What are the 8 principles of home improvement circuit wiring to avoid potential safety hazards, whic

Circuit construction has already told everyone a lot, today or to talk about the heart, circuit pavement is an extremely important project in the building decoration, it not only endangers the use of electrical appliances, and is closely related to their life safety. Kangjia and so on, let's share with you the eight principles of circuit construction.

Principle. 1. Circuit design, decoration and renovation has always been the key to interior decoration, and there are non-standard wiring and construction that will endanger the normal life after moving in in the middle and late stages. Circuit wiring is a concealment, horizontal is the basic requirement, we should be in accordance with the principle of wiring construction, at the same time need to pay attention to follow the construction principle.

Principle. 2. The spacing between the electric pipe and the natural gas pipe or gas stove shall comply with the regulations. Because the air is flammable, spark discharges can occur in the circuit, and although the risk is not very high, it is important to ensure that safety is as safe as possible.

Principle. Third, the selection of the intermediate interval of strong and weak electricity should be suitable, and weak current is very easy to affect the weak current system. There will be a bad network, unstable mobile phone signal, unusable TV, and the interval should not be too large, especially for rooms with small indoor space, which will consume indoor space.

Principle. Fourth, the lighting fixtures, power sockets, air conditioners, electric water heaters and other circuits in different areas of home furniture should be separated from the distribution cabinet and separated wiring, even if part of it must be cut off for maintenance, it will not endanger the normal use of electrical appliances in other places.

Principle. Fifth, the bathroom floor can prevent the paving of wires as much as possible, the reason is very simple, the bathroom floor is often stored in the middle of the water, although there is a moisture-proof layer of maintenance, but we may cause the risk of leakage to the wires.

Principle. Sixth, all transmission lines must have safety precautions technical measures, hard insulation hose exposed transmission lines need to be maintained with plastic hoses, especially in the kitchen smoke moisture in the kitchen is too heavy, it is very easy to cause serious erosion of the wire skin, cast-in-place plate and open piping there is no certain spacing, plastic pipe can have the effect of ecological environmental protection of the transmission line.

Principle. Seventh, the socket wire paving to carry out color matching, the general use of the zero line of the live wire is bright red, the zero line is dark blue, the grounding wire with two-color wire. In that way, we can distinguish between the neutral line and the live line in the work, which can facilitate future maintenance.

Principle. 8. The wire diameter should be able to carry out scientific and standardized design scheme selection according to the total power of the safe electrical machinery and equipment in the control circuit, and the wire diameter cannot be rashly clarified under the condition of uncertain power consumption. If the wire diameter selection method is incorrect, there will be power jumps and fire in the middle of the route.

Home improvement circuits are more common, but they are also more complicated, because most of the current home improvement circuits are buried in the wall, once the design is improper, it is a very troublesome thing to chisel the wall and replace it. Therefore, it is necessary to understand a certain home improvement circuit design! The design of the circuit must take into account the possibilities, feasibility, usability, and flexibility of the circuit in detail.

Summing up a relatively simple principle: considering connecting a plug-in board in the future in a location where the electrical plug is more concentrated is often better than setting up a socket with a full wall.

Safety hazards to be avoided in home improvement circuit wiring:

1. The distance between the wire pipe and the gas pipe or gas stove should meet the requirements.

2. The spacing between strong and weak current should be appropriate, and strong current is easy to interfere with weak current.

3. The lighting, sockets, air conditioners, water heaters and other circuits in different parts of the home should be separated from the distribution box and wired separately, even if some of them need to be repaired, it will not affect the normal use of electrical appliances in other places.

4. The bathroom floor can avoid laying wires as much as possible, the reason is very simple, there is often water between the bathroom floors, although there is a waterproof layer of protection, but we are still likely to cause water seepage to the wires and cause danger.

5. All wires must have safety protection technical measures, and the exposed wires of hard insulated conduits need to be protected with hoses, especially in the kitchen and bathroom, the oil smoke and humidity are heavy, which is easy to cause serious corrosion to the wire skin, and the roof is not at a certain distance from the open pipe, and the plastic hose can play the role of environmental protection wires.

6. When the socket wire is laid, the color separation should be carried out, and the general use of the live wire is red, the zero wire is blue, and the ground wire is two-color wire.

7. The wire diameter should be scientifically and reasonably designed and selected according to the total power of the electrical safety equipment in the control loop, and the wire diameter cannot be arbitrarily determined under the condition of uncertain power consumption. If the wire diameter selection method is incorrect, there will be tripping and the problem of ** between lines.

