There is no ground wire at home in rural areas, does the leakage protector trip, and does the leakag

The leakage protector of rural families is also called a safety device, because the current buildings in the city are equipped with leakage switches, that is, double P leakage switches. Safety devices are mainly used in rural areas, and they do act as a leakage trip。When the leakage current reaches 30 mA, they will trip automatically

In fact, they differ from the use of ground wires. They protect the leakage current loop of the circuit, while the ground wire protects the leakage current after the metal case of the appliance is charged.

When the leakage protection device is not working, the current is largely transmitted along the ground wire. To protect people from electric shock when they come into contact with live appliances, there are indeed different places. You can see it this way, these two types of protection are superimposed protection, in the case of leakage, the leakage switch does not work, and the current will flow down the ground wire, so as to ensure personal safety.

The grounding wire is connected with the metal shell of the household appliance, and the other end is connected with the grounding system. When a leakage occurs, the leakage current will flow into the earth through the ground wire and not through the human body. This can prevent the occurrence of electric shock accidents; If the leakage protection switch is installed at this time, the leakage protection switch will trip; If the leakage protection switch is not installed, the leakage current can only be diverted by the grounding wire.

In the case of no grounding wire, the leakage protection switch is still effective, and the operation of the leakage protection switch has no effect on the grounding wire. But if the grounding wire is not installed, personal safety is indeed a layer of protection, and such a design is actually to save money in rural areas. In short, in the absence of a ground wire, if a leakage occurs.

In general, the leakage protector will trip, but only if the leakage current reaches 30 mA. On the other hand, the ground wire is active protection, while the leakage protection switch is passive protection, and it is best to install ground wire protection for safety use.

That would certainly be useful. If there is a leakage situation, and after the control limit is reached, it will trip for protection.

It will trip, but for safety reasons, it is still necessary to install a ground wire.

The leakage protector will definitely trip, and we usually have to pay more attention to the safe use of electricity.

Do not stick wallpaper and put an end to glue. Suspended ceilings, just cover the fresh air and air conditioning lines, and use as little blockboard as possible. What's the horse? The foreman said suspended ceiling.

There is no ground wire at home, does the leakage protector work? Can the wire leakage be tripped for protection?

Nothing is absolute, and it can definitely play a certain role in protection, but it is also necessary to check and maintain it regularly.

Personally, it is recommended to install ground wires as much as possible, with the popularization of household appliances in rural areas, there will be more and more metal shell electrical appliances in rural areas, therefore, good grounding can indeed ensure the safety of personal electricity.

Whether it is in the countryside or in the city, it will basically trip now, and the flower that does not trip is the scene of the fire.

Leakage may not be slag in general, but sometimes it will trip in serious cases.

Daily testing and maintenance is required, and the leakage protector will be damaged Press the test button at least once a month If it is pressed and does not trip, it must be replaced.

If there is a leakage protector, there must also be a grounding wire.

The leakage protector cannot replace the grounding wire, and the grounding wire connects the metal shell of the electrical appliance with the earth when the electrical appliance is used. Under normal circumstances, the shell of the electrical appliance is not electrified, and it will not be dangerous for people to touch it. However, there are always some unpredictable reasons in the process of electricity use, which causes the metal shell of the electrical appliance to be electrified.

The leakage protector is determined by comparing the current of the live wire and the neutral wire. When the difference between the two currents reaches the set value, the leakage protector will automatically trip and cut off the circuit.

If the leakage protector is installed without grounding the wire, once the metal shell of the electrical appliance is electrified, only when the person comes into contact with the metal shell, the leakage phenomenon will occur, and the leakage protector may cut off the circuit in time, but the current has flowed through the human body, which will cause harm to the human body.

If good grounding is ensured, as soon as the electrical appliance is energized, there will be current flowing to the ground, and the leakage protector will cut off the circuit when the leakage phenomenon occurs, reminding the circuit to be repaired in time to eliminate potential safety hazards.

Several situations in which the "leakage protection switch" does not trip when the human body is electrocuted:

1. The person stood on an insulated wooden bench and touched the fire wire with one hand and the zero line with the other. In this case, there will definitely be an electric shock, but the leakage protector will not trip, because the human body does not touch the earth and does not produce leakage.

2. If a person stands on the ground and one hand touches the line of fire, the person will be electrocuted. If the leakage current does not reach 30 mA, the leakage protection will not trip, and the minimum leakage protection starting current in our household is 30 mA. Because most shoes are insulated, but the insulation effect is not very good, so the hand touches the fire wire and has the feeling of electric shock, but the leakage current does not reach the jumping standard, in this case people can break free.

