  • How do you calculate the maximum current rating per conductor?

  • To calculate the maximum current rating per conductor, multiply the chart value by the appropriate conductor factor. The chart assumes the cable is surrounded by still air at an ambient temperature of 25C. Current values are in RMS amperes and are valid for copper conductors only.
