What happens when the neutral wire in the binomial plug is connected to the live wire? 15

If you have a short circuit in this case, it should be that the circuit breaker trips, and the leakage protection will not trip, let alone hurt people. The leakage protector only acts when there is grounding (including electric shock to the human body).

When the switch capacity is small, it will trip, the switch capacity will not trip, it is very dangerous, the current of the short circuit is very large, which will cause burns and electric shock, the household switch is a leakage protector, in the case of leakage, the current of the live wire and the neutral line is unbalanced, resulting in the action of electronic components tripping, not protecting the two wires at the same time electrocution, short circuit.

The distribution box will trip if the distribution box is good and installed correctly.

In this case, it is a short circuit (the neutral line of the live wire is not connected by the electrical equipment), which will not hurt you, but will cause the distribution box to trip or the distribution transformer to trip.

But what I don't understand is that you know that the plug is shorted and you don't change it!!

If the short circuit is on fire, it must be protected by leakage and short circuit.

Short circuit, sparking, automatic power cut-off with section device.

Now the protection device is better, basically a circuit breaker, if the neutral wire and the live wire are short-circuited, the circuit breaker will operate for many years, when there is no circuit breaker before, the fuse will be used, if the neutral wire and the live wire are short-circuited, the fuse will be blown out, both will play a protective role, but the former can be used many times, the latter is disposable, once the fuse is blown out, the first fuse must be replaced.

It depends on the quality of the shell, a good one, fire resistance, heat resistance is a little more harmful to the operator, otherwise it will burn the operator's fingers. Of course, at the same time of short circuit, the circuit breaker in the distribution box will trip, you can choose a better circuit breaker, such as: Delixi's DZ47 series, if you want to be safer, choose Schneider's C65 series, and at the same time with a leakage protector, which will be safer.

When the two-pin socket is installed, the standard is still left zero and right fire, but the electrical design of the two-pin plug should allow the fire and neutral wire to be interchanged.

How to divide the plug into live wire and neutral wire?

1. How to divide the plug into live wire and neutral wire.

First of all, it can be distinguished by color, the color of the zero wire is generally blue and black, the color of the ground wire is generally yellow and green, and the live wire is generally red or brown; Secondly, it can be distinguished by the electric pen, which shows that the higher voltage value is the live wire, and the lower voltage value is the neutral line.

2. How to connect the live wire and the neutral wire on the plug.

When wiring the plug, as long as the wiring is carried out in accordance with the way of left zero and right fire, which means that the binding post on the left side of the plug is connected to the zero wire, and the binding post on the right is connected to the live wire.

Before wiring, we must distinguish between the neutral wire and the live wire, so as to avoid reversing the live wire and the neutral wire.

3. Why should the neutral line and the live line be the same thick when renovating the line?

Because the home circuit is a relatively complete circuit, when using electricity, the current will enter the line at home from the live wire under the meter, and then flow out from the zero line under the meter, that is to say, the value of the current in the live wire and the zero line is the same, so it is required to choose the zero wire and the live wire with the same diameter thickness.

Fourth, when wiring, whether to connect the live wire or the neutral line first.

Whether it is wiring the lamp or the switch panel, it is first connected to the wire, and then to the live wire.

However, there is one thing to note, that is, when wiring the socket, if there is no loaded electrical appliance on the socket, then the neutral wire and the live wire are in no particular order.

Generally, single-phase 220V electrical appliances do not distinguish between positive and negative polarity, (the so-called live wire, neutral wire) because 220V appliances do not need the phase of the power supply. Two-pin plug appliances are designed to belong to a class of relatively safe electrical appliances, and only triangular plugs with ground wires are used for electrical appliances with large power consumption or easy to produce electric shock hazards.

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, the three ends of the three-phase electricity are called phase wires, and the three tails of the three-phase electricity are connected together and called neutral wires, also called neutral wires. The reason why it is called the zero line is that there is no current passing through the neutral line at the time of three-phase equilibrium, and then it is directly or indirectly connected to the earth, and the voltage difference between it and the earth is close to zero.

