How To Ground A Washing Machine In A Bathroom

Do I need to ground my washing machine for safety

Many people ask whether it is necessary to ground the washing machine if, for example, the floor in the room is insulated with linoleum or other materials that are insulating. But, many people forget that, for example, water can accumulate on the floor in the bathroom, which is an excellent conductor of electric current. If the washing machine is not grounded, the accumulated voltage on the body can hit a person through the accumulated water.

It is imperative to ground the washing machine, as this will allow, in the event of a phase hitting the machine body for various reasons, to prevent electric shock.

Also, grounding allows you to reduce the potential difference between the neutral wire and the floor or the bathroom and water pipes. The potential difference is expressed in a tingling current if you touch a running washing machine and, for example, a bath. So, the answer to the above question will be an unambiguous answer. the washing machine must be grounded.

How To Ground A Washing Machine In A Bathroom

The main thing is to do everything right:

  • Connect ground using a dedicated socket.
  • Also, connection to ground is possible using a single-core wire that is taken out of the apartment and grounded to a special bus located on the dashboard.
  • If there is no bus, then you can bring the wire out of the apartment and ground it to a metal pipe dug into the ground.

Some “craftsmen” make grounding on heating pipes or water pipes, but this is wrong, since, if a phase hits the body of the machine, the current will go through the pipes, which is fraught with damage to other people. In parallel with grounding, it is recommended to install an automatic shutdown device for the supply of current to household appliances.

Recommendations: how to ground a washing machine, steps

Not only old models of washing machines can shock you, but also new modern options. This is especially true for washing machines that are installed in bathrooms. Voltage up to 110 volts can be generated on the case of ungrounded washing machines, which is fraught with electric shocks, and this can lead to sad consequences. Grounding will reduce the likelihood of electric shock to a minimum.

The socket to be installed must also be with a grounding contact and must be waterproof.

It is quite simple to ground the washing machine, for this you should do the following. in old houses there is usually no third contact in the outlets, which is grounding, in this case, you can fix a single-core copper wire in insulation with one end on the machine body, and bring the other end to the electrical panel to common ground loop. In low-rise buildings, the ground wire can be brought out to the street and fixed on some metal object, which should be deepened into the ground.

It is best to lay a separate line for the washing machine, consisting of a three-core wire:

  • One wire is a phase;
  • The second will be zero;
  • And the third will be grounding.

Some people, in addition to grounding, also install an automatic power cut-off device, which further increases the safety when working with household appliances. All electrical work is best entrusted to a professional.

Do-it-yourself grounding methods for a washing machine

Grounding the washing machine allows you to prevent not only electric shock, but also to extend the life of this household appliance. Traditionally, in most houses, the wiring is done with 2 wires. zero and phase. If the washing machine or other equipment, for example, a dishwasher, is plugged into a regular outlet without grounding, then in this case, voltage may accumulate on the equipment case, which is fraught with not light electric shocks.

If the wires are damaged inside the machine, higher voltage may build up on the case.

That is why it is imperative to mount the grounding of household appliances, and those who live in a private house can do it with their own hands. A single-core copper wire in insulation is attached to the washing machine, which is laid first through the apartment, and then taken out into the street and fixed on the central pipe. The pipes are connected to each other using a metal plate or fittings, by welding.

For grounding you need:

  • Take 3 metal pipes about 2 m long;
  • They need to be buried in the ground so that no more than 0.5 m remains above the soil surface;
  • The distance between the pipes should be about 1 m.

Thus, you can easily do the grounding of a washing machine in a private house with your own hands. If it is required to ground other household appliances, then in this case it is necessary to install a grounding bus on the shield, connect a grounding wire to it, and then connect other household appliances to this bus as well.

Washing machine without grounding: is it permissible

Some people, when buying a washing machine and other household appliances, neglect grounding, but this is quite dangerous, since in case of any problems with the wiring, the equipment can fail. But the most dangerous thing is that without grounding, household appliances, including a washing machine, can shock a person, and this can be not only unpleasant sensations, but even deaths. When planning grounding, as well as when installing an additional RCD, it is recommended to lay an additional line from the shield to the washing machine. This will prevent accidental operation of the RCD, as well as ensure reliable grounding of equipment.

