That’s 14kW a whole range doesn’t pull that much on full blast. There’s plenty of ovens in the 3600W range meaning they run off bog-standard 240V@16A lines here but chances are you’re in luck and your kitchen has 20A three-phase… also 14kW (in star configuration), intended precisely for the range, roughly divided into two for the top and one for the oven. Not much more copper so it became standard quite a while back, while 30A would be massive. Also more neutral wires.
