(Summary description)①The position is too low When installing sockets in many families, they feel that they are too high to be aesthetically pleasing, and they will be installed in a lower concealed position. However, Dr. Xia Dong from the Institute of Electrical Engineering of the Chinese Academy of Sciences said that it is easy for water to splash into the socket when mopping the ground, which may cause an electric leakage accident. According to industry regulations, the distance between the exposed socket and the ground should not be less than 1.8 meters; the distance between the concealed socket and the ground should not be less than 0.3 meters. The sockets of the kitchen and bathroom should be at least 1.5 meters above the ground, and the sockets of the air conditioner must be at least 2 meters above the ground. ②Install at will The power wire must use a 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 very easy to oxidize, the joints are easy to catch fire. A survey has shown that the incidence of electrical fires in residential buildings that use aluminum wires is dozens of times higher than that of copper wires. In addition, in order to be beautiful, many families will use slotted and buried wires and concealed pipe laying methods. Xia Dong reminds that the principle of "live wire into the switch and neutral wire into the lamp holder" must be followed when wiring, and leakage protection should be provided on the socket. Device. ③Lack of protection There are often water and oily smoke in the kitchen and bathroom, so it is best to install a splash-proof box or plastic baffle on the socket panel. In addition, when some decoration companies install three-hole sockets, they often leave the ground wire empty, and even connect the ground wire directly to the gas pipe. Professionals pointed out that these practices are very dangerous. The ground wire is connected to the electrical shell.

It is best to use independent sockets for high-power electrical appliances such as air conditioners, washing machines, and range hoods. Generally speaking, it is best to install 4 sets of sockets in the bedroom, one set per 2.5 square meters in the living room, and one set per 1.2 square meters in the kitchen. ⑤Less loops The old house has only one circuit.

However, due to the large jacks of this type of socket, the contact area between the socket tabs and the electrical plug is too small, which easily causes the contact tabs to overheat and cause fire accidents. Two-core sockets are easier to distinguish from the appearance. All products with three-pole sockets on the plug-in board, but only two pins on the plug that comes with the socket, are two-core problem sockets. This type of socket lacks a ground wire. During use, once an insulating component inside the appliance is damaged, the current will cover the entire surface of the appliance. Since the current cannot be introduced into the ground through the two-core socket, it is very easy to cause an electric shock.
