I have the same problem.. the electric plug in my air conditioning (AC ) feels extremely HOT..…I found it some what helpful if you consider the following :
1) the reason the plug gets hotter than the outlet cause of the Guage of the copper wire in the plug is thinner than the one in the outlet…
* 2) the connection contact in them is weak, thus it creates heat.
* 3) operate the AC on “LOW”…
* 4) GOOD LUCK. …
