From what I have learned about appliances, any time a sheltered cord or plug is hot to the touch from normal use, there is something loose. I would check where it is plugged in, as well as what kind of load you were using. I had a pedestal with a loose connection that I did not notice till I pulled the plug at the end of the week-end. I should have picked up a couple hints, though. The charger cords for our various techie do-dads, were hot, and one did not charge in the normal time. I replaced the end before I plugged it in again at home.
