Here the recomendations are:
1) Lighting and outlets are on seperate circuits.
Here too... but that's what it is - a recommendation.
The dedicated circuit for each load >1.5kW is merely a recommendation too _and_ only applies to new wiring. Single phase loads exceeding 3.6kW (16A) do have to have a separate permission by the PoCo in Austria though.
The typical range is 9 or 9.5 kW here. The cooktop has 2 burners on one phase each and the third phase is for the oven. That means the oven never draws more than 16A @ 230V. Occasionally such ranges are connected via 25A single phase circuits, but that's only done in very old apartments where 3ph is not available, but in such a location that would usually already exceed the main fuse of 20A. So not really a good idea. Not that I think connecting an appliance that is capable of drawing like 41A to a 25amp circuit with 4mm2 or even 2.5mm2 wire, only relying on the OC protection is a good idea anyway...
Separate cooktops and ovens are fairly common here too, usually the cooktop is 3ph, only using 2 phases and the oven single phase, even sometimes connected via Schuko.
Dryers and washers don't exceed 3600W here. Our washing machine runs on a 10A Diazed fuse, but only if there's nothing else on that circuit. The refrigerator already blows the fuse.
