What happens if the ground wire and neutral wire are reversed when connecting the switch socket?

The neutral line is also called the neutral line, and the power supply station supplies power to the user through the live line, and then returns to the nearest substation from the neutral line to access the earth to form a complete circuit. The ground wire is connected to the metal shell of electrical equipment and then introduced to the earth, mainly to prevent the occurrence of leakage of the metal shell charged so that the human body is exposed to electric shock damage, once the metal shell is electrified, most of the current can be introduced into the ground through the ground wire, so as to reduce our electric shock damage. The ground wire is grounded under the user's residence.

When I connect the switch socketIf the ground wire and neutral wire are reversed, the circuit will fail. The ground wire and the neutral wire are reversed, which will cause the circuit to be short-circuited or the neutral wire to be burned. If the zero wire is burned, the shell of the appliance is equivalent to the fire wire, and once the human body comes into contact, it will be subjected to electric shock, which poses a threat to personal safety.

SecondlyLeakage protection switchVery important. The reverse connection between the wire and the neutral wire will lead to the occurrence of leakage, at this time, the leakage protection switch plays a vital role, when the socket leakage, the leakage protection switch will automatically cut off the switch.

Plays a protective role. Finally, circuit installation should be done by a professional. There is a saying that there is a specialization in the art industry, and if you don't understand something, don't try it easily, and it's quite troublesome to repair the line.

First, there will be a short circuit when the ground wire of the socket and the neutral wire are reversed. The line used on the socket cannot be connected in reverse, and the live wire and the neutral wire must be installed in the position where it should be, and if it is reversed, there will inevitably be a short circuit in the circuit. <>

Second, the leakage protection switch is a very important device. Leakage protection switch can be said to be a very important part of home life, if you accidentally make a mistake in this link, there may be a big accident, so when installing leakage protection devices at home, you must choose a more reliable brand. <>

Third, the line must be installed according to the requirements. This kind of thing is not a joke, when installing the line, you must invite professionals to install, so as not to have more follow-up troubles, and it costs a lot of money to repair, professional things have to be done by professional people, and it is better to ask a good master than to call someone to repair the line.

When connecting the switch socket, if the ground wire and neutral wire are reversed, it will cause a short circuit or trip. As soon as the load is working, the leakage switch will trip! The leakage switch is often not a single independent, but is linked with the air switch.

If a single air switch trips, it is a short circuit or overload of the load.

Reverse connection will make the electrical shell live will cause a short circuit, the result of the short circuit is one trip, and the other is to burn one of the phase wires or neutral wires. If the neutral wire is burned first, then the shell of the appliance is equivalent to the phase wire (live wire).

The electrical shell will be energized due to the fault, which will cause a short circuit, and the result of the short circuit is to trip and burn off one of the phase wires or neutral wires. If the zero wire is burned first, then the shell of the electrical appliance is equivalent to the phase wire (live wire), and people will be shocked if they come into contact with the shell of the electrical appliance! At this time, even if the leakage protection switch is installed in the home, the leakage switch will not jump before the person touches the electrical shell!!

This means that the switch will only trip after a person has been shocked. It is very dangerous to encounter the failure of the leakage switch.

The ground wire of the zero line of the socket is reversed, not to mention the safety issue, but also the question of whether it can work normally.

1. If there is no leakage protection switch at the front end of the socket in the distribution box, then the electrical appliances can work normally.

2. If there is a leakage protection switch at the front end of the socket in the distribution box, then there are two situations:

1) If the power of the electrical appliance is small, such as charging a mobile phone, such as a table lamp with low power, due to the small current, the current "leaking" to the ground does not reach the extent that the leakage protection switch does not trip to the action, then, the electrical appliance works normally.

2) If the power of the electrical appliance is large, such as the impact electric drill, as well as the previous CRT display, etc., in the case of such electrical appliances as soon as they are turned on, the electric drill will start and stop, or the display will be extinguished when it is lit, because the current "leaking" from the ground wire reaches and exceeds the leakage current of the leakage protection switch, so that the leakage protection switch trips and avoids the occurrence of electric shock accidents.

