  Manually,
  Single phase voltage drop:
  Vd= 2K x L x I / Cm
  
  Three phase Voltage drop:
  Vd=1.73K x L x I / Cm
  
  Where,
  Vd = voltage drop
  K = 12.9 for resistance of copper conductor
  L = Length of circuit in feet
  I = current or amps. of load
  Cm = Area of conductor in circular mills
