[ I = \fracPV \times \textPower Factor ] Select a cable where the

Selecting the correct cable size is critical for electrical safety, efficiency, and longevity. An undersized cable can overheat, cause a voltage drop, or start a fire. An oversized cable is unnecessarily expensive and difficult to terminate. cause a voltage drop

[ V_d = \frac\sqrt3 \times L \times I \times (R\cos\phi + X\sin\phi)1000 ]

[ V_d = \frac2 \times L \times I \times R_cable1000 ] Where ( R_cable ) = resistance in Ω/km from cable data.