Of course, how much power of the electrical appliances will work normally, and how much power of the electrical appliances will protect the tripping, which depends on the specifications of the leakage protection switch, depending on the sensitivity of the leakage protection switch to the leakage current.

The lead point of the neutral wire is the neutral wire of the transformer. The ground wire is the protective wire that connects the shell of the electrical appliance with the earth, and the neutral wire of the live wire is the return route of the electrical appliance. If the live wire is connected to the ground wire incorrectly, not only the electrical appliance will not work, but the electric energy will run to the earth through the ground wire and be wasted, and the electrical appliance will not work if it is connected to the ground wire.

If the neutral wire and the ground wire are reversed, and the leakage protector is not used, it can be used normally, because the voltage of the live wire and the ground wire is also 220 volts, but if the ground wire is not properly grounded, it will cause the voltage to rise, and it is easy to burn out the electrical appliances.

If the neutral and ground wires are reversed, can the appliance work?

If the neutral wire and the ground wire are reversed, the appliance will not work properly. If there is a leakage protector, it will jump away. If there is no leakage protector, the voltage may drop because the grounding of the ground wire is not necessarily good.

But either way, this is unsafe wiring and must be corrected.

The neutral ground wire is reversed, as long as the incoming switch does not trip, the appliance can work normally. However, the zero wire and the ground wire are reversed, which has potential safety hazards and must be wired according to the specifications.

Under normal circumstances, it will not work, but there is a situation that the ground wire is well grounded, and there is no other electrical work on the zero line, it may work, but the electrical shell may be electrified, which is more dangerous".

If it is a regular power supply equipment, the electrical appliance cannot work, and it is very dangerous for the neutral wire and the ground wire to be reversed, and the risk of electric shock will occur.

In the process of decorating a new house, the installation of the circuit cannot be wrong, otherwise it is very easy to bury potential safety hazards, not to mention the later use, and also bring a serious threat to the safety of the occupants. So what happens if the zero wire and the ground wire of the socket are reversed, and how to judge the reverse connection between the zero wire and the ground wire, do you understand? Now let's take a look.

1. What happens if the zero wire and ground wire of the socket are reversed.

If the zero wire and the ground wire of the socket are reversed, the electrical shell will be electrified, resulting in a short circuit, which will either trip or burn the phase wire or neutral wire. If the zero wire is broken first, it is possible to make the electrical shell equivalent to the live wire, even if the home is equipped with a leakage protection switch, only after the person is shocked, the switch will trip, which is very dangerous.

2. How to judge that the neutral wire and the ground wire are reversed.

1. In the process of inspection, it is necessary to turn off all the electrical appliances at home to avoid the phenomenon of electrical tripping, resulting in damage. After turning off the appliance, have a multimeter and pen ready.

2. Use an electric pen to measure three wires at the switch, if the electric pen is bright, it means that one belongs to the live wire, and the remaining two that are not bright belong to the neutral line and the ground wire.

3. Then, the multimeter comes in handy, adjust the multimeter to the ohm level, put the red pen on the multimeter on the line of fire, and the black pen on one of the other two, and detect them separately.

4. If there is a tripping phenomenon, it means that the one that the black pen is in contact with belongs to the ground wire; There is no tripping, but the value displayed on the multimeter is 0, which means that the black pen is touching the zero line.

5. It should be noted that before the test, the leakage protection needs to be installed on the switch, so that in the process of closing, the leakage protection that pops up will be pressed down.

What happens if the zero wire and the ground wire of the socket are reversed, and how to judge the reverse connection between the zero wire and the ground wire, I will introduce it here, do you understand? The zero wire and ground wire of the socket are reversed, which is very troublesome and needs to be adjusted in time, so as not to bring potential safety hazards to future life and is not conducive to normal living.