3. If the wiring at the upper end of this 1P+N leakage guarantee is wrong, the leakage guarantee will not trip. Because the n position of this leakage is not on/off, it is also open even if it trips up and down n points.

4. The leakage warranty will definitely not trip if it fails or is broken, and the quality of the leakage warranty can be judged by a simple test. In the case of power-on, press the yellow test button, if it trips, it means that the leakage is intact, if it does not trip, it must be replaced even if it is replaced, so it is very necessary to press it once a month.

Hello, the installation of the leakage protector does not trip if it is electrocuted, first, the leakage protector is damaged.

Second, the resistance of the human body is relatively large, and the leakage current cannot reach the action value of the leakage protector.

The leakage current of the household leakage protector is 30mA. As long as the leakage current reaches 30mA, the leakage switch will operate immediately.

30ma=。

When an electric shock occurs, how many ohms does the resistance exceed the leakage switch will not trip, the calculation is:

30mA = ohms.

The above calculation is the maximum value, beyond this resistance, the leakage protector will not trip in the event of an electric shock.

A leakage protector is installed at home, why people will not trip if they are electrocuted, these 3 points can not be sloppy!

It's broken, or it doesn't exceed the rating.

Or maybe it's too damp in a certain location.

Abstract: Ground wire refers to the diversion of excess electricity into the ground. Protect against electric shock. The leakage device is installed to allow timely tripping in case of short circuit or other unexpected conditions. If it is not installed, then it will not trip. At the time of the electric shock.

There is no grounding wire at home to ensure that the leakage will not trip.

Is it safe for the air conditioner to have a leakage protector without a ground wire?

Yes, it's okay, but although the power will be cut off when you are electrocuted, it is also more dangerous. It's safer to put it on.

The air conditioner has leaked electricity The leakage protector does not trip When a person is electrocuted, the leakage protector will trip Is this the case.

When there is a short circuit, or when various accidents occur. will jump.

It is not short-circuited, that is, the live wire and the shell of the air conditioner are glued together, will the leakage protector trip.

If the case is metal, it will.

Summary. Hello, it is effective, the leakage switch, as the name suggests, is to protect us in the event of leakage. The way to protect is to cut off the power supply (trip) - the purpose of cutting off the power supply is twofold

1.Cut off the power supply before a person is electrocuted to prevent problems before they occur;

2.Cut off the power supply after a person is electrocuted, reduce the time of electric shock, and reduce the hazard of electric shock.

So how does it know if there is leakage in the line? The answer is by comparing the currents on the neutral and live wires. Normally, the magnitude of the current on the neutral line and the current on the live wire is the same.

Leakage was generated, proving that a new loop was created, which would inevitably result in different currents on the two wires – and the leakage switch tripped.

Hello, very happy to serve you, if my answer is helpful to you, please move your fortune to give a like, I am happy to serve you, I wish you a happy life, thank you! 珞珞

Hello dear and happy to answer for you. It is also useful to find out the leakage protector without a ground wire for you here. 1. Many electrical appliances will require the installation of ground wires, such as bath bombs, water heaters, and air conditioners, which have relatively large power, and must be connected to the ground wire.

However, if there is no ground wire, only a leakage protector is installed, and it can also work. Because there is no direct connection between the two, the ground wire and the leakage protector are both a kind of protection device, and the combination of the two can play a double role in protection. 2. If there is no access to the ground wire, the leakage protector needs to be installed, if there is a circuit failure, such as a short circuit, open circuit problem, in this case, it will lead to the leakage protector to be powered off in time, which can be protected to avoid the danger of electric shock.

3. The ground wire is when the electrical shell is electrified, if the person accidentally contacts the shell, then the vast majority of the current will not pass through the human body, and the underground will be transferred directly through the ground wire, which can avoid the danger of electric shock. 4. If there is no ground wire, but there is a problem with the leakage protector, it loses its effect, and once there is leakage, the risk of electric shock will increase. Therefore, both of these should be installed, and the leakage protector should be checked regularly, so as to play a double protection role.

Useful. If there is no ground wire connection, the leakage protector is equivalent to an electric shock protector, that is to say, the equipment will not trip in the case of leakage, and only when the human body contacts and causes the electric shock current to flow into the ground, it will play a protective role.

About 80% of the electric shock of the human body is caused by the human body touching the single-phase phase line, and the electric shock current forms a loop through the phase wire-human body-earth, causing harm to the human body. The promotion of leakage protection switches has a great effect on preventing leakage electric shock, reducing personal electric shock accidents, and preventing equipment leakage.

The use of leakage protection switches plays an important role in improving the level of safe electricity use, reducing personal electric shock accidents and equipment leakage protection, and can also avoid many electrical fire accidents.
