What is the specific role of the equipotential terminal box installed in the bathroom?

Many friends in the decoration of the house, in order to facilitate and save trouble, there is no very attentive, and then if you encounter some irresponsible workers, there will be a variety of details when decorating, and there will be a lot of missing things, so it is very easy to have potential safety hazards, when decorating, it is recommended to supervise yourself, so that you are not afraid of any problems, the bathroom shower should be installed with this box, it can protect the safety of the family. The bathroom must be equipped with this box, it can save your life at a critical moment, and I regret that I only found out now.

The bathroom is a place where we use a lot of water, we take a bath and wash clothes are here, the environment is quite humid, when the family invites the master to install the shower, you should pay attention to the box next to it, but if you don't pay attention, some masters will not give you a lot of things, and may be less than a lot of things. This box we call the equipotential terminal box, it is a kind of anti-electric shock device, if it is removed, there will be potential safety hazards, so you must ask a professional master to do it when decorating.

Many families in the use of electrical appliances, there has been an electric shock, and generally in the bathroom, the bathroom water is quite a lot, there is also water in the electrical appliances, so it is easy to leak electric shock accidents, if there is an equipotential terminal box installed in the bathroom, then even if it is leakage, it is not afraid of hurting the family, pay attention to the high-power electrical appliances at home and connect it together, in order to better protect the safety of the family.

When installing the shower in the bathroom, pay attention to the wire installed on the side of the shower, now technology is more and more developed, the water heater is used when taking a bath at home, the water heater needs to use electricity, if the water makes some parts damp when bathing, it is easy to malfunction, or even leakage electric shock accident, at this time there is an equipotential terminal box, you can prevent the occurrence of electric shock accidents.

There are many electrical appliances used around us in life, which bring great convenience, but there are also potential safety hazards, so we should pay special attention when installing.

It is to test the qualification of the lightning protection system and check whether the potential is repeated grounding, which can protect the power system at home. But there are also potential safety hazards, so special attention should be paid to when installing.

The most important thing that is easy to be ignored in the bathroom, equipotential connection terminal box, can save lives at critical moments.

The equipotential terminal box will connect the protective trunks, water and gas metal pipes, heating and refrigeration and cooling systems, and metal components of the building in the building to protect the electrical appliances in the bathroom.

If this equipotential terminal box is installed, it can ensure the normal use of the whole electricity, and there will be no leakage, so that the room can become very safe and reliable, and there will be no fire.

If your home is a new house, stainless steel water pipes, copper water pipes need to be connected to the equipotential terminal box. These are all metal pipes. If the home decoration uses PPR pipes, it is non-conductive and does not need to be equipotential.

If your home is an old house with cast iron main water pipes, the equipotential must be connected, and there is no reserved equipotential terminal box.

Because this detail is related to personal safety, the reasons are as follows:

1.The electric water heater at home, the zero line touches the shell, and the water heater is working normally, the current passes through the exposed metal, just you touch the metal, and this voltage is greater than 12 volts, then the human body will be electrocuted, the focus here is the water heater.

2.Just on a rainy day, the lightning struck the building of your house, coincidentally you are taking a bath, and there happens to be an electric current conducted through the metal pipe to the metal frame such as the shower faucet, and more coincidentally you touch the metal shelf, and the voltage is greater than 12 volts, then you will be electrocuted, the focus here is the lightning split.

Therefore, when decorating the bathroom, should the equipotential terminal box be connected? It mainly depends on the following four points.

1.See what kind of water pipes are used in your home?

2.See if the developer's equipotential is qualified?

3.The socket at home must be equipped with a leakage protector.

4.The ground wire of the socket board must be connected!

Then it is to see if the equipotential reserved for you by the developer is real or fake? If the real equipotential iron sheet is welded to the main steel bar of the building, it can form a "Ferrari cage" effect, and the fake equipotential is not connected to the main reinforcement at all, which is just psychological comfort!

The so-called equipotential bonding terminal box is suitable for general industrial and civil building electrical installations, in order to prevent intercontact electricity and fire caused by grounding system failure, and can effectively prevent the interference of damage accidents caused by lightning protection system failures and overvoltage of electronic information equipment. Local equipotential connection in the toilet can make the toilet at the same potential without potential difference, so as to prevent electric shock accidents. There are detailed regulations in the National Building Standard Design Atlas, 15D502 Equipotential Bonding Installation.

The equipotential connection terminal box connects the steel mesh in the building such as high-rise residential, hospital, swimming pool, etc., the PE wire terminals, sockets, upper and lower water pipes, heating pipes, gas pipes, metal bathtubs, bath racks, shower handrails, refrigerators, air conditioners, and conductive floors in the bathroom to the terminal boards in the respective equipotential connection terminal boxes, so as to form their respective equipotential bodies and protect the safety of people and equipment.

Yes, it must be connected with the meter box, the grounding wire of the general distribution room is reused, can be connected with the user's toilet, and can be used for bathing equipment or the grounding of the socket.

