      the loads is not large enough to require high ampacity conductors and breakers. It is very important for the designer to specify the rated AC voltage on the equipment specification. 4. 4.1.2 Three-Phase AC Source. Substations with three-phase voltage equipment and high station power load requirements should consider a three-phase AC source. Large bulk substations with high MVA autotransformers ...

      2007-06-10 · Low voltage dc systems often require parallel conductors in order to provide adequate ampacity. Parallel conductors are not unknown in industrial or utility systems, but are less used. Two conductors in close proximity will have a total ampacity that is less than the sum of each conductor alone, because of mutual heating. The benefit of one more conductor diminishes quickly as the …