The operation of the washing machine, especially in a damp room, for example, in a bathroom, without grounding at all is not allowed according to safety regulations.

Correctly performed grounding will ensure not only the stable operation of the equipment, but also prevent an accident. Some people connect the machine to the network, and after some time of operation, seeing that nothing terrible is happening, they stop paying attention to how the washing machine is connected. But in the event, for example, of an increase in voltage as a result of a break in the neutral wire, it can accumulate on the machine body, which is fraught with an electric shock, as well as failure of the machine electronics.

Tip: how to ground a washing machine if there is no ground

If you correctly carry out all the connection of the washing machine, then its operation will be completely safe, and not only for humans, but also for the electronics inside the equipment. Basically, the same goes for almost any household appliance.

How to ground a washing machine if there is no grounding: in an apartment with your own hands, is it necessary in a bathroom, how is it correct

You can ground the washing machine yourself, if you approach this process correctly.Most household washing machines are installed by their owners on their own without taking into account safety requirements. To ensure safety and to prevent electric shock, you must ensure that the washing machine is grounded. This is especially true for machines installed in bathrooms.

Does the laundry smell like damp after washing? It’s time to clean the equipment. How to clean a washing machine at home from dirt, unexpected.

In the post-Soviet space, automatic washing machines appeared more than two decades ago. They cost a lot, so the greatest.

There is only one effective recipe for success: doing what you love, investing maximum time and effort into it. At the same time, you need to be in shape: good.

Option two: grounding in the bathroom

How to install grounding on a washing machine in a bathroom if there are no special contacts on the shield? Use the potential equalization method. The fact is that there are a lot of objects in the bathroom that conduct electric current. You don’t have to touch the washing machine body to get a small electric shock. you just need to touch the mixer. We propose to connect all objects that conduct current with metal wires. thus equalizing the potential.

When placing the Washing machine in the bathroom, it is imperative to install waterproof outlets.

However, this is not enough. For a washing machine without grounding, an RCD is additionally installed. An automatic shield is also required. In case of failures and overloads, the shield will simply knock out, which will save your equipment from damage. Of course, Bosch was not without home craftsmen who came up with their own way of leveling. It is much cheaper, just as effective, but against safety measures and has its drawbacks. In this case, the ground wire of the washing machine is fixed to a metal pipe or battery.

Quite a dubious option, since pipes quickly collapse under the influence of electricity. This will incur additional costs for their replacement.

Many people doubt: is it possible to zero the washing machine? This question is relevant when there is no ground wire on the shield. In this case, there is an option to connect the wire to the zero phase. However, this method is not safe. You decide which option to use in the apartment. One thing is for sure. a washing machine without grounding will sooner or later cause unpleasant situations.

Why you need to ground your washing machine

After buying a washing machine, many users boldly connect it to the nearest outlet and do not even think if this is correct. First of all, you need to ground the washing machine for your safety.

Think about it! Even cars with an EMC filter installed are capable of passing 110 volts through the chassis. And if the filter burns out or the wiring is broken, the electric shock can be 220 volts. This is a direct threat to your health and, if installed in a humid environment, to life.

over, if there is no grounding, the equipment itself can deteriorate. Contact of water with damaged wiring will lead to a short circuit and complete combustion of the washing machine. Consider which is more profitable: learning how to properly ground your washing machine or buying new appliances. Let’s figure out the features of the do-it-yourself grounding installation.

How to ground a washing machine

When purchasing household appliances, the user is obliged to take care of its safe connection in order to protect himself from electric shock, and household appliances from damage. The washing machine is often installed in the bathroom, where the risk of electric shock increases several times. How can I avoid this? Need to ground the washing machine.

Grounding the washing machine in the apartment

The apartment has two grounding options. One of them is correct and legal. Another is also often used by the common people, but is ineffective and “outlawed” today. We will tell you about each of them so that you have an idea of ​​the pros and cons of these methods. What tools will be needed:

  • Pliers;
  • indicator screwdriver;
  • tool to strip contacts.

