Standardized electrical wiring for a private booth. Entrance and separate outbuildings. Rope cable laying

⁰

Electricity is one of the main energy sources in all the different countries. It is important to find out what will become a house with the bags, where hundreds of people live at once, or to bring in thousands of people, as the power supply will be destroyed. The impossibility of the viscount is simple housework, cook food, spend your free time in comfort - the whole primary way of life will be just ruining. To the very same, the electric supply of a bagatokvartirny residential house is even more important and more important.

Scheme of electrical supply of any objects

Categories of electrical supply

To better understand the power supply circuits bagatotop booth(like a living thing, so be it any other), it is necessary to know what electrical supply can be carried out different ways, which are strongly challenged for superiority. The most recent category of superficiality is the first. Behind it, living houses are powered by two cables. Skin of them is connected to an okremy transformer.

If only one transformer or a cable is viide from the fret, an AVR (automatically boosted reserve) is attached to immediately bridge all the power to the working cable. Zavdyaki tsomu problems with the supply of electricity will be delayed for a second. After the group of electricians arrived and the property was repaired, which went well, the supply of electricity is carried out in the normal mode.

For the first category of reliability, electric supply of heating points is carried out at rich apartment booths, as well as elevators. Sound this category of reliability to be chosen during the electric supply, de one hour over two thousand errors, sloping buds and operating rooms at the librarians.

The other category of superiority has a similarity to the first. At the same time, the wake is also powered by a large number of cables, leather from some may be a power transformer. However, at the time of the release, the control of the fret is not automatically, but manually. Rob the chain staff. Through the whole electrician, you can’t give in to the slow-witted dekіlkoh whvilin.

This model of electrical supply is selected for living quarters over 5 surfaces, provided with gas stoves.

In addition, the category includes booths, which consist of 9 apartments and more, equipped with electric stoves.

Usі booths of another category of electricity supply can be divided into two groups. The booths of both groups are provided with two transformers and two with live cables. Ale, in one mode in the normal mode, the need is equally divided between two transformers.

Under the hour of the accident, all the saving electric power is switched over to one transformer, the fahivtsi docks do not cause a breakdown. In the other case, in the normal mode, energy is supplied through one transformer. Whenever there is an accident, the voltage is immediately transferred to another transformer - a reserve one.

I nareshti, the third category of electricity supply - the simplest. At the living room, it is powered by a type of transformer for the help of one single cable. There is simply no backup option. Through ce, in case of accidents, the disruption of the supply of electricity to the houses can sometimes last up to 24 years. For this, make sure your mother has a spare option.

New needs for electricity supply projects

Regardless of the selected category of electrical supply, you can proceed to installation only after the completed electrical supply project has been completed. Deyakі people really do not understand, now it's necessary. And more often than not, the project needs a little more money, and the service itself is even more expensive. And yet, it is impossible to start a robot without a finished project.

Firstly, the most foldable project allows the robot to carry out the work quickly and without teeth for clarification of data, the choice of material and the carrying out of folding pods.

ready-made project for the electric supply of a booth

While the project is ready in hand, the installers can quickly get to know all the systems, and take care of their work without worrying about any third party. For this reason, the installation of the power supply system takes at least an hour.

In a different way, it’s possible in the future to carry out electrical wiring repairs (and fakhіvtsі recommend working at least once for 20-25 years), it’s a report to allow you to easily see the whole work – request fakhіvtsі, having seen the plan from the papers, you can look at the future, . loss of walls when replacing wiring.

Tse allows you to save not only an hour, but pennies, as they are stained during a major overhaul.

Thirdly, as may be a serious accident, due to poor wiring in the residential, office and administrative life, the electrician is sufficient to carry out the project, to understand, de-route the keys of the university, and to change the system. Therefore, it will take at least an hour for repairs.

3. ORGANIZATION AND TECHNOLOGY VICONANNYA ROBOT

3.1. Substantiated for the beginning of work on the installation of the electrical supply system, whether it be budіvlі є Act of technical readiness before installation. Before the act of acceptance, add the geodetic schemes with the applied openings, openings, channels and other elements for laying the electrical supply lines.