It is necessary to pay attention to the selection of wires, and must pay attention to safety issues, pay attention to the problems of ground wires, pay attention to installation problems, and do not have flammable materials to avoid danger.

The first process of decoration is "wiring". In the process of decoration in our living room, Chang Qiaoliang often ignores the comprehensive consideration of power wiring, resulting in unreasonable wiring or leakage of cloth; And with the rapid development of the economy, the power wiring in the original construction is far from meeting people's needs. So how are home improvement circuits wired?

Below we will bring it to youIndoor circuit wiring

1. Material selection.

If you are decorating an old house, the original aluminum wire must be replaced with copper wire, because the aluminum wire is very easy to oxidize, its joints are easy to ignite, according to the survey, the incidence of electrical fire using aluminum wire is dozens of times that of copper wire. If the picture is trouble-free, or it is disgusting to change the key to change the line and affect the appearance. Only replace the switches and sockets, which will bury potential safety hazards for the residents' future electricity filial piety.

2. Wire cross-section.

From the perspective of electrical safety, the national residential design code stipulates that the cross-section of the branch circuit is not less than. It is best to take a 4 line for high-power appliances such as air conditioners, and if you take into account the surge in the types and quantities of kitchen and bathroom appliances in the future, it is best to use 4 copper coins for the circuit of the kitchen and bathroom.

3. The number of circuits.

An adequate number of circuits is essential for modern home life. Once a short circuit or other problem occurs in one line, it will not affect the normal operation of other circuits. Depending on the area used, the lighting circuit can be two or three ways, and the power socket can be three to four ways.

There is one route for each kitchen and bathroom, two or three air-conditioning circuits, and a maximum of two air-conditioning circuits for one air-conditioning circuit.

4. Wiring.

In order to be beautiful and easy to inspect and replace, the way of slotted buried wire and dark pipe laying is generally adopted, and the principle of "live wire into the switch, zero line into the lamp head" should be followed in the wiring process.

The above is how to wire the home improvement circuit for you? The whole story of the principles of indoor circuit wiring.

The circuit engineering of home decoration is the safety guarantee of the daily life of the whole family, and a reasonable circuit can not only ensure the personal safety of the whole family, but also greatly improve our quality of life. But did you know? In fact, there are strict requirements for home decoration wiring, so let's take a look at it today.

1. After the distribution box is metered, it should be wired and powered according to the different Gongchang and Yinchang rates of indoor electrical equipment; High-power household appliances should be independently wired and installed with sockets.

2. When wiring, the color of the phase line and the neutral line should be different; The color of the phase line (L) of the same residence should be uniform, the zero line (N) should be blue, and the protection line (PE) must be yellow and green.

3. The resistance between the wires and between the wires to the ground must be greater.

4. All weak electronic systems use a star structure.

5. 2 3 inlet threading pipes are introduced into the household information access box from the outdoors. The outgoing cable conduit runs from the household information box to each indoor information socket. The laying of dark pipes (threading pipes) should be made of steel pipes or flame-retardant rigid PVC pipes (rigid PVC pipes).

6. The diameter utilization rate of the straight pipe should be 50% 60%, and the diameter utilization rate of the elbow pipe should be 40% 50%.

7. When there are local interference sources on the route, and the minimum clear distance requirement cannot be met, steel pipes should be used.

8. The straight laying length of the dark pipe is more than 30 meters, and the wire box should be installed in the middle.

9. When the dark pipe must be bent and laid, the routing length should be 15 meters, and there should be no S bend in the section. When bending more than 2 times in a row, a wire box should be installed. All turns are done with a pipe bender and are standard turning radius.

It is not allowed to use the three links and four links that are expressly prohibited by the state.

10. The bending radius of the dark pipe shall not be less than 6 10 times the outer diameter of the pipe.

11. There shall be no various cable joints in the dark pipe hole.

12. When wiring the power line, the cross-sectional area of the wire used should meet the maximum output power of the electrical equipment.

13. The parallel distance between the wire and the heating, hot water and gas pipe should not be less than 300mm, and the crossing distance should not be less than 100mm.

14. The joint that penetrates the piping guide wire should be located in the junction box, the joint lap should be firm, and the tin-shabu should be wrapped evenly and tightly with insulating tape.

