FAQ — Kabeltverrsnitt for 800 Ampere ved 70 Meter (400V — NEK 400)
Hvilket kabeltverrsnitt må jeg bruke for 800A over 70 meter (400V)?
Etter NEK 400 anbefales 2× 400 mm² kobberkabel for 800A ved 70 meter (400V), som gir et spenningsfall på 2.6V (0.65%).
Hvor mange kW tåler 800A ved 400V?
Kursen leverer opptil 554.26 kW med 800A vern.
