What are the wiring precautions for home improvement electricians? Can anyone tell me?

Home decoration wiring is a very important issue. There are many aspects that require wiring. The most common ones are water and electricity wiring. Now there are also network wiring and TV signal lines, etc. Because many friends pay attention to appearance, they all Choose concealed wiring, so wiring is the first step in decoration. The quality of wiring is very critical. Reasonable wiring can make future use more convenient and faster. The wiring steps are relatively delicate. It is recommended that you be sure to check your own wiring before wiring. Plan the layout of the house and figure out where you want the wiring to be.

Home integrated wiring module

Network module

The network module consists of a set of Category 5 RJ45 jacks, which mainly realizes the connection of computer network cables entering the room. Jumper.

Telephone module

The telephone module is actually the same as the data module. It also uses a set of Category 5 RJ45 jacks to multiplex and output the telephone lines entering the room, which is one in and multiple out. , the output port is connected to the telephone socket in the room, and then the socket is connected to the telephone.

TV module

The TV module is actually a cable TV distributor. As shown in Figure 4, this module consists of a professional-grade radio frequency one-to-four splitter.

Planning, design and preparation before installation

Information access boxes are generally installed at the entrance of the house and embedded in the wall. The installation positions of pipelines and sockets are determined according to the user's own living habits and the placement of home appliances and furniture.

How to determine installation materials and quantities

The pipelines are installed under the floor through PVC pipes, and the sockets are hidden on the wall 30 cm above the ground. During the actual installation process, a margin should be considered. Generally, 30CM is left in the concealed box and 50CM is left in the information access box. Assuming that the average distance from various information sockets to the information access box is 25 meters, a simple calculation can result in a refined bill of materials.

Installation steps and methods

Determine the location, pre-embed the box, set up PVC pipes, and pre-embed the concealed bottom box (pass the traction wire through the pipe, There are exposed iron wires at the box and information box), put through various cables, mark them, organize them, tie them (leaving margin), connect and plug in RJ45, RJ11, 75Ω coaxial and other plugs for testing.

Specific principles of wiring:

First: the distance between strong and weak currents should be 750px-1250px.

Second: Strong and weak electricity cannot pass through the same pipe.

Third: The total cross-sectional area of ??the wires in the tube should be less than 40% of the cross-sectional area of ??the protective tube. For example, a maximum of 4 2.5-square-meter wires can be worn in 20 tubes.

Fourth: For long-distance wire pipes, try to use whole pipes.

Fifth: If the wire pipes need to be connected, joints must be used, and the joints and pipes must be glued.

Sixth: If the wired pipe is on the ground, it should be protected immediately to prevent it from being stepped on and cracking, which will affect future maintenance.

Seventh: When the wiring length exceeds 15m or there are three bends in the middle, a junction box should be installed in the middle, because when the wires are disassembled and assembled, they are too long or bent too much, and the wires cannot pass through the wiring tube. .

Eighth: Under normal circumstances, the distance between wires and gas pipes should be more than 1000px.

Ninth: Under normal circumstances, the air conditioning socket should be installed more than 2m above the ground.

Tenth: Unless there are special requirements, the socket installation should be 750px above the ground.

11: When the switch and socket face the panel, the neutral line should be on the left and the live wire on the right. When the switch and socket face the panel, the neutral line should be on the left and the live wire on the right.

Twelve: During home decoration, wires can only be connected side by side.

Thirteen: The press connection method is used at the joint, which must be strong and firm.

Fourteen: After connecting the wires, wrap them with insulating tape immediately.

Fifteen: After determining the colors of the live wire, neutral wire, and ground wire, as well as the wires and wire tubes with different functions, the colors cannot be confused.

16: Lighting, sockets, air conditioners, water heaters and other circuits in different areas of the home must be grouped and wired separately. Once any part needs to be powered off for maintenance, it will not affect the normal use of other electrical appliances.

Seventeen: After completing the circuit, leave a circuit layout diagram to facilitate future maintenance, wall modification, or nailing on the wall to prevent the wires from being damaged.

Precautions for home wiring

1. Standardized construction can ensure the current and future use of weak electricity in home decoration, and will not damage the decoration due to new applications in the future;

2. Using unified control and management, it is very convenient to use, manage, maintain and expand in daily life;

3. The system has good compatibility, and the network in the system Wiring can not only support the network, but also support telephone and security alarms, and has strong scalability;

4. Plug and play, as long as there are new home appliances and information equipment, you can only plug in the corresponding interface and The corresponding jumpers in the information access box can form a path.

Reasonable home wiring will be of great benefit to future life. There are many types of home wiring, mainly TV, telephone and home electricity. Our common switches and sockets must be carefully arranged. For satellite TV, you need to make a careful preliminary plan before installing it. Find the satellite TV at the installation point you need. You can also find professional wiring personnel to assist. For home wiring, you must find a regular wiring organization. The personnel have rich experience and can guarantee The quality of the wiring.
