List of important documents
If you intend to take a responsible approach to connecting electricity to your home, then first you need to draw up an application of a certain form and bring it to the organization responsible for the service power grids. There you will be given a special permit to supply electricity. In addition to the application, you will have to prepare copies of documents that must be certified by a notary. Their list is as follows:
- civil passport and identification number;
- documents confirming the ownership of the house and land;
- a power of attorney if another person represents your interests in the institution;
- a special project for the electrification of a site and a dwelling, containing information about all energy-consuming devices and their capacity in general;
- building permit. It is required to supply electricity to an empty area.
Once the above documents have been prepared, they sent by registered mail. It would not hurt to attach an inventory of the attached documents to them. If any important document is not found, the organization will notify you about this no later than 6 days from the date of submission. Sometimes a person is asked to send originals of documents to confirm the specified information.
The organization responsible for connecting electricity to a site without buildings and with buildings uses the documents you sent as a basis for drawing up technical specifications. Without them, it will not be possible to supply electricity to the site.
The documents must reflect the technical characteristics of the input of electricity into a private house. There must be data on the presence of a single-phase or three-phase cable. When all the above steps are completed, the owner of the infield has the opportunity to connect electricity to a private house. The technical conditions must be fulfilled no later than two years from the date of their formation.
Sometimes it happens that due to the peculiarities of the technical conditions of the power grids, it is impossible to supply electricity. Often there is a situation when the power of the calculated load is higher than the nominal value of the network. In such cases, the organization sends a written notice reflecting the aforementioned point to the customer of the service. Please note that it is not possible to appeal the decision in this case.
Electricity connection costs
To check whether all the technical conditions comply with the standards, you will have to spend about 500 rubles. Electricity connection works differ in cost. The exact price is determined depending on the capacity of the connected line. If the power in the network to the site is more than 15 kW, then the cost of connecting electricity is 600 rubles. In this case, the work is carried out on the condition that the gander for supplying electricity is removed from the city power line by no more than 300 m.For rural areas, the same parameter is 500 m.
When it is required to install a new power grid, providing for the creation of a long-distance connection, it is necessary to obtain permission from the local authorities.
Points of the external electrification project
It is necessary to proceed to the development of a project for the external electrification of a private house when the preparation of technical conditions by the organization responsible for servicing the power grids has been completed. When a project is created, the institution is guided by the site electrification specifications as a base. To do this work, you will need:
- Geodetic site plan. The document contains information about the location of cable and overhead lines, communications.
- Electricity metering unit project. It reflects information about the nominal value of the input machine and the current.
- SIP cable connection project. It is carried out to the metering station from the line of the transformer substation supports. She is, in turn, on the site.
- Calculation of the grounding project and its further development.
When supplying three-phase networks, the power of the transformer is calculated, the throughput of the network and the switchboard with the switch cabinet are calculated. It is necessary to obtain approval for the documentation from the organization that is responsible for maintaining the electrical networks at the location of the house to be connected. Sometimes they may also require obtaining consent from the regional authorities.
Conducting electricity to the site
It must be remembered that the power supply organization is responsible for the supply of electricity outside the boundaries of the site. The work itself is carried out on the basis of project documentation. The owner of this territory must himself connect the electricity to the house on the site. Installation costs may vary.
The calculation of the price is carried out individually for each specific case. Features of the supply of power grids are that the work is carried out in stages. It is imperative to comply with the technical requirements and agree on the external connection project. It contains steps such as:
- Access to the house and electricity site.
- Confirmation of the functionality of devices used in the future to control the consumption of electricity.
- Placing a seal on metering devices.
- Formation of an act of completed work.
- Signing a contract for the supply of electricity.
As soon as the approval for the connection of electricity is received, they proceed directly to the laying of the cable. Following this, they make the wiring of electricity in a private home.
Basic connection rules
If a single-phase line is supposed to be laid, a cable with a minimum cross-section of 6 mm must be used. It must have a copper core. You can also take a cable with an aluminum core of 16 mm. Reliable isolation is imperative. Wires must be protected to prevent kinking and damage. Under the supports, the electrical networks of two cables are fed. One of them is phase, the other is zero.
Keep the cables at a safe distance from each other.. At a minimum, they should lie 50 mm apart if they are brought up to a brick wall. When laying to wooden structures, they are placed at intervals of 100 mm. The cable is passed through a hole created in the wall. It must be repaired using non-combustible materials. A cement or concrete mortar is suitable for this.
Following this, they move on to connecting cables to the electricity consumption control device. Here they are guided by the project. The key point is that as the site moves away from the power line supports at a distance of more than 25 m, additional poles will have to be erected. It is important to maintain the minimum height from the ground before entering the cable into the wall. This gap is 2.75 m. The height must be at least one and a half meters if the cable runs from the point of entry to the window.
The consequences of self-supplying electricity
It is not worthwhile to independently conduct electricity to a private house if there is no ready-made permit for such work. This concerns an increase in the power of the supplied power line or a device for monitoring the consumption of electricity. These actions are considered illegal and are subject to penalties. If illegal activity is detected, a special service will dismantle the control and distribution devices for the lines. The legislation even provides for the disconnection of the site and for this it sends its employees over the power grids.
If a house or plot was connected to electricity without the appropriate permission, it is difficult to make these works legal. Legalization in such cases requires more expenses than connection through a licensed organization.
Alternative options for summing
There are situations when a number of circumstances prevent the site from being connected to the power line. The solution to the problem can be the formation of autonomous sources of electricity. Let's say you can use solar collectors. When choosing such units, they look at the power of the energy consumed. If it is used only for domestic purposes, the 6 kW mark would be a suitable power level.
Here you need to look at the maximum amount of electricity that is available from March to October, and then - in sunny weather. As soon as cloudy days come, the amount of electricity generated will drop markedly. At night, the devices will function due to the available energy reserve in the battery. This is possible if it is brought to the solar system.
If you decide to opt for solar panels, you need to prepare for serious costs. They include the purchase of all components of the device, as well as the execution of work on their installation. On top of that, regular maintenance is also required. If you have the necessary experience and understand well how to conduct electricity to a site without using professional services, it is undesirable to do this without permission. In the future, this will lead to penalties. After that, they will also completely de-energize your site. It is better to use the services of design organizations that specialize in servicing power grids.
