Residential owners need to know how to install an electric meter, even if they are sure that there is no need to do this on their own.
Consider the basic rules for the installation of such devices in apartments and private houses, which must be strictly observed.
Consumers of electricity should find out all the nuances of installing and operating electricity meters.
Indeed, in the absence of a device that will keep records of the consumed resource, not a single energy supply company will draw up an agreement with residents. This means that electricity will not be available.
What you need to know
When it comes to electricity and electrical appliances, safety rules should not be underestimated.
There are certain requirements for the installation of meters, which apartment owners and service companies should comply with.
Definitions
An electrical energy meter is a device that measures the consumption of electricity (alternating or direct current).
The meter with ASKUE involves the connection of additional cables through which information is transmitted. install a numbered seal.
To keep records of active and reactive AC energy, a single or three-phase device is installed.
Accounting for DC energy consumption is carried out using electrodynamic meters. The consumed electric power is determined by counting mechanisms.
There are such types of electricity meters:
Meter classifications:
- three-phase, single-phase;
- single-tariff, multi-tariff;
- with conventional and simplified schemes for taking readings;
- having digital or mechanical indication of indications;
- super accurate, normal.
What are its functions
Without this device, it will not be possible to use electricity, as they will refuse to draw up a contract with the user.
The purpose of the meter is to keep track of the amount of electricity that is consumed. Basic functions:
- used to measure electricity;
- displays data on the consumed resource on counters or an electronic form of the scoreboard.
Additional functions:
- it is possible to record the amount of electricity consumed in the memory of the device;
- you can display data on the consumption and amount of free space in the storages;
- displaying the set tariff.
The meters can program up to 4 tariffs for 16 time zones per day.
Modern devices can be configured in such a way that they can record energy consumption for each month separately.
This gives you the opportunity to save money on bills. It is possible to keep records of energy loss, effective phase voltage, current and frequency.
Current regulations
Installation of electricity meters and their use is carried out in accordance with several laws, rules, regulations.
Worth following:
- Rules for the technical operation of consumer electrical installations (chapter 2.11).
- Rules for the installation of electrical installations.
Rules for installing an electric meter in an apartment
If consumers are not attentive to the consumption of energy resources, then its spending will become colossal. Do not underestimate the importance of instrument installation.
In accordance with the new rules, the electric meter is changed in this case:
To prevent fire or damage to the device, it is worth replacing it. Consumers will be allowed to use a larger load when replacing the measuring device and the circuit breaker.
Change counters:
- if the inter-verification period has expired (in this case, normal verification cannot be carried out);
- if the old electric meter is faulty;
- if a planned replacement of devices is carried out.
Where to go
Inside the apartment, the citizen himself is responsible for everything, which takes the premises for rent. For the same objects that outside the premises, representatives of the managing enterprise should think.
The managing organization changes the meters at its own expense and organizes the installation of the devices itself.
How much does it cost (price)
Who should pay for the installation of the meter? Repair work, dismantling and installation is carried out at the expense of the owner of the apartment.
If the meter is mounted indoors, then the consumer will bear the costs. This applies only to privatized objects.
When installing a meter in municipal housing, payment is made by the municipality. Tenants do not need to pay even when the house is served by housing cooperatives.
If the electricity meter is installed on the landing, then the costs will be borne.
If the consumer is guilty of damaging the device, then he himself must pay for its replacement. Scheduled installation of new devices is carried out at the expense of the service company.
The price of replacing the device is set from the cost of the device itself and the cost of installation services (in Moscow it is approximately 800 rubles).
Installation costs may vary by region. On average, it is 500 rubles.
Some companies ask for the installation of electricity meters from 1000 rubles. for single-phase models and 1500 rubles. for three phase. If the device is set to two tariffs, the cost increases.
At what height do you need
Basic requirements to consider:
| Devices are mounted by those that have passed the state verification | It is often carried out already at the factory, which is confirmed by a seal consisting of Arabic and Roman numerals. |
| Installation height of the electric meter in the apartment - 0.8 - 1.7 m | The minimum height is 0.4. The device is mounted in the apartment on the switchboard in the entrances installed at a specific height. Such intervals are chosen in order to make it convenient to take meter readings. |
| Installation is carried out in the correct horizontal and vertical position | A deviation of 1 degree is allowed. For an electronic sample, such a requirement is not important, but the norm should be observed |
| Special rules regarding switchboard, no drawer | The main thing is to provide easy access to connect wires, carry out installation and dismantling |
| When installing three-phase devices for 380 V | It is necessary to install a disconnecting device (knife switches, switches, etc.). Distance - up to 10 m |
Do-it-yourself replacement
Residential property owners have the right to install meters themselves. Only in this case, be sure to follow the installation rules.
