Voltage Drop Calculation

As most motors are designed to operate with a 5% voltage drop, divide volts lost by line voltage x 100 to determine if a larger conductor or additional feed points are required.
  • 3 phase AC Volts lost = 1.73 x Z x Length in ft. from feed x Amp. load
  • 1 phase AC Volts lost = 2 x Z x Length in ft. from feed x Amp. load
  • DC Volts lost = 2 x R x Length in ft. from feed x Amp. load
