Wire Gauge, Resistance, Cross Section & Current Table
NOTES:
1. Construction: C – Concentric; U – Unilay; R – Ropelay
2. Change of 3 AWG Numbers Doubles Resistance and Halves Weight
3. Properties of Copper:
a) Tensile Strength: Hardened copper: 478 N/mm² (47.8kgf/mm²) Annealed Copper: 239 N/mm² (23.9kgf/mm²)
b) Average Resistivity: 1.7241 microhm-cm at 20°C
c) Maximum Temperature: 200°C for SPC – 280°C for NPC – 155°C for TPC
