Re: OT: Wiring Questions

If Jason doesn't reply to this (he's the first one that comes iot mind for wiring) by Monday, I'll ask one of our engineers at work to look it up. They've all got these neat little wire size calculators that they use on a regular basis. Example, the pump station has a 75 HP 480V 3ph motor, and the circle requires so much power, the distance is this far; what gauge of wire do I need to run from the meter base to the feeder?

FWIW, we use 14ga THHN to wire preasure switches in for irrigation use.
