How to use a cable or conductor and use the cable
The quality of home repairs is the result of a careful approach and attention to detail, especially when working with electrical cables. This is not a very professional electrician, but it is difficult, even if the cable is instructed, and even crawled behind the cable to the apartment in a particular case. No matter how much time, you will recognize that the necessary information is not in the public space. Correctly elect a conductor for lighting or connection to an electric fireplace, and a guarantee for safe work on a domakinsky uredi.

Standard for installation in electrical equipment with installations from PUE. Tosi document defines the fee for installation and operation of electrical equipment. Poznavayki gi, you can sort out which conductor is kinder and crawl for the cabel to the apartment. The Electrical Installation Code (Chapter 2.1, Section 2, Part 3, Chapter 7) will provide a basic selection assessment for cable products.
In order to correctly rely on the conductor, it is important that you choose the characteristics and design of the cable. Whenever you buy a conductor, you can also guide from PUE, pages 2.1.13-2.1.66.
For the right choice for the conductor of the apartment, try and imate foresee:
- Determination on the parameters for the cable - the cross section, the material for the conductor and the design for the insulation on the cable are working perfectly. The straight section on the kernel is calculated according to the method described in chapter 1.3 on the PUE.
- According to the PUE request, Clause 2.1.31, “there is a requirement for the conditions of the surrounding environment, the purpose and the stability of the design, construction and architectural characteristics.” Tova means, what is chosen on the cable based on the conditions, with which the conductor works in the premises (housing and utilities).
- Type of cabling according to point 2.1.4 from PUE can be hidden, mobile or open. See the installation for the readings in Table 2.1.2. PUE 7. Details for the conditions for relying on a guide in the gradate are in chapter 7.1 of PUE 7.
Choose a cable for cable installation for an apartment, try and take a foreseeing examination for GOST 31565-2012 for fire safety, indicators for formation for smoke, separation for toxic gas. Crushed behold, what aluminiyat doprinasya for spreading it to the front on the mountain. In accordance with GOST, in Table 2, please change the options for cable usage depending on the type of design. For good cabling on the apartment, use cable products from type "ng (A) -LS".
According to the edition of SP 31-110-2003 "Electrical installations in residential and public buildings, rules for design and installation", it is cabled in residential premises and all the disturbances from bodies with copper conductors. For fire safety in the apartment, I used the very honey.
The selection for copper for hidden cables for cable is determined from the high conductivity on metal and the low resistance on the finished product. Cable from aluminum conductors with PVC insulation e-eutin. The line is not far from being crawled into honey, for some reason it may have been crawled for the cable on the electric fence in the fence and licked into the apartment.
Point 2.1.31 from the PUE to find out the guide to the conductor and it is distinguished by color: “Cabled for the trip and the opportunity for forest recognition by the length of the conductor by color.” Cable, used when cabled for apartments, trebva and all from a conductor with different color insulation. For zero, the conductor is a commercial conductor with a blue or yellow-green insulation. Other types of coloring on a twist on a sartsevinata, including black, cafyavo, red or white, mean the phases of the conductor.
For apartments or rooms and a sauna, using all-plastic or wooden cladding, tawani, wall cladding is made of PVC material, cables and methods for mounting on the wall are selected as open to protect the cable. Osventova, according to the standard for PUE (Clause 2.1.43, Clause 2.1.45) “Indoors and outdoors installations with a chemically active environment, all electrical elements must be wired for trebka in order to be resistant to the environment or protection from its effects.”
Tel or cable
And two types of conductors can be used for shortening on the cable to the apartment. All conductors consist of one or more conductors, maybe naked, without insulation, under varnish or in protective wrapping. Produced under the format on bodies with a naked cross-section or thins of bare lived in a single winding.
The cable is a product of the cato group from the isolation of the conductor. In a single wine product, two or more conductors are self-insulated. The whole set of conductors is sealed in a common wrapping.
For the apartment, they will protect the cable of the wine and the package from a slightly dense copper conductor in a double-layer insulation.By the way, in the case of a doorway, you can use a chain from a few niches with a cross section of 1.5 mm² in meca insulation, made of rubber, containing silicon or PVC with a braid.
There are a lot of retro cables, such as small part of the cabling in the apartment is ruled through usukvane on the SHVO 2×1.5 cable.
Behind the entrance and connected to electricity from the external shield of the housing estate is using a SIP-1 or SIP-2 conductor with aluminum conductors and polyethylene insulation.
Behind the covert cabling in the apartment is a copper cable with a slightly tight conductor, with its own insulation and double-layer sheathing.
Gamat from cable products, available for payment by the owner of the apartment, including over 300 marks. Most of the products are produced in a specialized, most industrial design. For the apartment, those sa are overheated powerful and not sa evtini. Zatova elect something in a simple way.
Characteristics on VVG cable
Whether you choose the right option for the cable, then the best solution for the price of a product on VVG or a licensed version on NYM. And two types of cables are designed for operating voltage from 0.66 kV and operate under standard conditions.
