Size Calculator: Cable

Increase to 16 mm² Cu PVC: rating ~85 A, voltage drop ~2.9 mV/A/m. ( V_d = \frac2 \times 60 \times 30 \times 2.91000 = 10.44 , V ) → 4.5% → still slightly above 3%.

Increase to 25 mm²: voltage drop ~1.9 mV/A/m ( V_d = \frac2 \times 60 \times 30 \times 1.91000 = 6.84 , V ) → 2.97% → passes. cable size calculator

A cable size calculator is a tool (manual formula, online app, or software) that determines the minimum cross-sectional area (e.g., mm², AWG) of an electrical cable required to safely carry a specified current under given installation conditions.