Attention! Unplug the machine before starting work.

First option: grounding in old houses

This method will tell you how to ground the outlet and the washing machine in the apartment, if there is no grounding initially. Let’s make a reservation right away that this option is suitable for residents of old buildings, since all sockets in new buildings are equipped according to modern standards. Progress:

  • It is necessary to organize the wiring that will go to all household appliances, including lighting in the apartment.
  • To do this, two buses must be installed in the electrical panel, to which the wiring will be connected in the future. The buses are designated as zero. N, and with grounding. PE. How to connect grounding to the shield, read on.
  • A wire is routed from the outlet to which the Washing machine is connected. It should consist of three cores with a copper section. Connection is carried out as shown in the photo below.

First, connect the blue neutral wire that goes to the N bus. Then connect the ground wire to the PE bus, in different cases it can be green or yellow. Now the red phase wire is connected to the RCD of the meter.

Note! It is forbidden to swap contacts.

Thus, you can protect yourself and your equipment. If you are afraid to carry out such work, then call an electrician.

Grounding a car in a private house

If it is important for you to know how to ground a washing machine in a private house, then you can do this in the same way as in an apartment. follow the above methods. However, there is another option. Residents of the private sector can independently organize grounding on the street. To do this, select a free area in the yard. It will take three metal pipes. Usually, pipes from old beds, at least 1.5 meters long, are used for these purposes. Next, do this:

  • Install the pipes in the ground, at least 2 meters deep. The distance between them should be from one to one and a half meters.
  • The installation is done so that 15 centimeters of the pipe remain sticking out above the ground. Metal plates are welded to them.
  • A ground wire is connected to this structure, which is welded to one of the plates.
  • The other end of the wire is fed to the switchboard and connected to the PE bus (ground).

If your washer has a special bolt, you can lead the wire to it, and not to the shield. There are times when the machine is shocked due to a breakdown. Therefore, before starting work, inspect the washing machine at the time of damage to the wiring. After all, if you do not replace the damaged area, there is simply no point in carrying out the work. Grounding in any room should be provided with three-core wires. They should be carried out from the shield to all sockets. The remaining options, although effective, are hazARDOus to health. If you are not familiar with electrics, it is better to call a specialist at home. For those who decided to work on their own, on the topic:

Grounding conductor color

In order to ground the washing machine without errors, it is worth knowing the requirements for the colors of the grounding conductors. On sale you can find wires of various options, which is made for convenience and safety.

When arranging wiring, the following wires are usually used:

  • Red. phase;
  • Blue. “zero”;
  • Yellow-green. “earth”.

In practice, colorless or white conductors are used. In the latter case, the ground wire is in the central part.

With this approach, it is difficult to make a mistake, because when connecting, you need to connect the wires taking into account the color. red to red, blue to blue. As for the yellow-green “ground” wire, it must be “put” on the grounding terminal.

In a private house

Connecting the grounding of a washing machine in a private house differs little from the aLGorithm discussed above. The ground wire is also led from the main panel.

The difference is that there is no grounding in the entrance, and you will have to do it yourself. Previously, the installation process was briefly considered, but we give detailed instructions:

  • Find three pipes made of metal that are one and a half to three meters long. When choosing a length, keep in mind that it should not be less than the depth to which the ground freezes in winter.
  • From the bottom of the pipe, use a sledgehammer to sharpen it and here drill holes 0.5-1 cm.
  • Dig a hole 50-60 cm deep, then drive the pipes into the ground at a distance of one to one and a half meters. There should be 100-150 mm of pipe above the surface.
  • Find three metal plates (you can use reinforcement) 100-150 cm long, and then weld them to the edges of the pipes that are above the surface.
  • Weld the ground wire to the armature, which will go to the meter installation site. Laying method is selected according to local conditions.
  • Connect the grounding wire to the PE bus, and then branch the grounding wires to lighting and sockets.

For reliability, the ground wire is bolted to the back of the machine (such a bolt is already provided by the manufacturer).

What to consider?

