in the process of new house decoration, many citizens often pay attention to the quality and safety of carpentry and bricklaying, ignoring circuit installation. As everyone knows, the safety performance of these concealed works is more important. Once they are reworked, it will make you uncomfortable. The project is dynamic, time-consuming, laborious and expensive

Mr. Zhao, a citizen who just bought a house in Guanzhuang, moved into his new house for some time, but the phone at home suddenly stopped working. As soon as he made a call, there was a huge noise, which was unbearable. Originally, I thought it was the problem of telecommunications, but people from the telecommunications department came to test it.

at present, in home decoration, water pipes, wires, telephone lines, cable TV lines, etc. are generally buried under the floor or in the wall, covered with cement, and then decorated on the surface. This fully enclosed way has caused many potential safety hazards, and also brought great obstacles to the maintenance of pipelines in the future

in fact, even in the book of commercial housing, there are few introductions to concealed works such as electrical lines. The owner cannot get a complete as built drawing of electrical lines when buying a house, and he does not know the situation of home wiring in the process of decoration. The knowledge of safe electricity use and wiring in the process of decoration can be said to be blank. Therefore, keeping a complete pipeline route drawing is a prerequisite to avoid problems and solve problems in the future, otherwise there is no way to start

at the same time, it must be noted that the construction personnel should hold the electrician's book issued by the relevant national departments to strictly prevent unlicensed construction

experts said that if citizens decorate old houses, the original aluminum wires must be replaced with copper wires. Because the aluminum wire is easy to oxidize, its joint is easy to ignite. According to the survey, the occurrence rate of electrical fire using aluminum wire is dozens of times that of copper wire. If only switches and sockets are replaced, it will lay hidden dangers for residents' future electricity use

in addition, a sufficient number of loops is essential for modern home life. After there are enough circuits, the normal operation of other circuits will not be affected when a short circuit or other problems occur in one circuit. According to the area of use, the lighting circuit can be two-way or three-way, the power socket can be three to four ways, the kitchen and bathroom can be one way respectively, and the air conditioning circuit can be two to three ways. An air conditioning circuit can have two air conditioners at most

relevant tips: wiring mode

in order to be beautiful and convenient for inspection and replacement, slotting, buried wire and concealed pipe laying are generally adopted. Follow “ in the wiring process; The live line enters the switch, and the zero line enters the lamp cap ” Principle of