3.2. Furrows, empty, canals, niches, open in the walls and inter-overhead overlaps, necessary for the installation of electrical wiring and wires, due to transfer in the wake-up chairs and viconan break-in organization in the process of life.

3.3. First, proceed to the assembly work, it is necessary to carry out pre-preparation work: rozmіchuvalnі, zagotovelnі and punching work. Prior to the beginning of the installation of the electrical wiring, the next step is to designate the place for introducing cables at the booths, as well as the place for installing electrical equipment (electrical appliances), vimics, plug sockets, electrical boxes, and lamps. After the installation of the electrical installation, the lines (lines) of the laying of electrical wires are immediately marked. Let's designate the place of the installation of a rose shield. As a rule, yoga is installed close to the entrance to the house or apartment, in the opalous accommodation, at a height of 1.5-1.7 m from the logs.

3.4. Before the beginning of the installation work on the objects of the guilty, come in:

- otrimano design-koshtorisnu documentation;

- uzgodzhenno graphics postachannya obladnannya, vrobіv and materials with improved technological sequence vikonannya robit;

- the necessary accommodation was taken for the placement of teams of robot workers, engineering and technical workers, manufacturing base, as well as for the storage of materials and tools for safe entry to the protection of work, anti-burn care that protect the navkolishny middle;

- priymannya for the act of budіvelnoї part of the object for the installation of electrical lighting.

3.5. For the distribution of the transferred documents, it is necessary to submit only to the organization, in order to be able to confirm that similar work has been carried out. The supervision of the installation work itself is also the responsibility of carrying out only fahivtsі, as it may already be necessary for the installation of electrical lighting structures and that obladnannya. When creating an electric lighting project, it is necessary to protect all areas of the electric power supply, such as the efficiency of navigation, temperature operating modes, and the impact of moisture on the work of lighting and other electric devices. At the design stage, the possibility of controlling the electric lighting system is also thought out, the necessary equipment is selected, and low-current control lines are designed (Fig. 1).

3.6. Electric installation robots are built at two stages.

At the first stage, in the middle of the future, work is carried out on the installation of structures for lighting fixtures, cables, installation of steel and plastic pipes for electrical wiring, laying of wires attached holding to plastering and finishing works. The robots of the first stage should be victorious in wake-up calls and disputes for the confusion of the schedule at once with the variability of the main weekly work, with whom you are guilty built-in structures and the laying of pipes due to breakdowns and obstruction.

At another stage, work is being done on the installation of lighting fixtures, laying cables and wires, and connecting cables and wires to fixtures. В електротехнічних приміщеннях об'єктів роботи другої стадії виконуються після завершення комплексу загальнобудівельних та оздоблювальних робіт та після закінчення робіт з монтажу сантехнічних пристроїв, а в інших приміщеннях та зонах – після встановлення обладнання та інших електроприймачів, монтажу технологічних, санітарно-технічних трубопроводів.

3.7. The choice of materials is delivered according to the schedule of the electrical installation organization, which may transfer the first supply of materials and types, included to the specifications for the blocks, which are prepared at the warehouse and assembly facilities of the electrical installation organization. Upon acceptance of the possession, lighting fixtures at the installation, an inspection, re-verification of completeness (without disassembly), re-verification of the visibility and term of the guarantees of undertakings-manufacturers are carried out.

3.8. Modern and industrial wires are attached, which are installed at special channels of expansion and installation during the preparation of future structures at the plant of concrete castings. If nothing else, then a wiring for socket boxes, vimics, sockets at the necessary places and with the improvement of the rules of the PUE is carried out, tobto. s dotrimannyam vіd vіdlogi (for vimikach 15 m). The place of installation of heating lamps, entrance shields, apartment shields, entrance shield is planned to be installed, it is necessary to install punching robots (for example, the passage of wires through the wall), opening in the panel on the stele for the installation of wires with a heating lamp or a chandelier.

It is shown in the middle of the rozpodilnymi boxes, apartment and introductory shields, in the pink boxes to vimikachiv. Rozm_tku vygotovlyayut on p_stav_ bud_velnykh armchair.

