Voltage Drop

[!info] Ohm's Law

V = I \times R \quad R = \frac{ V }{ I }

Vd = \frac{ I \times R \times L \times M }{ P }

L = \frac{ Vd }{ I \times M } \times \frac{ P }{ R }

where

• Vd = Maximum Voltage Drop in volts
• I = Current in Amps
• R = Resistance in ohms per foot
• L = Length of wire one way in feet
• M = Multiplier
  • 2 for 1-phase
  • \sqrt{3} for 3-phase
• P = Number of parallel runs
