How to replace the wires in the wall if they are broken, and how to replace the wires that have been

There is an option to trade in the old for the new.

The current wire is generally a live wire process, if there is a problem with the line, directly with the help of the old wire can be extracted and replaced.

In addition, you can also choose to take the bright line, which is a more traditional practice, although it is not very beautiful, but the cost is less, it is more practical, and it is very convenient to replace.

The wires in the wall are broken, how to replace them? The old electrician teaches you the solution by hand, practical electrician technology!

How to replace wires that have been buried in the wall:

1. Replace with a land line.

Find the ground wire in the circuit from the distribution box, remove it from the ground row, replace the original faulty wire, and connect it to the lower port of the circuit breaker. Connect the original faulty wire to the ground row. (The fault wire is the neutral wire or the live wire, which one is specific, you can switch it with the ground wire one by one, and observe whether the circuit breaker continues to trip.)

After changing the cable, it should be noted that the positions of all sockets, ground wires and fault wires under the circuit should be replaced.

2. Threading steel wire.

It is suitable for short distances or pre-embedded threading wires during decoration.

Faulty old wires, if you can, try to pull them out of the conduit. If you really can't pull it out, you can also leave it in the threading tube.

If there is no embedded threading wire during decoration, you can try it with threading wire during maintenance. It is easier to operate when the wire is threaded into the pipe than when the wire goes directly into it. If the distance is short and the angle is small, this method is still feasible.

After threading the wire, a new thread can be pulled in.

3. Deadlift! If threading wire is not used, use the old wire as if it were threading wire – pull the old wire out and introduce the new wire at the same time. Deadlifting is also skillful, pull outward a few times, poke in, in order to adapt the wire to the angle of the threading pipe.

In order to facilitate deadlift changeover, we often avoid a 90° angle when decorating. If a 90° angle cannot be avoided, a threading spring should be installed in the corner.

4. Smash open the wall to re-lay the pipe and thread.

If the old line can't be pulled out, and you don't want to take the open line, you can only smash the wall and rewire. However, if there is no pipeline diagram, it is recommended that it is best not to smash it and re-wire, which is extremely destructive. It is also the last resort and is generally not recommended.

5. Take the bright line.

If you can't change the line, you can only take the bright line. Anytime, the wire is the first choice, no matter how unbearable the conduit is. Of course, many times the sky does not fulfill people's wishes, so in order to be able to use electricity normally, we can only choose to take the bright line.

For open wires, sheathed wires should be selected, and the number of cores should be the same as the number of wires to be replaced. After the wiring is completed, the wire should be fixed to the wall with a line card or trunking.

If there is a problem with the line, you can directly use the old wire to extract and replace the new. However, it should be noted that the horizontal and vertical paving method, it is best to give up this practice, and there are too many curves and curves that are basically not pumped. The point-to-point wire burial method is much more economical and reduces a lot of unnecessary arc bending.

The only way to do this is to break the wall open and renovate it with a new one.

I pull it out and replace it. The wires are usually installed in the pipe inside the wall and can be pulled out.

The repair method for the broken dark line inside the wall is as follows:Material preparation: electric pen or multimeter, new wires, etc.

1. Find the damaged circuit:

If the electrical wiring installed in the home is broken, you can check which section of the circuit is faulty with a tool such as an electric pen or a Banzai meter. When looking for faulty circuits, you can view the circuit construction drawings at home, which is more convenient to determine which circuit is faulty.

2. Replace the damaged wires

You can ask a professional electrician to replace the broken wires. When replacing electrical wiring, turn off the electrical switch in your home. Then remove the switches, sockets or lamps connected to the broken circuit, and you can see the wire and wire outlets.

Then wrap the damaged wire around the pliers and pull it out of the wire. Thread the new wire into the conduit by threading the wire.

3. Assembled completely: the town is absolutely sold.

Finally, install the switch socket or lamp connected to the macro trace connected to the circuit.

If the line is aging, you can unplug the old line and replace it with a new line. This requires that hydropower construction must be carried out in accordance with national standards, and all lines are "live lines". The construction process is to pre-embed the wire pipe first, and then carry out the threading operation.

However, the current status quo of home decoration, most of which are not in accordance with the norms of construction, is a "dead line". The wire is threaded first and then embedded in the conduit, and the wire cannot be pulled in the conduit and cannot be changed. Therefore, after such a line is aged, it is either knocked down and knocked out and redone, or it is reconstructed with an open line.

We should pay attention to the wiring method of the wires. The laying of the wires was concealed and now looks beautiful. But after decades of living, the wires will deteriorate and will be relatively troublesome to replace.

Let's take a look. Nowadays, when the new house is renovated, the wires are laid in the wall, so that the interior looks neater. However, it is necessary to pay attention to the wiring of the wire, and replace it in time in case it is aging in the future.

