House decoration electrician how to wiring

Precautions for cable wiring in house decoration With the continuous improvement of people's living standards, people's requirements for the living environment have gradually changed from the economic and practical to the pursuit of beauty and comfort, and therefore many households have installed the interior of their houses. In the cable circuit wiring, switch and socket arrangement, chandeliers, ceiling fan installation, etc., for the sake of convenience, the pursuit of aesthetics, saving materials, not in accordance with the relevant regulations for the device, coupled with the growing popularity of household appliances, electricity consumption increases, thus laying a hidden danger of accidents. Now the cable wiring in the house decoration should be noted and the relevant requirements are described below. First, you should choose to go through the labor department identified, and with the local government labor department at or above the county level issued "into the network work permit" of the electrician to give you cable routing. Second, the decoration of electrical materials used must be in line with national standards (with ISO9000 * logo, international certification) of the qualified products, such as wires, switches, sockets, leakage switches, lamps, etc.? Third, the specific decoration, should be done:? 1, in your home in the line, must be installed with the current national standard leakage protection device. Because of the leakage switch, once the leakage phenomenon occurs at home, such as electrical appliances shell charged, personal electric shock, etc., the leakage switch will trip, thus ensuring personal safety. 2, indoor wiring, should be the socket circuit and lighting circuits are wired separately, socket circuits should be used with a cross-section of not less than 2.5 square millimeters of single-stranded insulated copper wire, lighting circuits should be used with a cross-section of not less than 1.5 square millimeter single-stranded insulated copper wire. Large-capacity electrical appliances (such as electric water heaters, electric showers, electric stoves, etc.) should be configured according to the capacity of the equipment with independent corresponding large-capacity sockets and circuits. (Domestic electric stove should have a special circuit. (Domestic electric stove should have a special circuit. Domestic lighting circuit should not be connected to the electric stove, because the electric wire of the electric stove is easy to contact with the heater, which may directly or indirectly cause electric shock accident.) When wiring, the plastic sheathed wire or other insulated conductors used should be protected by tubes, and should not be buried directly in the cement or lime stucco layer. Because directly buried in the wall of the wire, the dead in the wall, can not be drawn, pulled out. Once a section of the line is damaged and needs to be replaced, you can only cut through the wall to rewire, and replace the line, there can be no joints in the middle, because the joints are buried directly in the wall, over time, the joints of the insulating tape will deteriorate, and long-term buried in the wall will result in power leakage. In addition, most of the family wiring will not be constructed in accordance with the drawings, will not save the accurate wiring drawings file, if the nails in the wall, it may be buried directly in the wall wire damage, and even nails nailed through the wire caused by short-circuiting, injuries, and even caused a fire. Therefore, be sure to wear pipe protection. 4, socket installation height is generally 1.3 meters from the ground, the minimum should not be less than 0.15 meters, socket wiring, single-phase two-hole sockets, facing the socket of the left hole connected to the zero line, the right hole connected to the phase (fire) line; single-phase three-hole sockets, facing the socket of the left hole connected to the zero line, the right hole connected to the phase (fire) line, on the hole connected to the protection line. It is forbidden to connect the upper hole with the left hole with wires. 5. The installation height of the wall switch is generally not less than 1.3 meters from the ground and 0.15-0.2 meters from the door frame. The wiring of the switch should be connected to the phase (fire) line of the lamps or electrical appliances to be controlled. 6, the power supply fuse can not be replaced by copper wire. Because of the high melting point of copper wire, not easy to fuse, can not play a role in protecting the circuit, should choose the appropriate fuse. Do not pull and connect the wires in the process of decoration do not use rubber paste instead of insulating cloth. 7, after the completion of the renovation should try to draw a cable path map, in order to prepare for future maintenance circuit use. ?1, living room, master bedroom, study, children's room are installed cable TV interface, you can watch cable TV programs individually.

2, where there is an AV outlet can be simultaneously **** enjoy a DVD player (VCR / VCD / DVD) and a satellite TV receiver. This can reduce the purchase cost of the DVD player, thus reducing the cost of updating the DVD player; can reduce the space where the DVD player is placed, and do not have to move the player frequently; there is also the advantage that parents can also control the source of the program to prevent underage children from watching unhealthy content in the room, and the content of its broadcasting is controlled by the parents; in addition to broadcasting satellite television programs to all the rooms through the audio-video system.

3, you can through the master bedroom, study, children's room remote control receiver to control the living room audio, DVD player, electric curtains and other remotely controllable equipment. For example, you can control the playback menu of the movie player in the living room with the remote control in the master bedroom.

4, living room, master bedroom, study, children's room, kitchen, etc. are five types of network cable to reach, you can choose to access the Internet in different locations; but also for the network appliances access to the use of the interface is reserved. Through the network switch, you can form a family LAN, so as to realize the function of resource **** enjoyment, network games, etc. Of course, we can also set up for multiple applications to access the Internet at the same time (if you have a refrigerator that can access the Internet). In the study, there is a cable jack, not only can you use the computer to watch TV, but you may also want to use Cable

Modem later.　　5, living room, master bedroom, study, children's room, kitchen, public bathroom are connected to the phone.

Through the program-controlled telephone exchange, the extensions can realize the internal call, transfer, on behalf of the receiver; can set up the computer operator function; the main telephone can be other extensions of the function limitations and many other functions. We can even achieve the effect of "Hello, here is the home of ※※※※, please press 1 for living room, press 2 for toilet, and dial 0 for ...... to check the number of ......" when someone calls. The effect is to ensure that the owner can receive a call within two steps from any location in the room.

6. Users can adjust and manage each line on demand at any time. For example, parents can cut off the output of any line at any time to ensure that school children cannot use the telephone, TV, computer, etc. during study time; a line can be changed from telephone to data, thus changing the use of the function and so on.

However, such a comprehensive wiring management system can be no control of traditional refrigerators, washing machines can, wiring program involved in the home appliances are only: computers, projectors (or television sets), telephones, motorized screens, TV antennas, motorized curtains, video disc players and so on. If you choose to mold the information appliances connected to the smart home system, including network appliances (such as Haier's network refrigerator, network microwave ovens, etc.) can be achieved throughout the room centralized control.