Fig.2. Marking the place of installation of the lamp:

1 - point of crossing the diagonals on the bed of the stone; 2 - temple; 3 - pole for transferring the point of installation of the lamp on the stele

Carrying out roaming work for electrical wiring starts from laying the path of the main bundle of wires, gauging the new one, turning the corners and passing through the cracked wall. In case of obov'yazkovo, the rule is that the darts on the wall are rolled either horizontally or vertically. Lay the horizontal electric wiring boards on 20 cm from the stele, parallel to the line of the stele and the walls (to reduce the mechanical fluctuation of the electrical wiring). When turning the electrical wiring route, the turn may be 90 °. It is possible to distinguish the places of anchorage of conductors from the extreme points of anchorage. Ale, along the mid-surface or mountainous crossroads, pierce the shortest path through the top of the box until the installation of the stele lamp. When applied rozmіtki vіdkritu that attached electrical wiring you can twist the rose cord. For whom farbuyemo yogo creid, vugill, blue. After that, we close one of the yogo ends, and the other end is pulled with one hand parallel to the wall or the steel. With the other hand, we pull the cord through the rosemary surface and sharply throw yoga. Hitting the surface, the cord is stuck on it, a clear straight line. In this rank, you can mark the place for fixing darts to the wall or steel.

3.9. Penetrating robots are beaten for the obviousness of the mark. The vibrators can vibrate the punches with a vibrator. The vibrator shakes the opening at the walls, at which darts are laid. Pipes ensure the possibility of changing the wiring. Preparing the opening of the lighting fittings and the installation of vimikachiv and sockets is also carried out after the auxiliary vibrator. In parallel, punching of furrows and fixing in them to the pipeline, preparation of new shields are carried out.

3.10. Creeper robots. After harvesting robots, darts are laid at the furrow and they are attached with staples, clamps insulation material and on the walls they freeze them with alabaster. Installation of vimikachiv, sockets vykonuetsya at special niches, they are frozen with alabaster. Shields are fastened with dowels. Plants produce various mounting details and fasteners: dowels, staples, bolts, pins. The kapron dowel represents a kapron bushing with two late cuts. Utrimuetsya in the opening for the opening of the fact that when the screw is screwed in, the walls of the dowel are wedged into the opening. The dowel-flowers are fixed behind the help of pyrotechnical equipment. The dowels from the old cuts are hammered in for the help of a bud-assembly gun. Scobie zastosovuyut for fixing the cable.

3.11. Wiring Laying of wires or ready-made wiring harnesses, fastening of wires and cables, tightening at the passage of the pipe. With whom it is necessary to vrakhovuvati, to dart to sockets, vimikachiv thinly. small required repair stock. Vіdgaluzhennya that z'єdnannya vykonuyutsya only at the boxes or on the contacts of sockets and vimikachiv. Opіr_izoljatsiї novozmontovanih electrical wiring may be not less than 0.5 m ZM. The wiring is to be wired with the necessary cut and insulation, it is to be satisfied with the standards of the PUE.

In good boxes (small. 3) it is necessary to take care of additional zvaryuvannya, and then insulate the city with insulating caps. For lighting in apartments with a vicorist, wire VVG 3 1.5 m, and for sockets wire VVG 3 2.5 m. by-button technology additionally for the kitchen, I’ll fix the wiring (for an automatic machine) with a larger tight band to the wire VVG 3 2.5 m or wind 3 4 m.

Fig.3. Starry look happy boxes

At the places where conductors are introduced, bushings made of insulating materials are installed near the box. Replacement bushings often vikoristovuyut pieces of polyvinylchloride tube. In applications with low water content, it is possible to install wires near the niches of walls and overlaps, or near the voids of overlaps. The walls of the nests should be smooth, and the lids should be made of fire-fighting material.

