Most often they have a larger pump that feeds water several of these pivots. Then each pivot has a long run of underground that comes from the pumps electrical panel. I ran across one that was over 1,500 ft away. As far as how many amps they draw depends on how long the pivot it. Each set of wheels has an electric motor. A farmer once told me how many horsepower each motor was but I forgot. I think they are like 1/3hp or something. They can’t really draw too much because that 1,500 ft run was a #4 copper stranded. So max is 85 amps per leg of the 3 phase.

Ah, gotcha. It's a bit more moist out this way, you have to head west to find the center pivots, never knew much about them.

They have all their pivots setup on their phones around here. They can see when a pivot will complete its rotation, how much water they are using, add fertilizer, get alerted if a pivot shuts off, start and stop them… you name it. We got some high tech farmers around here. Lol

Lol, that's so wild.
