- Understanding the 75°C vs 90°C column in Ampacity Table. . .
The columns indicate how much amperage is required to raise the temperature of that size conductor to that column's temperature under standardized conditions So a 2 0 XHHW will reach 75°C at 135A and 90°C at 150A The wire insulation is good for 90°C, so for sizing the wire, we can use the