I think it is very necessary to borrow, because it can reduce the voltage, prevent some electrical accidents, and cut off the power supply when necessary, especially in the humid environment of the bathroom, which is very necessary and can reduce a lot of hidden dangers.

Need. This will be safer, and you can protect yourself well in the event of metal leakage.

It is also possible for the newly renovated house not to install a potentiometric box, because the current PPR tube is mostly used for decoration, and then it is non-conductive.

The positioning phase of the toilet mainly plays the role of safety protection and real-time monitoring of voltage. Because the area of the bathroom is small, but there are many high-power electrical appliances, there are certain hidden dangers in safety.

That is, if there is a leakage electrical appliance in the bathroom, a wire can be drawn from the shell of the equipment, connected with the terminal of the equipotential box, and the grounding wire is used.

It prevents the possibility of electricity leakage caused by the use of water and electricity in the restroom.

Connect a case or metal part such as a device to a ground wire. It is used for repeated grounding in the power distribution room, and is also used in the bathroom with bathing equipment for residents, and for the grounding of bathing equipment and related sockets. The legend is usually denoted by.

The equipotential coupling terminal box is suitable for the electrical installations of general industrial and civil buildings, in order to prevent the first and fire caused by the failure of the inter-contact electricity and anti-grounding system, and the equipotential coupling can effectively prevent the interference of damage accidents caused by the failure of the lightning protection system of the building and the overvoltage of the electronic information equipment.

The equipotential connection terminal box connects the steel mesh in the building such as high-rise residences, hospitals, swimming pools, PE wire terminals, sockets, water and water pipes, heating pipes, gas pipes, metal bathtubs, bath racks, shower handrails, refrigerators, air conditioners, and conductive floors in the bathroom to the terminal boards in the respective equipotential connection terminal boxes, so as to form their respective equipotential bodies and protect the safety of people and equipment.

The meaning of equipotential is "to connect the enclosure or metal part of a device, such as a device, to the ground wire". It is generally used in the power distribution room for repeated grounding, and is also used in the bathroom with bathing equipment of residents, and is used for the grounding of bathing equipment and related sockets.

According to the "Code for Lightning Protection Design of Buildings", it is required that the residential power supply system should be grounded for total equipotential connection, and the bathroom should be partially connected; Moreover, the position of some equipotential settings is unreasonable, and the reinforcement cannot be connected even if it is connected by itself in some frame structures.

What is the function of the equipotential terminal box, its function is to prevent electric shock or cause accidents such as **, mainly used for grounding in the power distribution room, and can also be used for the grounding of bathing equipment and sockets in the bathroom. Equipotential installation in the toilet is to avoid sudden situations during bathing, which will cause current to flow into the water outlet and avoid electric shock accidents.

What are the construction standards for equipotential installation.

When installing, it is necessary to use some tools, so prepare materials and tools in advance before installation, such as: steel plates, steel bars, copper plates, BV lines, etc., and the product quality must be qualified.

1. Installation requirements: When connecting the equipotential, it is necessary to carefully look at the welding part of each conductor, and there can be no undercut or porosity on the surface.

2. If it is an equipotential welded with iron, it should be noted that the length should not be less than 2 times of it, so special attention should be paid to this point during construction to avoid the impact of equipotential installation.

3. When the equipotential connection is carried out, sufficient contact area should be reserved at the conductor connection as far as possible, and the conductivity of the contact surface should be ensured.

4. If it is a connecting wire buried underground, the copper bare wire cannot be used, and the conductor of steel should be used, and the anti-corrosion treatment should be carried out. Generally, two times of anti-corrosion treatment should be done at the welding place, and the connection between the conductors cannot be crimped with bolts.

5. When the equipotential is connected to the terminal board, it must be kept firm, and the contact surface must not be corroded.

6. When the isotope is connected with other pipes, there are plastic connectors in the pipes, which can be crossed.

7. If the equipotential is installed locally in the bathroom, it should be noted that it cannot be connected to the external PE wire.

Summary: The above is about the role of the equipotential terminal box, I believe everyone understands! The lead equipotential of socks is an important part of building electrical appliances, which connects the protective trunks, heating and other parts of the building, and can play a protective role.

Grounding Equalization Boxes are electrical equipment used in restrooms to provide secure electrical grounding protection and equipotential connections. Its main function is to connect various metal devices (such as faucets, showers, toilets, etc.) in the toilet to the floor cover limb cord to ensure that the metal parts of these devices do not produce electric shock hazards during normal use.

An equipotential box causes them to electrically maintain the same potential (equipotential) by connecting the goldenrod parts of all metallic devices to a common grounding point. The purpose of this is to prevent potential differences between electrical devices and to avoid electric shocks when the human body touches different devices.

In addition, equipotential boxes can help protect electronic equipment in the restroom from electromagnetic interference, improving the stability and reliability of electrical equipment.