The VVG marking means that the conductors are made from honey, the letter “A” is abbreviated for aluminum. Two letters "B" show that the insulation on the vest and the wrapping are made from polyvinyl chloride, the letter "G" of the cable marker without armor.
Shielded cable construction
In the flock and for the cabal in the bedroom and day in the apartment, use VVGng-LS, for non-residential objects - VVGng.
NYM cables are licensed from the highest quality to the harshest, for the sake of some sa in Skype. These are different from VVGng itself with the presence of an additional layer of heat-resistant gum under a protective lining.
In addition to the VVGng, conductors from the Flame-X and N2XH brand can be used for electrical wiring in the apartment.
Behind the entrance and connected to electricity from the panel to the group under the apartment building is a two-pole automatic machine or electric meter using a SIP-1 or SIP-2 conductor with aluminum conductors and polyethylene insulation.
Cross section
Okabelavaneto in an apartment or a house is officially divided into two clones:
- Electrical conduit for consumers for electricity, connections through contacts or chanti, such as in the case of air conditioning, electric stoves, boilers.
- Line for lighting on the apartment. Consumers sa illuminator of the body with a low power, wired to the cable through the wall key.
Chapter 1.3 on PUE 7 providing a method for calculating the straight section on a cable. In practice, those tables are used for the stability of the straight section for a specific value for the tolerance of long-term current.
If you want to nest, one of the optional lines is from VVGng-3×2.5, VVG-LS 3×2.5 or NYM 3×2.5.
Some residential premises are heated by an electric boiler from a three-phase grid, but all of them are damaged and there is a separate line. For protection, choose a 3-core cable. Izvarshvame zero work conductor with separated conductor. The cross section of the vz is not ready to be chosen, based on a current of 1.7-1.8 five more, broken off in the phase.
The cable for lighting in the apartment is usually selected from the series VVGng 3×1.5, VVGng -LS 3×1.5 or NYM 3×1.5. It is welded into the electric wires on the lighting body at a low angle, chipped into a clone, stored on the cable, for some sufficient cross-section on the cable from 1.5 mm².
honey or aluminum
Aluminiumvoto kabelevane e in Euthino from copper.Therefore, with an obvious lack of aluminum, for example, the tendency to form pucnatini during oxidization, oxidizing on the surface on the conductor in the air, cables and conductors with aluminum conductors competes on a par with honey. The interior of the apartment is aluminium, all in comfortable conditions, with the exception of the sauna and the kitchen. Niskiat capacitance on the natovarvana on the aluminum forestry compensator through the use on the conductor with a straight cross-section on the conductor in the cable on the apartment. On the right side of the aluminum, it’s sad, so go for the purchase of products on the cables at a low price.
Kolko belly have a need
Election of the wire on the conductor, in general, on the goods, on the cable, on the apartments and on the phase, on the electric grid. For cabling in the apartment, use a 2- or 3-core cable. This is the same lighting line for the illuminators with a single lamp, then in the conductor there are two lived. For two-position polylines with many lamps for good lighting, you can use a 3-wire line.
Promyana in natovarvaneto, depending on the armor for nuclear
For connection to goods over 300 W, all cables are used with a little more than three lived, th kato electric uredi trebva and earth.
It is not possible to use the conductors cato ball screw and PVS
And in two cases, the conductor is a sheaf of stranded conductor, all of which is covered with PVC insulation. The top of the cable is a sheaf of se supposing an upholstery from plastic and mek polyvinyl chloride. The isolation is weakly localized on PVA and SHVVP. And two types of conductors are used for temporarily connected to the movement of electrically uredi. Accelerated stretching on PVC insulating winding lead up to paint on the belly on the cable.Usually cable manufacturers will put a 10-year operating limit on their certificates. Tova is not enough for a cabel to the apartment.
Ako will choose the conductor for the guard, togawa ShVVP and PVA are not a good solution. Goods are budget options for cable products, those are not intended for long-term operation of dory with goods from half of the allowable cost. So the cable is laid in a cable on the apartment, now it's flooded. Since debelin is painted on PVC, an accidental manufacturing defect on the insulation can lead to a connection to the cable and a fire.
The ShVVP cable may have been temporarily connected to a lighting fixture.
And two types, PVA and SHVVP, can and all use the same conductors for lighting in adjustable lamps, such a carrier for temporarily connecting the electric grid to the sechoary, fuel guns, emitters, manual electrical equipment for repairs in the apartment.
Conclusion
Nyama yes ima problems with the choice of cable for cable to the apartment, but do not occupy yourself with an independent activity and do not take the risk and bet for personal safety. Suffice it to know the norm and claim for cabling, refer to PUE7, SP31-110-2003 and GOST 31565-2012, or yes, trust the existing practice for using VVG and NYT cables when cabled on the apartment.
