What to do with the equipotential coupling end in the bathroom

Is it necessary to connect the equipotential bonding end with the grounding wire of the suit in the switch box?

The equipotential bonding end is connected to the grounding wire of the color in the switch box--- it is possible to do this, and it is okay not to do it. One is the grounding of the metal shell of the building and sanitary equipment, and the other is the grounding of the electrical shell.

In the process of continuous development and updating of electrical safety technology, a large number of electrical accidents are caused by excessive potential differences. In order to prevent all kinds of electrical accidents caused by excessive potential difference, the 20th equipotential connection, the international attaches great importance to the role of equipotential connection, which is very necessary for electrical safety (personal safety), lightning protection and the normal operation and safe use of electronic information equipment. According to theoretical analysis, the smaller the range of the equipotential bond, the more electrically safe.

As; The specific construction of the computer room: the metal components used in the decoration of the computer room are connected with plastic copper wires and connected to the equipotential grounding box. Since the 60th of the century, the application of equipotential bonding safety technology has been promoted internationally, and equipotential bonding has basically been used in new buildings.

There is an equipotential junction in the bathroom of the new house, which is also marked as immovable. The specific meaning of this sentence: the metal shell of the water appliances in the bathroom must be connected to the equipotential box with wires.

As you said: now it's all PPR water pipes, so you don't need to connect them.

A 40x4mm hot-dip leaded flat steel is welded from the steel bar inside the beam, and a potential bonding iron box is concealed 30mm from the above level, which is connected with the flat steel that is drawn out, and then a line is reversed, and it is connected to the distribution box as a special PE line for the room.

The PPR pipe does not conduct electricity, but the water in the pipe conducts electricity! Be sure to pick it up.

1. The equipotential connection standard requires that all metal parts of the bathroom must be connected with the equipotential connection box, and it must be a new connection method, which must be connected with the equipotential box separately using a flexible wire of 6 square millimeters. If the grounding wire of the electrical system is also introduced in the bathroom, the grounding wire must also be connected to the equipotential box.

2. If there is a socket reserved in the sanitary sail room, and there is a grounding wire (yellow and green two-color wire) in the socket, the grounding wire must be connected with the hail equipotential box of the pants. If there is only a phase wire (live wire) and change in the pure macro of the socket, then of course there is no wire and equipotential box to connect, but it must be remembered that you cannot use electrical appliances with grounded shells in the bathroom, only double-layer insulated appliances, that is, electrical appliances with a return logo on the electrical shell.

Because the toilet uses water more frequently and is a humid place, if the electricity is not used correctly, it may lead to electric shock accidents, so special attention should be paid when installing wires, and it is necessary to prevent it with the help of local equipotential. So how do you connect the equipotential in the bathroom? What problems should I pay attention to when wiring?

Let's find out.

First, how to connect the potential of the front grinder and bathroom.

First of all, it is necessary to weld the rebar connected to the main column welding with galvanized flat iron and steel bars, and install an equipotential special iron box in the bathroom wall (generally sold in bathroom stores). If the toilet socket has a grounding wire, the reason for equipotential connection with the PE wire of the socket is that it can block the distance, the resistance value is small, and the safety factor is relatively high.

2. Precautions for potential connection of toilet wisdom bending bucket.

Generally, the equipotential is installed under the washbasin, and the grounding work should be repeated between the branch sockets. If the bathroom has dry and wet separation, it is recommended to install equipotential in the ceiling. Because the ground is relatively humid and it is connected with the equipotential, there are still certain safety hazards.

The flat steel of the local equipotential box should be welded and introduced according to the node of the bottom plate reinforcement, and the column reinforcement and shear wall reinforcement within the local range should be welded and connected.

The main reason for doing equipotential is that the number of cable cores is insufficient, and it is necessary to add PE wire when making the cable head on one side and connect it to the PE row of the distribution box. As long as there is a socket inside, the PE wire in the socket can be connected to the row, and the pipe is concealed and connected with soft copper wire.

Many people ignore the equipotential, in fact, the equipotential is closely related to the safety of electricity, if the equipotential is not installed, it is very likely to have a leakage accident when taking a bath, the body surface resistance is too low, and the leakage protection action has been uncontrollable. Therefore, when we install the plug-in round seat, we must strictly follow the specification atlas to wiring.

Conclusion: The relevant knowledge about isopotential will be introduced to you here, I hope it will be helpful to you. If you want to know more about related knowledge, please continue to pay attention to the Qeeka Home information platform, and more exciting content will be presented to you in the future.

<> first of all, all the metal parts of the toilet are linked to the equipotential connection box, and it is worth noting that the 6 mm cord must be connected to the equipotential box separately. In addition, equipotential installation requires a professional master to carry out the construction to ensure safety. Among them, the construction standards for equipotential installation are as follows:

1. Installation requirements: pay attention to the welding parts between the conductors to ensure that the welding is accurate and tidy. Second, there should also be contact surfaces between various metal conductors to ensure connectivity.

3. The connecting wire buried under the bottom should be made of steel conductor and subjected to corresponding anti-corrosion treatment. Fourth, if there is plastic when the auxiliary equipotential box is connected to the tube, it is recommended to do leaping treatment.

When it comes to equipotential, many people may know a little bit about it, but it is a device that can protect your life and age. So the question is, do you know how to connect the equipotential in the bathroom? What is the construction standard for equipotential installation?

Don't worry, if you're interested, let me take a look.

