FAQ — Kabeltverrsnitt for 250 Ampere ved 400 Meter (230V — NEK 400)
Hvilket kabeltverrsnitt må jeg bruke for 250A over 400 meter (230V)?
Etter NEK 400 anbefales 2× 400 mm² kobberkabel for 250A ved 400 meter (230V), som gir et spenningsfall på 5.35V (2.33%).
Hvor mange kW tåler 250A ved 230V?
Kursen leverer opptil 57.5 kW med 250A vern.
