For that matter, US ranges generally require a minimum 40A circuit.
We do have a derating factor, of course. Any range rated 12kW or less is assigned a demand of 8kW.
Taking a trip to the local big box store, I see most ranges are between 10.5-12kW. That's for 4 surface elements and electric oven. "Dual-fuel" ranges are also available--gas cooktop with electric convection oven (though nothing like the options they have in France, 3 electric surface elements and 1 gas burner). Cases such as these may warrant a 30A circuit.
The typical electric range may have either a 40A or 50A circuit. In either case, a 50A receptacle is used. (NEMA 10-50 before 1996, NEMA 14-50 after.)
