The home improvement line is short from the main line to the distribution box, how to deal with the

First of all, they can be connected by soldering, which is actually a very critical step when wiringIf you just seem to connect the two together, but they are not really connected together, then it is easy to have problems in the subsequent use process.

Therefore, the correct way is to first fully transfer the wire diameter of the wiring, and then connect them tightly together by welding, and finally use insulating tape when they are tightly wound to prevent leakage, fresh oxidation and so on. In fact, it can be well solved by welding in this way, and the situation that the intermediate joint is insufficient.

In fact, such a way is relatively simple to deal with, as long as you have sufficient tools at homeThen you can complete such a way, in fact, you don't need professional decoration personnel to help you solve such a problem. So it's a way you can consider implementing it in your daily life.

In addition, you can also install a crossing in the middle and in fact, such a way is also a more common way, because welding wires itself is not particularly safe, so if you want a safer method, then install a filter box in the middle. Because in the process of transitioning the wiring, you can install this pass box in this one position, and then put the overwiring in it. So such an approach is actually relatively more stable and safer.

If the total incoming line to the distribution box is short, you can remove the connector and connect the point line.

If it's short, it's directly on the street, and these can be operated by a professional electrician.

If the home improvement line is short, add an intermediate connector and slowly connect it.

If there is a problem with the line, it is safer to find an electrician to repair it.

This problem is more serious, so it's better for you to find a professional to do it, it's safer.

This is a professional question, and I don't know much about it, so I can ask a professional person.

I really don't know about this, you can ask the owner of the place where you bought the electric box.

There can be joints, but it is best not to connect, if the joints are not connected, long-term over-carrying will cause heating or oxidation, resulting in poor contact and affecting the quality of electricity. Or ask an electrician to help you.

Yes, let someone from the power bureau get it or ask someone to get it yourself.

According to the national standard "Code for Construction of Residential Decoration Engineering GB50327-2001", Article 1 stipulates that when laying dark circuits, the wire joints that penetrate the piping should be located in the junction box, the joint lap should be firm, and the insulating tape should be tightly and evenly wrapped.

Special attention should be paid to the fact that the wires in the conduit are not allowed to have joints and are not allowed to be connected through tees.

Wrap it in electrical tape to prevent leakage.

Wire connection, connection electrician knows, the main thing is insulation. The wire diameter is thick, and it needs to be crimped directly with hydraulic pliers.

If the line is short, the following method is used.

First, wire according to the direct connection method of the wire: more than 2 twists in the middle, and more than 5 turns on both sides.

Then do the anti-oxidation and loosening treatment of the tin.

Then insulate with 3M adhesive tape.

Finally, wrap it tightly with heat shrinkable tubing to prevent moisture.

In general, the above treatment methods can be used normally. However, according to the requirements of dark wire laying, the junction box should be placed at the joint position for maintenance.

It's best to go again, and it's okay if you wire it according to the specification. It is better to use a crystal head for the network cable.

The tube can't be connected, so you can only re-route.

Repairs are OK, but they must be wired according to the specifications. Formal installation is not allowed, and the line must be changed.

The length of the cable from the middle end to the end of the high-voltage cable shall not be less than 25 meters.

The so-called wire connection means that when decorating the circuit, the wire needs to be connected with the wire, and this link is called the wire connection.

At present, there are three mainstream ways to connect wires. The first type is ordinary wire winding. This is a method that most renovation companies like to use, which is to simply wrap the copper core of the wire together, and then wrap it with an insulating cloth on the outside.

In the second method, the connection is made using a dedicated wire terminal.

The third method is to wind the wire and brush the tin.

These three methods have their own advantages and disadvantages, the first is that the construction is particularly convenient, which can save labor to a large extent. The second is that you can save a lot of materials, and the price is relatively cheap.

However, the connection of the first method is not very reliable, and it may loosen at any time. The second is that it will loosen after a long time. Compared with the first method, the third method has one more process, so it is more troublesome, and the labor cost will increase, and it will also increase the cost by using a large amount of tin.

