I dont know why they have to lie about it. At $5/8ft board you’d think I paid for the full 1.5. Edit: I mixed up nominal with actual.

    You use the chart. How does mm of a wire, including insulation, tell you ampacity? As I said it is easy to imagine a thick wire that can carry almost no current. You can’t pull that crap with AWG system. It tells you the single most important fact, how much current a wire can carry. There is no incentive for wire manufacturers to cheat the system since a thicker insulation wire just means more cost for them.

    Which ties in nicely with the other charts. Tell me how much power you need a motor to deliver and what I have to deal with and I can tell you exactly what wires to use, it’s bending radius how thick it is etc. None of which I can do in the CE system.

      Ironically outer insulation does impact conductor ampacity, because the rated continuous vs peak loads depend on the heat resistance rating of the insulation.
