FAQ — Kabeltverrsnitt for 300 Ampere ved 25 Meter (230V — NEK 400)
Hvilket kabeltverrsnitt må jeg bruke for 300A over 25 meter (230V)?
Etter NEK 400 anbefales 150 mm² kobberkabel for 300A ved 25 meter (230V), som gir et spenningsfall på 2.14V (0.93%).
Hvor mange kW tåler 300A ved 230V?
Kursen leverer opptil 69.0 kW med 300A vern.
