Since the beginning of the year, inspections of electrical equipment in apartment buildings have already taken place in many regions of the Russian Federation. The inspectors paid special attention to metering devices. It turned out that many residents prefer to move electricity meters from the landing to their apartment. In what cases is this permissible, and when is it punishable, Bankiros.ru looked into it.

What to do after the transfer
Installation of the device at a new place of operation is carried out by a representative of energy sales. But the owner of the site needs to ensure that the device is put into operation correctly and that all necessary documents are completed:
- In order for the meter to be put into operation, you need to submit an application to the energy company. It indicates the consumer’s passport details, his contacts, and the number of the contract with the supplier.
- A company representative will fill out the documents and indicate the arrival time of the specialist to install the seal. The first sealing should be free.
- After putting the meter into operation, you need to make sure that it is reliably protected by a special shield with a transparent window for reading readings.
Who can connect
If at a general meeting (GM) the team made a positive decision to move meters, it is necessary that the work be carried out by qualified employees of the energy company.
Even if an outside electrician can perform the installation, certain authority is required to connect to the network and seal it. When the work is performed by a representative of the supplier, there will be no further claims against the consumer.
Meter transfer does not only involve technical processes. Representatives of the energy company must check the documents according to the boundary of division of balance sheet ownership, taking into account each device in the SNT.
Where can I install the measuring device?
It is possible, and in some cases necessary, to replace an electricity measuring device, taking into account the requirements for the new location:
- The device can be located in an electrical cabinet, on a panel or panel, the basis of which is a rigid structure.
- The metering device is installed at a distance from the ground of 0.8-1.7 m.
- If the electric meter is installed in an area that is easily polluted or may be subject to the harmful effects of precipitation and wind, then it is necessary to protect the unit by constructing a box. The box must be tightly locked with a key.
- The location of the meter should be convenient for a specialist who takes monthly energy consumption readings. It is also possible to transfer the device to an area that is not difficult to service if the device breaks down.
- The cable that enters the product body must correspond to the cross-section fixed for trouble-free supply.
- The electrician connects the cables so that there are no solders or twists on the input wire. By law, such defects are unacceptable and may prevent the correct calculation of kilowatts used.
- Fastening is carried out strictly in a vertical position. Deviation of no more than 1 degree is allowed.
Legislative norms
It is illegal for the power company to move the device to a utility pole. If a company representative insists on removal, the consumer has the right to refer to the following legislation and safety requirements:
- The Electrical Installation Rules (clause 1.5.27) indicate where the electricity meter should be located. It must be installed in a location suitable for maintenance. This place should have extremely low humidity, the temperature in winter should not be lower than 0 degrees. It is impossible to provide such conditions for operating the meter outdoors during the cold season.
- The PUE also gives the standard for placing the electric meter relative to the distance from the ground. The optimal location is at a height of 0.4 - 1.7 m.
- The same clause 1.5.27 of the Electrical Installation Rules says that the owner of the meter must monitor its safety; he is responsible for the device. But a gardener who is not always on the site cannot guarantee the safety of a device located outside the site.
Thus, mounting the device at a higher height on a pole violates the provisions of the main collection of standards for electrical installations. And taking readings from a meter installed higher than 1.7 m from the ground is not only inconvenient, but also dangerous. If the device hangs low outdoors, it will quickly be damaged.
It is understandable that electricity suppliers want to circumvent such requirements of regulations and legislation in order to gain additional profit. The rather high price for installing meters on poles will allow them to collect a certain amount. In addition, it is easier for inspectors to take readings from devices if they are located on street poles. There is no need to go to each plot and wait for the gardener to appear on the territory of the partnership. With this arrangement, the indicators of electricity meters are always at hand.
Therefore, energy companies will insist on such an installation location. What should SNT members do in this case?
Why is it not profitable to install a meter on poles?
- Indoors, without exposure to cold or hot air, the device gives more accurate readings. The error of street meters, compared to home ones, can reach 10%. Considering the high cost of electricity for consumers, the amount to pay for electricity increases significantly.
