with the popularity of household appliances, the number of power sockets at home is also gradually increasing. However, if the decoration is not installed properly, it will become a "stealth bomb" buried in the wall. According to the relevant investigation data of the Ministry of public security, the fire accidents caused by the short circuit of power sockets, switches and circuit breakers account for nearly 30% of the total fire accidents in China in the past 10 years, ranking first among all kinds of fires

myth 1: the socket position is too low

when installing sockets, many home decorations feel that too high is detrimental to beauty, and will be installed in a low hidden position. However, Dr. Xia Dong from the Institute of electrical engineering of the Chinese Academy of Sciences said that it was easy to splash water into the socket when dragging the floor, resulting in leakage accidents. According to the industry regulations, the distance between the open socket and the ground should not be less than 1.8 meters; The concealed socket shall not be less than 0.3m from the ground. The sockets of kitchen and bathroom should be more than 1.5 meters away from the ground, and the sockets of air conditioner should be at least 2 meters away

Myth 2: install the socket wire at will.

the power wire must use the copper wire cross section. If you live in an old house, you must replace the original aluminum wire with copper wire. Because the aluminum wire is easily oxidized, the joint is easy to ignite. An investigation has shown that the occurrence rate of electrical fire in residential buildings using aluminum wire is dozens of times that of copper wire. In addition, for the sake of beauty, many families will adopt the method of slotting and burying wires and laying concealed pipes. Xia Dong reminded that when wiring, we must follow the principle of "live wire into the switch, zero wire into the lamp cap", and also set leakage protection devices on the sockets

myth 3: sockets lack protective measures

experts remind that there are often water and oil fumes in kitchens and toilets. Therefore, it is best to install splash proof boxes or plastic baffles on the socket panels, which can effectively prevent short circuits caused by oil and water vapor intrusion. For families with children, in order to prevent children from touching or stabbing the socket eyelet with their fingers or metal objects, they should choose a safety socket with a safety shield

in addition, some decoration companies often make the ground wire useless when installing three hole sockets, and even directly connect the ground wire to the gas pipeline. Xia Dong pointed out that these practices are very dangerous. The ground wire is connected to the electrical shell. Once the electrical leakage occurs, people will get an electric shock

myth 4: there is only one circuit

the old house has only one circuit. Once any circuit is short circuited, the power consumption of the whole room will be paralyzed. Generally speaking, two or three circuits can be selected for the socket, one for the kitchen and one for the bathroom, and one for the air conditioner

myth 5: multiple appliances share the same socket

experts say that this practice will overload the appliances and cause a fire. It is best to use independent sockets for high-power electrical appliances such as air conditioners, washing machines, range hoods, etc. Generally speaking, it is best to install four sets of sockets in the bedroom, one for every 2.5 square meters in the living room and one for every 1.2 square meters in the kitchen