When grounding a washing machine in a bathroom, in a private house, in the country, in a Khrushchev or other place, consider the following:

  • It is forbidden to use water pipes as “earth”. The reason for this requirement is discussed above. It is worth adding that many people replace metal pipes with plastic structures, so metal pipes in your apartment (house) will be separated from the “ground”. Incorrect connection with violation of PUE and PTE often leads to accidents.
  • It is forbidden to use heating pipes (the reasons are the same).
  • If neutral conductors are connected, it is recommended to ground again.
  • The socket must not only be grounded, but also withstand current up to 16A.

We ground the washing machine in the apartment

The method of connecting a washing machine in an apartment of a multi-storey building depends on the year of construction of the object. If the house is newly built and belongs to the category of new buildings, it will not be a problem to find a grounded bar in the shield.

over, many houses are built taking into account the plant “land” in each apartment, and the wires are laid with three conductors.

READ  Which Difavtomat To Put On The Washing Machine

Household appliances (washing machine, microwave oven and other equipment) have a three-core wire, so safety is guaranteed.

If the building was erected before 1990, you should carefully examine the shield for the presence of a grounding bus.

There are two ways to ground the washing machine. do it yourself or use the services of an electrician.

When connecting independently, the aLGorithm of actions is as follows:

  • Install two buses in the shield. zero and ground. Wires will be connected to them, which will go to the apartment to lighting devices and household appliances.
  • Stretch a cable with three copper conductors with a cross-section of 2.5 square meters from the driveway to the washing machine. mm. The wire is connected as follows. First, the blue wire (“zero”) is connected to the N scale, and then the red wire (phase) passes through the circuit breaker, RCD and goes to the electricity meter. Ground (blue-yellow wire) must be connected to the ground bus. It is forbidden to combine grounding and working zero.

Next, it remains to put the socket and connect it. This requires a socket, an indicator screwdriver, pliers, a three-core cable, a knife and a socket with a grounding terminal. If the considered complex of works seems complicated, you should entrust the work to the master.

Why ground a washing machine, what are the risks?

At first, there is a slight tingling when you touch the typewriter, and after a while (if nothing is done). a strong discharge.

Electricians assure that all electrical appliances are to be grounded. To a greater extent, this applies to devices that are used in the bathroom due to the high level of humidity. There are many outlets and appliances in this room, which creates potential risks for residents.

Grounding is required for two reasons:

  • If the equipment is not grounded, voltage may appear on the metal parts of the washing machine and the person will be exposed to 110 volts. Despite its small size, this potential is enough to kill.
  • Many models of washing machines that operate without grounding fail faster.

The presence of a ground connection guarantees safety for the user. When the insulation deteriorates and the wire breaks down in the supply circuit (inside the washing machine), the voltage falls on the grounded circuit. As a result, a short-circuit current flows in the network and the input circuit breaker turns off the power.

In the absence of grounding and a person getting under voltage, the machine may not work. As a result, a dangerous current flows through the body.

Grounding methods

Let’s highlight the main options for how to ground a washing machine in a bathroom or other room.

  • Connecting the case to the sewer, water supply or batteries.
  • Personal socket outlet for which the ground wire is connected from the driveway.
  • Creation of a system that equalizes the potentials of equipment in an apartment.
  • Switching on at the RCD input.
  • Making your own ground loop. The latter option is suitable for cases when a person lives in a private house.

Many people make a mistake and choose the first option. In theory, he is a worker, but his own salvation can end with the following consequences:

  • With a breakdown to the case and poor grounding of the elements, the potential turns out to be on the water supply system or battery. As a result, people (residents of other apartments) may suffer, who at this moment touch the metal part.
  • This method of grounding accelerates the destruction of the metal. As a result, the pipe is damaged faster and there is a high risk of flooding for neighbors and your apartment.

In addition, PUE and PTE prohibit this method of grounding, so it should be abandoned.

The best way is to plug in a separate outlet that has a grounded wire from the driveway. The option is suitable for cases when a grounding loop is provided in the house (in some multi-storey buildings of the old building it is not).