- A meter that was installed on a pole will fail faster and will last a shorter time.
- Dust, humid air, wind, hail - all these natural factors cannot but affect the operation of the device. With this arrangement, electricity meters more often require repairs, and the accuracy of the indicators is often lost.
- When the meter is installed on the street, you need to monitor it. After all, even from hooligan motives, someone can damage the device, and theft is not excluded, despite reliable fastening and connection to the electrical network.
- Energy companies force people to install electricity meters on the street, often counting on additional profits. After all, if the meter breaks down or completely fails, the consumer needs to pay for a new control device, a new installation, a new seal.
- Also interested in the fact that electricity meters in the sector of private houses, dachas, and garden plots are located on transmission line supports are also those companies that sell meters and check them.
There are many reasons for concern among owners of plots in holiday villages, gardening partnerships, and in the private sector. And therefore the question is whether the requirement to move the electric meter outside the house and even the yard is legal.
The procedure for moving an electric meter in an apartment
In case of detection of defects or deviations of the meter from normal operation).
- The owner’s own desire (does not like the design or has a desire to switch to multi-tariff metering of energy consumption).
- Step-by-step instructions Procedure for replacing the meter.
- You write a statement to the regional structure of Energosbyt with a request to carry out this action. It is submitted on the basis of a document on ownership of the living space and a passport. You can submit either in person or online.
- Based on your application, a work order form is issued.
- The same organization will advise you on the meter model - which one is right for you - depending on which tariff plan you choose, according to your financial capabilities.
Calibration interval
Depending on the model, the device can last up to 25 years. In addition, there is also a shelf life and guaranteed performance. They all differ from each other. To link these terms, the meter interverification interval (MPI) is used. It determines how many years of operation the device will withstand within a given error. The quality of different meter models varies, and the inspection frequency can range from 4 to 16 years.
When releasing a new product, the manufacturer's accredited service checks the accuracy of the readings and seals the device. PUEs require that there be a seal with the manufacturer's mark on the screws that secure the meter casing.
How to move an electric meter during redevelopment
Relocating an electricity meter is a common procedure during redevelopment or renovation of a house, office building, store or other structure. Is it possible to change the installation location of the meter without approvals and permits? Let's figure it out.
Rules for electrical installations
It is possible to change the location of the electricity meter at the request of the owner of an apartment, house or non-residential premises only if the transfer does not contradict the PUE approved by Order of the Ministry of Energy of the Russian Federation dated July 8, 2002 N 204.
To resolve the issue of moving an electricity meter, you must submit a corresponding written application addressed to the head of the district energy sales department. After this, a specialist will come to your apartment or house and give an opinion on whether it is possible to move the electric meter.
If such a possibility exists and if this does not contradict the requirements of the Electrical Installation Rules, specialists from the organization supplying you with electricity carry out work to change the location of the meter.
Basic requirements for installation sites for electricity meters
- Meters, according to the requirements of regulatory documents, must be located in dry rooms that are easily accessible for maintenance, in a place that is sufficiently free and not cramped for work, with a temperature in winter not lower than 0oC.
- Meters of general industrial design are not allowed to be installed in rooms where, due to production conditions, the temperature can often exceed +40oC, as well as in rooms with aggressive environments.
- It is allowed to place meters in unheated rooms and corridors of switchgears of power plants and substations, as well as in outdoor cabinets.
In this case, provision should be made for their stationary insulation for the winter through insulating cabinets, hoods with heating of the air inside them with an electric lamp or heating element to ensure a positive temperature inside the hood, but not higher than +20oC. - Meters must be installed in cabinets, chambers of complete switchgears (KRU, KRUN), on panels, switchboards, in niches, on walls with a rigid structure.
- It is allowed to mount meters on wooden, plastic or metal panels.
- The height from the floor to the meter terminal box should be in the range of 0.8 - 1.7 m. A height of less than 0.8 m is allowed.
