I guess in Germany we had a unique situation, as after WW2 a lot of infrastructure was destroyed and when it came to new installations, in urban and industrial areas 3 phase was chosen. Guess in the Fifties most of the "farmers`s lines" were taken out and 3 phase came in. Even cars and motorbikes have 3 phase alternators now. If material is of concern and energy transfer not too demanding, then single phase can do it. Look at the US, in a lot of areas, not only the remote ones, you find "farmer`s lines" even in the middle of a city. Low voltages have to be paid for by conductor size and heating of connections. The later posing an everlasting threat to home appliance security. 73 de wolf
