What happens if the zero wire of the socket is reversed?

There are many if the neutral wire and the live wire are reversed, he will not work normally, and it is impossible to even start, not to mention that the neutral wire and the live wire are reversed, but there is no grounding wire.

Now many electrical appliances are not working, and there are many electrical appliances, anti-electric measures, the socket zero live wire is reversed, which will not affect the normal electricity consumption, because single-phase AC 220V is the voltage between the live wire and the neutral line, no matter how the reverse voltage is not changed, and most household appliances (except for some motors, pure resistance appliances) are supplied after AC to DC inside the electrical appliances.

If it is a two-plug appliance, it will have no effect. If it is a three-plug appliance such as a refrigerator, washing machine, and color TV in our home, it still has an impact. The reverse connection between the fire wire and the zero line in the house will cause the zero line of the wall socket at home to be reversed, and the zero fire connection of the three-plug electrical appliances means that if you use a mountain to block the river instantly, there will be a flood.

Therefore, the zero fire connection will cause a short circuit, just like gunpowder meets an open flame, a spark phenomenon will occur, which will instantly cause the temperature to rise by several hundred degrees Celsius.

It will lead to a disaster, and it will lead to the Ministry of Household Appliances.

Household 220 volt electricity, neutral live wire.

It's okay to connect the front and back, but for the sake of rigor, please follow the wiring indicated by the switch. Although non-standard wiring can be used, it will leave hidden dangers in the later stage. Household switches are connected to the live line, and if the switch is on the neutral line, the appliance may still be electrified, which is a common rule.

With this rule, no matter which electrician comes to make repairs, he no longer needs to distinguish which is the neutral line and which is the live wire. This saves time and ensures safety.

If the live wire is reversed with the neutral wire, it is easy to cause electric shock, and it will also cause some household appliances to fail to work normally.

and other electrical appliances appear to be faint flashing after the lights are turned off; The control switch of some household appliances has no effect, and the household use point is AC.

It's just that there are safety hazards when it comes to repairs.

For example, houses are rented, and there are careless maintenance workers

Generally speaking, there is no danger, but there may be danger if there are electrical appliances at the lower level of the socket, and some electrical appliances are installed on the live wire, as long as the socket is disconnected when the equipment is overhauled, there is no problem.

Generally, there is no harm, but there will be a certain degree of potential safety hazards if the zero line of the socket is reversed, and this non-standard operation will not be conducive to the usual maintenance of the circuit.

Ordinary electrical appliances can be used normally when the socket zero live wire is reversed, but because the live wire is a control line, there is still electricity after the equipment is powered off, which may lead to the burning of the internal parts of the equipment, and in serious cases, it may also cause dangerous accidents such as fire.

If the zero wire on the socket is reversed, it will not be affected, one end is connected to the zero wire, and the other end is connected to the live wire, and the alternating current is not divided into positive and negative. The home is used AC electricity, a zero wire, a live wire, the electrical equipment is useless, but the switch is not good, the switch must be the live wire in, the control line out to connect the light, and then the light is connected to the zero line.

If the live wire and the neutral wire are reversed, the neutral wire will be electrified, and even if there is no switch, an electric shock accident will occur if the electrical appliance is touched.

It will lead to the electrification of the electrical shell, which is extremely dangerous and can easily cause electric shock accidents. As a result, the internal wire contact of the socket is not good, resulting in a short circuit or loose pins, and the temperature of the contact is too high, which is easy to cause electrical fire.

Then you will not be able to use it, and you will not be able to charge it at all if you plug it in, and there may be an electric shock accident.

The live wire and the neutral wire are connected incorrectly, although it will not affect the use of electrical appliances, but there will be problems with safe electricity use.

Because the electrical control switches at home are used to connect the live wire, and if the live wire and the neutral wire of the socket are reversed, the neutral wire will directly control the home appliances.

Even if the switch is disconnected, the inside is still charged at this time, and if the bulb is turned off, it will appear to be slightly bright. If a child uses a metal device directly into the socket hole, it will cause a risk of electric shock.

The control line and the neutral line of the lamp are distinguished:

1. In the home lighting system, the voltage value is 220 volts, and there is a live wire and a neutral wire in the circuit. And the switch needs to be connected to the line of fire, which is also a common sense. The switch controls the live wire, the output of electrical products.

In the case of an outlet, access to a light with on/off control is required.

2. First of all, we can see that there is a red wire, which is generally a live wire. It can be done with an electric pen.

To distinguish and determine, the live wire needs to be connected to the switch, and then the output, and the neutral wire to the bulb. Next, turn off the main switch.

The live wire is connected to the switch, and the other end is connected to the light bulb with the neutral wire.

3. Then find the zero line and pass through the multimeter.

If it can be distinguished, it is not lit or there is no voltage to indicate that it is the neutral line, and then it can be wired correctly.

If the live wire and neutral wire are reversed, the device will be damaged.

If the neutral wire and the live wire are reversed, it is very likely to damage the equipment, and even lead to a fire accident, because the voltage value of the neutral line is 0, and the voltage value of the live wire is 220V, the connection of the two will lead to a strong current through, at this time, a huge amount of heat will be generated, and the metal can be melted in serious cases, and even cause fire accidents such as electric collision.

It can be seen that special attention should be paid to the wiring, and the neutral wire and the live wire must not be reversed. If you don't know the knowledge of electricity connection very well, it is more reliable to ask a professional electrician to deal with it.

How to choose home improvement wires?

1. When we buy home improvement wires, we first check how the outer packaging of the wire is, whether the appearance is intact, and whether there is information such as 3C certification, manufacturer name, trademark and production date on it. If severe damage is found, it is recommended not to purchase such products.

2. Due to the large load power, stable performance and good flexibility of copper core wire, it is more expensive than ordinary aluminum wire, but it is still recommended that you buy copper wire, otherwise the wire will fail in the later stage and it will be more troublesome to repair.

3. When purchasing wires, it is necessary to choose according to the size of the section and the type of core, and also combine the actual situation to determine, the home improvement wire is suitable for single-strand wire, with a long service life and is not easy to oxidize.

4. When purchasing wire brands, try to choose well-known brands, such as Baosheng, Chint, Jinbei, etc., these reputations are very good, so that the product quality is more guaranteed, and the after-sales service is better.

Of course, there is a problem, such a connection does not meet industry specifications, and all manufacturers' electrical plugs are connected according to industry specifications.

There is no problem with the socket zero fire wire being reversed, and it is used as usual, but it is not connected to the left zero and right fire according to the normal requirements. Usually when we unplug the plug, the big female finger will be close to the part, left zero and right fire, so that it is not easy to be electrocuted and reduce the occurrence of accidents.

There is no problem with the socket zero live wire being reversed. Electrical appliances can be used in the same way, because the alternating current is not divided into positive and negative poles, even if it is reversed, there is no problem.

The socket is connected to the reverse wire, which basically has no impact on the use of electrical appliances; However, if an individual electrical appliance has a zero live wire and cannot be connected to the wrong special requirements, it cannot be used. It is suggested that there is a chance or correction according to the norms to ensure safety.

Because our electricity is basically 220 volts AC, there is no problem. If there is a problem, the biggest question is the socket with a switch, because the disconnection is the zero line, and the electrical appliances will always be in a live state, I hope it can help you.

If it's a binomial plug, there's no problem.

Who knows how to insert this plug is the right one, and it is impossible to distinguish it at all.
