Electric appliance plugs get hot on high wattage appliances that heat up?

When I plug the toaster oven in, or the space heater, or the high setting on my hair dryer, the electrical plug on the appliance heats up in a few minutes as I can tell when I unplug it and feel the metal prongs hot. The low setting of the hair dryer doesn't do this, or the slow cooker, or lamps. Any idea what's wrong with the wiring here? Thank you and bless you for any input!|||Because these are high wattage appliances, they also require a larger amount of current (amps). Anytime wire conducts electricity, heat is generated. The more current, the more heat generated by the wire.





It is the job of the wire insulation to withstand this heat and still protect from short circuit and electrocution. On these appliances, the wire insulation tends to be better and thicker than an average table lamp (that only uses 75 watts). If the wire/plug is a little warm, it is fine. If it is hot, it may not be making a good connection inside the receptacle. This indicates a worn out receptacle that should be replaced.|||Your apparent awareness of wattage on heating appliances gets you down the road and around the corner from many consumers. Since the typical residential receptacle circuit is 15 amps, I'm wondering if you have more than one of these things plugged into the same circuit. Calculate the total watts load, divide by 120, and don't exceed around 12 (amps). And avoid extension cords unless 14g.





If you have an older house, with fuses instead of breakers, and/or "2 hole" outlets, but like the place and plan to stay, get a licensed electrician to give you a bid on upgrading to three-wire service with a breaker panel. Assuming your roof is good, it will be some of the best money you ever spent.|||You need to replace the outlets.





I have heard it said all outlets that get used should be replaced at least every 10 years. Most people fail to do that.





The connections inside the outlet grab the prongs and over time and from warming during use they become weaker. As they get weaker the connection has greater resistance and resistance equals more heat. Eventually a weak outlet will start burning the prongs on the plugs.





Good Luck.|||First you must check for loose terminations at your socket outlet.To do this turn off the power at your fuseboard.Remove the screws holding the socket to the backbox,and check for loose terminations,The cable size should also be checked,this can be done by a qualified electrician.|||maybe you should have someone check your wiring before you have a fire there
