Because what socket should be divided into left zero and right fire

Prevents the current from passing through the heart and is positively dissolved.

Because most people hold their girlfriends or mistresses with their right hands

Just walk on the right.

Maybe it's the reason for what is in line with it, the era of the common use of incandescent lamps, few people pay attention to the two wires connected to the lamp head or connected to the socket, that is the fire wire and that is the zero line, and then there is a fluorescent lamp before the light is opened to measure the live wire, sometimes the system only has a fluorescent lamp, it is directly solved on the lower side of the gate box, and then there is an extra ground wire in the socket, so the ground wire is found out first when wiring, and there is a mark of L and N on the socket later. So there is a left zero right fire said, and then there is a leak switch to find out the ground wire more seriously, otherwise the use of the socket will automatically cut off, at first whether it is a few bedrooms and no matter how large the area and no matter how many electrical appliances you have in your home, only an air switch in the corridor is to control your home, whether the lamp is broken or the socket is broken, to find your own switch in the corridor to pull down, you can rest assured that the operation, and then there is a household shunt controller, there are rows of switches, the lamp is the lamp socket is the socket, It is not a self-installed circuit, how many switches are broken when repairing, but sometimes when touching the copper, it may be timid, in short, more and more standardized, more and more refined, but not more and more safe, there is a danger to repair electricity, you need to be cautious, always get the insulation under your feet, regardless of whether there is electricity or not.

In the case of an electric shock, the current goes to the right side of the body, but not to the heart.

The switches of electrical equipment in China are all fire lines, or all fire is broken...

Just like when you drive, you always have to use your hands to get behind the wheel, right? You can't use your feet, right? This is the rule.

There is no standard, no safety. Uniform safety standards. And not one person one standard.

Let's put a fuse in the 3 corners in the line of fire.

Yes, the left zero is the right fire, but it depends on the annotation of the interface, the L interface is connected to the live wire, and the N interface is connected to the zero line.

Yes, the wiring principle is to face the socket, the left zero wire and the right live wire, in addition, the qualified socket is marked with a definition next to the binding post, L is the live wire, N is the neutral wire, G or GND is the ground wire, and the wiring will not be wrong according to the definition.

From the front of the socket, you have zero on the left hand side and a fire on the right side. From the back of the socket, it is marked that N is zero and L is fire. Dividing the left zero and the right fire is mainly a safety consideration. The domestic standard is 3 poles. There is also a protective grounding e.

Yes, people distinguish left and right from the socket panel, in fact, the internal wiring of the socket panel will generally be marked with two ports, L and N, of which L is connected to the live wire and N is connected to the neutral wire.

The fire zero wire connection method is that the person faces the socket panel, the left hole is connected to the zero wire, and the right hole is connected to the live wire.

People are divided into zero live wires on the back of the socket, left zero and right phase, remember to also have reliable grounding! That's how it stays safe.

Yes, the fire is l zero is n socket terminal is marked, to be wired according to the mark.

Judging from the front of the socket, whether it is a three-hole socket or a two-hole socket, it is "left zero and right fire." ”

From the back, the wire connected to the socket L sign is a live wire, and the wire connected to the N sign is a neutral wire.

Generally, the line of fire is red or orange; The zero line is generally a blue line; The yellow-green overlay line is the ground line.

That is, pay attention to the socketsFrontLook, it's the left zero and the right fire.

There are regulations on the left zero and right fire, and there are regulations on the height of the socket, the position, the height of the switch, the position, etc.

The front of the person facing the socket panel is zero on the left and fire on the right.

The usual so-called [left zero right fire] is to face the panel of the socket to distinguish, you understand correctly.

According to what you said, it is not very standardized, in fact, the binding posts on the back of the socket are marked with letters or symbols representing zero fire ground wire, I hope it can help you.

Normal red is fire, blue is zero, and yellow and green is earth.

The correct connection of the socket is: left zero and right fire.

There are signs on the socket, L is connected to the live wire, N is connected to the neutral wire, and PE is connected to the ground wire.

No, it must be left zero right fire, this is the industry norm, and it is formulated to ensure the safety of electricity.

Generally, household sockets are divided into three holes and two holes, the left side of the two-hole socket is the zero wire, the right side is the live wire, and the three-hole socket has an additional ground wire. Among them, the live wire comes from the power plant, the zero line is the return line, which is generally to return to the voltage device to contact the ground, and the ground wire refers to a protective line laid in addition during the decoration. The main reason why the socket is set to the left and right fire is actually to protect the electricity user for electrical safety, if the left zero and right fire become left fire and right zero, it will be quite dangerous.