The ground wire is short-circuited to the earth through a deeply buried electrode. The transmission of mains power is in a three-phase way, and there is a neutral wire, the current of the neutral wire is zero when the three-phase balance, commonly known as the neutral line, another feature of the neutral line is that it is short-circuited with the ground wire in the total distribution input of the system, and the voltage difference is close to zero. The three phase wires of three-phase electricity have a voltage of 220 with the neutral wire, which will produce an electric shock to people, commonly known as the live wire.

Three-line

In electroengineering, the alternating voltage connected to the mains line is 220 volts (volts for short, the symbol is V), and there are two wires in the line, one of which is called the "neutral line" and the other wire is called the live wire. 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.

Two holes, three holes. In general, in the two holes, the left hole is connected to the neutral line, and the right hole is connected to the live wire.

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.

Because the electrical appliances that use two-pin plugs belong to a class of relatively safe electrical appliances, most of these electrical appliances are plastic shells, which are not easy to leak, so they can be plugged in casually.

The two-pin plug is generally a low-power electrical appliance, or the shell is an all-plastic electrical appliance, which is not prone to leakage and electric shock accidents. Appliances with metal shells and high power will use three-pin plugs (sockets) to ensure the safety of users. Electrical appliances that use two-pin plugs generally do not need to divide the fire zero line, and the higher requirements use a double-pole switch, and the fire zero line is cut off at the same time.

Regardless of whether a single-pole switch or a double-pole switch is used, normal use will not be affected, and the plug should be unplugged to ensure safety when carrying out operations that require contact with the internal of the appliance, such as replacing the bulb and overhauling.

The fire wire and the neutral line are for the line, and there is no fire zero for electrical appliances.

The wiring method of the two-hole socket, on the surface, can be divided into live wire and zero wire drops without detail!

However, from a safety point of view, it is still necessary to distinguish between priority and priority!

Socket wiring diagram.

In other words, it is necessary to carefully distinguish between the live line and the neutral line, which is safer and more reliable! For this purpose, in general, the two-pin socket needs to be wired in accordance with the way of left zero and right fire!

The socket is there, the left zero and the right fire, and the plug is a little divided, the foot is a big zero line, some are not divided, and the double insulation of Class 2 electrical appliances can ensure safety.

The two-pin power plug is not a live wire, and the neutral wire is divided.

The domestic standard single-phase two-pin plug does not have the distinction of live wire and neutral wire, and can be inserted casually.

There is a distinction between this, the live wire is the live wire, but in the process of using the two-pin plug, even if it is plugged in backwards, it is still used normally.

The two-pin plug has no live wire or neutral wire.

Of course, the mains is.

Some electrical appliances need ground to have three heads and three holes.

It's not the three-phase one of the 380.

Once the live wire and the neutral wire touch, because the voltage between the two is equal to 220 volts, and the resistance between the two contact points is almost equal to zero, the current is very large, and a huge amount of heat will be generated at the contact point of the live wire and the neutral wire, so as to send out an electric spark, and the temperature at the fire and hail staring is high enough to burn the metal wire to melt.

The voltage of the live wire to the ground is 220V; The voltage of the neutral line to the ground is equal to zero (which itself is connected to the earth). So when one part of the person hits the line of fire and the other part is standing on the ground, and the voltage between these two parts of the person is equal to 220V, there is a risk of electric shock.

On the contrary, even if a person uses his hand to grasp the zero line, if the person is standing on the ground, because the voltage of the zero line to the ground is equal to zero, the voltage between the various parts of the human body is equal to zero, and the person is not in danger of electric shock.

Connecting the neutral wire and the live wire together will cause a short circuit, which will instantly generate a large current and trip instantly.

The circuit or part of the circuit is short-circuited, such as the load and the power supply are connected together by wires, which will cause a short circuit, the current provided by the power supply will be much larger than the current provided during the path, and the short circuit is generally not allowed, if the short circuit is serious, the power supply or equipment will be burned out.

