I have a customer that needs a well wired up. the well head is 410 feet from the house and a 30 amp circuit. using the normal volt drop formula to stay within 3-5% for the motor i would use #2AL use and run a direct burial ground with it.
after talking to the well company they said i can use normal 10-3 uf to feed the pump motor in fact the spec sheet they faxed me says i could go 1020 feet. why is this? is the volt drop not a factor because the motor is in water vitually liguid cooled?
i was curious to other ideas or if anyone else has run across this scenerio too.
thanks,
H20