The difficulty is not to confuse working zero and “ground”. If you make a mistake and put the wire in phase, a short-circuit current will flow in the circuit. The result is a disconnection of the supply machine at the entrance (for one phase). In addition, there is a high risk of burns.

Another way is to connect an additional wire to a metal grounded bus, which is grounded and runs through all floors, and then “tightly” connect the wire to the body of the washing machine.

The disadvantage of this option is that you will have to violate the integrity of the equipment casing, and the appearance of household appliances deteriorates.

The solution with the equation of potentials implies the following actions. The cases of metal devices in the apartment (house) are interconnected by current-carrying elements (wires). There is a uniform potential distribution.

If the phase hits the ground, the potential will pass along the path of minimum resistance, and will not go through the human body. There is nothing complicated in the implementation of the scheme, so it is easy to do it yourself.

If in a private house or apartment there is no grounding and a conductor with two cores is laid, it is worth choosing an alternative option. to put an RCD or a difavtomat at the entrance to the apartment.

These devices react to leakage currents and cut off the power. Installing devices has already helped save thousands of lives from electric shock.

The operation of the device is based on a comparison of the input and output current. When the parameter is changed above the set value, the device is triggered.

But it is worth considering that in old apartments where the wiring has not changed for a long time, a large leak and false triggering of the RCD is possible. To avoid this, it is worth replacing or revising (replacing) the wiring. Today, the option with an RCD is most in demand due to its ease of installation, reliability and compliance with safety requirements.

If the goal is to ground the washing machine, other equipment and the house itself, you need to make a separate circuit with the subsequent connection of a conductor to it and supply to the shield.

To create a contour, you need to dig a ditch in the shape of a triangle with equal sides, having a length of 3 meters and a depth of 50 cm or more. When preparing the pit, keep in mind that one sharp corner should “look” at the house.

At the vertices of the triangle, pins made of metal from 3 meters long are hammered, after which they are scalded by welding using a metal strip. The outline is ready.

Next, a ditch is dug under the cable, which is connected to a new circuit and is brought to the common shield of the house. From above, the structure is covered with earth.

If you have a megohmmeter, it is worth checking that the resistance of the structure does not exceed 4 ohms. If this is not possible, you can call the isolation service personnel to check this parameter.

How to ground a washing machine

When buying and installing a washing machine, few of the owners think about safety. The person removes the shipping bolts, connects the hoses, and plugs the equipment into a non-grounded outlet. This approach is dangerous.

Connecting without ground will negatively affect the life of the equipment and the safety of the people who use it.

What are the features of installing a washing machine in a bathroom, in a private house, in the country or in a Khrushchev? How to properly connect household appliances with your own hands? How to get out of a situation when grounding is not provided in the house? We will consider these and other questions below.

How to ground a washing machine in Khrushchev. a house where there is no grounding?

In houses of an old building, grounding may not be at all. precisely, there is no grounding bus in the driveway. There is also no way to find “land” when living on the fifth floor.

In such a situation, it is worth protecting against voltage breakdown on the casing of the washing machine by equalizing the potentials. The principle is as follows.

If household appliances are in the bathroom, in the case of simultaneous contact of 2 conductive objects, the current will go through the human body.

The essence of potential equalization is that metal cases are combined with each other. As a result, if you touch a tap or a washing machine, the current will not go through a person.

To reduce the level of risk, it is worth installing an RCD and a circuit breaker at the entrance to the apartment. In this case, in case of insulation breakdown, a short circuit will occur, and the machine will turn off the power.

In addition, the bathroom should be equipped with a high-moisture protection socket. If there is none, you should choose a different place for the washing machine.

When installing electrical wiring, it is worth using solid wires. If docking is required, installation takes place in a box, and bare wires are carefully insulated.

To simplify the task of grounding, many lead a wire from the body bolt to a sewer pipe or heating battery. Doing this is prohibited for the reasons discussed above.

Grounding your washing machine is an important step in installing these household appliances. Without such work, the service life of the equipment is reduced, and there is also a risk of falling under the stress of relatives and friends.

