Welcome to Ducab Select, the ultimate solution for cable selection.  This cable sizing and selection programme is specially designed to calculate cable size for a variety of electrical loads and installation conditions. All parameters entered by the user should reflect the actual installation conditions. All results have adequate current carrying capacities given the entered conditions. However for compliance with other electrical system requirements e.g. selection of protective devices, the user should make his own provisions. The results are intended only as a guide to cable size, and Ducab cannot accept any responsibility or liability whatsoever from the use of this programme.
