My line is prepared for 40 kW 3 phases, since the former owner also
used electric heating (this kind of night loading heating), but since
I switched for gas, I can use anything for my computers :)))

In facht it is 400V/230V since more than 10 to 15 years, but everybody
is still talking about 380V/220V ... And yes, 3 phases are the only kind
of connections the power companies offer - so the outlets will be split
up among the phases to get an even load (3 phases outlets are not very
common :).