Spending several hours of time and a couple of thousand rubles, you will eliminate risks and ensure long-term operation of the equipment.

Panel connection

If the house is not grounded, it can be simulated using a neutral wire. This method is used quite often, and has already justified reliability and safety. The zero wire must be bifurcated, and the exhaust bus must be fixed on it. The bus is also fixed to the ground. The cable routing to the apartment is deduced from these buses.

To connect the equipment, you need to install a new outlet, which will be powered directly from the switchboard using a three-core cable. The cores are connected to certain contacts according to the scheme. To connect the cable to the shield, AZO and 2 buses are used.

If you connect zero directly to the ground contact in the shield, there is a chance of damage to the wires, which will bring very unpleasant consequences. Also, the effectiveness of such grounding is much less.

Reference! To ground the washing machine through the shield, you only need an indicator screwdriver, pliers and a wire stripper.

Many people turn to electricians to solve this issue. However, those who are familiar with the wiring system in the house, and skillfully wield the tool, can connect the washing machine to the ground on their own.

Grounding to the battery in the bathroom or sewer pipe

A long time ago, some craftsmen came up with a method of grounding, which uses metal pipes for heating and sewage.

The cable was connected to the battery using special connections. For a long time, the method was the most widespread due to its high efficiency. However, grounding to a battery has several disadvantages:

  • Unlawfulness. In the GOSTs of behavior with electrical wiring, it is indicated that such actions are dangerous, therefore it is strictly forbidden to use the method. But the law is not terrible for the common people;
  • Harm to elements of the heating system. Electric current promotes corrosion of metals, therefore, leaks often form at the joints of pipes (batteries) and cables;
  • Insecurity. This grounding circuit does not completely eliminate the chance of electric shock.

The method is simple to implement, so many still choose it. This requires a copper wire with 1 core. Remove the insulation at both ends. One end is fixed to the body of the equipment, the other to the water supply. You can fix the wire using a metal clamp.

Important! Grounding to the heating system will sooner or later provoke a breakthrough of pipes or radiators.

How to ground a washing machine

Today, large household appliances, like a washing machine, are designed for a single-phase, three-wire AC system. Connection is carried out in phase, zero and ground. Old apartment buildings and private houses are often connected to a two-wire current system, without using a ground wire.

To keep family members and electronics in your home safe, be sure to ground your washing machine. The technology of the process depends on the type of structure, and the presence of a connected grounding to the switchboard. If the cable is connected, the procedure will not take long, and everyone can cope with the task.

Grounding methods

Grounding is a conductor that is driven into the ground. There are 2 types of grounding for the purpose of operation:

  • Working. Protects electrical equipment from damage;
  • Protective. Designed to protect people from current.

Modern houses are precisely equipped with a three-wire network, so connecting the machine to the mains will not present difficulties. A cable is taken out of the apartment from the outlet, which is connected to it by 3 wires. If the ground is not connected to the apartment building, the potential equalization method can be applied. But this method is not completely safe.

The “grandfather” method can be called the fixing of the ground wire from the machine to the heating radiator or pipeline. The method has not been used for a long time, since it is far from safe.

Residents of private houses can fully conduct the grounding system. To do this, it is necessary to create a chain of metal pins, which are buried in the ground to a depth of 1.5 m. By welding, the wire is connected to a metal circuit, which will allow current to be output to the ground.

How to ground a washing machine if there is no ground?

With the purchase of a washing machine, the question of additional security arises. If the electrical appliance is not properly connected, electricity will pass through the metal body of the machine and there is a chance of getting an electric shock.

Also, incorrect connection can damage the electronics of the machine. Parts have a considerable cost, and repairs are not always easy.

Washing machines are often equipped with a mains regulator that blocks power surges. It is connected directly to the vehicle body. If there is no ground in the outlet, then such a stabilizer generates a voltage of 110V on the metal parts of the case.

Important! Washing machines are mainly installed in the bathroom. The percentage of moisture in it is always high, so the chance of getting an electric shock increases.

