Based on para. 7, paragraph 2 of Regulation No. 861, the maximum installed electric power is the largest amount of power that can be allocated by the electricity provider. It is measured in kilowatts, taken into account by common house and apartment appliances, paid according to the established tariff. But in some cases, the capacity is insufficient, and consumers begin to think about increasing it by legal means.
What is the "allocated power" of electricity
The allowed energy power in the apartment is the maximum value that the consumer can use at a time. The maximum load on the consumer network is always prescribed in the power supply contract.
For a complete understanding of the issue of permissible power, it is worth understanding its types. Today there is power:
- connected - the sum of the power indicators of all electrical equipment connected to the network;
- installed - indicated in the documentation for the equipment and provides for the functioning of the devices in normal mode;
- one-time - is determined on the basis of calculations of the power consumption of devices for a specific period of time;
- temporary or permitted - the maximum indicator that the energy supply company provides to the user.
The regulation of relations between the electricity provider and the consumer was approved by the RF Ministry of Energy on January 19, 2002.
What threatens to exceed the permissible power
On the basis of Decree of the Government of the Russian Federation No. 624, if the maximum load is exceeded, the electricity company has the right to restrict the consumer in access to the electricity grid. The reason is non-compliance with obligations under the power supply agreement.
In the event of an accident or during work on the power line, Energosbyt employees take measurements. In case of inaccuracies, they send notifications. The user must take measures to eliminate the excess of power within 10 days. The degree of his responsibility is determined by the violation of:
- ignoring notification after 10 days - turning off the power supply to the object;
- connection bypassing the line - charging a fine, recalculation of power at the maximum rate from the moment of verification, connection to the general network at the expense of the intruder;
- unconditional use - a penalty for the lack of agreement, recalculation according to the normal power indicator.
The basis for the termination of sanctions is documentary evidence of the adoption of measures. However, UOMPE, CCD and CCD devices are installed on the user's line.
The act of non-registration is drawn up in the presence of 2 witnesses, with a photo and video of the process.
Rules and regulations
Electrification of residential, administrative, industrial facilities is carried out on the basis of the technical specifications of the provider organization. One of the clauses of the contract indicates how much power will be allocated to the consumer network. The basis for the declaration of power and the formation of technical specifications are calculations.
Electricity connection to residential and public buildings is carried out in accordance with SP 31-110-2003 and temporary instruction RM 2696-01. The documents stipulate that the allocated electric power for houses-consumers of electricity of the 1st category is not standardized. Objects are connected based on applications.
Housing stock of the 2nd category has two electrification standards:
- from 5 to 7 kilowatts - the norm for a private house or apartment where a gas type of stove is installed;
- from 8 to 11 kW - for facilities where there is an electric stove.
The smallest capacity is accounted for by a small-sized apartment and a house built according to the social housing program.
To date, the regulations of 2006 apply. In buildings prior to this period, the release of power is much lower.
How to find out how much power is allocated
You can find out reliably how many kilowatts per apartment with a gas or electric stove, you can in this way:
- Contact your energy provider for help. The service is paid, depending on the region. A certificate from Mosenergosbyt, for example, depending on the type of facility, costs 1.3-3.1 thousand rubles.
- Find data in the power supply agreement or TU.
Independent calculations are made based on the parameters of the input protection device. The user needs to know the operating current, and then perform mathematical calculations. For example, the operating current indicator is 32 A. For calculating the maximum load limit, the formula P max = U x I nom x 0.8 is used; where U is the rated mains voltage. That is, 230 x 32 x 0.8 ≈ 5.5 kW.
Calculations based on meter readings are not always true due to the built-in load relay.
Calculation of the required power
Calculations are made if it is necessary to determine whether there is enough allocated volume. The maximum load is calculated as the sum of all devices turned on at a time. If you lose the data sheet or overwriting the sticker on the equipment, you should refer to the table data.
| Consumers | Power, W |
| Appliances | |
| Electric stove | 1100-6000 |
| Hair dryer | 450-2000 |
| Iron | 600-2000 |
| Heater | 1000-2400 |
| A vacuum cleaner | 400-2000 |
| TV | 100-400 |
| Washing machine | 1000-3000 |
| Refrigerator | 150-2000 |
| A computer | 400-750 |
| Kettle | 1000-3000 |
| Fan | 750-1700 |
| Tools | |
| Hammer drill | 600-1400 |
| Drill | 400-800 |
| Circular Saw | 750-1600 |
| Mowing machine | 750-2500 |
| Jigsaw | 250-700 |
| Circulation saw | 1800-2100 |
| Sander | 650-2200 |
| Household equipment | |
| Compressor | 750-2800 |
| Water pump | 500-900 |
| Air conditioning | 1000-3000 |
| Fan | 750-1700 |
| Gas boiler | 40-1000 |
| Electric boiler control | 1000 |
Having calculated the amount of consumption, you need to specify the reserve with increasing load. Devices will consume 20-30% more than the calculated value. The sum of the two indicators is the final result. If the rated power is lower than declared, you can apply for an additional 1-3 kW.
How many kilowatts does the wiring in the apartment withstand
Under ideal conditions, a standard copper conductor with a cross section of 2.5 mm2 can withstand a load of 5.9 kW, of aluminum - 4.4 kW.
Under operating conditions, the aluminum conductors of old houses with a cross section of 2.5 mm2 can withstand 3.5 kW at a current of 16 A. APPV at 6 mm2 do not burn out at a load of 5.5 kW and a current of 25 A. Wires with a cross section of 4 mm2 can withstand 4, 4 kW at a current of 25 A.
According to the rules of the PUE, a three-core copper wire with a cross section of 1.5 mm2 must withstand the maximum allowable load of 5.9 kW. 4 mm2 cable - 8.3 kW with a current of 28 A. A conductor with a cross section of 6 mm2 with a current of 46 A - 10.1 kW.
How to increase the allocated power
The power of electricity in an apartment or a private house can be increased on the basis of new technical conditions. The document is valid for 2 years. It prescribes:
- new indicators of permitted power;
- voltage parameters - 380 or 220 V;
- environmental standards;
- ways to control energy consumption and conservation.
Features of the appeal for individuals and legal organizations varies.
For individuals
Install additional power in stages:
- Collection of documents - a certificate or agreement on real estate ownership, a reference to the current capacity parameters, an agreement with an energy supplier, an act of separate operational responsibility.
- The implementation of the electrification of the building.
- Coordination with the provider company of the possibility of increasing capacity.
- The signing of the project in Energy Supervision.
- Check - the power plant is inspected and tested.
- Reporting and admission to increase power load. The first document is prepared by an employee of the energy company, the second is a representative of Energy Supervision.
All documents are sent to the supplier company, which makes the final decision.
For legal entities and companies
The sequence of the procedure is similar to the algorithm for private users. Only documents differ. An ordinary citizen presents a passport, and a legal entity - constituent papers. They are certified by wet round stamp and signature of the authorized person.
If the technical connection papers do not contain information about the maximum power parameters or they have been lost, the grid company has the right to reissue. It is implemented on the basis of a consumer statement in the form established by the organization. The electricity supplier in accordance with Regulation No. 861 shall not expand the list of documents and request additional data.