- Calculation means for accounting for electrical energy should be installed at the boundaries of operational responsibility between consumers and the power transmission organization: at the inputs of the ASU, main switchboard and at the low-voltage inputs of power transformers TP, the power of which is fully used by consumers of the buildings, as well as at the inputs to apartments of residential buildings.
- Calculation methods for accounting for electrical energy must be established in such a way that, in order to control the level of electrical energy consumption, ensure the technical and physical capabilities of uninterrupted access to them by responsible employees of Gosenergonadzor, the supplier of electrical energy, the power transmission organization and the consumer of electrical energy.
- For safe installation and replacement of meters in networks with voltages up to 380 V, it must be possible to turn off the meter by a switching device or fuses installed before it at a distance of no more than 10 meters. Voltage relief must be provided from all phases connected to the meter.
When changing the installation location of the electric meter, it is necessary to make adjustments to the existing power supply design of the building.
Redevelopment of the power supply system
If, in addition to changing the location of the meter, you want to change the electrical wiring, its circuit, etc., then it is worth remembering that according to the PUE it is necessary:
- replace two-wire wiring with three-wire wiring;
- installation of additional devices is possible only with the installation of equipment that increases the electrical safety of the building or premises.
If you want to increase the electrical capabilities of your premises or building, then you will need additional power, the obtaining and installation of which requires approval and permission from the same supply organization.
Our company will not only help you install the meter, but will also design and coordinate a new power supply system for your needs. We also provide certification services for building facades. Call!
Beware, scammers!
Not everyone understands the meaning and order of innovations. And scammers take advantage of this. They try to impose paid services on apartment owners.
Now the service organization notifies the owners in writing about the need to replace the old electric meter, which has reached the end of its service life, with a new one.
It’s easy to buy a database of owners with electric meter data on the Internet. Fraudsters call clients by manipulating laws. The main goal of scammers is to force the owner to change the device at his own expense.
They often go around apartments and, using intimidation with large fines, force them to change a working electric meter. Draw up a contract for the sale of an electric meter and services for its replacement. They take money. To install the seal, it is recommended to contact the energy sales service.
It is impossible to sue for unauthorized actions of a third party. The owner signs contracts and pays for purchased equipment and services voluntarily.
If the owner is forced to provide a service to replace the electric meter, you need to call the organization and find out whether specialists have been sent to your address.

Electrical supply
Before installing an electric meter in a private house on the street or indoors, a set of measures must be completed that are necessary for laying wires to the site. Of course, if there is no electricity. The legislation allows for water supply even if there are no buildings on the territory yet. However, in this case, the owner must have permission for individual housing construction, and the land must have the appropriate status.
How to connect electricity to a private house? First you need to collect documents to obtain a permit. The package must include title papers, a citizen’s passport, a site plan and a diagram of the location of power lines. Then you should make a corresponding statement.
All documents are submitted to the energy supplier. He is obliged to consider the application within a month and give a response. If it is positive, the technical work to complete the task begins. When the distribution point is located near the site, electricity can be installed in a private house relatively quickly. This will take about a couple of months. And when the wires have already been laid, you can start purchasing a meter and find out the rules for its installation.
Who should change the meter and at whose expense
Until recently, the responsibility for replacing the electric meter rested with the owner. However, on July 1, 2022, Government Decree No. 554 of April 18, 2020 “On amendments to certain acts of the Government of the Russian Federation on improving the organization of electrical energy metering” came into force.
In case of installation of new equipment, it is recommended to install modern intelligent electricity metering devices. But not everything is so simple.
First of all, meters that have failed or whose service life has expired are subject to free replacement. In addition, owners who do not have electricity meters for one reason or another have the right to free installation of electricity meters.
At the same time, electric meters will be replaced with smart devices. Installation of such meters is beneficial for resource supply organizations. Therefore, the Government of the Russian Federation adopted the Federal Law No. 422 dated May 4, 2012, which stipulates who should pay for the acquisition, installation and commissioning of automated control systems.