Grounding. private house

Residents of a private house, in addition to connecting the ground to the shield, need to design the system itself. The process consists of the following steps:

  • 3 pipes are selected, the length of which depends on the level of soil freezing. For a temperate climate, this is usually 1.5-3 m.
  • One side of each pipe is sharpened.
  • From below, about a third of the length, holes are made in the pipes up to 1 cm in diameter.
  • A hole is dug up to a depth of 50 cm.
  • The pipes are driven into the ground with a sledgehammer. The distance between the elements is up to 1.5 m.Pipes should protrude from 10 to 15 cm above the ground.
  • Three pipes are connected with fittings. A triangle is formed, which is fixed by welding.
  • The grounding cable is connected to the armature by welding. Into the house.
  • The wire is connected to the PE bus, which allows the whole house to be grounded.

Most models of washing machines have a special bolt at the back for connecting a ground to it. It ensures the reliability and security of the system.

Through the electrical panel

It is better to ground washing equipment through a stationary electrical panel. it is effective and civilized. To do this, you need to install a separate socket of a special shape for the machine, and the three-core wire will go to the shield, where it will be connected to ground.

To complete the work, you need to prepare a simple set of tools:

  • probe with indicator;
  • pliers with insulators on the handles;
  • a special tool for stripping the ends of wires or a sharp knife;
  • duct tape and stock of enthusiasm.

All conductors need to be connected only to the appropriate place. two buses and a special switch that works in automatic mode.

The safety precautions for electrical work are written on the basis of real cases, sometimes with a fatal outcome, so you should not neglect it.

Grounding is not considered a difficult task, but if you are unfamiliar with the basics of electrical appliances and similar networks, then it is better to seek the help of a professional electrician. Financial costs will be small, but the guarantee of safe use of household appliances is 100%.

When working independently, you need to know:

  • On any standard electrical panel there are two buses. zero (N) and grounding (PE), only from them do the wiring.
  • Having made the necessary wiring, you need to connect the wire in this way: connect the blue to the N bus, red through the RCD with the meter phase, and the yellow-green color to the PE bus.

Remember that this method of grounding is made legally and is extremely reliable.

Recall the theory

Many users do not even think about such a problem as grounding and calmly operate the equipment for many years, not suspecting that they are exposing their loved ones to the danger of electric shock. Only after receiving a tangible blow, touching simultaneously the body of the machine and the mixer in the kitchen or in the bathroom, they begin to understand that grounding saves everyone living in the apartment from such danger.

The main reasons for the urgent establishment of grounding are as follows:

  • Huge risk of electrical injury. you may just feel a slight tingling sensation at first, but this is already considered a very alarming signal.
  • There is an opinion, which is confirmed by professional electricians with extensive experience, that in the absence of grounding, all built-in electronics can fail even before the end of the warranty. Delicate parts do not tolerate the accumulation of static charge: you will have to rather expensive repairs, and sometimes you will have to buy a new washing machine.

You should not wait until something burns out or someone from close people gets an electric shock. everything must be done on time.

If the light bulbs often start to burn out in the apartment, after you purchased the washing unit. this is the first call, you need to urgently do grounding.

Before doing the grounding with your own hands, carefully study the household appliances for the integrity of the insulation protection of the connection wire, whether there are any frayed wires inside. Damaged insulation can often cause electric shock, so grounding will not solve all problems.

If you live in a house with stationary electric stoves, then there is already grounding. the third wire is responsible for this. So you’re in luck and you don’t have to do anything.

We do grounding in a private house

If you have your own home, where there is no separate grounding, then the question of how to ground a new washing machine is very simple. Your home is a separate fortress, where each owner can do whatever he wants, but not in violation of the existing GOST standards. Before starting work, be sure to consult with an active electrician from among your friends or neighbors, you can invite him from the housing office.

Internal wiring should be done in the same way as the above options, and the connection should be made to your personal electrical panel. A private house has a number of advantages in organizing grounding with your own hands, the place around the house belongs to you and no one will be against the installation of a new structure.

