Okay, but the oven tells you: use at least 8mm^2 wire, and then it goes up in flames because hey sometime you actually need 10mm^2...

Quote from the internet in reference to 10mm2 wire gauge:

"This metric wire size is common in industrial settings for high-power devices and main circuits where thicker conductors are needed for safety and efficiency."

That would be quite some oven.
