A comment on North American versus European distribution systems (2011). Parent comment
The electrical bill is structure so that you pay for the peak power consumption (kVA's) and how it's structured to favor 1 phase connections.
1 phase kVA options: 1,15; 2,30; 3,45; 4,60; 5,75; 6,90; .... 3 phase kVA options: 6,90; 10,35; ....
The kVAs levels increase by 5 Amps on each phase so you get much more levels on 1 phase connections.
