There are some precautions for the renovation of the circuit of the old house, how much do you know?

If we renovate the waterway circuit when the house is renovated, at this time, it is basically a way to bury the water pipes and line pipes in the wall. It is rare to take the way of surface-mounted line pipe water pipe. When arranging the line pipe, you can not know that it is neat and uniform, which is very beautiful and orderly.

First of all, the lighting line, generally from the top of the ceiling or hidden in the top gypsum line, if the surface, generally along the top surface and the top corner of the wall line, at the switch, from the top corner down the lead switch line.

Basically, these three styles are the mainstay. Then I will now take these three styles of old houses as an example to explain how to take the bright line will not conflict, but can improve the beauty of the old house a little. It is also very beautiful to use open pipe wiring, horizontal and vertical, and has minimal damage to the wall.

Suitable for the renovation of old houses, the decoration of old houses can be used with 20 open line grooves, during the construction process to go to the horizontal and vertical, the place where you need to turn, do not cut directly, cut 45 degrees with a knife, so that it is more beautiful, and the old house line should pay attention to a few points from the new.

In this way, it will be even more beautiful. Note 1: Observe the square number of the main line of the house. There is an old house with an area of 4 square meters of aluminum wire.

It is recommended to replace the meter outlet with 6 square meters of wires, at least 4 square meters of copper core wires. When we arrange the line pipe, in fact, I have a basic principle, which we have to follow, that is, try to adopt the principle of two points and one line to avoid unnecessary turns.

Now many decoration workers will use the top method when making water pipes, but in fact, this is not simply for the sake of the owner, because if the water pipe goes to the top, more materials and budget will be used, and I recommend walking on the ground for normal water circuits, especially in the living room, dining room, bedroom, kitchen, etc., it is generally not recommended to go to the wall to open horizontal grooves. The second is the living room and other dry rooms, about 300 sockets from the ground.

I understand that when doing hydropower transformation, we should pay attention to choosing safer materials, so that it is not easy to have accidents, and we must find professional personnel to do it, which is more safe.

Circuit modification. Change the system. Reserve the line. Keep the drawings that can be retained as much as possible. Change the inscription to underfloor heating. Take a look at pipes and pipelines. It would be nice to do some remodeling on the basis of the original house, or hire a designer to design it.

When transforming the circuit, we must choose a shortcut line, and at the same time, we should also pay attention to the aging of the circuit when transforming, and we should also choose some wires with better quality.

Be sure to find a good line, give a decoration plan in advance, pay attention to safety issues, and turn off the electricity when renovating, and tell the residents in advance.

It is very well understood, and it should be modified by looking at the drawings, and some good circuits should also be used, and the circuits of the old house must be removed so that it is okay.

First of all, it is necessary to check the electrical circuit, check the waterway and carry out appropriate repairs, as well as the air conditioner, high-power electrical appliances, and electrical wiring.

I know a lot, because I've been in charge of renovating a lot of house circuits.

The renovation of the circuit of the old house needs to be comprehensively evaluated and carried out as a whole.

Methods of circuit renovation of old houses:

1. The renovation should be done in one step, the water and electricity of the old house is old, so if the transformation is not as good as one step. Some people like to knock here today and fight there tomorrow. The fundamental problem of water leakage and power outage has not been completely solved, and it seems that it costs less money, but in the end, it actually costs more money.

2. It is best to rearrange all the water and electricity pipes, hydropower is the foundation, and the water circuit of the old house has been aged, so it is best to rearrange all the water and electricity pipes, which requires slotting in the wall and laying water pipes and electric pipes; It is likely to smash walls, whitewash walls, open holes, and so on.

3. Find an experienced hydropower designer for the overall design, the old-fashioned decoration of the old house has obviously not met the electrical appliances of the modern family, for this reason, we must ask an experienced hydropower designer to design it as a whole, and then consider what are the shortcomings, modify and improve. Once the construction of hydropower starts, it is very troublesome to modify it, so be sure to plan ahead.