Circuit wiring is an important concealed project, and the wiring process is relatively complex, and it is easy to have some potential safety hazards when used. Therefore, the circuit should be strictly in accordance with the specifications when wiring, so what are the standards for home improvement circuit wiring? You'll know after reading the following.

Home Improvement Circuit Wiring Standards.

1. Positioning: First of all, the circuit positioning is carried out according to the use of the circuit, such as: to arrange switches, sockets, and lamps, and the electrician will locate according to your requirements.

2. Slotting: Then according to the positioning and circuit direction, start to arrange the trunking, the slotting is particular, and it must be horizontal and vertical. However, it is necessary to open the horizontal groove as little as possible, so as not to affect the bearing capacity of the wall, and the yardage of the deep rock should be consistent, mostly at 10mm, and the groove line is required to be straight.

3. Line pipe: There are two kinds of line pipes: cold-bent pipes and PVC pipes, cold-bent pipes are easy to bend without breaking, which is the best choice for wiring, and its corners have arcs, and the lines can be replaced at any time.

4. Elbow: The cold bent pipe should be installed with a bending tool, and the pipe should be arranged first, and then the steel wire should be used to pass through it, so as to facilitate the maintenance of the line in the future.

5. In order to prevent signal interference, the distance between strong and weak currents should be kept at about 500mm, and if the standard is not reached, the weak current should be shielded.

6. The strong and weak currents of the home improvement circuit cannot be worn in the same tube.

7. The wires of the same circuit should be penetrated into the same pipe, and the total cross-sectional area of the wires should not exceed 40% of the cross-sectional area in the pipe.

8. The socket panel of the first and TV in the same room should be installed at the same height, and the horizontal distance between the power cord and the TV cable should not be less than the distance of a cassette.

9. The PVC pipe should be fixed with a pipe clamp, the joint must be matched with a joint, and then glued with PVC glue, and the elbow should also be bent with a spring.

Summary: The above is about the relevant content of the home improvement circuit wiring standard, I don't know if you understand! Home improvement circuit wiring is a very important project, which is related to the safety of the whole family, so we must master the circuit wiring standards.

Specific principles of wiring:

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

Second: strong and weak electricity cannot be worn in the same tube.

Third: the total cross-sectional area of the conductor in the pipe should be less than 40% of the cross-sectional area of the protective pipe, such as 20 pipes with a maximum of 4 square wires.

Fourth: use the whole pipe as much as possible for long-distance line pipes.

Fifth: If the line pipe needs to be connected, it should be connected with a joint, and the joint and pipe should be glued well.

Sixth: If there is a line pipe on the ground, it should be protected immediately to prevent it from cracking and affecting future maintenance.

Seventh: when the wiring length is more than 15m or there are 3 bends in the middle, a junction box should be installed in the middle, because when disassembling and assembling the wire, it is too long or bent too much, and the wire cannot pass from the conduit.

Eighth: Under normal circumstances, the wires should be more than 1000px away from the gas pipeline.

Ninth: Under normal circumstances, the installation of air conditioning sockets should be more than 2m above the ground.

Tenth: Under the premise of no special requirements, the socket installation should be 750px height above the ground.

Eleven: The switch and socket face the panel, and the live wire switch and socket on the left side should be the neutral line on the left and the right side of the live wire should be facing the panel, and the live wire on the left side should be on the left side and the right side of the live wire.

Twelve: In home decoration, wires can only be connected together.

Thirteen: the joint adopts the press wiring method, which must be strong and firm.

Fourteen: The connected wire should be wrapped with insulating tape immediately.

Fifteen: After determining the color of the live wire, neutral wire, and ground wire, as well as the wires and wire pipes with different functions, the colors can not be confused.

Sixteen: lighting, sockets, air conditioners, water heaters and other circuits in different areas of the home should be separately grouped and wiring, once which part needs to be off-duty maintenance, it will not affect the normal use of other electrical appliances.

Seventeen: After the circuit is completed, leave the circuit layout diagram to facilitate future maintenance, wall trimming or nailing on the wall to prevent the wire from being damaged.

Home wiring considerations.

1. Standardized construction can ensure the use of weak electricity in home decoration now and in the future, and will not destroy the decoration because of new applications in the future;

2. Unified control and management are adopted, and it is very convenient to use, manage, maintain and expand in daily life in the future;

3. The system compatibility is very good, and the network wiring in the system can not only support the network, but also support the security alarm, and the scalability is strong;

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 jumper in the information access box can form a path.