In the process of equipotential connection in the bathroom, the metal water supply and drainage pipe, the metal bathtub, the metal heating pipe and the ground reinforcement mesh should be connected to the equipotential terminal board through the circuit, and when the wall is a mixed earth wall, the reinforcement mesh in the wall also needs to be communicated with the equipotential connection line. In addition, it is recommended to decide whether to do equipotential or not for items such as metal floor drains, handrails, bath towel racks, and soap dispensers on a case-by-case basis. I would like to remind you that:

Equipotential installation and construction are relatively professional and require professional master construction.

Equipotential installation construction standards.

1.Material requirements: There are many materials used, such as: steel plates, steel bars, copper plates and BV wires, etc., the premise is that these products must meet the requirements.

2.Installation requirements: When equipotential connection, special attention needs to be paid to the welding parts between the conductors, and there can be no slag inclusion, undercut or lack of welding.

3.In addition, it is also necessary to pay attention to the welding of iron strips, and the length is not less than twice the width of the iron on three sides.

4.In the case of equipotential connection, the contact surface of each metal conductor connection should be left and the conductivity of the contact surface should be ensured.

6.When equipotential connection terminal plates, it is necessary not only to tighten them, but also to ensure that the contact surface is not corroded.

7.When the auxiliary equipotential box is connected to the tube, if there are plastic connectors in the tube, it is recommended to do jumper treatment.

8.Here we also need to remind everyone: the equipotential connection of the bathroom should not be connected with the PE wire outside the bathroom.

Summary: After reading the above introduction, I believe you have a further understanding of how to connect the equipotential in the bathroom and the construction standards for equipotential installation. If you want to know more about it, please continue to ******, and we will present you with more wonderful internal codes in the future.

A 40*4 galvanized flat iron is used to connect to the steel mesh on the bathroom floor, and the galvanized flat iron is reserved upwards at the position of the bathroom wall, and the distance from the ground is about 50cm.

The following conductive parts are connected to each other through the total equipotential bonding bus bar near each incoming distribution box: the PE (Pen) bus bar of the incoming distribution box, the metal pipes such as water and sewer, heat, and gas of public facilities, the metal structure of the building and the grounding lead wire. Its function is to reduce the indirect contact voltage and the potential difference between different metal parts in the building, and to eliminate the danger of dangerous bright block fault voltages introduced from the electrical wiring and various metal pipes outside the building.

Of course it works. There are many cases of electric shock when there is no equipotential installation in the shower, and there is no equipotential in the bathroom of the old house.

Equipotential is to reduce the contact voltage of indirect contact shock in the building and the potential difference between different metal parts, and remove the danger of dangerous fault voltage introduced from various metal pipes of electrical circuits outside the building.

According to the standard of the People's Republic of China "Residential Design Code GB 50096-2011", "Requirements for Special Devices or Places: Places Equipped with Bathtubs or Forest Bathtubs Tan or Chun GB 16895 13-2002", residential toilets with collapsed shower equipment are listed as high-risk electric shock places in residential buildings, and the Notice of China Building Decoration Association on Prohibiting the Removal and Permanent Closure of Local Equipotential Devices in Residential Bathrooms in Residential Decoration and Decoration Construction also clearly pointed out, " Equipotential connection and installation of the Department of Health" as a mandatory standard.

For residential construction projects delivered after 2005, equipotential devices are reserved for bathrooms, which need to be connected during decoration and construction design, so as to effectively play the protective role of "lightning protection, anti-static, and anti-leakage".

To prevent electrical fires and leakage fires, install Huatian Century Electric Fire Monitoring System.

The practice of equipotential bonding in the bathroom requires that the metal components that may be touched by hand: heating pipes, water pipes, sewer pipes, and foundation steel bars are connected together, and then connected to the terminal box of equipotential bonding.

Because there is moisture in the bathroom, it is recommended to place this box on a suspended ceiling or in a dry and easily accessible location.

If the bathroom is small, I recommend that there is no need for equipotential coupling. As long as the grounding of the electrical equipment (electric water heater) in the bathroom is good enough, it can be guaranteed that there will be no electric shock problem.

In fact, the equipotential bonding technology makes sense in theory, but the technology realized in practical engineering is not perfect. You can consider it appropriately in your own home.

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.

In the bathroom, all kinds of metal pipes, structural parts (including steel bars in the concrete floor slab) and the line of sight into the toilet are connected with a copper core wire of not less than 4mm2 through the equipotential bonding terminal box The equipotential bonding wire should be protected by a plastic pipe when it is concealed on the floor or wall, and its purpose is to replace the wire conveniently. The resistance between a metal body such as a metal pipe within the equipotential bonding range and the terminal strip in the equipotential bonding box should not be greater than 5. The connection of the metal pipe in the bathroom generally does not need to be jumped, and if it is found that the conduction is poor, it should be crossed.

When the water pipe in the bathroom is a plastic pipe or a plastic-coated metal pipe, the equipotential jumper wire can be connected to the faucet; When metal water pipes are used, jumper wires are connected directly to the water pipes. The sewage pipe in the toilet is not connected to the water inlet pipe, so the sewage pipe should also be equipotential connected and can be connected to the pipe of the floor drain.

Equipotential is to make the leakage potential of different electrical equipment the same to avoid the potential difference to the human body of electric shock.

This is not harmful to people, and it is generally done on the wall and does not affect the waterproofing of the bathroom.

It can't be pasted, and the equipotential connection terminal box is not electrified, and it is generally useless, but it is not possible to accept it.

He should be connected with the metal pipes, brackets, metal appliances and so on in the building, the function is to make each floor in the building at the same potential without potential difference, to protect personal safety, and the box is connected with the foundation lightning protection net (i.e. the foundation steel bar).
