How do you change the wires in an old house? How to replace the old house wire with a new one

It's hard to say. If you have a fever, you can only pull a new route from the electrical box.

If it is a dark line (that is, the trunking is into the wall, floor, ceiling, etc., you can't see the trunking, it does not affect the appearance) This type is more troublesome, if you want to continue to use the dark line, you have to cut the place where the line passes, or chisel another line groove. It's all time-consuming work.

It's much easier with topstitching. Just uncover the trunking and pull a more route.

If you are familiar with the bright line, you can do it in 1 hour, and if you have some basic knowledge, you can pull it yourself, look at the local price, give half a day, and the price of a day will be on the line.

If it is a dark line, you have to plane the line and repave, one day, two days, or even longer, it is possible, depending on the path you take, and the work is heavy. It's hard to say the price. Because your line is going through the floor?

Over the wall? Or into smallpox? How long is the trunking from the electrical box to your electric water heater?

These are the ones that determine the length of hours employed. Imagine for yourself how long it will take to chisel these and how long it will take to re-pave them. According to the local price of the approximate estimate, get a psychological price, remember to ask a few more decoration masters what is the minimum price?

If you can't cut it down, you can only admit to slaughter!

It's not very troublesome, and it's best to find the person who originally constructed the stringing. There are down line pipes in the wall, and the old wire is pulled out and replaced with a new one. Find an electrician and study it to find out the salary.

1. If it is a wire in the wall, you can only use the main type of wire traction, pull out the old wire, and then replace it with a new wire.

2. The amount of work is large and cumbersome, which is to disassemble the wall and open the pipeline for replacement.

3. If you don't consider the wires inside the wall, it is also a good way to re-lay the new wires outside the wall and design the new wires into a pattern.

The old house is twenty years old, and the wires have to be replaced.

Hydropower projects are related to whether the living is convenient and comfortable, and also related to potential safety hazards.

Some old house wires after decades or even longer, water pipes and wires are aging, if you continue to use then it is not the best to say that there will be problems, and then it will be rebuilt when you move in later, which will be more costly.

Therefore, it is best to replace these aging wires and water pipes for the decoration of old houses. In fact, it is not just the old house, if the new house is not very good if the wire reserved by the developer is not very good, then it is also recommended to replace it, but it depends on the specific situation.

The decoration of the old house is not only the water pipes and wires to be replaced, including the old electrical box is also best replaced, because there will be some faults in the empty opening time of these electric boxes for a long time, or some have no leakage protection at all, and there is a state of failure if there is a false alarm, for the safety of the home electrical appliances, because the failure of the false alarm will also cause a short circuit of the electrical appliances, and the serious electrical appliances will be burned out, so it is best to replace the electric boxes empty.

Precautions. Pay attention to the capacity when replacing the wires in the old house, the wires used in the old house are basically the same, and the use of some large appliances or multiple electrical appliances will cause tripping, such as air conditioning and refrigerators, which is the wire capacity is small.

Therefore, it should be noted during the construction and replacement that ordinary lighting lines can be used, but some electrical appliances with large power consumption such as air conditioners and refrigerators are best replaced by four squares, so that they can be used at the same time without causing tripping.

In particular, some electrical appliances in the kitchen, what whole ovens, induction cookers, boilers, and some new novel household appliances now consume a lot of electricity, so it is best to replace these wires and arrange them reasonably, so that they will not trip when using multiple electrical appliances.

The old house is twenty years old, and the wires have to be replaced. Because of the long term, the wire will age, easy to cause short circuit, insulation performance decline, especially in wet weather, moisture will soak into the metal conductor, short circuit, so in order to ensure safety, try to replace the wire with a new one.

If there is a plan to decorate, the wires are best replaced together, and the lines will have a certain degree of aging in 20 years, and there may be certain risks in daily electricity. However, it still depends on the specific situation, if the decoration is better with materials, it is not necessary to change it if there is no problem after checking, it is best to combine the situation of the house.

Precautions for decorating pulling wires

1. Scientifically select the thickness of the wire.

If the electrical power is large, you can choose a thicker wire, and the wire that is too thin is easy to heat.

It was even punctured, causing a fire.

2. Choose a reasonable installation form.

Depending on the situation, choose the light and dark installation method, which can be along the wall or ceiling.

The surface is laid, but the spacing between the wires should be appropriate, and it is forbidden to squeeze or fold, and if it is concealed, the wires are buried in the wall, which is generally operated by professionals.

3. The correct way to connect.

When laying wires, try not to produce too many joints, if there are too many joints, it will affect the appearance, and will also produce a large resistance, which is easy to cause the wire to heat and burn, if you want to connect, you must wrap it with special tape.

4. Use the ground wire correctly.

When decorating the cable, it is necessary to pay attention to some high-power electrical appliances, such as water heaters, air conditioners, etc., which must choose three-phase plugs and connect to the ground wire. The lighting wiring must not be connected one line at a time.

