Why do you need to be equipotential in the bathroom?

Many of you have heard about the news report of the electric shock that occurred when using the bathroom. In many cases, however, one of the causes of the danger caused by electric shock is that there is no equipotential device installed. Therefore, in order to ensure the safety of the human body, it is necessary to install equipotential devices in the bathroom.

1. Maybe most of my friends haven't heard of what this equipotential is, so let's introduce in detail the benefits and other effects of installing equipotential devices in the bathroom.

In fact, this so-called equipotential connection line is explained in the definition of the textbook, in fact, it is: all the metal objects in or near the building, such as the steel bars on the inner surface of the concrete, including water pipes, gas pipes, and other metal pipes, and then there are many basic metal objects on the machine, including the metal objects in its large buried ground, the most common cable metal shielding, the neutral line and scattered line of the power generation system, The grounding wires of many buildings are uniformly connected by the electrical connection method, which is commonly known as (welding or reliable conductive connection) so that the whole building can achieve a good equipotential system.

As usually, there will be no electrical appliances in the bathroom, but the risk of electric shock is also very high, because the hardware supplies at home are common, and the presence of steel bars in the cement slab on the wall will also have a certain amount of static electricity, when the static electricity accidentally accumulates to a certain extent, and we happen to use water in the bathroom, then it is very easy to cause the risk of electric shock! However, this is the same as the equipotential bonding terminal, that is, one end is connected to the ground, and the other end is connected to the hardware containing metal objects, if there is static electricity, it will be directly introduced to the bottom through the equipotential, so that the occurrence of electric shock can be completely avoided.

In our daily life, safety is always the first, and in indoor life, potential safety hazards are also essential, so in order to protect the personal safety of your family and yourself, please install water and electricity decoration reasonably, so that our indoor life can be safer and more comfortable!

Why should the bathroom be equipotentialAs for why the bathroom should be equipotential, from its most fundamental reason, it is to ensure the safety of electricity. From the actual situation to analyze, there are three main reasons: one is the specific characteristics of the bathroom, the second is the type of bathroom appliances, and the third is the habit of our household electricity.

I will answer this question from these three aspects.

Reason 1] The characteristics of the toilet are determined.

The so-called characteristics of the bathroom here refer to some of the routine use of the bathroom in our family, as well as some of the conditions of the original bathroom itself. And the combination of these situations shows the typical characteristics of the bathroom. It is mainly manifested in the following aspects.

1. The environment in the bathroom is a humid environment. This is due to the fact that the restroom is the place where we use the most water in our home. For example, when we take a shower, there will be a lot of water flowing to the floor, and then there may be water on the wall.

Therefore, for humid environments, the safety requirements for electricity are particularly high.

2. The size of the bathroom is relatively small. Like the bathroom in the building at the current stage, the conventional one is three or four square meters. Therefore, in this small space, it is possible for us to come into contact with any object, and it is inconvenient for us to escape and save ourselves.

3. There are a lot of conductive metal objects in the bathroom. For example, in the bathroom delivered by the rough house, there are common cast iron drainage pipes. And some of the metal objects we installed later will appear in the bathroom.

Handling suggestions: Therefore, for this very humid and narrow place, and there are many parts that can conduct electricity, our country has strict requirements in the electricity safety code. It is in these facilities and spaces that qualified and effective protective measures must be installed, especially local equipotentials.

Reason 2] The electrical characteristics of the bathroom are determined.

The characteristics of electrical appliances in the bathroom refer to some household appliances installed in our bathroom, which are generally used in a humid environment. For example, the most commonly used electric water heater in our bathroom, bath bomb, etc., will be damp and so on with the increase of time.

Issue. 1. With the increase of time, household appliances may have some problems in a humid environment, especially prone to leakage and short circuit of the circuit. Therefore, the requirements for the waterproof level of the electrical appliances in the bathroom are particularly high.

Issue. Second, after the installation of household appliances in the bathroom is completed, the distance between us and our body is very close. For example, the household electric water heater can be touched by reaching out, and when taking a shower, a certain leakage current can also be transmitted through the water.

These are all security risks.

Comprehensive analysis: For the household appliances used in our bathrooms, it is generally required to have a good and reliable grounding of their metal shells. At the same time, it is necessary to do a good job of its local equipotential connection according to the specification, and it is not allowed to be used without a ground wire.

Reason 3] Determined by the habit of household electricity use.

The habit of using electricity in the family refers to some habitual operations of electrical appliances that we usually use. Especially us.

Bathrooms do equipotential. This is to prevent electric shock in the event of a leak of electricity to the toilet.

The waterways in the bathroom are all connected to each other, and the function of equipotential is to fix one end of the wire on the metal outlet, and the other end is connected to the terminal block in the box. When bathing with water, if there is an emergency situation that causes the current to pass through the water outlet, the wire will decompose the current at the terminal at the first time, which is similar to the grounding wire, so that the electric shock accident can be well avoided.

Equipotential in the bathroom is because the hardware in the bathroom, as well as the presence of steel bars in the cement slab, will have a certain amount of static electricity, when the static electricity accidentally accumulates to a certain extent, and we use water in the bathroom, then it is easy to cause the risk of electric shock! The equipotential coupling terminal, that is, one end is connected to the ground, and the other end is connected to the shower and some hardware, if there is static electricity, it will be directly introduced to the bottom through it to avoid the occurrence of electric shock.