- The law formulates the concepts of “intelligent accounting system” and defines how to understand “fully independent”, “automated” and “remote system”;
- The deadlines for the transition to an intelligent accounting system have been determined, which allows you to independently collect data and transmit it remotely to the dispatcher according to a specific schedule;
- The costs of technical re-equipment are borne by resource-supplying and supplying organizations. Moreover, expenses are prohibited from being included in tariffs;
- Provision is made for the gradual replacement of electricity meters as they fail, their service life expires, or the calibration interval expires. All new buildings put into operation must be equipped with smart electricity meters.
That is, service organizations are obliged to change the electricity meter in the apartment, entrance, or staircase themselves. At the same time, they should not worry whether a meter is installed in a privatized or non-privatized apartment or whether it provides electricity metering in a private house. The owner does not have to buy the device and pay for its installation.
Rules for transferring an electric meter
If there is a need to move the meter to a new location, dismantling, moving and installation work should first be agreed upon with the management company. It is necessary to contact Energonadzor and write a statement in which you should justify the reason for the transfer of the product.
Next, electricity meters are installed where permitted by law. On a new site in households or outside the boundaries of a private house, it will be sealed again. To do this, you need to write a second application.
Difficulties may arise when moving the device from the landing to an apartment in a multi-story building. The device can be installed if its new location is recorded in the design and estimate documentation.
If there is no such area on the diagram, the resident will have to draw up and submit his own project to the experts of the regulatory service. Moreover, its development is paid for with the applicant’s personal funds.
Having received the necessary permission, you can begin unsealing, transferring and final installation of the device. There is no need to contact a Housing Authority electrician for installation. You can do it on your own.
But the sealing is carried out by a specialist with the necessary qualifications. If he works privately, he must have a license to perform the relevant work.
The choice of an electrician falls on the shoulders of the owner of the apartment or house. If the electrician does not have the necessary qualifications, not only he, but also the customer is responsible for illegal actions in installing the device.
As a result of the transfer of the metering device, the owner receives 2 certificates of completion of the procedure - about unsealing and sealing. The work of Electronadzor specialists must be paid in advance, before they leave for the apartment.

Relocating an electrical panel in a house or apartment
Typically, the shield is transferred in the following cases:
- Replacement of wiring in a private house during a major renovation. After its completion, the electrical box is moved from the pole into the house.
- Sometimes during construction the electrical panel is moved from the pole to the cabin.
- When moving into a new apartment.
- If there is a need to connect additional electricity consumers, and the switchboard does not meet electrical safety requirements or there is a need to increase the number of machines.
- Upon completion of the construction of the cottage, the electrical panel is moved from the pole to the house.
The easiest way to move an electrical panel is to a new apartment. Nothing bothers the owner, and repairs are still done upon move-in.
Builders are trying to save money both on materials and on work. They install the cheapest machines in the panel, and the box is not recessed into the wall. This is done not only in panel houses, but also in brick houses.
Therefore, when moving into an apartment, owners try to change its location so that it is aesthetically pleasing. At the same time, it did not take up any useful space and met all safety requirements. You can leave it in the same place, replacing the protection devices and checking the quality of the electrical wiring. We will have to install new machines, the ratings of which correspond to the power of the owner’s equipment. For example, as shown in the figure below.
In panel houses, a wall box is usually installed, since it is not always possible and not always permitted to cut a niche in the wall. It is located near the front door in such a way that the electrical panel is in the way and is located on the passage.
It is prohibited to ditch load-bearing walls in panel houses (according to Moscow Government Decree No. 73-PP dated February 8, 2005 “On the procedure for reconstructing premises in residential buildings in the city of Moscow”, as well as Government Decree No. 508 (Clause 11.3 and 11.11 of Appendix No. 1 Therefore, choose overhead models.But if the shield is installed on a non-load-bearing partition, then you can use built-in boxes.
The owner does not have to turn off the electricity so often. Therefore, it is advisable to leave it near the front door and move it to a convenient place. But the top of the box should not be higher than 1.8 m from the floor level. When moving from one place to another, do not forget about safety requirements. It is not recommended to place it as shown in the figure below.