Nowadays, when every family is decorating, they will pay special attention to the choice of wires, after all, it involves the quality and safety of electricity in the future life. Some old houses have been used for a long time, and it is a big expense to renovate the wires. Let's take you to understand, the old house has been 20 years old, the wires have to be replaced, and the household wires are 6 square or 4 squares?

The old house for 20 years the wire needs to be replaced, because the line base is aging, and now the electricity demand is not the same, the kitchen 4 square copper wire, the room square copper wire, there is no need to change, it is best to redesign the construction, one is because the wire will be aged for a long time, the second is that the original line design is not as large as the current load, the wire diameter is small, for the sake of safety it is recommended to replace all.

Household wires 6 square or 4 square is better.

1. The general lighting socket and lighting wire are enough to use square wires, and the lamps and lanterns at home are connected in series, generally not exceeding 500W, and the wattage of large crystal chandeliers will not exceed 1000W.

2. High-power electrical appliances at home, such as air conditioners and water heater sockets, can use 4 square wires. If you use 6 square wires, although it will indeed be safer, it will also increase the difficulty of construction, and the area occupied by the socket bottom box will also become larger, which is not conducive to home decoration.

3. There are many kitchen appliances, such as range hoods, rice cookers, microwave ovens, soybean milk machines, boiling kettles, etc. You can use a 4 square line to go to the top, and then arrange the socket underneath, use the square wire to connect the fire, all the sockets are connected from the 4 square wire macro or separately. However, it should be noted here that the 10A socket can only be connected to the square wire, and only the 16A socket can be connected to the 4 square wire.

The old house has been in the house for 20 years, and the wires of the household are 6 square or 4 square meters, and the whole content is introduced here. Wires, the larger the number of squares, the larger the volume, the more expensive, and the more complicated it is to install.

To replace the aging wires in an old house, you can follow these steps:

1.Safety checks: Before replacing the wires, make sure that you are safe first. Make sure the power is turned off, close the circuit breaker, or unplug the fuse. Use a voltage tester to confirm that no current is flowing through the wire.

2.Plan the wiring: Make a plan for the wiring of the wires as needed. Determine the number and length of wires required for each room or area.

3.Prepare materials and tools: Purchase the wires, accessories, and tools you need, such as repair connectors, cord clamps, insulating tape, wire strippers, screwdrivers, etc.

4.Remove old wires: Carefully remove old wires and trace the lines to determine the path of the wires. Mark the location and purpose of each wire so that it can be corresponded to when installing a new wire.

5.Install new wires: Route the wires according to the plan. Use wire strippers to strip the insulation from the ends of the wires, then use cord clips to connect the wires to the socket or light fixture.

6.Connecting Circuits and Protective Devices: Connecting wires to electrical outlets, switches, and lighting fixtures according to wire wiring calculations. Make sure all connections are strong and reliable.

7.Test the wires: Before turning the power back on, use a voltage tester to test that the wires of each outlet and switch are connected correctly. Make sure all wires are properly grounded and insulated.

8.Complete the installation: Repair the walls and ceiling, and install equipment such as outlets and switches back in place.

It should be noted that the replacement of wires involves electrical work, if you do not have the relevant knowledge and experience, it is recommended that the person who instructed the wire ask a professional electrician to complete it to ensure that the work is safe and reliable.

Replacing wires requires some electrical knowledge and skills, and if you're not sure if you'll be able to do the job, it's best to hire a professional to do it. Here are some rough steps:

1.Turn off the power: Before replacing the wires, first make sure that all the power is turned off. This can be achieved by opening the distribution box or turning off the light bulbs in the chain.

2.Remove the old wires: Remove the old wires from the socket or light fixture. Be careful when disassembling to avoid damaging the wires or surrounding components.

3.Buy a new wire: Buy a new wire that matches the voltage and power of your home. It is best to buy wires with good brand reputation segments and reliable quality.

4.Connect the new power grandson wire: Connect one end of the new wire to the plug of the socket or light fixture, and the other end to the power junction box. When connecting, follow the marking and instructions of the wire.

5.Install the wires: Install the new wires on the socket or light fixture and follow the instructions in the instructions.

6.Turn on the power: After completing the wire replacement, turn on all the power and check whether all electrical appliances are working properly to ensure that the wire replacement is successful.

Please note that when performing wire replacements, it is important to follow electrical safety regulations to ensure personal safety and the safety of the surrounding environment. If you're not sure if you'll be able to do this task, it's best to ask a professional to do it.

<> first need to understand the household appliances of the old house, calculate the load of the line, so as to choose the wire reasonably. Then remove all the openings in the house, pull out all the lines, and then use the thin steel wire as a wire, pull the new line through and pull out the old line, and then wear the dark line, and finally replace the line without the pipe with open paving. What needs to be paid attention to when changing wires in old houses is to make a good layout, and it is best to have relevant circuit drawings, especially in the kitchen and other places where there is a lot of electricity.
