I recently installed a air conditioner (window unit) in the addition of my home. It is plugged in to it's own outlet and is not being shared with any other appliances. The outlet tends to get hot when the air conditioner has run for any long period of time, which I can understand. However, there is another outlet approximately 6 feet away, also in the addition, that also gets hot when the air conditioner has run for any long period of time. The only thing that is plugged in to this outlet is my TV. The outlet cools down once the air conditioner has stopped running. Is it normal for this to happen? It is not vibrating (which I know is a sign of arching), it just gets hot when the AC has run for a while. None of the other outlets in this room do this but I am thinking since the 2 outlets are so close to each other this is why this is happening but I just want to be sure. Just to be clear it has been very hot where I live so there are times during the day where the air conditioner may run for over an hour without shutting off. If the air conditioner just runs for 10-15 minutes all seems fine, just seems to be when it has run for an extended period.
Thank you for the information. All the outlets in this room share the same circuit. It is definitely noticeably warm. I contacted my landlord and he said it is normal and not worry but I can't help to be concerned. It is not so hot that it is unbearable to touch but I would not want to keep my hand on it for any more than a few seconds.
The addition is wired to a 15 AMP circuit breaker. In this room I have the AC, TV, cable box and a lamp. The AC is labled to use 8.5 AMPS. It is a 110 V 10,000 BTU unit. I can understand if the outlet that the AC itself is plugged into gets hot after running for any extended period but my concern is that the other outlet that TV is plugged into also gets hot when the AC has run for an extended period.