4. Install distribution boxes, circuit breakers, and careful wiring, many old houses do not have distribution boxes, and use fuses, which are easy to burn out, and some people like to replace fuses with wires, which is easy to cause safety problems. Many old houses are rented, and the safety of rental houses cannot be ignored. Nowadays, there are many electrical appliances, so it is necessary to configure new distribution boxes and circuit breakers, and each room is controlled by separate wiring.

Precautions for the renovation of old house circuits:

1. The usability of water and electricity, in the process of home decoration, hydropower projects account for a large proportion of the decoration budget, generally about 20%. So avoiding impractical cable routing can save you a lot of money.

2. The correctness of the positioning of hydropower, try to shorten the distance of the wiring when the hydropower is routed, and reduce unnecessary waste. At the same time, the bending should be minimized, when the length of the straight line section is more than 20m or the right angle bend is more than three, the middle junction box should be added. Guaranteed future maintenance.

3. The stability of water and electricity, the circuit wiring in the decoration should be protected by PVC pipes, there should be enough distance between strong and weak currents so as not to affect the weak current signal, and the indoor wiring of TV, ** and network cables is not allowed to be connected in series. This also prevents signal interference. This is very important, otherwise there will be problems and problems in the future.

The following points should be paid attention to in the renovation of the circuit of the old house:

Learn about the household appliances to be used in home improvement, calculate the load of the line, and choose the wire reasonably. The general home improvement wire selection is to normally provide 5A per square millimeter for long-term operation.

Take a look at the working current and maximum working current of the household watt-hour meter, and estimate whether the maximum working current of household appliances is within the allowable range of the meter. Prevent the meter from being burned out by the maximum current that exceeds the current for a long time.

Check the cross-sectional area of the wire, if the cross-sectional area is too small, it will affect whether the household appliances can run for a long time, and there may even be accidents such as fire.

Turn on the three-pin socket in the old house to confirm that the house has no ground wire. If there is no grounding wire for an old house, you must not replace the ground wire with a neutral wire.

If all the original wires are replaced, try to use the original threading pipes for the wires. You really can't use the original threading pipe to go to the new pipe. The original interspersed conduit is replaced.

The wires are all live wires, and if you want to change the wires, it is easy to replace. If the new line is added, if a large number of threading elbows are used, the live wire will become a dead line, and the threading pipe can only play a protective role. Once there is a problem with the wire, it can only be replaced by slotting.

The power distribution of the new household switch box must be scientific, and each circuit should be controlled separately as much as possible. Not all outlets can be connected to one circuit.

If the second-hand house is decorated, if there are conditions, the socket must be leaked, which is a major event related to people's lives. In the event of an electric shock, the power supply can be quickly disconnected to protect people's lives.

Maintain the distance between strong and weak current wiring to prevent weak current signals from being interfered by strong electricity.

Finding a professional electrician can give you peace of mind in your home improvement circuit.

It is recommended that all the wires be replaced for the circuit renovation of the old house, and the electrical appliances will be updated to keep pace with the times, which is bound to revolutionize the circuit.

It should be done standardly; After the original dismantling is completed, the overall slotting, pipe routing and threading can be carried out.

The most important thing for household electricity safety is the kitchen and bathroom, look at your description of the local transformation is impossible, the entrance line is a few square you didn't say, how many old houses with lines to not fit the current electricity demand, it is recommended to rearrange all.

It's definitely best to change it all.

Locally, consider wiring the water heater and air conditioner separately.

If it is all copper wire, the lighting can not be moved.

The wiring of the old house is no longer suitable for the current electricity demand, and it is recommended to rearrange all of them.

In general, as long as your electricity power does not increase much, as long as it is in line with your electricity habits and convenience, you can not change the line, if you want to increase the power of electricity then you can divide the air conditioner into a separate line, or rearrange the high-power electrical appliances you want to add a line. You can reinstall a distribution box on your meter offline, that is, the meter comes out and into the home line, and you can install the leakage protector and air switch and the main switch of each line in the distribution box, there is no need to change it. The distribution circuit is completed in the distribution box (e.g.

After your home line passes the air switch and leakage protector, you can control all the lighting lines with a master switch, the air conditioning line with a master switch, and the high-power induction cooker, refrigerator, and water dispenser line with a master switch. 5(30)a, 5a, on the meter indicates the base current of the meter. It is a benchmark for meter inspection, testing, and this parameter is meaningless for the user.

