UL 14AWG/18AWG wire, how many copper wire, the overall diameter of how many, cross-sectional area? What is the load current?
A complement to the hdsr178 is that the outer diameter of the stranded conductor is a range of different pitches and different monofilament diameters that affect the outside diameter
Current carrying capacity, the current carrying capacity of a conductor is also a range. A single conductor, a plurality of conductors, and a radiating environment can influence current carrying capacity, and the current in the table seems very conservative
