Engineering Data
- Cross Sectional Area
Cross Sectional area = π/4xd² mm² Where d = conductor diameter in mm - Weight of Conductor
Copper conductor : 6.98218 x (d)² Where d = conductor dia Based on Density of copper = 8.890 g/cc - Conductor resistance Copper Conductor
Nominal resistivity annealed conductor, as in enamelled wire, according to IEC 60317-0-1 specification = 1/58.5=0.017094 ohm.mm²/m
For AWG sizes, Resistivity as specified in NEMA MW 1000-2003 = max. 0.017241 (=1/58) ohm.mm²/m, corresponding to conductivity 100%(IACS) is taken as base.
