FIECAG-A User Oriented Utility Program for Ampacity Calculation of Power Cables on a Desktop Computer

Power cable ampacities for a wide range of conditions can be calculated with a minimum of data Input, using a library-supported desk-top computer program aimed at regular as well as casual users. The program, based on the Neher-McGrath/IEC method, Is further enhanced by Its ability to retain reference files of previous calculations and compare alternative solutions. The Initial library of 47 distribution cables, included in the data base, eliminates the need for time consuming input procedures. The computerized algorithms of the program contain several enhancements to the IEC method which allow it to deal effectively with the special nature of modern distribution cables and permit the study of a wider range of cable systems. An application of the program for ampacity calculatlons of six cables in a duct bank is shown for the purpose of Illustration.