In this case, turning off the electricity will be difficult, which is contrary to the requirements of the PUE. You should find another place to place it.
When replacing electrical wiring in an apartment, it is recommended to move the electrical panel from the entrance to the apartment. In this case, leave the electricity meter on the site. In this case, you can safely expand the input cable that goes from the meter to the apartment.
If the meter remains in the floor panel, then no approvals are required, and the transfer can be done with your own hands. If the owner does not have the skills to work with electricity, it is better to call a qualified specialist.
Requirements for the location of the electrical panel
If the transfer to another location is carried out on your own, then it should be taken into account that the new point must comply with the requirements of the PUE.
It is prohibited to install electrical equipment in places:
- High humidity.
- The location should be free of dust. Such places include closed closets with clothes, pantries, etc.
- The electrical panel must be located in a visible place. Usually near the front door.
- Access to it should not be obstructed. In the event of an emergency, there must be free access to the machines to quickly disconnect consumers.
Reasons and procedure for transfer
A non-closing communal electrical panel is a reason to move the meter into the house to avoid vandalism
After solving the problem of the legality of the actions taken, two other important questions should be dealt with: why this needs to be done at all and how to move the electric meter from the entrance to the apartment in compliance with all installation rules (in accordance with the requirements of the PUE).
Reasons for moving the electricity meter
After moving the electric meter into your apartment, you don’t have to worry about its safety and can easily track the current readings using the device’s indicator.
It is possible to transfer electricity meters from the entrance to the apartment in cases where this operation is really in demand and agreed upon with the relevant services.
Device installation procedure
It is prohibited by law to independently remove the seal from the electric meter.
The sequence of operations performed when moving an electric meter:
- Completely de-energize the home network by turning off the input circuit breaker.
- Remove the cover of the electric meter contact panel with the seal, under which there are connecting terminals with a set of supply conductors.
- Take a photograph of the entire terminal block, which will allow you to record the order in which the individual wires are connected.
- After this, you can safely disconnect them to free the electric meter and subsequently move it to a previously prepared place.
All subsequent operations are associated with the direct transfer of the device. They are performed strictly in the following sequence:
In a selected and pre-prepared place in the room, install a cabinet or base for the meter, securely fixed to the wall
The installation height is selected taking into account the convenience of taking readings. Lay a harness to it with conductors stretched from the old place. Connect the pre-labeled wires to the corresponding terminals of the meter. When connecting them, it is important to ensure that the screw fastenings are tightened as far as possible and cannot become loose over time. Invite a representative of the energy service, who will evaluate the work done and seal the device installed in the new location. Only after a visit from an employee of the energy supply organization can all work be considered completed, and the newly installed electricity meter be legally operated. Only after a visit from an employee of the energy supply organization can all work be considered completed, and the newly installed electricity meter be considered legally operated
Only after a visit from an employee of the energy supply organization can all work be considered completed, and the newly installed electricity meter be considered legally operated.
Which electricity meter is best to install in an apartment?
The topic of today's article: which meter to install in an apartment. Formally, this should be handled by the company that sells electricity, but in practice it turns out that this is a problem for buyers of this very electricity. As in the famous aphorism of Ilf and Petrov about drowning people and the work of helping them. Apartment residents are required to have an electricity meter and replace it if it is outdated and does not meet modern requirements. This is where it turns out that choosing the right counter is not an easy task. There are so many offers that you can get confused. Choosing exactly what you need from hundreds of possible options seems completely unrealistic. Let's try to understand this ocean of metering devices, which electricity meter is better to install in an apartment or private house..
Unlike induction, electronic devices are multifunctional and can be designed for several tariffs. They are more compact in size, which means they take up less space on the input panel. Their cost is higher, and in terms of working life they are inferior to induction ones.

Option 1
This is the simplest circuit of an input panel with an electricity meter. It shows the TN-S grounding system, that is, when separate independent neutral working and neutral protective conductors come from the power source. In this single-phase switchboard circuit, there is a two-pole circuit breaker at the input.