The left fire and the right zero are to protect the electricity user, and everyone knows that people are not insulators, but can conduct electricity. Therefore, when we touch the socket, both the left and right hands, it is very easy to get electrocuted. When the voltage is low, the human body will have a crispy numb feeling when exposed to the current, and the electric shock will generally be divided into two reasons, one is to cause the human body to faint and shock, and the other is to die on the spot.

Although both the left and right hands are prone to electric shock, when the neutral line is on the left and the live line is on the right, it will protect the human body and reduce the harm caused by electric shock.

The difference between electric shock in the left and right hands The human body is a conductor, but the effect of the left hand contact with the current is completely different from that of the right hand. When a person's right hand is electrocuted, the current will pass through the person's right hand to connect to the body and form a pathway through the left foot, which will cause the whole body of the human body to be electrocuted. When the left hand is electrocuted, although the current will also touch the body through the left hand and form a pathway through the right foot, although it is also a full-body electric shock, but this time the current will directly pass through the heart and cause electric shock, shock and even death.

In general, the right hand is more flexible than the left hand, and the probability of the right hand of the person being exposed to electricity is greater than that of the left hand, and even if it is exposed to electric current, the current does not pass directly through the heart. Therefore, the setting of left zero and right fire is actually to minimize the probability of reducing the probability of cardiac electrocution.

The harm of left zero right fire becomes left fire right zero When the left zero right fire becomes left fire right zero, the electric shock current of the human right hand will directly pass through the heart to cause shock, and even die on the spot, most people are right-handed at the same time as the electric shock, they will habitually throw out, but when the right hand touches the zero line, the current instantly passes through the heart, basically there is no time to react, and the harm is huge.

Because the human heart is on the left, and the fire wire is electrified. The left zero and right fire are to reduce the damage of human electrocution, and the left fire and right zero are not good.

Left-zero-right fire is a universal wiring principle. The left fire and the right zero can also work normally, but it will cause some safety hazards, so it is not used.

Because such a setting is conducive to the operation of the whole, the reverse is not possible.

"Left zero right fire on the ground" is a general wiring principle, but not a hard requirement, although for most electrical appliances "left fire right zero" can also work normally, but will cause some safety hazards.

Left zero right fire on the ground

In daily life, we often use two-foot sockets and triangle sockets, which is a little common sense, for the socket there is a saying that "left zero right fire on the ground".

We know that for 220V household electricity, there are live wire (L), neutral wire (N) and ground wire (E), where the ground wire is the protective wire connecting the earth, the potential is zero, the live wire and the neutral wire are working wires, where the live wire is high potential, and the neutral wire is low potential.

Under normal circumstances, it is the live wire that will cause electric shock to people, so a reasonable and unified wiring method can reduce the probability of electric shock.

Two-pronged sockets and triangular sockets

When we usually use two-pin plugs (such as desk lamps, hair dryers, etc.), we do not distinguish between the left and right sides of the plug, because electrical appliances with two-pin plugs do not distinguish between positive and negative poles when using AC, while the live wire and neutral wire are determined at the socket end. For the triangle socket, the ground wire above is fixed, and it cannot be mistaken under any circumstances, and then the bottom left is the neutral wire, and the lower right is the live wire.

For the two-foot socket and the triangle socket, even if most of the electrical appliances use "left fire and right zero" will not be affected, but for the same system, the unified wiring method is conducive to wiring and subsequent maintenance, and can also reduce potential safety hazards in the process of use.

Reduce safety hazards

Some electrical appliances or sockets with switches, using a single-pole switch, that is, the switch only controls a line, in principle, this line must be a live wire, the equipment must be designed in accordance with the "left zero right fire", if the wiring uses "left fire right zero", then although the electrical appliances stop working after the switch is disconnected, the electrical appliances themselves are also connected to the live wire, which will bring potential safety hazards.

There is a widely circulated saying that relevant studies show that due to the majority of right-handers in life, when the right hand plugs and unplugs, the probability of the thumb touching the metal electrode is higher, and the probability is "upper electrode", "left electrode" and "right electrode", so there is a "left zero right fire on the ground wire" provision, because only when people come into contact with the live wire, electric shock will occur.

