Common mistakes and solutions of wire laying

As we all know, water and electricity is the important project in the decoration, the early stage is not good, after that can be more than time-consuming and laborious so simple, do not be good to bring a few serious safety hidden trouble.

At this point, xiaobian really suggest that we ask about which decoration company water and electricity do better before decoration, here is good, one is good quality, the other is the construction specification.

In case the old master does not understand, how you have to learn more about it, today will talk about some common mistakes in wire laying and solutions, if we see, we must avoid.

1. No wiring layout

We need to confirm that all switch socket position is consistent with the design drawing, the number is correct. When doing circuit planning, air conditioning power sockets, kitchen power sockets, toilet power sockets, other power sockets and lighting power supplies should be designed separately in the same way to avoid a short circuit and affect all electricity consumption. But it should be noted that the total capacity of each sub-route can not exceed the total capacity of the entry line.

2. Only one loop

Not only in the old house, but in many houses today, there is only one circuit in the house, and if any circuit shortens, the power to the whole room goes out.

Suggestion: when laying point line, according to the use area, lighting loop can choose two or three, three to four power socket. Kitchen and toilet each take one route, two to three air conditioning circuits, one air conditioning circuit with two air conditioners at most. In this way, when one of the circuits fails, the other circuits can still supply power normally, without bringing too much influence to normal life.

3. Wire color separation is not clear

Circuit transformation often see "wire color without any specific requirements, as long as the color of live line, zero line, ground line is separate" this wire color arbitrary use of the situation, in the future use and maintenance process there will be safety risks.

In order to make the circuit transformation convenient and save materials, the blue line to do live line and zero line, future maintenance, maintenance master is not easy to find live line and zero line, for maintenance inconvenience, and easy to cause construction safety accidents.

Suggestion: As for the color of wire, it is clearly stipulated in the standard of electrical industry in China. Red is the live line color, blue, green, or black is the null line color, yellow and green is the ground line color. In a housing color standard needs to distinguish clearly, the use of unified color separation installation.

If the installed lines do not have uniform color separation, it is recommended to mark the lines on the left and clearly mark the circuit diagram for future reference.

4. Bend the electric tube directly at the bend

5. The wire is buried directly without casing

Error model

Some irresponsible construction party in the construction of the wire directly buried in the wall, wire without insulation tube set, wire joints directly exposed, so easy to cause safety hazards, in the future life, the wire lack of protection, easy to be bitten off by rats or external damage, and lead to short circuit.

Suggestion: The laying specification of electric wires is clear. The electric wires must be protected by insulation bushing and the joints should not be exposed.

These four principles, we keep in mind oh, in the completion of hydropower, with these four points to check, of course, if you can, to find a supervisor to nature is the most convenient.
