Typical kitchen here used to have about 2 outlets, at least one of them usually upgraded to Schuko by pulling a ground wire to the water line closest by. For example, when we moved into our current apartment we found: 1 Schuko socket next to the door (single gang box with a horrendously expensive switch/receptacle device, or to be honest no box at all, just a hole in the wall, outlet was partially wired with 0.75mm2 zip cord wrapped in cloth tape, no ground at all) and a dedicated Schuko socket for the fridge, located inside a built-in closet (door had been removed). The wiring of said socket had a certain finesse, the installer managed to hook up the wires ensuring _no_ wire had the right color. Yellow/green phase, black neutral and blue ground. No idea how dumb you have to be to do that. Hardly any old apartment here in Vienna has more than 25A single phase, often only 20A. The services don't get upgraded, because more than 25A would require larger Diazed III fuses that usually don't fit the old enclosures. Besides, if a house with 8 apartments only has 60A per phase one apartment can hardly get more than the old 20A. If there's an electric range there's the possibility of a 25A 3ph service, but that's the absolute maximum for old houses. We've got our 200m2 apartment split over 2 services, 1x 20A 1ph and 1x 25A 1ph. About half the apartments here have 3ph for better load distribution (as far as I know there are 2 electric ranges and 2 apartments w/ 3ph and no electric range).
