of cables or release of security.

And if I use a 5x4 mm cable for this set, because I have already bought it, it will not be a problem?
The pre-meter protection is exactly 25 A.
Here I give the plate and oven model, maybe someone will find the exact data.
Plate: Ariston model KC 62 D0 1X
Oven: Ariston HO 87 EF.1 IX

Like the west and such numbers ...

You can apply.
