Feeder will be sized for FLA per NEC. Feeder impedance and source impedance will be converted to ohmic quantities. Voltage at MCC and motor during start will be calculated from product of locked-rotor current and circuit impedance. To simplify calculation, total voltage drop to motor = algebraic sum of voltage drop in service plus voltage drop in feeder will be used, rather than vector sum (conservative).
