FAQ — Kabeltverrsnitt for 90 Ampere ved 45 Meter (400V — NEK 400)
Hvilket kabeltverrsnitt må jeg bruke for 90A over 45 meter (400V)?
Etter NEK 400 anbefales 25 mm² kobberkabel for 90A ved 45 meter (400V), som gir et spenningsfall på 6.0V (1.5%).
Hvor mange kW tåler 90A ved 400V?
Kursen leverer opptil 62.35 kW med 90A vern.