The 30A in parentheses indicates that the maximum current of long-term operation is 30A, and if the current exceeds 30A, the meter will burn out, that is, the maximum current of your home cannot exceed 30A. If your current circuit layout does not meet your electricity habits and is very inconvenient to use, then you can also change it.

You's**? You can only be sure if you have seen it on the spot.

The conversion of water and electricity in an old house or an old house is more troublesome than the renovation of a new house. Because the house is very old, the wiring has been aged, especially for the old house for more than 20 years, many wires are aluminum core wires, which is difficult to carry high load voltage. As the quality of life gets higher and higher, the average family has more and more electronic products, new home appliances, and smart devices, which provide convenience while also increasing the requirements for the capacity of the room.

There are limitations in the number of socket switches and pipe layout in the old room, so it is necessary to convert the water and electricity layout of the old room to fully consider and ensure the convenience and safety of our life. So what do we need to pay attention to?

The quality of the material is best to choose brand materials, the quality is relatively high, and it can be used with peace of mind. The material of the electrical line is usually PVC. It is better to use materials with flame retardant properties, which are safer; The PPR pipes used in the waterway have hot and cold water pipes.

The lighting socket wire is not less than the copper core wire, and the air conditioning pipeline is not less than 4mm2 copper core wire. The copper core wire is very small, has good conductivity, good heat dissipation, small loss, large current carrying capacity, convenient and corrosion resistance, and the construction is very ideal.

Waterway renovation. Water supply structure: The water pipe should be laid horizontally and vertically, and the pipe clamp should be fixed.

The cold water pipe from the distance from the wall is based on the design and choice of fixtures. The various valve installations should be correct and flat, and the hot and cold water valves should be of the same height, with the left side being cold. Except for another design requirement, all water pipes must be buried in walls or floors and must not be exposed.

After installing the water supply pipe, the pressurization test is pressed in without leakage.

Drainage structure: The drainage must be securely installed to ensure that the pipes are not blocked and there are no leaks. Once the construction of the drain pipe is complete, it is necessary to protect the pipe with a protective cover before installation, preventing the duct air outlet from using foreign objects in the subsequent structure.

Shower enclosures and cabinet sinks must be fitted with separate plumbing.

Circuit transformation. Weak electrical structure: When building with 380V power cords, the strong and weak conduits should be more than 50 mm, such as strong wire intersections, the intersection points of the ** tubes must be wrapped in tin foil to prevent mutual influence.

The power supply should remain inside a weak battery. After installing the weak wire, the twist test should be passed or not.

The high level of the wire box is uniform, and the horizontal spacing is uniform. When the switch panel is covered, there is no gap between the adjacent panels. The connection between the wire box and the conduit must be connected with a locking connection, mainly to secure the conduit to protect the wire, and the insulation effect is exempt from the wire conduit.

The wire box is filled in the wires or protected with a special wire cover, and the contrast is placed in the junction box and is not allowed to be surrounded by the wire box. The wire connectors must be connected to the sinking process, the tin should be adequate, the insulation should be double-layered, the packaging should be uniform and tight, and the head should not be exposed. The wire connector should be in the junction box and the power cord connector is not < 5 turns.

The wires of the pull box should be gradually taped in the circuit transformation to avoid injuries to the wires. ▲

Other Considerations:

1.Before construction, you must confirm that the materials used are qualified.

2.Power and communication lines, TV lines, audio cables, and network lines must not be worn in the same tube.

3.There are waterproof requirements, such as kitchens and bathrooms, and PVC conduits and strong wires may not be employed.

Be sure to determine the specific direction. Be sure to determine whether to go to the roof or the ground, and you must choose the best pipe, you must determine the location of the plug board, have a plan in advance, and the socket and plug board must be left more.

It is forbidden to bury the wire directly into the plastering layer, and the flame retardant casing is used to lay, the line pipe is horizontal and straight, and the wire area in the pipe shall not exceed 40% of the section of the line pipe, and the soft casing can be used instead if the groove depth of the top surface or local load-bearing wall is not enough.