In real life, electricians may not strictly follow the principle of "left zero right fire", so when we overhaul the circuit by ourselves, we must ensure that the power supply is completely disconnected, and use a voltage detector to detect and ensure 100% safety before operating.

Three-phase electricity

Left zero right fire ground wire" is aimed at two-phase electricity, for 380V three-phase electricity, there is no such statement, but three-phase electricity will have a phase sequence problem, different phase sequence, will make the three-phase motor steering different.

Left zero and right fire can reduce the damage to the heart when the human body is electrocuted, and left fire and right zero will increase the probability of electrocution death, no.

The left zero and right fire of the socket is in line with the scientific safety design, and the left fire and right zero will not work and will be dangerous.

Because this is a natural circuit system, which is in line with the laws of nature, it is not possible to change the position.

Because it is alternating current, the wiring method has no effect on the electrical appliance.

The socket has one or more sockets that can be plugged into the wiring of more than one circuit, through which various wiring can be inserted, so that it is convenient to connect with other circuits. Through the connection and disconnection between the line and the copper part, the connection and disconnection of the circuit of the circuit can be finally achieved.

Hehe, there is no effect, the electricity at home is alternating current, the so-called alternating current is also called "alternating current", referred to as "alternating current". Generally refers to a voltage or current whose magnitude and direction change periodically over time. Its most basic form is a sinusoidal current.

The standard frequency of AC power supply in China is 50 Hz, and 60 Hz in Japan and other countries. Alternating current changes over time can manifest themselves in a variety of forms. Different forms of alternating current have different application ranges and effects.

That is, the left and right of the live wire and the neutral line do not affect the use of electrical appliances, you can read more junior high school physics books, which are very helpful.

The single-phase sockets used at home have two-hole and three-hole ones, but there is only one way for them to wiring correctly:

Left zero right phase (fire), ground wire (three-hole) on the top, not in this way of wiring are wrong, do not meet the requirements.

Because it is alternating current, the wiring method has no effect on the electrical appliance, but there are some cases that will affect the safety of electricity, for example, the threaded part of the lamp port should be connected to the live wire and so on.

Which electrician did this, you can deduct his wages! Extremely irresponsible!

It does not affect the normal use, but it has a certain impact on safety, and it will also cause trouble for future maintenance.

The main thing is that there is no positive or negative difference between alternating current, so it has no effect on electrical appliances. But for switches, it is generally to control the live wire, so it is safe, and the live wire is the same no matter which side of the socket.

There is no impact on electrical appliances, alternating current, there is no positive and negative electrodes, there is no impact on the use of electrical appliances, there are mainly potential safety hazards, why do you want to do it with the right hand, because most people do things with the right hand, in order to prevent the thumb from touching the right insert with the thumb and causing an electric shock accident, so it is stipulated that the left zero right phase,

Because it is due to alternating current, it has no effect on the use of electrical appliances!

The purpose of the left zero right fire is to use electricity safely, safety first, in order to make it more convenient to operate and ensure the personal safety of the operator, and the convenience of maintenance and the convenience of the brake have nothing to do with it.

Analysis of the degree of harm of electric shock in the human body:

1. Left hand electrocution, the current passes through the person's left hand and body through the right foot to form a pathway, because the human heart is on the left, and the current forms a circuit in the human body, most of the current will pass through the heart, so that the electrocuted person will directly shock or die in a short time.

2. If the right hand is electrocuted, the current passes through the person's right hand and body through the left foot to form a pathway, and only part of the current passes through the heart, which will cause less damage to the electrocuted person.

Parsed by bare wires:

If the wiring of the line is left zero right fire, the probability of electric shock of the right hand of the person is greater than that of the left hand, even if the electric shock, the current will not pass directly through the heart, relatively speaking, the right hand is more agile than the left hand, will instinctively throw away, the probability of the electric shock of the left hand of the person will be much smaller than the right hand, and the probability of hitting the zero line is greater than the fire line.

In fact, whether it is a left-hand electrocution or a right-hand electrocution, as long as a loop is formed, the current exceeds 10ma, which can make a person die in a short time, the only difference is that the heart is not so injured when the electrocution occurs, and the electrocuted person still has a chance to rescue, the setting of the left zero and right fire is to minimize the probability of cardiac electrocution.

In short, the setting of the left zero and right fire is to minimize the probability of electric shock to the heart, so when reaching out to the electricity, try to attack with the right hand.
