How to connect electricity to a private house

Immediately after buying the site, the question arises about the supply of communications. First of all, it concerns electricity, since without light it is difficult to imagine construction and further operation of absolutely any home. Despite the seeming simplicity, this question requires a detailed consideration, otherwise there will be problems that will be difficult to eliminate.

Theoretical aspects of electricity connecting to a private house

In order to systematize the procedure, it is logical to make an action plan:

• formal stage
• load calculation,
• selection of components
• connection.

The formal stage includes the preparation of the necessary documents and obtaining permission in the relevant instances.

The load should be calculated in order to properly select the necessary components. Cable, protective devices, minissiformator and other elements differ in each other in the first place by physical properties, so high price does not guarantee high-quality power supply.

The connection process is also sufficiently important. Firstly, there are certain requirements for whose violation will have to pay a fine, secondly, the incorrect connection is fraught with unpleasant consequences.

Registration of documents for connecting electricity to a private house

If you connect electricity from a pillar, while not by collecting the necessary package of references and permissions, it will soon come out the check and makes it a penalty in the amount of 30,000 rubles. and more. Therefore, it should be started with a campaign to the appropriate RES.

To conclude an agreement, you will need:

• passport,
• certificate of ownership
• act of the survey of the site.

Depending on the region may require other references. The act of examination is a district engineer after examining the site and make sure that there are no signs of unauthorized connection of electricity.

If you need to connect electricity in the country, which is located in the country cooperative or village, you should clarify the procedure for paperwork at the local council or the Chairman of the Cooperative. In both cases, RES concludes a collective agreement with specific conditions for connecting consumers.

The presence of permission allows you to move directly to the connection of electricity. Since this work in most cases is required to make regular electricians, it is advisable to install a minissiformer on the site. Thus, the brigade will escape the transformer, install the counter. The remaining works are performed independently.

The benefit of such a way is to essential savings. The fact is that for laying cables and connecting the house, electricians of the RES will take a high fee. In addition, they will oblige to buy cable from them at an inflated price, while its quality will be far from the ideal.

In the case of transformer 380 V 220V, the electricians will be required to use high-quality cable. In addition, the personal transformer will reduce the voltage drops to a minimum and significantly increase the maximum permissible load.

Calculation of the load on the power supply

It is not enough to connect the house to electricity, you need to correctly calculate the amount of energy consumed. Otherwise, the constant shutdown of the light will become the norm. Although the standards set the power rate of 4.5 kW, this figure does not meet modern requests.

• washer,
• boiler,
• fridge,
• electric stove
• electrophovka,
• iron,
• electric kettle,
• vacuum cleaner,
• multicooker,
• blander,
• microwave.

This is a list of only the most powerful household appliances, the total load of which will be more than 15 kW. Naturally it is not assumed that all these devices will be included at the same time, but in practice, many of them have to be used in sharing.

Experts recommend to make a power supply of 10 kW. It is unrealistic to get permission to such a figure in RES, so you need to take a standard contract, and the wiring is already on the mind.

Accessories for connecting electricity to a private house

The main is the cable. When it is elected it is important to remember that aluminum is although cheaper, but in the entire parameter heavily inferior to copper. Therefore, for the house where it is planned to live constantly, it is better to immediately buy a copper cable.

Since the maximum power we chose at a level of 10 kW, the main cable that will go from the transformer to the camshaft must have a cross section of 6 mm. It is important to know that the cable laid openly has a higher bandwidth than the one that lies in the ground. Consequently, for laying in the pipe, you need to use a cable with a cross section of 8 mm.

Do not be afraid of the cost of this product, firstly, it takes only 10-20 m, secondly, it is still much cheaper than to change the entire wiring and buy new household appliances.

Next comes the most interesting part. According to technological requirements, a daiscuting automaton must stand before the counter. As a rule, it is put by electricians themselves, but it is not fixed to the seal. Therefore, it can be replaced independently. At a maximum load of 10 kW, the current in the wire reaches the value in 50 A. Standard automata goes to 16 A. It is necessary to replace their interior into the inside from the machine to 50 A. In this case, the externally, the corps will not differ, but inside the automatic in full Extent will suit the requests.

The meter is placed at the output current of 220 V. Therefore, the daunting machine is not allowed to deliver the required value. On the other hand, if it is spent on the counter, designed for 380 V, then the problem with the daiscutual automaton is solved by itself. A good option is the AP-50 circuit breakers.

