With the continuous improvement of living standards, more and more home appliances, natural, power outlets will also increase, but if the outlet is not properly installed, it is easy to become home life in the "invisible bomb", then the outlet is often installed What are the errors?
First, the position is too low
Many households feel that they are too tall and unsightly when installing sockets, and they will be installed in lower hidden places. 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.
Second, free to install
Power 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.
Water and soot are often found in kitchens and bathrooms, so it is best to install splash or plastic baffles on the socket panel. Recommending inexpensive and affordable Sunr waterproof and splash-proof boxes for you
In addition, some decoration companies often make ground wires void when installing three-hole sockets, and even directly connect the ground wires to gas pipelines. Professionals pointed out that these practices are very dangerous. The ground wire is connected to the housing of the electrical appliance. Once the appliance is leaking, it will cause people to get an electric shock.
Fourth, sharing
This will overload the appliance and cause a 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.
Fifth, less loop
There is only one circuit in the old house. Once any circuit is short-circuited, the electricity in the entire room will be paralysed. In general, two or three loops can be selected for the socket, and the kitchen and the toilet are all one way. The air conditioner uses a loop.
