I have two new submersible pump installs along with a control panel. The power system is a 480/277 wye. The voltage is balanced within 1% or so across the three legs and from leg to ground. When retrieving a amp draw on the pumps, the middle leg amps about 10 amps higher on both pumps than on the other two legs. I am getting this amp info from the bottom of the motor starter. Anybody give me some direction on why this is?
