Most people perceive the appearance of sparks from the socket as a malfunction.
Therefore, it is worth understanding in what situations you should worry about sparks in the socket.
It is worth noting that in most cases we are talking about physical processes that do not pose any danger.
When the plug contacts come close to the socket contacts, a charge may appear, which is transmitted through the air. This is a natural phenomenon. Streams of charged particles in this case do not pose any danger.
The plug most often starts sparking when it is pulled out of the socket. This is easy to explain, since the current remains in the device, and it is this that causes the breakdown. If a spark appears when connecting, you should pay attention to the contacts. Perhaps the contacts in the socket have become loose or the parameters of the plug are not suitable.
Each person should clearly understand that the contacts do not close instantly. And when a small blockage remains, a spark appears. There is no point in worrying in this case. Although experienced electricians recommend inspecting the socket and replacing it if necessary.
Often the problem appears when modern devices are inserted into old sockets. And if we consider tees and other adapters, the physical process occurs regularly. Important advice: it is better to refuse tees and extension cords, as they pose a real danger.
If a crackling or other strange sound appears after the spark, this is a reason to pay attention. Any crackling indicates that the contacts are not tightly in contact with each other. In this case, the likelihood of overheating of the wiring and even a fire increases significantly.
If any sounds appear, you should take immediate action. Such a socket can be a real danger.
It is also worth noting that with such a malfunction, the circuit breakers may not work.