Next you need to select a switchboard. The main criterion - he must protect the layout of negative environmental factors. Especially if the distributor is installed on the street. Plastic boxes are optimally suitable. Metal use is inappropriate due to corrosion exposure.

Next, you should install the accounts and connect the maternal cable. The number of automata is determined by the number of rooms plus a boiler and air conditioning if they are provided. Electrical installation also requires a separate machine. The principle of connecting each room to a separate machine allows you to easily distribute the load and the budget saves a certain way.

If we are talking about the kitchen, it is clear that there is a lion's share of electricity consumers. Consequently, you need to take the same cable with a cross section of 6 mm. For the rest, the cable with a cross section of 2.5 mm is suitable. Sometimes all the lights put on a separate machine. In practice, it is not convenient, since due to one light bulb, lighting will disappear throughout the house.

The capacity of the accounting machines is increased in the same way as it is done in the daisfactory.

How much is it worth connecting electricity to home

Making an overview of the value of various brigades there is no point in the meaning, as prices vary depending on the mood of the Prob. Therefore, we consider only objective investments:

• cable with a cross section of 6 mm - from 30 rubles. for 1 m.
• cable with a cross section of 2.5 mm - from 12 rubles. for 1 m.
• doodle automatic - from 300 rubles.
• accounts - from 90 rubles.
• distribution shield - from 600 rubles.
• the costs of paperwork - 1,000-3,000 rubles, the price is indicated for the possible nuances.

For approximate calculations, we use standard parameters:

• 6 mm cable need 20 m, cost 600 rubles,
• cable with a cross section of 2.5 mm need 45 m, cost 540 rub.,
• accounting machines 7 pcs, cost 270 rubles,
• total about 5,000 rubles.

Prices are on a product that is sold in the construction markets. When buying in a construction hypermarket, the cost will be slightly higher. In addition, not all rates make a problem from connecting new consumers, so this cost of expenses when luck goes.

How to connect electricity to home

Now let's go to the main one. The cable with a cross section of 6 mm or 8 mm refers to the power. It is desirable that he constitute three monolithic wires, land, phase and zero. This option is more expensive than the section of thin wiring, but it is more reliable. Connection order:

• make ends
• connect the wire to the meter,
• stretch an air or underground line, it should be remembered that the cable needs a support every 20 m.,
• pull or raise the cable to the distribution panel,
• connect it to the relay for automata.

If the relay does not fit with the switchboard, then it is necessary to buy it separately. It is important that it is calculated for the strength of current at 50 A and more.

Next are installed automata. They are connected directly to the relay. Less often, when regular electricians installed the counter directly in the distribution shield, the power cable is supplied to the meter, and the machines are connected from it. This uses a cable with a cross section of 2.5 mm.

Next is the preliminary layout of the cable. The maternal cable must serve all switches and outlets in the room. For remote lighting devices, you will need a cable with a cross section of 1 mm. Its cost is not large, so it does not affect the overall estimate.

After laying the cable, the air conditioner, boiler and electric power lines are displayed throughout the rooms. If there is still a free space on the meter, then put a spare machine and stretch it from it an additional line in a children's room or living room. Here, more often than other premises, there is an additional load on the power grid. The machine on the counter is turned off, and the cable is hidden in the distribution tray, which is closed with cardboard, and then either plastered or stuck with wallpaper. The location should be labeled.

Once all the wires are connected, a machenet machine is turned on. Modern meters are equipped with an indicator LED, which shows the presence of voltage in the network. If the light burns, then there is a light. Before turning on the accounting machines, you need to wait 1-2 minutes so that the current warms the cable and evenly distributed it.

Accounts are included in turn. At the time of inclusion, they create an increased load. Although it lasts only a few milice, at the same time the inclusion of all automata immediately will lead to a multiple increase in the load and disconnection or bravery.

After the first turn on, you must successively turn off each automatic and turn on again. This is done in order to check the serviceability of the mechanisms. Sometimes after the first switching on-off, the machine is either declined, or is turned on only after several attempts. This is an explicit evidence that it is defective and is subject to replacement.

After re-inclusion, the power grid is ready for operation. If the recommendations presented were observed, there will be no problems with wiring for 50-60 years.
