Why are all three wires of the socket electrified?

The reason why there is electricity on all three wires of the socket is that there is power in series. The possible reason is: there is leakage of other electrical appliances, the live wire has a shell, and it happens that the zero wire is open again, and the ground wire is not connected to the protective ground, so this rare phenomenon occurs The three wires of the socket are electrified.

Here are three reasons why:

1) The ground resistance of the ground wire is too large.

2) Equipment leakage.

3) Induction (test voltage, should be inductive low).

Blue is the neutral line, red is the fire line, and yellow is the ground line. According to the color code: blue is the zero line, yellow is the green line or black is the ground line. Red and yellow line of fire.

The reason why all three wires of the socket have electricity is that your live wire and neutral wire have been hit. That is to say, if your live wire and neutral wire are next to each other, it is a short circuit, usually something is burned out, and the wire is put together, or the plug on the socket is two together.

First of all, we have to understand what the red, yellow and blue lines represent, usually, red represents the fire line, yellow represents the ground line, and blue represents the zero line. If you still can't remember, we can also judge by the letters, where n represents the zero line, e represents the ground wire, and l represents the fire line.

What should I do if the live wire is not red during the installation process, but is replaced by a wire of other colors? We can use electric pens.

Let's test which line is the live wire and the neutral line, during the test, if the pen light is on, it means that the line tested at this time is the live wire. If you don't have an electric pen nearby, you can only go to the electric switch.

Let's take a look at which one is the live line and the zero line.

After judging the live wire and the neutral wire, we can connect the socket with the wire, in fact, the live wire is connected to the L interface, the neutral wire is connected to the M interface, and the ground wire is connected to the E interface, so that the wire is connected.

Finally close the socket cover and use a screwdriver.

Tighten it, then use an electric pen to test if this outlet is usable, or simply use a small night light to test if this outlet is powered on.

Because there are also some sockets with switches, if it happens that the socket you use is with a switch, then when connecting the live wire, you can directly connect the live wire to the interface of the switch.

Then connect the ground wire to the E connector and the neutral wire to the N connector, then close the socket cover and tighten it with a screwdriver. Finally, use an electric pen or night light to test whether this socket is powered on and whether it can be used normally. The plug has two wires and also has three wires, how do I connect the three wires in the plug?

What should I look for in the wires of an outlet? Let's investigate this editorial.

How do I connect the three wires in an outlet? The line on the left is the 0 wire, the line on the right is the live wire, the middle wire is the ground wire, the three wires in the ordinary socket are the red live wire, the blue wire is the 0 wire, and the green wire is the ground wire.

**。When wiring at home, the metal wire and the metal shell need to be grounded protection, and the laying line is controlled within meters, in addition, when laying the wire, the wire can not be directly buried in the cement, and the buried depth of the general wire is more than 10 mm, but if it is hung on the concrete ground, you can use the covering line.

The neutral wire of the transformer can be connected directly to the neutral wire, but the live wire and the circuit make up the circuit, there is no voltage drop loss in the process of closing the circuit, however, the ground resistance of the neutral wire and the neutral wire.

The requirements are higher, that resistance is best within 10 ohms, if it is a voltage of 100 kV, the ground resistance is best within 4 ohms.

Generally, the ground wire of the transformer is connected to the neutral wire and the neutral wire, and then the distribution box is wired separately.

Grounding is also repeated in .

However, the grounding resistance is best controlled within 30 ohms, if the cross-section size of the neutral wire and the live wire are the same, then the grounding wire cannot be used when passing through the same size of current.

Make a zero line.

If the three wires of the socket are electrified, then it is likely that the ground wire and the neutral wire are broken, and it is recommended to find a professional electrician to check it.

The reason why there is electricity in the three wires is that you have a fire wire and a neutral wire and a ground wire, and there is a place to connect them together, or because it takes a long time, your wire is thinner, and then the three of them melt together, and the reason why the J is inserted into the three wires are electrically connected, which means that your live wire and the zero wire, and the ground wire have been mixed between them, and there is a place to connect them together, or because it has been used for a long time, your wire is thinner, and then the three of them are hot and melted together, melted that insulation away, and then the three of them struck the iron, and the three of them were together. If this is the case, it is not easy to find a leakage.

