Putting electricity into the house. Recommendations made.

As is known, modern home is unthinkable without the use of electricity. This is not surprising. After all, comfort in your home starts with a proper connection to the grid!

In addition to the nutrition of all household appliances, at the expense of the electricity works most of the engineering systems of your home. That is why the question I electricity in home It requires a thoughtful and responsible approach, and any mistake at this stage may subsequently result in additional material costs.

Based on the experience of participants FORUMHOUSE and comments of experts in this article we describe:

• The fact that first of all needs to be done before entering the electricity in the house;
• About how way to properly do the electricity input into the house;
• On cable assembly features when entering the electricity in the house.

Once the owner of the suburban housing receives at the hands of the technical conditions for connection to the power supply network, the main question arises before him: how to make electricity input into the house.

To do this, the process of connecting to the mains should be divided into several successive stages:

The decision of the administrative and legal issues

For the organization of the power house it is first necessary to make the project. If the landlord does not want to bear the costs of the design, then sooner or later he will face problems an administrative nature, or that the most dangerous problems with its fire and electrical safety installation.

To bring electricity to the home, it is important to remember that:

• Any electrical installation must be coordinated at the local Energonadzor, electricity or with the management company dedicated to the exploitation of local electric networks;
• To obtain permission to join the power necessary to make the development of pre-project and then the project itself;
• Incorrect connection to the power grid property owner can get penalties.

power projecthouses- a technical documentation, which contains all the information regarding the location of wiring, electrical equipment and lighting in the home, as well as characteristics of materials, circuit electroboards plans wiring harness and placing electrical load, the specification of materials used and equipment.

Technical specifications (TU)- a document that requires the owner of the house to complete the project, agree on it in all instances specified in the specification, perform a number of other - necessary, according to the organization issuing the specifications, the technical construction of administrative actions character. Performing TU entitlespermissionto the power connection for the required allocated power homeowners. Also, the document includes a list of all technical specifications of electrical work and power connections.

We expect section of the cable is needed to enter the house 

It is up to the smallest detail to rewrite all electrical power, which will work on the network, including the light bulbs and the expected load that you will be connecting to the electrical outlet. Particular attention should be paid to the special loads - are motors and pumps. Since they have the starting current, in the future too, it will have to be taken into account.

Now we have a total capacity of around the house, including all anticipated loads. After that, it is necessary that the total power supply multiplied by the coefficient for the calculation of which is convenience and in case if the homeowner forgets to take into account any load can be equated to the unit.

Then you need to watch table «Long permissible cable currents. " Using it, we find the currents that can withstand the cable or wire. You want us to talk, we get a simple division of the total power for voltage 220V. For 380V networks need to share power at 380V and the square root of 3.

Now that we know the current that goes to input cable.

Once we have learned the load current, you can choose how to make the cable entry into the house. But first you must decide on the method of electricity input.

How is the input Electricity in house 

There are three ways to connect your home to the power line:

• Cable entry of air;
• Cable gland under the ground;
• Wire entry into the house through the air.

Electrical connections by air is the easiest and least expensive way to connect your home to the power grid. Of the minuses can be noted that stretched through the air lead-in cable into the private house can spoil the aesthetics of the site.

To a definite plus underground cable entry into the house may include increased immunity to cable breakage, as well as its greater fire resistance.

Cable selection for the input of electricity into the house

That's the first thing you need to know the developer, choosing to enter the electricity cable in the house.

Elena Bragin:

- The first thing to imagine that such a cable and how it differs from the wire. Since each of these products has its own field of application, it is not necessary to experiment on themselves and their loved ones. If there is a possibility of frequent flooding and the possibility that the cable will be a lot of time to spend in the water, in this case, it is better to use specially designed for such conditions the product - from insulation silanolnosshitogo polyethylene.

The wire - is one or more conductive wires twisted together, each of which has its own isolation. Wires often have common protective sheath that serves to protect against various unfavorable external factors. Such as - high humidity, chemically active medium, mechanical damage, etc... These wires are called protected (PVA PuVV).

cable is one or more conductors enclosed in a protective shell. Usually it consists of one, and often several conductors, each of which has its own insulation, the wires are placed in a common shell. Can have a variety of additional components: the screen, armor and so on.

When you enter a house in electricity through the air better to use SIP brand wire. Since the insulation of the wire is made of a light-stabilized crosslinked polyethylene, this type of wire characterized by high resistance to UV radiation, which is very important especially when operating in the open air.

When laying lines in land should be used armored power cables (VBShv). Armor in cable design is protective against mechanical damage.

But we must note that the cable sheath is made of PVC, which is not resistant to UV radiation, which means that the cable at the exit to the surface of the earth must be additional protection.

SIP - it is self-supporting insulated wire.

Cable entry to the house should sootvetsvovat a number of characteristics:

Regulatory framework: cable wiring brand VVGng (A) -LS manufactured according to the specifications, which must necessarily comply with GOST. Such data can be found on the label to the products, certificates, etc .;

• Certificate for the products. increased fire safety cables -ng ng (A) -LS etc. subject to mandatory certification, including the fire safety system;
• cable design. Power cables made according to the standard must have a round shape and filling;
• Labeling - the cable must necessarily be present the following inscriptions: a brand name or manufacturer code and the year of its release.
• the manufacturer's reputation.

Mounting and cable entry into the house

How to make electricity in the house

One of the key requirements for cable entry into the house, you can call the following factors: - the opening cable must not be inside the house transits. Introductory shield must be placed in close proximity to the cable entry into the house. the entry itself should be done in a metal sleeve, it is necessary to drill a hole in the wall, insert the tube, and already inside the pipe to hold the cable. (Right - to connect the input power circuit into the house through the wall).

All the space in the tube remaining after cabling must be to score easily punched grout. Usually used for this purpose tow, soaked in the slurry.

Underground electricity input into the house

If the cable comes in the ground, then mount it on the house, of course, it is not necessary, since it takes place in the foundation.

Underground cable entry must be performed in a trench depth greater than 0.7 m. In the ground.

If you use a cable, not self-supporting wire, suspend it without the rope is prohibited!

The cable is attached to the wall of the house overhead brackets.

It is important to remember that the cable part that comes from the earth and goes on a pole or wall of the house, it is imperative to protect against mechanical damage. To do this, it is best to use a metal pipe up to two meters.

If the suspension cable is a cable, the cable for attachment to the wall should be installed eyebolt. It is important to remember that the cable for the whole length of the cable and the transition from the cable to the wall, and when you enter the house must have an appreciable slack. Before entering into the hole in the wall of the cable must loop below the hole. This is to ensure that rain water does not leak through the cable into the house. The very same cable must not be tightened. Since there are variations in temperature - the coefficients of expansion and contraction of the cable and at different rope. Therefore, when attaching the cable to the cable it should have a free play on the rope.

If input is carried out by means of cable, it is switched directly on the opening machine or a cutout in an aqueous shield. If you are using insulated SIW or bare wire to enter the electricity in the house, it is necessary to make switching to cable, SIPA is also necessary to use a special fixture. For bare wire used junction clutching, called by the people "nutlets".
