If there is no ground wire at home, can the ground wire of the electric water heater be connected to

If your bathroom is equipotential connected, then the role of this line becomes larger, when the water heater generates electricity, the leakage protector of the water heater power plug is invalid, and the leakage protector of the power socket circuit is also invalid(It's really unfortunate, disasters continue, when multiple safety protections are problematic), and even the water heater is also electrified, and people still don't have electric shock accidents! Equipotential bonding is so awesome! But I have an unfortunate message for everyone:

For a variety of reasons, many of China's interior decoration teams have never heard of toilet equipotential, let alone do equipotential connection. There is also a relatively high cost of equipotential connection in the bathroom, and the construction of the project is inconvenient, so most families do not do it.

For many old houses or rural houses, most of them do not have ground wires, and even if there are grounding wires on the surface, most of them cannot have the effect of real grounding devices. In response to this situation that cannot be changed, when you want to buy an electric water heater to use, you will encounter a problem, there is no ground wire in the room as a wiring safety precaution, and the store does not assemble it, because it cannot give safety precautions. At this time, they will choose to assemble it themselves, and connect the grounding wire of the electric water heater to the wall as a grounding device.

Can it do the role of a grounding device? The grounding wire is a separate wire independent of the live wire and the neutral line at home, it is led by the axis of the substation and distribution room, but it is a separate protective wire with the neutral line, it has been laid to the ground row in the distribution cabinet at home, and then laid from the ground row to each power outlet; The function of the ground wire is to avoid the damage to the body caused by leakage current in the circuit or the plastic shell of the electrical product because of common faults, when the leakage current passes through the circuit or the plastic shell of the electrical product due to common faults, the leakage current will be injected into the ground through the grounding wire, so as to prevent the electricity from flowing through the body;

Since it is a grounding wire, then there is a corresponding specification, such as a grounding wire at home, when we use an insulation resistance tester to measure, its resistance value can not exceed 4 ohms, this scalar room to ensure that the leakage current is not easy to cause harm to the body when the electricity is discharged, and the leakage current will be very likely to cause harm to the body when exceeding this standard value; But any electric water heater equipped with a leakage protection switch will appear this line. It can also be called a "ground wire", but it is not the same as the ground wire that everyone usually knows - the general ground wire is connected to the top of the plugAccording to the pin in the middle of the three-pin plug, it is connected to the ground wire in the power outlet. This grounding wire is connected to the nail that fixes the support frame of the immovable water heater.

It can be understood as: immediately connected to the wall.

Yes, you can; Generally speaking, there is no danger, and it can also be used as a ground wire after being connected to a wall.

If there is no ground wire, it is possible to connect the ground wire into the wall during the installation of the electric water heater, which can also be used safely in this way.

The ground wire of the electric water heater can be connected to the inside of the wall or to the bottom of the floor, in fact, it is okay, the ground wire is actually not in any danger as long as it is connected, everyone should pay attention, after all, it is not 100% safe, and sometimes it is necessary to pay attention to whether there is an abnormality in other electric water heaters.

In the old buildings in the city, you can ask professionals to check the grounding treatment of the building, try to use the grounding device of the building for grounding, you need to consult professionals, do not connect to the lightning protection facilities of the building by yourself, the consequences of leakage are unimaginable. In addition, when it is not installed, the professional installation must reliably connect the water heater with the ground, and in some special circumstances, the leakage protection at home will be disconnected, so as to ensure the safety of life. If the ground wire.

It's disconnected, and I really can't connect.

<> if the ground wire is not qualified, we must find a professional to repair the ground wire. Resolutely do not put radiators.

Water pipes, as grounding wires, this is dangerous! And find the source of the ground wire, find out whether the ground wire in the building is not in good contact, or the wire can be an electric water heater.

A line of ground that leads to the ground and acts as a ground wire. Poor insulation performance of electric water heaters or humid use environment will produce a certain amount of static electricity, and in serious cases, electric shock accidents will occur. So it can be grounded without a ground wire.

If the electric water heater does not have a grounding wire, it is very dangerous, if the household power cord does not have a grounding wire, it can be modified if possible, in the distribution box.

Lieutenant will replace the cross-sectional area of more than 6 square millimeters.

and connect the ground wire to the public ground wire pile, and install the air leakage separately in the use of electric welding.

When iron welds circuits, due to the electrification of welded iron, electrical maintenance personnel must break through the integrated circuits in electrical appliances. Friends who use computers sometimes ignore the grounding of the host case, in fact, connect the host case with the ground wire.

It is entirely possible that the socket at home does not have a grounding wire. For example, some houses in rural areas, urban fringes, or urban shantytowns that have not been renovated.

It is true that such homes do not have protective grounding wires. If the easiest way for these residents to install is to remove the power cord after the water is hot, and then use it, do not connect the ground wire indiscriminately, if something happens is a matter of human life, it is a major matter of human life, and it is better not to connect it than to connect it indiscriminately.

It should be connected from the whole underneath the floor, and then a secure socket should be installed, which is a very good way to do it, and it is safe and reliable.

It should be connected to the wall, so that the child will not come into contact with these things, and the water will not easily flow to the line.

The water heater must have a ground wire, and it is not possible to have a ground wire, so it is recommended to find an electrician to think about it.

It is not safe at all, the water heater is prone to fire without a ground wire, and it is easy to **, easily**, and there is a risk of electric shock.

It's not safe to use at all, and there is a high chance of causing a fire, so you should replace it with another one.