All the wires in the house are stuck in the walls. How can we change them when they get old in the future?

Most car owners ignore this problem. What should I do if the line is aging? Of course, it's a line change.

So how do you change the line? This requires us to make this preparation when decorating, that is, to wear pipes. All hidden wires must be crossed.

The pipe is not only to facilitate the replacement of the wire in the future, but also to leave the wire in the pipe, so that the nearby ground will not be charged once there is a leakage; The second is to prevent the wires from being sealed directly in the wall, allowing the wires to dissipate heat.

Now let's move on to the problem of changing threads – threading the thread through the threading tube, pulling it out from one end, tying a new thread to the other end, and then changing the thread with a new thread like threading a needle. Do you think it's that easy to change the line? Haha, naïve!

The wires on the walls have aged for years. At this point, the wires will become very hard! There is no line that cannot be pulled out horizontally or vertically, and there must be a certain angle.

The angle is large, and it is slightly easier to pull up. What do you want a right-angled wire to do? What to do with wire joints wrapped in a thick layer of electrical tape?

You can use the steel wire for traction, pull out the wire of the circuit, and then use the thin steel wire as a wire to fill the wall with new wire, which will not damage the wall and can replace the wire in time.

After the aging of the line, the wall needs to be thrown away, the aging wire is replaced, and then the wall is re-grinded, flattened and paved again, so in the process of house decoration, we must choose a better quality of His Royal Highness, and to do a good job of the corresponding pipe reservation.

Nowadays, people hide the wires when decorating the house, so that if the line is aging, the wall must be picked up to get out of the line.

You can use the wire replacement method to remove the two ends of the aging wire, connect the steel wire at one end and drag the other end outward, pull the old wire out, and then replace the new wire with it.

Generally, it will not age, and it is not easy, there are complete wires in the aging wall, and it also plays a certain protective role, the bearing capacity of the wire is very strong, and it will not age under normal circumstances, if it is aging, it may be necessary to chisel the wall.

I think that if the original line is aged, you can pull out the wire of the dark pipe pipe and re-thread it, and there is a professional threading tool to replace it, which will not affect the subsequent use.

At present, almost all home electrical decoration uses the method of concealing wires. The concealed wire is invisible, and the protective sleeve is laid in the wall pre-opened trunking. Due to the concealed application, the household dark wire is not allowed to have intermediate joints, and the wall must be a complete wire.

There are no trunkings at home, let alone wires. It's neat, nice, and comfortable. Enclosures and wiring are not visible in a concealed burial.

When the household power cord fails, it is not convenient for later maintenance. The cost of concealed cable laying is much higher than that of open cable laying.

The line is aging, and it is troublesome to replace the cable. The wires on the walls are aged. At this point, the wires will become very hard!

Neither horizontal nor vertical pulling can pull out any pipeline. It must have a certain angle. We need to prepare when decorating, that is, stringing.

All concealed wires should be threaded. Not only does it make it easier to replace the wires in the future, but it also allows the wires to be left in the pipes so that in the event of a leak, the nearby earth will not be electrified; In addition, it prevents the wires from being enclosed directly in the wall, allowing the wires to dissipate heat. This wire passes through the conduit.

Once unplugged from one end, tie the new wire at the other end and replace the new wire like a needle. Add a junction box. A cable box must be added to the threading pipe of 15 meters or more than 2 right-angle elbows.

The junction box is actually a cross box. There are no connectors in this tape. It is set up to facilitate the removal of aged wires from the conduit.

A junction box is added, and all wire splices are made in the junction box. If there is no need for any switch sockets here, a junction box should be reserved here. There are only connectors in the connector box, so the connector can be removed from the connector box and the wires can be pulled directly when replacing them in the future.

The buried box can be covered with a panel at a later stage, which is not allowed to be sealed on the wall, which is almost the same as connecting the wire directly on the wall. In the process of laying wires, more buried boxes should be reserved in advance, especially at the corners of the wires or when the wires are laid too long, which can not only facilitate future maintenance, but also try to open the buried boxes and pull out the wires when the wires are aging. It is useless not to blindly pursue "horizontal and vertical" in the process of wiring.

Moreover, it is sealed against the wall so that no one can see it. Try to keep a certain arc at the corner of the wire, and add a cassette near the radian.

Personally, I think that you can open each similar embedded box, open or cut the wire joints, and pull it out of one of the junction boxes to see if it can be twitched, destroy the reloading wiring, and smash the wall to solve it.

If it is old, you can only tear down the walls, so this is also a huge disadvantage. Many people like to use storage boxes to hide their wires.

Now there are professional instruments, through which the new line can be directly sent to the wall, which is very convenient to use.
