What happens if the neutral line is reversed to the live wire

If the live wire and the neutral line are reversed, will the leakage of the warranty trip? The old electrician teaches you step by step, practical electrician technology!

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.

If the live wire is reversed to the neutral wire, it is difficult to find the abnormality in the initial daily use, but it is easy to cause electric shock, which will also cause some household appliances to fail to work normally.

The switch used to control the live wire has actually become a switch to control the neutral line, which will cause the fluorescent lamp and other electrical appliances to appear faint flashing after the light is turned off. The control switch of some household appliances is used to control the live wire, if it is reversed, it will cause the control switch of the household appliance to control the zero line. That is, when the switch of the appliance is disconnected, the inside of the appliance is electrified.

Therefore, the live wire and the neutral line cannot be reversed.

Precautions for power connection:

1. To prevent electric shock and short circuit.

2. Pay attention to the switch to control the live wire.

3. It is best not to connect the fuse on the zero line.

4. The center of the lamp holder is connected to the fire wire.

5. Do not mix the grounding wire and the neutral wire.

6. Cut off the fire wire with electrical appliances, so that the electrical appliances will not be electrocuted, and if the zero line is broken, the people will be electrocuted if they touch the electrical appliances.

The neutral line is reversed from the live wire, which will have potential safety hazards. Because some equipment uses a two-wire plug, if the power supply of the device is live

The reverse connection of the zero line or the wrong position in use will inevitably cause a short circuit in the live wire and the zero line, burn out the equipment, and cause irreparable losses.

In order to make the alternating current have a very convenient power conversion function, usually the power transmission is in the form of three phases and four wires, and the three heads of the three-phase electricity are called.

The three tails of phase wire, three-phase electricity are connected together and are called neutral wires, which are also called"Zero line"。The reason why the zero line is called is that there is no neutral line at the moment of three-phase equilibrium.

The current passes, and then it is directly or indirectly connected to the earth, and the voltage with the earth is close to zero.

The earth is a good conductor, and the ground wire is short-circuited to the earth through a deeply buried electrode. The transmission of mains power is in a three-phase manner, and there is one one.

Neutral wire, the current of the neutral wire is zero when the three-phase balance is commonly called"Songbi zero line"Another feature of the neutral wire is the total distribution input with the ground wire in the system.

Short-circuited, the voltage difference is close to zero. The three phases of three-phase electricity have a voltage of 220 and the neutral line, which will produce an electric shock to people, commonly known as it"Fireline"。

In electrical engineering, the alternating voltage connected to the mains line is 220 volts (abbreviated as volts, the symbol is V), and one of the lines is connected to the earth, which is called.

This is the "zero line" and the other line is called the live line. In electrical engineering, it is often referred to as the neutral line of fire or the one-zero-one fire.

The circuit switch for entering the home is generally to cut off the live wire and install a leakage protector to prevent personal electric shock accidents.

Under normal circumstances, the ground wire will not leak, and the common ones are: two-hole, three-hole socket. In general: in two holes, the left hole is connected.

is the zero line, and the right hole is connected to the live line. In the three-hole socket, the upper hole is connected to the ground wire, the left hole is the neutral wire, and the right hole is the live wire.

The live wire is the power line that transmits electricity in the circuit.

The neutral line, mainly used in the working circuit, leads out the trunk line after grounding from the neutral point of the transformer. (You can use a tester to determine which one is not.)

Fireline

According to Qeeka Home experts, the main difference between the neutral wire, the live wire and the ground wire is that the voltage is different, so when wiring, the neutral wire must be connected with the neutral wire, and the live wire must be connected with the live wire, so as to ensure the safe operation of the circuit. So, what happens if the neutral wire and the live wire are reversed? How to choose home improvement wires?

Let's take a brief look at it below.

1. What happens if the neutral line and the live wire are reversed.

The reverse connection between the neutral wire and the live wire may damage the equipment and even cause a fire, because the voltage value of the neutral wire is 0, while the voltage value of the live wire is 220 volts, and the connection of two points will produce a very large current, generate huge heat, and can even melt the metal, so the neutral wire and the live wire must not be reversed.

Second, how to choose home improvement wires.

1. When purchasing home improvement wires, you must first check whether the packaging of the wire is in good condition, if you find that there is serious damage, it is recommended not to buy, in addition, you also need to check whether there is 3C certification on the outer packaging, manufacturer name, trademark and production date and other information.

2. Because the power of the copper core wire is relatively large, the performance is more stable, the flexibility is good, and the service life will be longer, so the corresponding ** will be much more expensive than ordinary aluminum wire, but when purchasing, it is still recommended to buy copper wire, after all, the wire is faulty, and it is very troublesome to maintain.

3. The wire can be divided according to the size of the cross-section, or according to the type of wire core, and must be decided in combination with the actual situation when purchasing, the general home improvement wire is more suitable for single-strand wire, with a long service life and not easy to oxidize.

4. There are many brands of wires, and when purchasing, we should try to choose well-known big brands, such as Baosheng, Zhengtai, Jinbei, etc., which have a good reputation, and the brand was created relatively early, the product quality is guaranteed, and there is perfect after-sales service.

Summary: The above about what will happen if the neutral wire and the live wire are reversed, and how to choose the home improvement wire is introduced here, I hope it will help you. If you want to know more about related information, please pay attention to Qeeka Home.
