What do we need to do before the circuit transformation?

Whether it is a friend who is decorating or a friend who is already preparing to decorate, it should be known that the circuit renovation in home decoration is indispensable. And because it is related to the use of the house for the next few decades, and maintenance and inconvenience, everyone also values ​​it. The beginning of all things difficult is actually the most important thing for the beginning of everything. In particular, a series of preparations before the circuit transformation is completed. If it is perfect, it will reduce many troubles in the future. The basic process before the circuit transformation is to detect whether the wires are short-circuited or not. Ground marking, measurement and material preparation, the following Xiao Bian take everyone to learn more about it!

First, design the circuit

In the initial design of the circuit, we must seriously consider the feasibility of a good plan. Imagine if the family and myself are living in the future, where do they need electricity? For example, in the living room, there may be more electricity, and the big guys want to watch TV, summer air conditioners, everyone in the living room to play mobile phones to charge, and so on, all need electricity, in this case, Prepare outlet power in advance. When you use too much electricity, you might as well buy a socket directly, and it is safer and more beautiful than a full-size socket. However, we must pay attention to the height of the outlet. Kazakhstan is too low. Anything on the floor will be splashed wet. It is also unsafe for children at home, and it is very likely that it will be blocked by furniture. Therefore, we must consider it in advance.

Second, measure whether the wire is short-circuited before construction

Before the construction, it is necessary to measure whether the wire is short-circuited. Short circuit means that the power supply is directly connected to the closed circuit by the wire without passing through the load. During operation, the power system flows a very large current when an abnormal connection occurs between phases and phases or between phases. Under normal conditions, the resistance between the phase and the phase or between the ground and the ground is very large. When the short circuit occurs, the resistance is substantially zero. It is entirely possible to measure the resistance with a multimeter.

This kind of measurement, it is very difficult to have the chance to measure under the state of conduction, but the circuit is measured and judged very well under the state that is not connected, so must do well in the test before circuit transformation.

Third, the wall surface to mark

In the wall, the ground to go to mark is to more clearly the direction of transformation of the circuit. The cartridge should be used to position the wall before the slot is opened on the wall or floor. The surface of the pipe and the wall should be left with 15mm layer of dust to prevent cracking of the wall. Xiao Bian needs to remind that public electrical facilities such as lightning protection grounds and protective grounding can not be arbitrarily destroyed or changed without permission.
