Three-Phase AC Voltage Drop Analyst
Commercial power system analysis using square root of three ($\sqrt{3} \approx 1.732$) phase multiplier for 3-wire and 4-wire systems.
Three-Phase Circular Mil Equation:
CM = (1.732 × K × I × D) / V_d
Evaluates industrial voltage drop against NEC 210.19(A) branch limits (3%) and NEC 215.2(A) combined feeder limits (5%).
