Personal opinion is that what gets hot in the GMC power cord is the plug.
I've noticed that the plug is warm when running my 1500W heater, and the
cord is ambient temperature.
Of course the plug is normally outside the cord storage area when it's in
use, unless using an extension cord.
The electric coffee maker in our home kitchen is another matter. By the
time 12 cups of water are turned into 12 cups of coffee, both the 2 foot
cord and the plug are too hot to hold comfortably. (Think 2 cents
cheaper to make if they use a cord and plug that are smaller than they
should be.)
