After the circuit is

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.