In this case, the ground wire should not be connected.

So the other neutral wires will have voltage.

The ground wire is an induced electricity.

For some sensitive appliances, there is a risk of danger.

Ordinary electrical appliances do not affect the use.

It is possible that the front end neutral line is broken or the maintenance connection is wrong. The household wire is separated from the entrance box, so after the zero line is broken, the zero line behind it communicates with the live wire through electrical appliances, so there is "electricity".

The three wires of the socket are electrified, it may be that there is a possibility of insulation damage in the socket, or it may be the cause of the power supply, it is recommended to find an electrician to check the circuit.

The three wires of the socket are electrified, indicating that there is a short circuit, and only one of the three wires of the socket should be live, one is grounded, and one is the neutral wire.

When the power cord is too long or there is electrical leakage, test with a voltage tester to have a live indicator on the ground wire and the neutral wire adjacent to the live wire. If it is not possible to ensure that the ground wire is well grounded, it is necessary to connect a working leakage protector in front to ensure safety.

There are several possibilities:

One is that the socket is broken;

the second is that the wiring is wrong, and there is a place for UMC;

The third is that if the ground wire is not connected to the neutral line, there will be voltage.

The reason why all three wires of the socket have electricity: It is normal for the live wire to have electricity. The voltage tester found that there was electricity in the neutral line, which was broken and plugged in with an electrical appliance (resistive or inductive). The ground wire shows that there is electricity, indicating that there is leakage.

If the three wires of the general socket are electrified, the reason is a short circuit, that is, it burns out and causes the fire wire to contact the neutral wire and the protective ground wire to form a short circuit.

Generally, the three wires of household sockets are a separate port above is the ground wire, the lower side of the 2 holes, the left is the zero line, the right is the live wire, if the three wires have electricity, either the wrong wire, or there is a short circuit, there are a few induction electricity is too high, caused by poor grounding.

The reason why the three wires of the socket are charged should be that there is leakage, or the three wires are connected together, which will cause them to be electrified.

The reason why the single-phase three-wire sockets are energized is that the working zero line is broken, the zero line has to be protected and the zero wire is broken (or not connected) and the electrical appliance itself is leaking.

This is a circuit loop, and out of the three wires, one is the live wire, one is the neutral wire, and one is the ground wire.

The three wires of the socket have electricity, which means that the socket is short-circuited inside, and the ground wire of the neutral line of the live wire is put together, and the short-circuit point can be repaired by finding the short-circuit point.

In the case of what you said, either there is leakage between the lines, or it is caused by the open circuit of the neutral line or the ground wire, which is more dangerous to use, and you must first find out the cause and solve it.

The reason why the three wires of the socket are electric is that the neutral wire is broken and the ground post is vacant and not connected.

If all three wires have electricity, this is a good indication that your neutral wire has touched one of the wires.

According to your description, the first thing to do is to confirm the concept of "all have electricity", if the voltage is 220V and above, then it is very dangerous. If it is only an induction current, such as testing the electricity with a voltage detector, but it can be used normally, it can only indicate that there is leakage, that is to say, the neutral wire or the grounding wire is poorly insulated, and it can only be used normally after the fault is repaired by professional and technical personnel. Thank you for your understanding and support!

The reason why the three wires of the socket are electric may be leakage, so you must pay attention to safety and do not know how to find a professional electrician.

The reason why the three wires of the socket have electricity are sold Zheng? Kiss! Hello, we are happy to answer for you.

The reason why all three wires of the socket have electricity is that there is electricity due to the disconnection of the wiring of the neutral wire. Under normal circumstances, the zero line will generally not have electricity, and if there is electricity in the zero distribution line, then it is likely that there is a problem with the circuit, or the electrical leakage phenomenon occurs, and at this time, the zero line current will not cause tripping, so the zero line will have electricity.

Use the voltage test meter to test, household electricity is generally three wires, there are live wire, neutral wire and ground wire, the voltmeter test out of the high voltage is the live wire, the voltage value is very low or even no is the zero line, the ground wire generally has no voltage, I hope mine can help you! Do you have any other questions?

Hello, the three wires are three-phase wires, which are safer for high-power electrical appliances.

