When designing electrical installations, part of the process involves selecting rating factors that are needed to adjust a conductors tabulated current carrying capacity to accommodate the differing factors that the unique method of installation has introduced.
If we just select all of the appropriate rating factors within a cables run however, we may waste our design and oversixe cable selections (probably complying with future 18th edition Part 8 in the process).
This video just illustrates how to determine which rating factors we should use when carrying out our designs.