3.12. Zalezhno vіd vіd vykonanny vimikaі and plug sockets buvayut v_dkritoy and prihovanny vikonannya. For the installation of sockets and vimikachiv vіdkritoy vikonannya vіkoristovuyutsya vіkorosetniki. The stench is made from non-conductive material (wood, textolite, getinaks, orgsklo, etc.) and is produced from discs with a diameter of 60-70 mm, a thickness of at least 10 mm. Sockets close to the wall with screws or self-tapping screws with a countersunk head or with additional glue BMK-5 or KNE-2/60. When installing pіdrozetnikіv on tseglanyh or concrete walls їh zakriplyuyut behind the help of screws, the back of the hole is drilled at the wall, and the dowel is installed or a wooden cork. When vikoristanni combustible bases, I recommend mounting the sockets of the lining with asbestos with a thickness of 2-3 mm. Sockets or vimikachi are fixed on the socket box with two screws from a round head. Vimikachi, as a rule, is installed at the opening of the phase door. Tse nestrumlyuє elektrobezpechne vykonannya robit when replacing lamps and cartridges. To restore respect, so that the illumination was increased when pressing on the upper part of the key, or the upper button of the vimikacha. For wired wiring, vicorous wires and sockets for wired installation. They are mounted in metal or plastic installation boxes type U-196, KP-1.2. Їx dimensions do not change 70 mm in diameter and 40 mm in height. Boxes are installed at special openings near the wall and are smeared with alabaster roses.

3.13. Luminaires with fluorescent lamps are due to be handed over by the "Zamovnik" to the installation at the reference station and turned over to the light effect. Fastening of the luminaire to the supporting surface (construction) can be chosen. Luminaries, which are stuck in installations that are weak to vibration and shock, are due to be installed from stuck outbuildings, which are depreciated (Fig. 4 and Fig. 5).

Fig.4. Zagalny look lamps, which are installed in the premises, that posture wakes up

Fig.5. Installation of lamps and wall lamps on a daily basis

The arrival of luminaires to the group framing can be done for additional terminal blocks, which will secure the arrival of both the middle ones and aluminum darts with a crossbar up to 4 mm. Kіntsі wires, scho to come to lamps, lichilnіv, avtomatіv, shields and electrical installations, due to the mother, the reserve for a long time, sufficient for re-admission at different shaving.

The introduction of wires and cables at the luminaire and electrical installations at the same time as installations are due to the strengthening for protection from the penetration of the pilot. Electrical installations in case of installation at the most common applications, they must be laid in a special casing or box.

Vinikla Pardon

Payment is not completed through a technical pardon, costs for your account
were not written off. Try to get a sprat of fluff and repeat the payment again.

In order to correctly understand the difference schemes of electrical supply of living houses, it is necessary to know about the three categories of security of supply of electrical installations. The simplest category is the third. There is a transfer of livelihood of a living house from a transformer substation near one electric cable. If so, in case of an emergency situation, a break in the electric station can be less for 1 doba.

In case of another category of power supply, the living booths are equipped with two cables connected to different transformers. At the same time, when one cable or transformer is out of tune, an electric supply booth for an hour will be fixed for a malfunction after the help of one cable. A break in the electricity supply is allowed for an hour, necessary for the electrical personnel for connecting the entire booth to the right cable.

Є two different types of eating house with two different transformers. Otherwise, the booth is equally divided between both transformers, and the emergency mode is connected to one, or in the working mode, one cable is connected, and the other is reserved. Ale, in any case, cables are connected to different transformers. Yakscho in switchboard booths two cables were laid, one of which is redundant, and if it is possible to connect these cables only to one substation transformer, then maybe only the third category of reliability.

With the first category of power supply, the living booths are powered by two cables, as well as for another category. Ale, when exiting from the fret of the cable, or the transformer for the entire booth, they are connected to the working cable behind the auxiliary extension of the automatic switching on of the reserve (ATS).

There is a special group of electrical supplies (, systems of dimovallennya for an hour later, evacuation lighting and other days), so that you must be charged for the first category of dependability. For which vicorist there is a backup power supply. rechargeable batteries and small power stations.

For іsnuyuchimi standards for the third category of nadіynostі zdіsnyuyut elektropostachannya booths with gas stoves with a height of not more than 5 tops, booths with electric stoves from the number of apartments in the booth less than 9 and the booths of gardening comrades.

Electric supply for another category of reliability is provided by booths with gas stoves with a height of over 5, and booths with electric stoves with a number of apartments over 8.

