If voltage drop exceeds limit, increase cable size. Minimum cross-section for short-circuit:
Where: (P) = load power (W) (U_L) = line-to-line voltage (V) (\cos\phi) = power factor Choose a standard rating (e.g., 16A, 20A, 32A, 40A) such that: electrical cable sizing calculation
[ A_min = \fracI_sc \cdot \sqrttk ]
