Spark in the outlet: when it is safe and when it is not
Sometimes, when you connect the device to the outlet, you can notice a small blue spark. In most cases, this is a normal event, which is a consequence of the fact that electrons begin to flow into the power cord of the unit. In other cases, however, a claim from an electric outlet can cause a fire or seriously damage the fork. This is important that everyone understands why the electric socket sparkles or causes a closure without warning.
The electricity that feeds the house comes through the lines of transmission, which are connected to the main power grid. Electricity flowing through the schemes of the house works very quickly. Ideally, it should flow through the chain and retreat to the main grid without any breaks.
Electric sockets in your house are connected to this fast -moving stream of electricity and transfer part of the energy to the devices that you connect through them. Electricity enters the device through one spot, charges the device and runs away through another spot. The spark that you notice is usually caused by a sudden attracting current strength to the device. After the electrons begin to flow, the spark is scattered, as well as static electricity.
From time to time, however, the relationship between the output and the electric chain becomes problematic. Electric power can cause thermal energy, and this excess heat can lead to the insulation around the wires melt. After exposing the electric wire, it can come into contact with the metal casing of the outlet or even other chain wire. If the connection is installed, then the electrons are jumping through gaps and forming a spark. Since the connection reduces the estimated distance in the chain, this is often called a short circuit.
A short circuit caused by overheated wiring can not only make your outlet sparkle, but also set fire to something significant in your apartment. Roughly speaking, a short circuit is a common cause of fires. Ideally, any short circuits should provoke the shutdown switch or overload the fuses for several seconds. After the circuit is broken, the electricity should stop flowing and the risk of fire will decrease. However, if at home the general malfunction of the wiring, then the entire chain can overheat and create fire behind the walls. That is why each owner of the apartment must carefully monitor the sparks in the mains, especially when working a number of devices through one chain.