For the first category of reliability, in the obov'yazykovym order, electric power supply of thermal points is required. rich apartment houses, at deyaki budinkah that lift. It should be noted that the first category is mainly responsible for the supply of electric power to some public health services: there will be more than 2,000 people working for over 2,000 osіb, operational and pologіnі vіddіlennya likaren just.

The small picture shows a diagram of the electrical supply of a chotyrokh pod'ezny booth, powered by a different category of reliability with a backup cable. The switching of cables of life is carried out by a reversible knife switch, which can be set to “1”, “0” and “2”. At position "0" the cables are connected. Vіd avtomatichnyh vimikaіv QF1 ... QF4 energize lines, yak_ go on pіd'їznim vertical risers, vіd yah kharchuvannya taken to the apartment. Zagalno budinkovі vantazhennya: illuminating descents, podvalіv, luminaires over the entrance doors, let's live a healthy group, to avenge our appearance of electricity.

Rice. 1. Scheme of electrical supply bungalow

Fallow in the number of apartments near the booth, all electrical equipment can be placed in one electric cabinet, and in a room. How the electrical installation of electric switchboard hutches looks, is shown in the photographs. On photo 1 - the entrance to the outbuilding and the building of the appearance. Photo 2 shows a reversing knife switch with guards. On photo 3 - automatic vimikachi on the lines that come in.

Yakby at the school subject: “Foundations of the electrical supply of our booth”, then accidents caused by the out of tune of different power switches and switches on power lines and at transformer substations, were trodden more quickly. We are grafted by children with our hands in front of them to tell them how to cross the road correctly. And if nobody reads us, as soon as the light went out in the apartment, then it was negligent to turn on all the electric appliances: cleaning, heating and electric stoves.

For example, if you turn on the wire, after the burnout of the breaker into the electric switchboard, then for the renewal of the electric supply, the electricians need to turn off the switch, replace the switch and turn on the switch again. The term "life" of all switching devices it is more likely to lie heavily due to the magnitude of the commutated vanishing.

Yakby all the bagmen's booths turned on their electrical appliances in the wire when the voltage was known, so the inclusions would be used with significantly smaller strumas and the knife switches would serve more richly.

In our butt, if the electricians switch off the switch, then in the lances of two phases with unburned guards at the time of opening the contacts, it is possible to make a crooked sleeping - for a fraction of a second and a sleeping arc, as a result, the contacts burn step by step.

Zmist:

In the middle of the energy sector, yakі actively vykoristovuyutsya all rozvinenimi kraїnam, elektrika occupies one of the leading places. especially important meaning electric strum nabuvaє near modern rich apartment houses, where hundreds or even thousands of people live. A short-term disruption in the supply of electricity can cause serious negative consequences. At the connection with the electrical supply of a bagatokvartirny booth, it can be superfluous and yakіsnim, which ensures uninterrupted supply of electricity to the skin. Tse food opratsovuєtsya at the design stage that warehouse electrical installation robots.

Categories of reliability of electrical supply

AT bagatopoverkhovy booths different schemes of electric power supply are victorious, which are brought together by a level of superiority and ways of supplying electricity to residents. The first category of reliability is considered to be the most foldable and transferring the connection of a living house to a double room cable lines, powered by other transformers When the cable is out of tune, or one of the transformers is connected to the same place, it will switch all the strains to the working line. To that, the supply of electricity will be pinned down literally for a few seconds. After the event repair robots, the electricity is again supplied to the emergency mode.

For the first category of electricity, elevators and heating stations are supplied for large apartment houses. Such a category of electricity supply itself is chosen for life, at which one hour over 2,000 people are staying. Here, they spend the sloping booths and the operating rooms at the liquor stores. Tse naiskladnіsha scheme of electrical supply of a bagatokvartirny housing booth.

Another category for the next few parameters guess the first. In this way, life will be connected to two cables that are connected to the power transformers. However, it is possible to get out of tune, switching to the working line by the devil's staff, and not automatically, like in the first category. As a result, the power supply to the survivors may be interrupted for a short hour. The Danish version of the electric power supply is installed in living booths with a height of over five tops, equipped with gas stoves. There are also nine apartments and more, in which there are electric stoves.

