Detailed description of Integrated Wiring Construction Specifications

During the design of integrated wiring construction specifications, problems such as circuit transformation process, construction points, and how to choose materials are often encountered. Here we will introduce the solutions and precautions for these problems, hope to help you.

During the decoration process, many owners and decoration companies have attached great importance to the construction quality and effect of "bricklayer" and "bricklayer", but they do not know that they will have the greatest impact on future use, the installation of indoor wires, telephone lines, and cable and television cables is safe and reasonable. Because the new lines are built on the original power line or lighting line, the connection between the two must be strong. Otherwise, it may cause poor contact, both the service life and personal safety of household appliances and lamps will be affected. In addition, pay special attention to the zero line and ground line location do not get wrong, otherwise it will frequently trip, or even burn the electric appliance.

1. Circuit transformation process:

1. Draft the wiring diagram.
2. dashes. Determine the socket, switch, and Panel of the line terminal, and draw accurate positions and sizes on the wall.
3. slotted.
4. embed hidden boxes and lay PVC cables.
5. threading.
6. Install the switch, panel, various sockets, strong weak electrical boxes and lamps.
7. Check.
8. Complete the Circuit Wiring Diagram and submit it to the company for record filing.

II. Key Points of Integrated Wiring construction specifications for circuit Transformation:

1. design the construction specifications of integrated wiring, and implement the principle of strong electric power going on, weak current going down, horizontal and vertical, avoiding crossover, beautiful and practical.
2. the groove depth should be consistent, generally the diameter of PVC pipe + 10 MM.
3. When wiring the power cord, the cross-sectional area of the wires used should meet the maximum output power of the electrical equipment. In general, lighting, socket 5mm2, air conditioning 4mm2.
4. Flame Retardant PVC pipes must be installed for laying underground cables. SG20 tubes for sockets and SG16 tubes for lighting. When the pipeline length exceeds 15 m or there are two right angle bends, a cable pulling box should be added. The lamps on the canopy are fixed with cable boxes.
5. Fixed pipe cards for PVC pipes. PVC pipe joints are equipped with supporting joints, with PVC glue sticking, elbows are bent with spring. Dark box, wire pulling box and PVC pipe with Gong fixed.
6. after the PVC pipe is installed, the cables should be uniformly worn. The same loop wire should be put in the same pipe, but the total number of wires in the pipe should not exceed 8. The total cross-sectional area of the wires should include the Insulation Outer skin) the cross-sectional area should not exceed 40%.
7. the power cord and the communication line must not be in the same pipe.
8. The horizontal gap between the power cord and outlet and the TV line and outlet should not be less than 500mm.
9. The parallel distance between wires and heating, hot water, and gas pipes should not be less than 300mm, and the cross distance should not be less than 100mm.
10. The connector of the incoming pipe wire should be located in the junction box. The margin of the wire head should be 150 MM, the joint lap should be firm, and the insulation tape should be uniformly wrapped and tightly wrapped.
11. When installing the power outlet, the left side of the outlet should be connected with zero line N), the right side should be connected with a phase line L), and the middle top should be connected with a protected ground line PE ). The protection ground is a 2.5-square-color soft wire.
12. When the chandelier has a self-respect of more than 3kg, first install post-embedded parts on the top panel, and then fix the lamps on the Post-embedded parts. It is strictly prohibited to install on wooden wedge and wood brick.
13. When connecting switch and screw lamp wires, the phase line should be switched first. The phase line from the switch should be connected to the terminal of the lamp center, and the zero line should be connected to the thread end.
14. The resistance between the wire and the wire to the ground must be greater than MΩ.
15. The bottom margin of the power outlet should be 300mm, and the bottom margin of the flat switch board should be 1300mm. The height of Wall Mounted Air Conditioning outlet is 1900 MM. Discharge Outlet height 2100 MM, kitchen outlet height 950 MM, hanging disinfection cabinet 1900 MM, washing machine 1000 MM. The TV set is 650 MM.
16. The power supply, telephone, TV and other socket panels in the same room should be on the same horizontal elevation, and the height difference should be less than 5mm.
17. Each household should be equipped with a strong weak electric box, and a Leakage Protector with a working current of 30MA should be set up in the distribution box. After the fractional road is controlled, lighting, air conditioning, and sockets should be controlled separately. The working current of the control should be matched with the maximum working current of the terminal electrical appliance. Generally, the lighting 10A, socket 16A, cabinet air conditioner 20A, and 40-60 A for incoming users.
18. Install the switch, panel, socket and lamp should pay attention to cleaning, should be arranged before the last coated latex paint.

3. How to Choose cables, pipe threading, and switch panel for home decoration:

1. The circuit transformation involves Space Positioning, but also slot, so it should be carried out in advance.

It is strictly prohibited to directly embed the wire into the plastering layer, there is no connector in the wire pipe online, and the pipe wall surface should be smooth, the wall thickness must reach the strength of the fingers, and there should be a qualified certificate. You can also use a special Galvanized Steel Pipe for pipe threading. To comply with national standards, the use of pipe wall thickness of 2mm, the total cross-sectional area of the pipe line must not exceed 40 of the cross-sectional area of the plastic tube.

For example, A 20mm diameter PVC electrical pipe can only wear 5 5mm2 cross-section wires and 4 5mm2 cross-section wires, however, some construction teams wear six or seven 5mm2 or five six 5mm2 wires. The distance between the wires and the gas pipeline is too close, beyond the permitted range specified by the standard; quality acceptance should be carried out at the end of each construction phase in accordance with the standards, and acceptance records should be made. construction teams that do not comply with the general wiring Construction Specifications often do not have acceptance records for electrical concealed projects.

The laying of pipelines follows the principle of "safety, convenience, economy, and objectivity. At the same time, for special power circuits, such as air conditioners, whole bathrooms, and electric showers, it is recommended that the user first check whether there is a protective device when buying, and then configure the corresponding leakage protection switch, to ensure the security of users' property. After the project is completed, it is necessary to conduct leakage detection and provide a complete circuit diagram for future maintenance.

2. Wire Selection:

For fire prevention, maintenance and safety, it is best to choose the "National Standard" plastic or rubber insulation protective layer of single copper wire with the Great Wall logo, the cable trough load area is generally: 2.5 mm² for lighting and socket cables, no less than 4 mm² for air conditioners, green and yellow dual-color cables, and red, white, black, and purple cables for power switches (FireWire. However, the color usage of cables in the same home decoration project should be consistent.

3. selection and installation requirements of switch panel and socket:

The Panel size should be consistent with the size of the pre-embedded junction box. The surface is smooth, the brand logo is obvious, and the Great Wall logo has the anti-counterfeit logo and the national electrical safety certification. When the switch is turned on, the feeling is flexible and the socket is stable, copper must have a certain thickness; the panel material should be flame retardant and rugged; the switch height is generally 1200 to 1350mm, distance from the door frame door is 150 to 200mm, the socket height is generally 200 to 300mm.
