Mistakes in the use of sockets

With the popularity of household appliances, the number of power sockets in the home has gradually increased. But if installed improperly, it will become a "stealth bomb" buried in the wall. The relevant survey data of the Ministry of Public Security shows that among the fire accidents that have occurred in Our country in the past 10 years, the fire caused by the short circuit of power sockets, switches, circuit breakers and other reasons accounts for nearly 30% of the total, ranking first in all types of fires.

Position too low

When many families install sockets, they feel that it is too high and unsightly, so they will be installed in lower hidden positions. However, Dr. Xia Dong of the Institute of Electrical Engineering of the Chinese Academy of Sciences said that it is easy to splash water into the socket when mopping the floor, which will lead to leakage accidents. 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 in the kitchen and bathroom should be at least 1.5 meters away from the ground, and the sockets in the air conditioner should be at least 2 meters above the ground.

Install at will

Power conductors must use copper cross-sections. If you live in an old house, be sure to replace the original aluminum wiring with copper wiring. Because the aluminum wire is easily oxidized, the joint is easy to catch fire. A survey has shown that the incidence of electrical fires in houses using aluminum wires is dozens of times that of copper wires. In addition, many families use the method of slotted buried wire and hidden pipe laying for the sake of beauty. Xia Dong reminded that the principle of "the live wire goes into the switch and the neutral wire goes into the lamp holder" must be followed when wiring, and leakage protection should be provided on the socket. device.

Lack of protection

There are often water and oil fumes in the kitchen and bathroom, so it is best to install a splash-proof water box or a plastic baffle on the socket panel.

In addition, some decoration companies often make the ground wire useless when installing the three-hole socket, and even directly connect the ground wire to the gas pipeline. Professionals pointed out that these practices are very dangerous. The ground wire is connected to the housing of the electrical appliance. Once the electrical appliance leaks, it will cause electric shock.

Shared

This practice can overload electrical appliances and cause fires. 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.

Fewer loops

The old house has only one circuit, and once any line is shorted, the electricity of the whole room will be paralyzed. Generally speaking, two or three loops can be selected for the socket, the kitchen and the bathroom each go one way, and the air conditioner uses one loop.
