In addition to solving your systems for a given maximum conductor temperature or conductor current, it is now also possible to directly calculate a cable system for a given maximum outer temperature.

Due to environmental constraints, safety regulations, or simply in order to avoid the drying-out of the surrounding soil, it might be desirable to set the outer temperature of an object, i.e. the surface temperature of a cable or duct, to a specific level. This new feature is now available when defining your load, in addition to the previously available options to define the load of a system either by the conductor current or the maximum conductor temperature.
As for a load defined by the conductor current, you can still provide an optional maximum allowable conductor temperature if you define the load by the maximum outer temperature. Cableizer will then alert you if this value is exceeded.
We have validated that the calculation of a specific project results in the same ampacity and temperatures independent of how you define the load. For convergence reasons and in order to speed up the simulation, however, we would like to advice you to use the conductor current as load input whenever available. If you have multiple cable systems, you can continue to select different load inputs for every cable system according to your requirements.
