Plug & Socket HOT - Why?

Today I had an oil convection electric heater (1500W) turned on in the bathroom to heat up the room before taking a shower, and when I unplugged it, I noticed the prongs of the plug were HOT. Probably like 175°F hot...almost too hot to touch. Then I put my hand on the socket and that was hot, too. Yet the cord to the heater wasn't even warm. If the heater uses 1500W I assume that at 125V my load is about 12A...right? It's an old house but the wiring is modern Romex. None of this matters. The prongs are hot because there is a bad connection between the prongs and the receptacle slots., or possibly between the wires in the walls and the receptacle.** If they're not loose, put in a new receptacle. In 1980, I lived ina building in Brooklyn built in 1930. The heat was broken iirc and I was using a heater in my little bedroom ( I had 6 rooms but slept in what was intended to be the maids room. Something woke me in the morning, and I looked at the foot of the bed and a foot to the right to see 1 or 2 inch flames coming from the plug! I didn't know what to do, but my reflex was to unplug it. Each time I reached for the cord, the girl next to me would pull my arm back. I guess she was scared. I reached again, and she pulled my arm back again. At least three times before I overpowered her. It was like a comedy movie. I think she yelled a little too, in fear. I'm glad I was stronger than she was. The fire went out as soon as I pulled the plug from the wall. it was either hard rubber or bakelite that was burning. There was nothing flammable within a foot of the plug, except maybe if pieces fell off the synthetic carpet could have burnt. The plug was normal but the receptacle was 50 years old. Actually, it wasn't even a twin outlet, only one outlet in the center. (You guys know I don't talk about girls, but this was so on point.) Another thing one can sometimes do is, with prongs that are folded back, carefully so you don't cut your self, put a knife in between the two layers, and spread them apart so they are springy themselves to make up fo for the receptacle slot parts. But this isn't the problme in this case, I'm positive. ** in theory between the prongs and the wires they are connected to, but that couldnt be it. The heat woudn't make it to the part of the prongs that show.) Why would the prongs of the plug and the socket get so hot? Resistance in the plug? (The plug APPEARS undamaged, and we always pull it out by grabbing the plug, not the wire). Should I put a new plug onto the cord? Is it likely there was resistance or a bad connection in the socket? Thanks for any clues. C Remove NOPSAM to email me. Please let me know if you have posted also. |