We all know that wire joints are very important, but if the wire joints are not handled well, what problems will exist?

First, there is a possibility that the wires will ignite. We often encounter this ourselves, sometimes the socket is inexplicably burned in the process of use, this is because the position of the switch interface at home is also burned.

Second, there are frequent power outages in the home. Some friends have finished renovating and moved in, and found that the home would trip every once in a while. It's not summer, and there's not a lot of electricity, but tripping happens, and in many cases it's caused by the wires not being connected.

When installing power connectors in your home, be sure to use connected connectors to prevent leakage.

If the connector is not connected well, the wires can easily become tangled, which can be dangerous.

Poor handling of joints may easily cause wire ignition and short-circuit power outages.

Wire joints can come according to their preferences, and if the joints are not handled well, they will leak.

The simplest is to use an insulating cloth to wrap the dropped wire, which is relatively low cost and very convenient.

It is possible to use the method of winding ordinary wires, but it is likely to cause ignition.

Most companies will do it directly, plugging the wires together and taping them together, which is also the most primitive method.

We all know that the first step in home decoration is to change water and electricity, which shows the importance of changing water and electricitySo, what is the best connection method for the wire joints in the home? Let's take a look!

1. Conventional winding wiring method

Use two wires to cross the copper wires with each other to wrap them, remember to leave one end to buckle them after winding. In this way, it is possible to ensure that the joints of the wires will not be ignited, short-circuited or in poor contact.

2. Fireproof adhesive tape method

This method is rarely used and is generally used for spotlights in suspended ceilings. It should be noted that the main line cannot be broken, and the secondary wire is wound around the main line for 6-8 times. After that, the outside is wrapped with fireproof tape, which can effectively prevent the outer edge of the wire from being scorched and prevent a short circuit at the wiring.

If the wire joint is not wrapped with insulating tape, the wire will be exposed, which is easy to cause leakage and even electric shock accidents, so it must be wrapped with insulating tape to prevent leakage.

3. Crimping cap connection method

Crimping is a small tool specially used for wire connection, which is very practical and safe. This method is the most standardized and simplest, and it is necessary to have matching crimping caps and pliers when wiring, in which it is very important to choose the matching crimping cap according to the square number of wires connected. When wiring, use the crimping pliers to press the wire, put the special pliers for the crimping wire, put it on the crimping line, and press it hard.

Here I want to tell you one point, generally use the sleeve of wire, and do not use insulating tape.

Problems that will occur if the connection is not good:Household wire and wire joints, the most taboo wire of the joint is not connected to the contact resistance, once there is a contact resistance, this node will produce ignition heat, hot, excessive load and even burn the node and so on.

If the wire joints installed in the house are connected, we generally use the cross winding method, and the hemp rope cross winding method. If the joint is not handled well, it is easy to have the problem of electric contact or poor contact in the later stage. Generally, the connections of large and small electrical joints in the home are handled by people who know more about electricity in the home, because if you hire a worker, it is troublesome and a waste of money, so if you want to connect some wires at home, you can go into battle by yourself, but the terminal is also a technical job, not that the two strands of wire can be screwed together, but it is necessary to go through scientific wiring methods to make the entire electrical appliances for a long time, as well as the firmness and durability of the joints. Today, I will tell you about the two methods and some problems that will be caused by poor connectors.

We can generally use the criss-cross winding method for the thread end in the homeIt is to put the two strands of thread together first, and then the tails of the two threads are screwed together with each other and wound with each other, so that the thread head is firm and strong, and the use time is particularly long, and it is not easy to encounter electricity and leakage. There is also a method, that is, hemp rope cross winding painting, this method is generally suitable for the kind that is relatively small, directly twist the two strands of thread into a strand of hemp rope, and then screw them together again, so that the twisted thread head is wrapped with adhesive tape, and the use time is also very long.

If the wire head is not handled well, it may be used for a long time, and the phenomenon of electric collision or leakage may occurIt will endanger the life and health of our family, so we must take this matter seriously.