Because the bathroom is in contact with the water, the electrical appliances used are prone to conduction, and if the equipotential is made, there will be no current flowing inside the cavity area, so it also avoids the phenomenon of people planting electricity.

The main function of equipotential bonding: due to the humidity of the bathroom, it is easy to leak electricity. The function of the equipotential box makes the electrical devices and the grounding system in the toilet communicate with each other, reduce the potential difference, and ensure the safety of electricity.

The reason is that the human body is completely soaked during bathing, the impedance of the human body is large N1-drop, and the small voltage conducted along the metal pipes and metal components can cause electric shock accidents. This kind of electrical accident can not be installed leakage protector, isolation transformer and other protective electrical appliances to prevent, because this kind of voltage is conducted along the non-electric metal pipes, metal components, the only preventive measure is to make local equipotential bonding. The partial equipotential bonding in the bathroom is to connect the metal pipes and metal components in the bathroom at the equipotential bonding terminal board through the equipotential bonding line, so that the potential in the bathroom is at the same potential, even if this potential is higher than the ground potential, there will be no potential difference in this range, so as to avoid electric shock accidents.

After doing so, no matter the abnormal voltage from the **, due to the effect of equipotential bonding, the potential of all the conductive parts in the place will rise to the same potential level at the same time, and there will be no potential difference.

The toilet is a humid place, which is a frequent area for electric shock accidents, and motor accidents caused by electric potentials conducted from the outside of the toilet can only be prevented by implementing local equipotentials. Combined with engineering practice, 17 kinds of understandings and construction misunderstandings in building construction were analyzed.

Method steps.

The electrical appliances in the bathroom have been grounded through PE wires and are protected by leakage protectors, so the appliances do not need to be locally equipotential bonded. Local equipotential bonding and leakage protector are two different safety protection measures and cannot be substituted for each other.

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.

How to make up the equipotential in the bathroom.

The shell of the equipment is equipotentialally connected to the conductive metal, but I have a question, how to connect the equipotential to the steel bars in the wall and on the ground, and how to do it exactly? Welding equipotential wires to the rebar in the wall and on the ground?

Why is it necessary to make an equipotential connection with the PE wire of the socket when the toilet socket has a grounding wire? When there is no PE line in the bathroom, it is forbidden to connect with the PE from the outside world.

Just imagine, isn't the PE wire of the toilet socket also introduced from the outside world? Since the PE in the bathroom can be connected with equipotential, why can't it be connected to the outside PE (with the PE line in the living room).

How to make equipotential connection in swimming pools? Where do the equipotential wires be connected to the pool? Is it the steel bar in the pool?

In our daily life, in fact, many people themselves have a certain understanding of the decoration of their homes, and if there are certain problems in the layout of the home, then it will be very inconvenient to use.

Is it? On this issue, in my personal opinion, in fact, I think it is needed, and he can also facilitate our lives, so we will understand it in detail above.

1 I feel the need

The bathroom itself needs to be equipotential, and if there is no positioning, then we will feel very inconvenient to use, and now for most people, after we wash our hair, we generally need a hair dryer to blow the hair. And some girls are very easy to lose their hair in their daily life, if they go to other places to blow their hair, then it will lead to a lot of hair in the house, which is also very unhygienic, so I think if you make an electric potential in the bathroom, you can solve this problem very well, so I think it is very necessary.

2 Convenient for our lives

For everything in life, in fact, when we do it, we should carefully consider the consequences, that is to say, if there are some things in the home that are not of much use to our future life, we should try to think about it, but if it is good for us, we should take the initiative to do it. Because everything we do is actually done to make our lives easier.

Therefore, we should pay more attention to this aspect of the problem in our daily life, and it is beneficial for everyone to understand this aspect of the problem. Of course, when using electrical appliances at home, we must pay attention to some electrical safety issues. When there is any abnormal phenomenon, it should be reported to the police in time.

Yes, because it is also a particularly important renovation process, and in this way it protects the bathroom from electric shock.

Of course, it needs to be done, installing an equipotential can protect our safety, and when using electricity, we will be more assured that there will be no electric shock accidents.

It has to be done, and now many people will choose this decoration method, so I think it is still very useful.

Because this is more beautiful, and it can also be more convenient for later maintenance, and it can also fundamentally avoid the occurrence of electric shock accidents.

Because this is a thing that connects our electrical wiring, if there is this, our electricity will be relatively safe, avoiding electric shock and short circuit.

I think it needs to be made because that's the only way we can make it easier to use and more beneficial.

Equipotential is to achieve potential equality to ensure the leakage protection measures inside the bathroom; It can reduce the voltage difference to a certain extent, and can also eliminate some hazards caused by dangerous faults, and can also reduce the danger caused by unreliable electrical appliances, but it is particularly troublesome to install, and the life of electrical appliances is short, and it can only be started in the later stage of installation.

Equipotential is in a live line, if two test points are selected to measure, there is no voltage between them and there is no potential difference, then it is determined that these two test points are equal potential, and there is no resistance between them; The advantage is that it can prevent electricity leakage in the bathroom, and the disadvantage is that it will be more difficult to repair and overhaul in the future.