If you encounter similar problems in the future, you can follow the following ideas to solve them:

1. Finding problems: often living in the world, always in these kinds of contradictions, when some contradictions are projected into consciousness, the individual only finds that he is a problem, and asks to find a way to solve it. This is the stage where the problem is discovered.

From the perspective of the stage of problem solving, this is the first stage and the premise of solving the problem.

2. Analyze the problem: In order to solve the problems found, it is necessary to clarify the nature of the problems, that is, to figure out what contradictions there are, which contradictions, and what is the relationship between them, so as to clarify what results the problems to be solved, the conditions that must be met, the relationships between them and what conditions have been met, so as to find out the important contradictions and key contradictions.

3. Put forward hypotheses: on the basis of analyzing the problem, put forward hypotheses to solve the problem, that is, the solution that can be adopted, including what principles and specific ways and methods to take, but all of these are often not simple and ready-made, and there are various possibilities. However, putting forward hypotheses is the key stage of problem solving, and correct assumptions lead to the smooth solution of the problem, while incorrect and inappropriate assumptions lead to detours or lead the solution of the problem astray.

4. Verify the hypothesis: The hypothesis only proposes n possible solutions, and there is no guarantee that the problem will be solved, so the last step in problem solving is to test the hypothesis. In either case, if the test does not produce the expected result, a new hypothesis must be proposed and tested again until the correct result is obtained, and the problem is not solved.

The brown line is the fire wire, the blue line is the zero line, and the yellow and green color line is the ground wire. Just connect the brown and blue lines. But it's best to connect the three-pin plug so that it's safe.

The two wires are connected to the two pin terminals under the three-pin plug, the lower left corner is connected to the neutral wire, the lower right corner is connected to the live wire, and the upper one is the grounding wire that does not need to be piped. Then reinstall the triple plug and it's connected.

The three-wire plug is a live wire, a neutral wire and a grounding wire, and the function of the three-wire plug is to better protect the safety of the staff using household appliances with metal shells, so as to prevent the staff from leaking electricity and electrocuting during use.

Three-wire plug structure:

Three-pin socket: "left zero right fire on the ground" (the ground wire is generally connected to a metal plate buried in the ground). Three-wire plug:

Appliances with metal casings are basically three-wire plugs, which correspond to three-pin sockets. The function of grounding: the plug in the middle of the three-wire plug is connected to the metal shell of the electrical appliance, and when the three-hole socket is inserted, the metal shell is connected to the earth.

Civil 220V electricity, one live wire, one neutral wire, three wires for safety, plus a ground wire, it is safer to have a grounding wire.

The first method of connection. The live wire is connected to the leftmost hole, the zero wire is connected to the adjacent hole, if there is a ground wire connected to the hole in the middle, if you want to control the lamp, then the switch control wire is connected to the hole on the top of the switch, this is a socket with a switch, the second connection, if you want to use the switch to control the socket, then the live wire is connected to the hole above the switch, and the zero wire is connected to the hole on the right.

The 220V voltage itself is two wires, a live wire and a neutral wire, and the third wire is a grounding protection wire, there is no electrical appliances can operate normally, why add an additional grounding protection wire, is it an extra move, the answer is no, the general small household appliances are plastic shells, even leakage will not hurt people, so the use of two wires can be, and some household appliances shells are iron, due to some reasons the live wire on the terminal is loose and falls off, the shell of the electrical appliances will be electrified, Once a person touches it, it will be electrocuted, resulting in **, with this grounding protection wire, it can lead the current into the ground, so as to play a role in the safety protection of people!

1. How to connect the three wires in the socket.

The socket is usually connected to the neutral wire on the left, while the live wire is connected to the right side, and the ground wire is in the middle. The line in the normal socket, the red wire is the live wire, the blue wire is the neutral wire, and the yellow and green wire is the ground wire, and we can connect it according to the color. So the red wire is connected to the live wire, while the blue wire is connected to the neutral wire and the green wire is connected to the ground wire.

When wiring, they cannot be connected incorrectly, otherwise there will be certain safety accidents.

When wiring in the home, whether it is a metal crust or a metal wire, it must be grounded and protected. And the laid lines must be kept in meters. When laying wires, the wires should not be directly embedded in the cement.

Generally, the depth of wire embedding must be more than 10 mm. If there is a cast-in-place concrete floor, be sure to use a sheathed line.
