20A sounds low until you realize that it is likely 3x 20A at 230V (400V three-phase) so it is almost 14kW. I believe that most houses where I lived in The Netherlands had a single 25A or 35A main fuse (not accessible to the home owner, only to the utility) as most homes were only fed from a single phase and alternating phases were connected in the subsequent homes in the street. The home itself had typically between 3 to 6 circuits that were fused with 16A. Only if you requested an upgrade, for example for electric cooking, would you get a new meter and 3 main fuses installed and then you could install a 3-phase outlet providing 400V instead of 230 single phase. I believe that it was allowed to use 3 separate fuses or breakers to feed the 3-phase outlet since it was never used without Neutral.

You can't charge 2 EVs at once, if they have 3.3kW chargers, is this not so? Even charging one 3.3kW EV would mean little power left for other uses in the house. Here in the US, my older home has a 100 amp main circuit breaker (that is, a pair of breakers mechanically fastened together, one breaker for each 120v "hot leg" of the line). Most newer houses in the US have a 200 amp main breaker at 240 volts, so they can (in theory) supply up to 48kW. Some very large houses have 400 amp service (96kW).
