I might be missing something really simple, but I never understood this rule. If the device in question has 14 AWG wire standard, why do I have to feed it with 12 AWG? Are we trying to say that the manufacturer is not using the proper wire? A CIM on a 40 AMP breaker will draw a good amount of current if you tell it to, but why doesn't the CIM wiring dictate what wire is used between the breaker and the speed control?
How does it make sense that I would have to crimp 12 AWG wire to 14 AWG wire after the speed controller to be legal? How does that help?
