Selection of Wire Material: Single strand wire is widely used at present, but there are also differences between "single core wire" and "multi-core wire". The latter is relatively high in price, but construction, maintenance, replacement and service life are incomparable with "single core wire". It is recommended that customers with economic conditions adopt it. For the selection of flame retardant pipes, it is not necessary to be too luxurious, nor to use those inferior materials which are "flat when pinched". Before construction, it is necessary to check the flame retardant capacity of the selected flame retardant pipes, burn more and see the situation of fire and smoke.

所有走线都必须能拉得动（如果验房的时候细心一点，会发现开发商走的所有线都能抽得动，就是方便维修），如果不能抽动，将来就无法维修，如果这个房子准备住个10年，线路基本上要考虑维修。这一条还防止装修队在开槽时，有的地方偷懒，少pvc放管，尤其是拐弯，连接管的地方，直接就用水泥封到墙里了。如果你家所有的走线都能拉得动，不管是强电还是弱电，将来换个网线、音响线，或者增加这些线路都很方便。

All routes must be able to pull (if you are careful when checking the room, you will find that all the lines taken by the developer can pull, that is, easy to repair), if not pull, it will not be able to repair in the future, if the house is ready to live for 10 years, the line basically needs to consider maintenance. This article also prevents the decoration team from slacking off in some places when slotting, and fewer PVC pipes, especially in turning and connecting pipes, are sealed directly into the wall with cement. If you can pull all the wiring in your home, whether it's strong or weak, it's convenient to change the wiring, audio wiring or add these wiring in the future.

所有走线中不能有接头，否则，时间一长就会引起轻微打火，导致的结果就是屋子里的灯经常性损坏。走线的时候，业主应该在边上，否则检查时已经看不到了。

There can be no connectors in all wiring, otherwise, a long time will cause a slight lightning, resulting in frequent damage to the lights in the room. When walking, the owner should be on the edge, otherwise it will not be seen when checking.

线槽开设：在确定开关插座位置以后，的施工人员会用墨斗线表示出线路走向，然后用切割机械或者手工将线槽开出，线槽深度不可低于4公分，动力线路和信号线路应该相隔较大距离，一般不少于20公分，这样可尽量回避信号线的信号损失。

Wire groove opening: After determining the position of switch socket, professional constructors will use ink bucket lines to indicate the direction of the line, and then use cutting machinery or manual to open the line groove, the depth of the line groove should not be less than 4 cm, power lines and signal lines should be separated by a larger distance, generally not less than 20 cm, so as to avoid signal loss of the signal line as far as possible.

电路改造必要根据电器使用情况考虑进行线路增容。

Circuit modification should be based on the use of electrical appliances to consider line capacity increase.

电工规范中，要求埋暗管必须用PVC管或铁管，有接头的地方必须留面板，以备检测用。

In the electrical code, it is required to use PVC pipe or iron pipe for buried pipes, and the panel should be left where there are joints for testing.

电路的设计一定要详细考虑可能性、可行性、可用性之后再确定。注意强弱电线不能在同一管道内，会有干扰。插座离地面一般为30CM，不应低于20CM,开关一般距地130CM。

The design of the circuit must be determined after considering the possibility, feasibility and usability in detail. Note that strong and weak wires can not be in the same pipeline, there will be interference. The socket is generally 30CM away from the ground, not less than 20CM, and the switch is 130CM away from the ground.

在超市装修中，水电工程是一件非常复杂的事情。因为它直接关系着超市未来经营中的安全问题，所以在装修过程中要非常严格的把控各个环节，同时施工人员的操作过程也要完全符合规范。在超市装修电路施工过程中，施工人员绝对不能徒手操作，需要用的的工具很多，像家庭常见的卷尺、螺丝刀、绝缘胶布，还有很多不常见的工具。了解电路施工中的每种工具的用法和用途，无论是自己还是监工都能顺利操作。

In supermarket decoration, hydropower project is a very complex matter. Because it is directly related to the safety problems in the future operation of supermarkets, so in the process of decoration, we should strictly control all links, and the operation process of the construction personnel should fully comply with the norms. In the process of construction of supermarket decoration circuit, the builder must not operate by hand. There are many tools needed, such as tape measure, screwdriver, insulating tape, and many unusual tools. Understand the use and use of each tool in circuit construction, whether it is their own or supervisor can operate smoothly.
