Formula For Cable Sizing [upd] -

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

Selecting the correct cable size is critical for electrical safety, efficiency, and reliability. An undersized cable overheats, causes voltage drops, and risks fire. An oversized cable is unnecessarily expensive and difficult to install. formula for cable sizing
