FAQ — Kabeltverrsnitt for 200 Ampere ved 40 Meter (230V — NEK 400)
Hvilket kabeltverrsnitt må jeg bruke for 200A over 40 meter (230V)?
Etter NEK 400 anbefales 95 mm² kobberkabel for 200A ved 40 meter (230V), som gir et spenningsfall på 3.6V (1.57%).
Hvor mange kW tåler 200A ved 230V?
Kursen leverer opptil 46.0 kW med 200A vern.