Here are the detailed steps on how to do it yourself:

  • We are preparing three sections of an old water pipe 1.5 m long. the maximum length should be at least the depth to which the soil freezes in winter.
  • We sharpen one end by making a conical cut, then we drill a hole 5-10 mm in diameter at a height of one third from the lower end.
  • We dig a hole up to 60 cm deep and 1.5×1.5 m wide.
  • We drive in the pipes at a distance of 1.2 m from each other in the form of a triangle so that the upper end is 15 cm above the bottom of the pit.
  • We take a corner or reinforcement, cut it into three parts, measure it at the ends of the clogged pipes and connect the entire structure into a single whole.
  • We weld the ground wire to the upper part from the electrical panel located in the house.
  • This wire, made of a metal wire of large cross-section (at least 0.5 cm), is connected to the PE bus.

The grounding of the entire electrical home network is done, we fill the hole and put the sod in place, we designate the dimensions in any convenient way.

In the summer, when the hot period begins, it is necessary to water the pit with saline solution at least once a week (a pound of salt in a large bucket of water). If the temperature is below 30 0 С, water once a month. With this method, you will ensure an even distribution of static stress in dry ground.

one more little advice: it is better to make a reliable and correct grounding once than to complain later that they did not save expensive household appliances, and they burned out.

Grandfather’s way

When all houses had only metal pipes for plumbing and heating, our grandfathers came up with a rather original way: to ground all electrical appliances through connections to the battery. This method was very effective and very popular in the middle of the last century.

True, with such a connection, there are a number of disadvantages:

  • very dubious legality, because there are contradictions with the elementary rules for working with electrical wiring prescribed by GOST;
  • there are problems with pipes and batteries. leaks form from prolonged exposure to static electricity;
  • rather low reliability and there is a risk of electrical injury.

Some tenants are not afraid of the above factors, it is important for them that it is convenient for them, so they take a simple single-core copper wire, strip the vinyl protection from both sides and make an illegal connection.

In this case, one end is connected to the body of the washing machine, and the other is fixed to the central heating radiator or to the supply pipe using an ordinary clamp. So many people sign with their own hands a verdict about the imminent flooding of neighbors from below due to a breakthrough in the heating system in the near future.

Ways to ground the washing machine in different conditions

Purchasing a high-quality and reliable assistant for washing is only half the battle: for the safe use of new household appliances, it is necessary to properly ground the washing machine. For this, many call a master from the nearest service center, but we suggest doing everything yourself. You need to adhere to a certain method, which will tell you step by step how to ground the washing machine, even if there is no grounding in the apartment.

Do I need to ground household appliances

Many users doubt the advisability of grounding, but we assure you that for safe use it is necessary to ground all electrical equipment in the house. from a kettle to household appliances such as a washing machine, refrigerator or smart TV.

Modern houses of the new generation have stationary grounding. this can be determined by special three-phase sockets connecting to the general network. Houses of earlier construction are not equipped with grounding, the wire has to be laid independently, therefore, how to ground the washing machine and what is the best way to do it are quite relevant questions.

For skeptics, here are some examples:

  • A machine with a surge protector, when connected to a network where there is no ground, will accumulate a voltage of 110 V on the case, you can feel a strong tingling sensation when touched.
  • If the insulating layer of the wire on the case is violated, it will already be 220 V. when you touch it, you will get a good shake, if the unit is installed in the bathroom and water is spilled on the floor, then lethal outcome can take place.
  • Grounding guarantees protection of the delicate electronic filling from power surges, as well as from lightning strikes to the antenna on the roof of the building.

That is why you need to competently ground all electrical appliances and equipment in your home. this is safety for all residents and installed household appliances.

There are also houses where there is no grounding, and you live on the third floor, and it is unprofitable to pull the wire to the ground. Then we solve the problem using the potential equalization system. It is quite simple and is based on the fact that all objects that feed on electric current or are capable of conducting it are connected into a single system using metal wires.

Now, if you touch the body of the washing machine and the mixer at the same time, then the electric current will not go through your body. A prerequisite is the installation of a separate machine on your assistant, so that in case of any failure, she immediately disconnects from the apartment network.

All internal wiring must be done with solid wires, they should be docked only in special boxes with thorough insulation.