I think it is very unsafe, because this situation is very easy for us to cause harm to our bodies when using the electric water heater, or directly cause heavy electricity, causing potential safety hazards to our lives.

When choosing an electric water heater, you must choose an electric wall with performance, but also have brand awareness, and there must be a 3C anti-counterfeiting logo, do not blindly listen to others when choosing, and practice yourself.

Be sure to connect the ground wire when installing the electric water heater.

This is for safety. Standing on the ground and lifting the surface, the body potential is the same as the ground potential; If the electric water heater is connected to the ground wire, the potential of the water heater and the hot water will be the same as the potential of your body, so there will be no electric shock, no current will be generated, and it will be safe. The old Huaibi ground wire must be buried in the ground, so that its grounding resistance is small; It is best to connect to the wall as well, but it is not possible to connect it to the wall casually, the conductivity of the wall is very poor, and it must be grounded.

It can be connected directly to the wall.

But this grounding method is not very perfect, the perfect way is to use a special grounding wire to connect to the grounding terminal of the main power supply of the home.

Directly connected to the wall, although grounding protection can also be realized, but there are large safety hazards, such as rust of the screws used, excessive contact resistance of each contact surface of the grounding line, etc.

If possible, it is advisable to consider using a special grounding wire to direct the grounding terminal to the grounding end of the main power supply.

The electric water heater itself has two grounding wires, one of which is connected to the common grounding body at the end of the transformer through the grounding wire of the outlet. The other is to nail it directly to the wall and ground it to the wall of your own home. The walls must be conductive.

No matter what kind of wall it is, as long as it is a fake wall made of gypsum board by yourself, it will be fine. Therefore, nailing the grounding wire to the wall can also play a grounding role. After the electric water heater leaks, the leakage current flows into the earth through the grounding wire, preventing the current from passing through the human body and preventing the user from being electrocuted.

There are strict standards for the grounding body, which is controlled by the grounding resistance. The wall has slightly less resistance, and there are large and small rebars (although there are other factors that have a smaller impact). So this grounding is unstable.

We do this grounding once also for safety. No matter how much it can improve the safety factor, it will be improved anyway. Because many families don't have a check-in line at all (e.g. in vast rural areas), users here need to ask again.

Can I use an electric water heater without a grounding wire? The grounding wire is a separate wire from the homefire wire and the neutral wire, from the center line of the border room, but like the neutral wire, it is a separate protective wire, which is laid on the floor inside the distribution box of the house and then from the ground to the individual outlets.

The grounding wire plays a very important role in the home, and setting the grounding wire can reduce the probability of electric shock. In short, the leakage of the water heater has the effect of preventing direct flow into the human body, and even if the grounding wire is set, even if it leaks, it will not flow to the earth and to the human body first. However, it should be noted that the grounding wire should be tested with resistance, and the resistance value should not be greater than 4 ohms.

This value cannot be exceeded. So there is no grounding wire at home, and the water heater grounding wire cannot enter the wall and cannot be used! Because the resistance value cannot be tested when installed on the wall, it can not pass the resistance at this time, it cannot be protected, and in serious cases, it can also charge the ground wire.

If there is no grounding wire, how to deal with the water heater to reduce electric shock?

The water heater can be heated to a pre-specified temperature. When taking a bath, you can unplug the power or cut off the circuit switch of the electric water heater in the distribution box. Alternatively, you can purchase a qualified electric water heater with an electric wall.

This water heater is specially designed for use where there is no grounding wire, don't forget to install a qualified leakage protection switch. Also, remember to have your electric water heater serviced regularly. Because a lot of leakage is also caused by not paying attention to maintenance.

At present, there are two main types of electric water heaters on the market. One is an electric water heater and the other is two types of electric water heaters. There are two types of electric water heaters commonly used in our daily life.

This electric water heater is designed with leakage protection, which can avoid safety problems to a certain extent. At the same time, this water heater has a protective wall and has its own grounding, which is easy to use. If you do it yourself, there may be loopholes and defects, so it is best to find a professional electrician to operate it.

In this way, the electric water heater may have a separate grounding design.

There is no ground wire at home, and the ground wire of the electric water heater can not be connected to the wall, nor can it be used, because we cannot guarantee whether the grounding resistance at this time is qualified, and it can be said that the grounding resistance of this method is unqualified, so it cannot play a protective role, and in serious cases, it may also make the ground wire live.

No, any electric water heater with an electric wall installed will have this wire. It can also be called a "ground wire", but it is not the same as the ground wire we usually understand - the general ground wire is connected to the plug and is connected to the ground wire in the socket through the pin in the middle of the three-pin plug. This ground wire is attached to the steel nail that holds the electric water heater bracket in place.

It can be understood as: directly connected to the wall. In other words, the electric water heater itself has two ground wires, one of which is connected to the common ground body at the transformer end through the ground wire in the socket.

The other is to nail it directly into the wall and ground it on the wall of your own home.

No, I think you should reconnect it again, don't be lazy to connect the bottom line of the water heater into the wall, this is very bad, and there will be a lot of trouble in the future.

Of course, it is very possible, but you must pay attention to the safety of these and connect it into the wall on the premise of ensuring safety.

No, because it is difficult to find hidden dangers in the access wall, and it will only be easy to find if there is a problem with it on the bright side.

OK. This method is also very simple, and it is not too hassle-free, and it is also relatively cost-effective.

Can the ground wire of the water heater be used in the wall during decoration? Many homes have installed it incorrectly, no wonder there is a leak!
