Cable Sizing Calculation — Electrical

[ I_0 \geq I_z ] [ \Delta U = \sqrt3 \cdot I_b \cdot L \cdot (R\cos\phi + X\sin\phi) \quad \text(3-phase) ]

[ I_b \leq I_n \leq I_z ] [ I_z = \fracI_nC_a \cdot C_g \cdot C_i \cdot C_c ] electrical cable sizing calculation

If voltage drop exceeds limit, increase cable size. Minimum cross-section for short-circuit: [ I_0 \geq I_z ] [ \Delta U

[ A_min = \fracI_sc \cdot \sqrttk ]
