Warm and Noisy Electrical Conduit
Turn it off right now. There is probably a loose connection inside that is sparking and likely to start a fire.
Generally the circuit wires from a breaker daisy chain through various outlet boxes along the way. A loose connection where a wire connects to the receptacle (or a switch) is not unusual. It is better to screw the wires on instead of using the "push in and it sticks" holes in the back.
Loose connections have a tendency to get hot and once the wire gets burned, the resistance goes up and it behaves as an even looser connection.
Either that or you are overloading one of the circuits inside that conduit.
It is definitely abnormal for electrical wires to heat up noticeably when you turn on appliances or things.
The disadvantages of crab apple trees. In summer, the apples are too sour to pick and eat. In winter the birds come and leave dropping all over the place.
