Any construction or repair is necessaryvypolnyatkachestvenny wiring, because of this in the future depends not only safe and nadezhnayaekspluatatsiya appliances and electrical equipment, as well as life and health of you and the people around them.
We will tell you about the basic safety rules during the execution of electrical work with their hands, the methods and characteristics of wiring.
To date, there are several types of wiring:
- Internal wiring (internal wiring installation);
- installation of overhead lines (overhead lines);
- podklyuchenieelektropriborov: boiler, air conditioner, washing machine or oven;
- cable installation (cable) in the corrugation;
- Installation of the cable into the cable channel;
- cabling in Stroebe (installation of interior wiring), etc.
This article will discuss the main features when:
- Wiring with their hands in the house or apartment;
- Compliance with the requirements of SNIP and RB at the electrical work;
- Vyboretipa, brands and cable size for a specific task;
- Shtroblenie walls and installation of indoor / outdoor wiring.
To begin, we recommend you to read the video, which allow you to better understand the key moments in the performance of wiring installation with their own hands.
The main objective of montazhaprovodki own hands is to minimize the financial costs of maintaining the quality and reliability of electric communication.
Uglovoyshlifmashiny (Bulgarian) or wall chaser with household cleaner;
Voltage Meter (DMM);
- Quantity and power of home appliances;
- The number of sockets, switches;
- installation household appliances Places;
- Neobhodimogokolichestvo cable or wire;
- The quantities of circuit breakers with the calculation of power consumption;
- Positions where the electrical panel.
Any electrical installation begins with the installation of electrical distribution panel. There is 2 types of these devices:
Vnutrenniyraspredelitelny plate (mounted in a cut by using a grinder or the opening wall chaser appropriate size);
External or nakladnoyraspredelitelny plate (mounted by means of dowels or directly to the building wall nails or some other structure).
Before direct montazhomego in placeinstallation, you need to dial the interior. It is sufficient to determine the number of circuit breakers based izkolichestva rooms iihfunktsionalnogo prednaznacheniya.A well as the number of necessary equipment in it.
If you perform wiring in a wooden house or apartment, let's calculate the number of machines and their power of appointment:
- For apartments needed bipolar AB (circuit breaker) 25A input - 1pc, and private homes in which power is supplied from the 3-phase network - three-phase AB to 40A;
- 10A SPST AB illumination (dependingthe number of rooms, given the bathroom, toilet and other facilities). Since the lighting network potreblyaetmalenky current, efficient use of the machine 1-2 to connect the entire apartment or house;
- Single-pole 25A AB - a rate of one switch per room. They serve to protect the wiring, appliances and equipment from short-circuits.
- If you have smontirovanboyler, and it requires an additional two-pole AB 25A;
- To connect the electric needs one- or three-pole AB 40A, depending on its type.
As a result, you need poluchitsyavot such or similar electrical panel
After sborkielektricheskogoschitkaneobhodimovypolnit shtroblenie walls for wiring or installation cable cable channel or corrugation directly on the walls of the room, depending on your chosen method of electrical cable.
Grooves - a special ditch (grooves) in the wallcut through with a special tool (grinding machine or wall chaser with an industrial vacuum cleaner) in cases where the installation of hidden wiring needs any other communication (water, internet, telephone, sewerage, etc.).
If you are planning to sheathe the walls and ceilings with plasterboard, then shtroblenie walls are not required.
In such sluchayahneobhodimo perform wiring in boxes or panels with fastening on the wall with special clips.
Let's take a further look at how to perform a direct installation of electrical wiring in the house.
And since you have already decided on the number of outlets,switches and lamps. Next, you select the brand and the cross section kabelya.Chtob not talk for a long time, "how and why?", Say at once - the best option to use VVGng 3h2,5 mm2 cable (phase, zero and earth) to connect the sockets and appliances, fixtures kabelVVGng 3x1.5 mm2dlyapodklyucheniya and switches and VVG VVG 3x4 or 5x4 cable for connecting the electric furnace (depending on the number of phases).
To start stretch cable (wire) in the corrugations, and then using special clips fasten it to the walls of a wooden house or apartment.
As a result, one end of the wiring in the ripple will be at the points where you want to connect, and the second - in the place of installation of the electric panel.
Very often "amateur electricians' connect wiring using twists. This is a gross error and a violation of all electrical safety rules.
In such cases there is a heating and oxidation kontaktov.V resulting in the best case just otgorayut wires, and at worst - there is a fire or a fire.
Previously, high-quality wiring using a soldering iron and tin solder, but now-special clamps.
They provide good contact and sealing contact connections. However, they can be soedinyattolko wire with a small cross section. (10 mm2).
If the need to connect the cable with a 10 mm diameter2 above, special hermetic coupling calculated voltage 0.4 kV to be applied (220 - 380).
They provide a perfect contact, fully protect the junction from moisture and serve for decades.
Features Wiring with their hands in the bathroom ↑
- It prohibited the distribution and installation of junction boxes;
- Do not install the sockets and switches near sinks or other water sources;
- To protect people against electric shock in the electrical panel must be mounted RCD (protective device off;
- All equipment must be grounded!
Since 90% of the apartments since the Soviet Union is notground, it is necessary to lay yourself. To do this, mount the additional cable (for example, 1x4 PV3) from the main electrical panel in the common corridor to the bathroom komnaty.Est also another barbaric method - to score in the wall iron pin with a diameter of 10 mm to a depth of 1 meter. This can be done only if in your house concrete walls.
- To highlight the need to use safenapryazhenie.Konechno 90% of the item is not met and the lighting is powered from a stationary 220V.Dlya AC power supply to eliminate the infringement must be completely remodel the bathroom circuit power and installed outdoors down transformer 220 / 12V.
Depending on your region, the pricing may differ significantly. So to answer specifically to the question "what is the cost of installation of wiring" in a private home will not work.
Some experts believe based on the number of points, and other footage from the method of laying the wiring, and others take the numbers from the ceiling ...
Well, for example, a full installation of electrical wiring in an average-key will cost:
- For a studio apartment - 5 000 rubles;
- For one-bedroom apartment 40 m2 - about 8000 rubles;
- For one-bedroom apartments up to 60 m2 - about 10 000 rubles;
- For 3-bedroom with an area of up to 72 m2 - about 15 000 rubles.
If you are interested in prices for wiring in a private home, there is still more complicated and each private electrical wiring or organization has its own price.
