Select a cable where the .
[ A = \fracI_sc \times \sqrttk ] Where ( A ) = min cross-section (mm²), ( I_sc ) = short-circuit current (A), ( t ) = disconnection time (s), ( k ) = material constant (e.g., 143 for copper PVC).
[ V_d = \frac2 \times L \times I \times R_cable1000 ] Where ( R_cable ) = resistance in Ω/km from cable data.
[ I = \fracPV ]
( 0.03 \times 230 = 6.9 \text V )
19.53 V > 6.9 V → → increase cable size.