Here and in subsequent diagrams, the ratings and characteristics of protective devices are chosen arbitrarily. Yours may differ, but the very essence of the connections between circuit breakers and other protective devices remains the same.
After the opening machine there is a counter. To register it, the input switching device and the electricity meter itself must be sealed. Next come single-pole group circuit breakers. The phase is always supplied to the circuit breakers, and the zero to the zero bus. It turns out that all neutral working conductors of different groups are combined with each other, and phase conductors are switched using automatic machines.
This version of the scheme is the simplest and is very often found at various sites.
Who should change
You can also transfer the counter yourself. To do this, you must have work experience and a clearance level.
Also, the chosen location must meet a number of requirements. If you do not have the required qualifications, you should not take up the job.
There is a high probability of an undesirable result with the subsequent involvement of a professional electrician. You will also need to first agree on this issue with the company that provides electricity.
The optimal solution would be to hire a specialist who will perform the sealing after all installation work. This procedure is mandatory regardless of the performer.
As a result, two acts will be issued. The first is about removing the seal of the old meter, and the second is about sealing the new one. These acts must be kept together with the meter’s passport until the next verification.

Every user living in apartment buildings is familiar with the inconvenience of operating electric meters installed on staircases or other common areas. Most of them, over time, try to change the situation and move the metering device closer to their immediate place of residence, that is, to a house or apartment. However, this is not so easy to do, since formally it falls under the responsibility of the energy supply company, from which permission for the transfer must be obtained. To understand whether it is possible to move an electricity meter into an apartment, you will first need to understand all the nuances of this problem.
Look at reviews about us
After renovating the kitchen, we decided to buy a new stove for the interior. We bought it and started looking for someone who would connect it. We searched in Yandex, looked mainly by price. We found the SAM company. The technician arrived on the day of the call and connected the stove in literally 2 hours. There were problems with the socket. But the master decided it. I am very pleased. I advise everyone to contact the SAM company.
We bought a new 2-room apartment in a new building. On the advice of a friend, I decided to contact the SAM company for electrical installation. On the same day, their specialist came to my site to calculate the cost. The next day a detailed estimate was ready. After the work was completed, I received warranty service for a period of 2 years. I recommend to everyone.
We actually had an unusual story with electrical installation in the business center. First, they hired a private crew in the hope of doing it cheaper, after 2 days they “ran away” from the site, and we had to urgently look for other performers. So, in the end, electricians from the SEM company completed the work, under a contract and without an advance payment. They helped me purchase the material 10% cheaper. Everything was completed on time.
Hello. My chandelier is broken. The SAM company arrived. They fixed the chandelier and even fixed the socket for free. Very polite and responsive staff. And the price is low. Contact SAM. You will not regret.
I completed the cottage and ordered turnkey electrical installation. I didn’t bother purchasing materials myself. I decided to relieve myself of all the “headaches” and trusted the decisions of the employees, I just had to pay for the materials on time, and everything was done for me. It's great when there are companies that take care of everything. I was afraid to contact private owners; after all, this is a cottage for permanent residence, not a garage. Thank you!
It was necessary to change the socket in the apartment. We started calling specialists, they either didn’t call back or didn’t pick up the phone at all. We found the SAM company. The repairman arrived on time and changed the socket for us in just an hour. I am very pleased. And the price was no more expensive than others. Thanks to SAM company. I recommend to everyone.
Transferring a shield in production
Moving an input panel in production is a complex and time-consuming process. It is necessary to submit an application and receive technical conditions for moving the ASU, and order a project.
Based on these documents, an application is submitted to the power grid. An agreement is concluded based on the project. After which the work is carried out.
Upon completion of installation, the necessary checks and measurements are carried out. The customer is issued a new act of delimitation of balance sheet ownership and an act of delimitation of operational responsibility.
If it is necessary to move the electrical panel after the metering devices, then this work is performed by the company’s electricians. No additional approvals are required.
