How to wiring and precautions for indoor installation of dark wires

Come as you need. Don't regret it later, it's a hassle to want to add.

The socket may wish to change the holes, such as nine holes, twelve holes, convenient.

Remember to take photos and keep them for later disposal and maintenance.

Don't connect too many wires in one place, it is easy to have problems.

Find a skilled electrician.

It's all from my experience.

1. Select and determine the position of lamps, sockets, switches, etc. according to the renderings and specific construction drawing design drawings, and then determine the laying position of the wire, the position through the wall and the floor, as well as the fixed position of the start, corner, branch, terminal point, insulator or groove plate.

2. Excavate the wall groove according to the direction of the wire, and the width and depth of the groove should be able to bury the wire pipe. At the hole through the wall, the wire pipe should be carefully bent so that it can still be threaded inside after bending, and the wire pipe should be fixed on the wall with a special crimp or riding nail.

3. The position of the socket and switch should be perforated in advance to pre-embedded plastic expansion pipe or wooden wedge.

4. For threading, the formal practice is to use the steel wire to pass through first, and then pull the wire in. In home decoration, the wire can be directly threaded into the sheath pipe, but it is more difficult to pass through the turn, so it is generally threaded at the same time as the plastic pipe is placed, or a lead wire is worn in the plastic pipe in advance.

5. Energize, wait for all the wires to be worn, and connect with switches, sockets, lamps and lanterns for trial power-on, and after proving that the wiring is correct, the chiseled wall will be leveled with cement mortar.

In line with the vertical and not horizontal planing method, so that it is easy to find a position if there is a problem with the circuit in the future. . .

How much special party fee third party Stephen found.

The main point is that it is convenient to replace it in the future, and I have encountered the owner after the renovation and construction, the first line is not good to draw, resulting in the telecommunications company is not good to replace the optical cable.

Indoor installation of dark wiring concealment and precautions are as follows:

1.The circuit setting is unreasonable.

Home decoration is generally set up with 5 to 8 circuits according to the electricity and electrical equipment.

2.Indiscriminate wire specifications.

The wires used in home decoration are single-strand copper core wires, and the wires of each specification are applied to different positions and cannot be used indiscriminately.

3.No private line is set.

Home decoration requires that high-power electrical appliances such as air conditioners and water heaters must be set up with special lines, so as to meet the requirements of electricity load and ensure the normal operation of electrical appliances and electricity safety.

4.The switch is wired incorrectly.

The correct wiring method should be the phase wire of the switch and the zero wire of the lamp head.

5.The socket is wired incorrectly.

The correct wiring method should be the right phase wire, the left neutral wire, and the upper ground wire.

6.The power line and the signal line are laid in the same pipe.

Cause mutual interference with the stove wheel, affecting the use of TV, **, network, audio, etc.

7.If the ground wire of the entire circuit is not set, it will leave a major electrical safety hazard.

When we decorate the living room, in fact, the water and electricity decoration in the whole room is very important, so we must pay great attention to its safety when installing our water and electricity. However, an important point in hydropower installation is the operation of the dark line, because many people do not know how to do it when they do the dark line, so today I will introduce to you what are the draft of the dark line wiring skills? And what are the precautions when making dark lines?

First, dark wire wiring skills.

1. Bedroom wiring.

Generally, the bedroom should be seven lines, respectively, there are power lines, lighting lines, air conditioning lines, TV feeders, lines, computer lines, alarm lines, in addition to we should also reserve the power cord port on the bedside table, which can reduce a certain amount of trouble for the later stage, in addition to reserve the wire port and so on.

2. Wiring in corridors and halls.

As long as there are two routes in the area here, they are lighting lines and power lines, in which the power terminal interface must be reserved for 1-2 interfaces, and the lighting line should be based on the length and area of the corridor to decide what kind of lights to install, if it is relatively narrow, you can install a ceiling light or a translucent glass lamp.

3. Restaurant wiring.

For restaurants, there need to be power cords, lighting cables, air conditioning wires, general power cords have 2 to 3 power terminals, and lighting to choose a warm light source, and the switch also chooses the inside of the door, and the air conditioning should also have professionals to reserve the interface.

4. Kitchen wiring.

For the kitchen, as long as there are lighting lines and power cords, the power cord is very important in the kitchen, choose 4mm2 wire, in addition, with the continuous update of kitchen equipment and the increase of electrical appliances, the customer's requirements for the power cord will be much higher, and reserve a little power supply for later use.

2. Precautions for dark wire wiring.

1. Do a good job of insulation.

After all, the wire is concealed, so we must do a good job of insulation, and keep the construction drawings of the circuit when doing the circuit, which is to use PVC pipe sleeve, and the dark pipe also chooses a good brand of copper core wire, and the specific size can be vertically stared at the blue to refer to the actual needs to choose the wire.

2. Don't play too much trunking.

When we carry out the concealed installation of wires, we should pay attention not to play too much trunking on the load-bearing wall, and also pay attention to waterproofing in wet places.

3. Be prepared for future maintenance.

Generally, a socket is reserved, and then a high-power electrical appliance is reserved in case of backup, and the wire is bought according to the color, such as red, green, blue, etc., which is done to facilitate future maintenance.
