In low density areas in the USA there isn't always three-phase on the pole. The substation that our feeder is on is about eight miles away and about halfway here one phase turns down a side road to feed some other farms. To get three-phase I'd have to pay Excel to string the missing wire. The line is also 7 KV so I'd have to pay for two more transformers. At our place in Minneapolis, on the other hand, there was 240 three-phase on the pole fed from a set of transformers at the end of the block. I could have had three-phase in the house just by paying for the wire. Of course, any rf I had put on the house wiring would have gone to every house on the block... -- John Hasler jhas...@newsguy.com Elmwood, WI USA
