Sparkling outlet in a home or an apartment today is not so rare. If your outlet is beginning to spark you should not hesitate, and it is better to fix the problem. Otherwise there is the possibility of electrical shock or fire formation. Try to understand why the spark plug, and what to do in such a case.
The reasons of sparking outlets
Analyzing the causes of sparking plugs, the following points should be highlighted:
- Using Euro outlet together with the old sample plug;
- Operating wear outlet;
- Poor contact due to easing fork clamps;
- Overcurrent.
Inconsistency plugs and sockets
In Soviet time electrical plug electrodes produced with a diameter of 0.4 mm. Modern Euro plug and receptacle designed for a diameter of 4.8 mm. When the plug is inserted in Soviet Euro socket, there is no intimate contact between the electrode and the contact plug sockets jaws. This is the cause of sparking.
Also there is a reverse situation, when the euro plug is inserted into the Soviet outlet, there is an expansion Bow diameter pin socket sponges. And when a socket is inserted into a common Soviet yoke, again there is no close contact.
Yield: use of appropriate plugs and sockets.
Loss of service life
Whatever the quality was not expensive and outlet, sooner or later it will come a time when its operating condition is poor. Especially quickly come sockets in failure due to the lack of audit.
Arcing can occur due to the formation of deposits on the contact jaws. When the plug is inserted into the socket, instead of tight contact current carrying parts comes into contact with soot, which has a high resistance. And whereby the arcing starts.
The reason may also be a relaxation of the contact wire in place of fastening. Excessive unclamping contact jaws, which does not ensure good contact, is also a cause sparks.
Yield: Replacement or conduct of the audit, depending on the technical and operational condition.
Connecting the included instruments
This situation should consider a specific example. On kettles or other modern appliances have a power button. If she is in a switching position, that at the time of inserting the plug into a power outlet may form sparks, the strength of which will be directly depend on the power of the device.
There are those appliances, which do not have to enable or disable the button. In such a situation, to avoid sparking, must be disconnected from the socket (turn off the power supply breaker), insert the appliance plug into the outlet, and only after a voltage is applied.
Output: Connect appliances in the off position.
Effects
strongly not recommended to delay the repair and restoration of sparkling outlet. Problem appliance at a time can cause a fire, just one spark could be enough to cause a fire.
At risk of fall, not only you, but the people who live with you. Also, do not rely on automatic operation, especially if the audit conducted five or more years ago. The value used is inflammable plastic receptacles, but it easily melts and may simply lock plug of the electric appliance. And if you want to draw it, then you significantly increase the likelihood of electric shock.
