And one other thing that might be mentioned Franz, is that there are no pesky starting circuits or capacitors, or switches, or,...or...or... SO MUCH LESS machinery with the squirrel cage induction motors!!! Three-phase IS nice to have, no doubt about it. The modern conversion to 208V three phase for light industrial uses is an attempt to be able to use all three legs for single phase loads such as in hospitals, office buildings, and schools. Some of the early stuff had a "stinger" leg which was high voltage and useless for the 120V circuits. I have got "burnt" a few times buying used equipment that was 240 volts ONLY and just would not run on 208. In large buildings, even the lighting is three-phase with 480V on the power leg. Good way to get killed if you don't know about it.
