Cable cross-section calculator
For the purposes of the calculation, a constant voltage drop of 1.5% for 230V and 2% for 400V was assumed for three phases and the cable operating temperature ranged from -25°C to +60°C.
Popular wire cross-sections are: 1 mm², 1.5 mm², 2.5 mm², 4 mm², 6 mm², 10 mm², 16 mm², 25 mm².
