Stamcon,
The closest 3 phase that I know of is about 8 miles from my mill. There are probably around 40 houses between my mill and there including my own house which has a separate 200 amp service from the mill. I am not sure of the whereabouts of the transformer that drops the voltage from 460 to 230. Wouldn't that transformer be were the 3 phase ends? I am at the end of the power line about 1 mile from my closest neighbor. behind my place is 3,080 acres of private land on the other side of that is around 25,000 acres of national forest.