The neutral live wire is the power supply line for civil electricity, and the AC power supply voltage of the mains is 220 volts (V) (different countries are different, China is 220V). It includes a neutral wire n and a live wire L, and the ground wire is grounded (the ground is zero, PE), so it is called the zero wire. The live wire and the neutral wire are equivalent to the positive and negative poles of the power supply, and when connected together, it will cause a short circuit.

with a multimeter. Put the multimeter in the AC file 500V, pinch a meter pen, and the other meter pen is connected to the power cord respectively, the high voltage is the live wire, the low is the neutral line, and the voltage is 0 is the ground wire. The resistance of the neutral line to ground is less than 4 ohms for reliable grounding.

Use a multimeter to place the pressure difference between the 250V fire line and the neutral line, the live wire and the ground wire in the AC file, and the difference between the two values is less than 5V for reliable grounding.

Regarding the difference between the live wire and the neutral line, in the ordinary household lighting circuit, there is a voltage of 220V between the live wire and the ground, and there is no voltage between the neutral line and the ground (or the voltage is 0), so there is a voltage of 220V between the live wire and the neutral line.

First of all, the neutral live wire is defined for the socket, for example: a two-phase socket, it is the left zero and the right flame. The installer will install this rule.

There is no zero wire live wire on the plug, that is to say, it is equivalent to the two ends of a wire, the side connecting the live wire is the live wire, and the side connecting the zero wire is the zero wire.

Second, if you can't determine which side on the socket is the live wire. You can use a tester to detect and distinguish, the tester is inserted, the side of the small light on the tester is the live line, and the side where the small light is not on is the zero line.

May mine help you and make you satisfied.

First of all, there is no two-phase plug, and the neutral line of the live wire is called single-phase.

If the plug is not marked, conventionally, the left fire and the right zero.

It seems that you have some basic knowledge of electricians and have strong hands-on skills. Let's put it this way, the socket on the wall, according to the regulations, should be "left zero right fire", then, the plug you connect should correspond to the wall socket, and the socket on the wiring board is the same reason. Two-phase plug, under normal circumstances, it is no problem to plug in and reverse, and it will not be short-circuited.

It doesn't matter, even if it is reversed, it will not be short-circuited, it can be used the same.

Generally speaking. The fire line (l) is red, and the neutral line (n) is blue.

Use the red wire as a live wire.

Firewire L (live).

Neutral line n(null).

Ground g or e

According to the regulations: the socket is: left zero line; Right line of fire; In the middle (or above) is the ground wire.

The plugs are: Left Live Wire; Right zero line; Middle (or top) ground.

Electrical appliances: generally: red (live wire); blue (zero line); Two-color (ground). But there's a lot out of class.

The plug of the two wires does not need to be separate for the live wire and the neutral wire.

The two-pin plug must also be plugged into the socket of the two eyes.

Hehe, landlord, please find out first, what the word "short circuit" means.

Single-phase AC loads generally do not distinguish between live neutral lines.

The two-phase electric plug is not divided into a neutral live wire.

Summary. If there is no fuse, it will be short-circuited, too much power may also cause a fire, if there is a fuse, it is just a fuse burned. The neutral line of fire is a power supply line that refers specifically to civil electricity, the AC power supply voltage of the mains is 220 volts, it includes a neutral line and a live wire, in order to make the AC power have a very convenient power conversion function, usually the power transmission is in the way of three phases and four wires, the three heads of the three-phase electricity are called phase wires, and the three tails of three-phase electricity are connected together and called neutral wires, which are also called zero wires, and the reason for calling the zero line is that there is no current in the neutral line at the time of three-phase equilibrium, and then it is directly or indirectly connected to the earth, and the earth voltage is also close to zero.

Hello, I am sorting out the answer according to your question, please wait for a while If there is no fuse, it will be short-circuited, and excessive power may also cause a fire. The neutral line of fire wire refers specifically to the power supply line of civil electricity, the AC power supply voltage of the mains is 220 volts, it includes a neutral line and a grip of Qinggen live wire, in order to make the AC power have a very convenient power conversion function, usually the power transmission is in the way of three-phase four-wire, the three heads of the three-phase electricity are called phase wires, and the three tails of three-phase electricity are connected together and called neutral wires are also called zero wires, and the reason for calling the zero line is that there is no current in the neutral line at the time of three-phase equilibrium through Huaiyu, and then it is directly or indirectly connected to the earth, The voltage with the ground is also close to zero.
