Switch socket installation error

With the popularity of home appliances, the number of home outlets has gradually increased. However, if it is not properly installed, it will become an "invisible bomb" buried in the wall. According to relevant survey data from the Ministry of Public Security, in the fire accidents that occurred in China in the past 10 years, fires caused by power outlets, switches, circuit breakers, etc., accounted for nearly 30% of the total number of fires and ranked first in all types of fires.

Myth #1: The location of the outlet is too low Many households feel that they are too high and unsightly when they install the outlet. They will be installed in a lower hidden location. However, Dr. Xia Dong of the Institute of Electrical Engineering of the Chinese Academy of Sciences indicated that it is easy to cause water to splash into the socket when the floor is mopped, resulting in leakage accidents. According to industry regulations, it is better to have a wall-mounted socket not less than 1.8 meters from the ground; concealed sockets should not be less than 0.3 meters from the ground. The sockets for the kitchen and toilet should be at least 1.5 meters above the ground, and the outlet for air conditioning should be at least 2 meters.

Misunderstanding 2: The free installation of the outlet conductors must use a copper cross-section. If you live in an old house, you must replace the original aluminum wire with a copper wire. Because the aluminum wire is easily oxidized, it is easy to light the joint. There have been investigations showing that the incidence of electrical fires in residential buildings using aluminum wires is several dozen times that of copper wires. In addition, many families use slotting and dark pipe laying for aesthetic reasons. Xia Dong reminded that when wiring, we must follow the principle of “into the fire line into the switch, zero line into the lamp” principle, but also set leakage protection on the socket Device.

Misunderstanding 3: The lack of protective measures on the socket There are often water and soot in the kitchen and bathroom. Therefore, it is best to install a splash-proof water box or a plastic baffle on the socket panel, which can effectively prevent the short circuit caused by oil and water vapor intrusion. For families with children, to prevent children from touching with their fingers or metal objects, use a safety socket with a safety flap.

Misunderstanding 4: Multiple appliances sharing the same outlet will overload the appliance and cause fire. Air-conditioning, washing machines, range hoods and other high-power appliances are best to use a separate outlet. In general, it is best to install 4 sets of sockets in the bedroom, a set of 2.5 square meters in the living room, and a set of 1.2 square meters in the kitchen.
