I am having a grain bin erected and need to power it.
I have a 100 amp service at the pole. The grain bin in 250' away from the pole.
I will have a second grain in built next year right next to it. So, I'd like to size the wire to run it once or run a pair of feeder wires so I don't have to come back next year.
Each grain bin consists of the following: 1) Fan with a 10HP, 230v single phase 2) Unload auger with two identical motors - 7.5hp single phase 230v
Grand total, I'll be powering two 10hp and four 7.5hp.
What wire do I need to run from the pole to the bin(s)?
