Solving for Conductor Area in Three-wire Three-Phase Circuits
  or  
Vd is always voltage drop,
I is the current in the conductor, measured in amperes,
L is the one-way length of the circuit, measured in feet,
Cm is the cross-section area of the conductor, measured in circular mils,
K is the resistance of one circular mil foot of the conductor, measured in ohms.
1 RESISTANCE K
2 CIRCUIT LENGTH L
3 CONDUCTOR CURRENT I