The meter can be mounted in a cabinet, a chamber of complete distribution devices, on panels, a shield, in a niche, on a wall of a rigid structure.
Devices can be installed on a wooden, plastic, metal shield. So, you have decided to install the device yourself. The first step is to conclude an agreement with the electricity supplier.
Prepare documents for receiving settlement accounts to pay for consumed electricity.
The power supply company will issue technical certificates, which will reflect the type of device, the input protection circuit breaker, the length of the wires, etc.
To obtain permission to operate an electric meter, write an application indicating:
- agreement or personal account number;
- address and contacts.

Once the instrument is installed, it must be commissioned. For this, documents are prepared by an employee of the supplier company after inspecting and checking whether the circuit is connected correctly.
The act must contain information about:
- type and number of the device;
- initial indications;
- the number of the seal that is installed.
After receiving the technical documents, you can begin the installation. If the device is mounted indoors, use the YUR box or mounting boards.
It is desirable to install protection elements in the shield instead of plugs. The connection must follow the following scheme: 
Mounting order
The process of installing an electricity consumption meter is quite simple:
| An energy sales worker will remove the seal from an old appliance | And write down test results |
| The person who will mount the counter | Must be sure that there is no current in the network. The machine is turned off and removed |
| When the wires and cables are disconnected | Mount a new device, reconnecting all loads and the supply line |
| Quality control is carried out | Each wire connection on the terminal to eliminate sparking |
| Supply voltage to the meter | And turn on the machine, fuse and RCD |
| A thorough check is being made | Is the meter working properly? |
| It needs to be sealed | And enter it into the State Register of Trusted Devices |
Twisting, soldering on input cables should not be allowed. It should be a single piece from driveways to metering devices.
When connecting the device, pay attention to the color coding:
Apartment
Let's describe the basic rules for installing electricity meters in an apartment building. They do not install meters in apartments on their own - representatives of the energy company do this.
In a multi-storey building, the meter is placed on a common area. Although recently they have been practicing their transfer to the apartment itself.
In a new building, the device is mounted in an electrical panel, which is located in the hallway. Machine guns are located nearby.
They are connected to incoming machines, de-energizing the main circuit.
From the main machines, electricity goes to the meter, and then through wiring to other machines. It is worth taking care of grounding to prevent short circuits.
In the non-privatized
Counters can be placed indoors or on landings. In the latter case, the device should be considered a public object.
It is worth stipulating in an agreement with the Criminal Code who will bear the costs if it is necessary to replace the electricity meter.
To carry out the installation, you need to submit an application to the management company. Shows reason for replacement and date of last installation.
In the communal
Meters must be installed by residents. If such an obligation is not fulfilled in time, then the energy supply company operates. There are two types of devices - accounting and settlement.
The first option does not involve sealing or other actions by government agencies. The counter is not monitored.
This is an internal tool so that you can keep track of energy consumption by individual consumers. In the second case, the installation is carried out only by specialists, since verification is required.
When installing the counter, it is worth considering the following rules:
- The input and output circuits of the device are switched.
- Grounding is carried out so that in case of phase imbalance and short circuits, the safety of all electrical appliances in the room is ensured.
- The input current circuit is connected to the circuit breakers, and then to the meters.
- Connect the output of the counters to the introductory automata or a group of automata.
- A trial run is in progress.
In a private house on the street
The place of installation may not be heated. It can also be a switchgear corridor of a power plant and a substation, an outdoor cabinet.
It is only worth organizing stationary heating in the winter. For this, insulating cabinets, heated caps are installed. The maximum temperature that is allowed is 20 degrees above zero.

Installation of electricity meters in the open air outside the premises is carried out taking into account several technical and operational standards.
It is best to place the device on the facade of the building. In this case, the height should be 0.8 - 1.7 m. Installation can be carried out on the supports of concrete pillars, if they are located on the territory of the building.
Protective circuit breakers are installed in electrical panels. A group of machines for each consumer is installed indoors.
The process is like this:
What are the advantages of outdoor installation? - Controllers will not bother you once again. Only here it is necessary to take care that the shield or box is airtight and insulated.
When installing the appliance indoors, choose a dry room. But in any case, it is necessary to ensure free access for an employee of the power supply company to take readings.
If you install the device yourself, do not forget about safety rules. It must not be installed under voltage.
Be sure to turn off the introductory machine. Well, if you have doubts about the correct installation, contact the experts.
