Thermal considerations for outdoor bus conductor design ampacity tables

Ampacities have been calculated for copper and aluminum bus conductors under outdoor conditions. Temperature rises of 30 ° to 110 ° were considered, with and without sun. Rectangular, tubular, angle, double angle, integral web, and double channel bus conductors are included in the tabulations. Formulas and assumptions used in the development of these tables were presented in detail in a previous paper.
