Unusual damage to the cord, burned the extension cords 2 times and almost caused a fire. Figured out the reason

The phone rings, the number is signed, which means that they have already contacted. It turned out that the woman asked her parents to look at the problem, the extension cord on the TV burned out. Strange, it would be okay on a kettle, air conditioner or heaters, there is decent power, but on the TV - a trifle. From the conversation I did not really find out anything, I promised to go in the evening.

What the heck?

Indeed, the outlet block and the plug of the cord are badly charred, the owner has already bought a new extension cord, there is no outlet near the TV. In the conversation, I was immediately alerted to the fact that it was the second extension cord that burned out, and the new one would be the third.

I could not understand why such a problem arose, the power of the miracle of hostile technology is only 380 W, the extension cord is designed for 2000 W, something is wrong here.

I installed the plug on the cord from a burnt-out extension cord, it was in perfect order, but the owner did not buy a new one. Just in case, I checked the TV for a short circuit, everything is normal, and the automatic switches did not work earlier.

He turned on the device and began to check the heating of the plug, cord and outlet block - cold. I began to question the owner in more detail, I wanted to get to the bottom of the truth and not leave behind a delayed-action mine.

What was the problem

It turned out that after the first extension cord was melted, the pins of the plug “burned” and wobbled, it was already unusable. The contact became unreliable, which led to severe overheating and failure.

But notice what are the consequences of such a "trifle", all this happened at night and half a step remained before the fire.
