Hi they are based on tried and tested unit system method the IET have established over many years. The numbers do not have a unit they are just factors taken form table from the IET guides. Hope that helped, please share with like minded people or even like and subscribe.

Why are the elctrical affects of grouping not factored ??

Hi, Because the number of circuits (not conductors) is not known or the loading of each circuit - this will have an impact on grouping and would be considered by the designer, which may change the cable size and therefore containment size. Hope that helps. Please Like, Share & Subscribe.
