Conductor dc resistance calculator (IEC 60228)


Stranded conductors for single core and multicore cable (IEC 60228 Class 2 Table 2) 50sqmm and above. This calculator uses the more exact formulae used in Clause 6 for copper and aluminium conductors. Metal-coated wires are not included in this calculator.

Conductor metal =
Conductor size = sq.mm
Conductor temperature = Celsius
Conductor length = metres
Max allowed dc resistance by IEC 60228 at 20C = mOhms
Max allowed dc resistance by IEC 60228 at Celsius = mOhms