However, all new points of electricity consumers and the location of the panel with automatic machines must be displayed on the plan of the enterprise. Otherwise, regulatory authorities will impose a fine on the organization.
If the enterprise is small and does not have an electrician on staff, then all this work is performed by electric network workers under a separate contract.
Sequencing
There is a certain procedure for reinstalling the electricity meter:
- A new device is purchased with seals, a passport and permission to work.
- An application is submitted. To make things easier, many organizations accept verbal requests. If the work is performed by a third-party company, then an application must be written to the management company, homeowners association or energy sales organization in order to put the device into operation (clause 81 of RF PP No. 354).
- The device is being installed. The meter is changed taking into account all the rules specified in PES-7. An incorrect connection will not allow the device to be put into operation.
- An employee is invited to carry out inspection and sealing and draw up a corresponding report.
Who should change
Also, the chosen location must meet a number of requirements. If you do not have the required qualifications, you should not take up the job.
There is a high probability of an undesirable result with the subsequent involvement of a professional electrician. You will also need to first agree on this issue with the company that provides electricity.
The optimal solution would be to hire a specialist who will perform the sealing after all installation work. This procedure is mandatory regardless of the performer.

Device selection
There is a wide selection of electricity meters on sale. Therefore, it is necessary to decide which model is needed for a specific task. First of all, you should know that devices are divided into two broad groups according to their operating principle. They are:
- electronic;
- induction.
Until recently, it was the induction model that could be seen in the house. It is now considered obsolete. This device is not accurate enough
So it is important to buy an electronic sample. If an old-style device (induction) was previously installed, the law requires replacing the electric meter in a private house, as well as in an apartment
Before purchasing, you need to make sure that the model has a seal.
Moreover, it is important to find out the timing of its installation. For the three-phase version, it is permissible for sealing to be carried out within a year maximum until the device is sold to the end user
If the meter is single-phase, then the seal is considered valid for 2 years.

How many phases should I take the device for? It depends on what wires are connected to the site. If possible, it is better to achieve the supply of 3 phases: they will not be superfluous in the house. True, this is not always technically feasible. Therefore, before installing electricity, you should find out this point, so that you can immediately buy a suitable meter.
Additionally, it is worth studying the documents for the device, finding out its accuracy class and rated current. The consumer is interested in purchasing the most accurate device. And if it is installed in a house rather than an apartment, it is more profitable to buy dual-mode models. This means that they charge electricity at different rates during the day and at night.
After all, living in a separate building requires greater energy consumption, and you will also need night lighting of the area. It is more prudent to take advantage of the opportunity and save on costs, which is possible with the installation of a dual-mode device.
Artist selection
Users who believe that they can handle this problem on their own have the opportunity to do without unnecessary costs. The downside of this option is possible errors during switching, which will result in problems recognizing the correctness of the transfer. To be on the safe side, it is wiser to invite a specialist who, in addition to installing the device, has the right to seal it. The only disadvantage of this approach is the need to pay for the work performed at the tariff provided by the Energosbyt service.
Electricity meters can be installed in apartments only if all legal requirements are met. To comply with them, you need to worry in advance about choosing a place to install a portable electric meter and inviting a specialist. The best option is to hire an electrician from local energy services who is authorized to seal all brands of metering devices.
Principles for selecting an electrical panel
The drawn up diagram allows you to estimate how many automatic machines, RCDs, etc. will be in the system. Modern shields have a modular design. To assemble an electrical panel in an apartment, elements that are multiples of 18 mm in width are used, that is, each module has a size of 18 mm. An RCD or DIF-automatic device occupies two modules in width, and an automatic circuit breaker occupies one module.
Principles for choosing an electrical panel:
- The size must be taken with a reserve. This will allow you to later move the shield to another location or upgrade the circuit without problems;
- The selection of the shield must be carried out taking into account the type of electrical wiring. There are models for external (overhead) or hidden wiring (built-in);
- It is advisable to give preference to plastic shields that definitely do not conduct current.
