The uniform temperature cable ampacity calculation approach is based on the equal temperature criterion for cable current capacity calculation. The cable ampacity assessment determines the maximum allowable load currents when all the cables in the system have their temperature within a small range of the temperature limit. Since all the conductors in a cable branch are assumed to equally share the load current, in the case where these conductors are not located in the same conduit/location, they may not have the same temperature. When this situation occurs, the temperature of the hottest conductor in this cable branch will be used to represent this cable branch. The uniform cable temperature calculation method is part of the overall ETAP Cable Thermal Analysis software
