I have a customer that wants the POCO to supply a 400A 120/240 service, then he wants to install his own poles to run 4160v up his 3000' drive way.
The customer will own the transformers and the overhead line.
Any body know of any code issues with this?
I don't know of any. But I have only seen one. It was 2400V, about a mile.
The POCO supplied one pole about 200' up the access road and a normal 240V, 200A, service drop to his pole mounted meter/disconnect. A 2 pole, 60A CB fed a 15kva 2400/240/120 transformer. 5000' of pretty small al, 2 single conductors, direct burial, to his house, to another 2400/240/120 15kva transformer. One side of the 2400V grounded. He had a primary disconnect at the second transformer. The transformer secondary went direct to a 100A panel, 60A main.
He said the worst was getting all the land owners to allow him an easment. Second worst was the two weeks it took him to dig the ditch.
The only issues I see are naysayers and fear
Of course, this one is 100kva, not 15kva and that is a bit heavier equipment.
