1/0 195 0.00040
2/0 225 0.00032
3/0 260 0.00025
4/0 300 0.00020
Notes:
1. Ampacity is based on 30 °C ambient temperature with conductor rated at 60 °C. For ambient temperature other
than 30 °C, multiply the above ampacities by the following constants:
Temperature (°C) Constant
21 - 25 1.08
26 - 30 1.00
31 - 35 0.91
36 - 40 0.82
41 - 45 0.71
46- 50 0.58
51 - 55 0.41
2. Resistance is nominal at 75 °C wire temperature.