Usі ob'єkti, like under another category, mentally subdivided into two groups. The skin of them has two transformers and two live cables. At the first turn, under the hour of work at the regular mode, vikonano equally underlined the navantazhen between both transformers. At the time of an emergency situation, it is necessary to switch all the spares in one transformer, to the point of failure. Another option is to transfer less than one transformer, and in case of an accident, the voltage supply is switched to the backup transformer.

The most simple category of electrical supply is the third one, if the life of a living house is connected to a single cable and a transformer. And here is the backup option for the next day. As a result, at emergency situations, the supply of electricity is connected for 24 years. Therefore, it is recommended to think ahead. The third category of superficiality includes booths, less than 5 overheads, and installed in apartments gas stoves. Here, there are houses with a number of apartments 5 and less with installed electric stoves. The third category of electricity supply includes budinki, roztashovani in gardening partnerships.

Newly needed project

Electrical installation work can be done only after the completion of the electrical supply project. Project documentation is compiled at any time, regardless of the category of reliability.

At the link with a high quality of an individual project, which is designed for a specific future, the deacons of life are important for better victoriousness, and they are ready to make a decision, which is the most suitable for that other object. Tse allows you to save a significant sum - from a few dozen to a few hundreds of thousands of karbovantsiv. However, such an economy in a serious everyday life is absolutely unacceptable, the shards of all the houses are awakened one by one with powerful individual signs. The specialists of our company give a new list of services and explain the need to overcome the quiet of others.

The main achievements of the project are:

This project will significantly speed up the work, shards in the new order, all the constructions and the selected necessary materials were written.
We are preparing a project for installers to better understand all the systems of electrical supply and give all the respect to only their own robots.
In the future, during the repair of electrical wiring, a report scheme, which is added to the project, will give the opportunity to quickly, and even vikonatically, the necessary work. Fahіvtsі companies after the advancement of the plan of electric supply can carry out work with minimal damage to the walls and other structural elements.
In times of accidents caused by faulty wires, it is easy for an electrician to help the project to designate the key nodes that will change us beforehand. Tse znovu still allow me to reduce the hour of repair.

The project of obov'yazkovo insures the presence of electric and gas stoves. In every significant world, there is a stale supply of electricity. Fahіvtsі kompanії obov'yazkovo take up to respect the geographical position of the object, the quality of the insulation and the practicality of the scorching system. Incorrect wiring can lead to overheating of that electrical wiring. In this rank, without a detailed project, it is impossible to supply electricity normally to a rich apartment dwelling booth.

To this, all rozrahunka, especially associated with the most prominent and peaking ambitions on electric mesh, blame less. Only stinks can grow the most optimal choice Materials and possessions to put together a project that will help you to supply the coristuvachs of a richly overlaid booth.

Connection of a bagatokvartirny booth to the merezhі

The connection of a rich apartment house to the central barrier is often connected with singing difficulties, mainly through great expenses hour. That is why the deputies are sent to our organization, in order to make it easier to speed up the process of supplying electric power to the houses.

Fahіvtsі companies vykonayut all the necessary work, which consists of a number of steps:

Otrimannya technical minds in the organization, which vikonuetsya pіklyuchennya that far away maintenance of electric lines.
On the basis of technical minds, the design documentation for the electric supply booth is being developed. When tsimu dotrimuyutsya rules, vstanovlenyh chinnym legislature.
Dali prepared a project of electricity supply to be approved by the regulatory authorities.
When the weather permits, the development of working documentation with a detailed description of all the main provisions laid down by the project will be carried out.
Then a working project and other documentation is also requested from the controlling organizations.

If so, the project itself and the working documentation can be drafted for direct electrification of a bagatokvartirny booth. Behind the manager's office, all necessary electrical work can be done by the company's facsimiles. After the completion of the installation and connection, all necessary revisions of the systems’ practicality and the correctness of their connection are checked. For subbags of revisions and testing, acts and other documentation are compiled. Then, the power supply system can be operated without borders at the boundaries of the installed tightness.

Schob rozbiratsya in the schemes of electrical supply of living houses, it is necessary for the mother to be declared about the category of security of supply of electrical supply of electrical installations. Tsya іnformatsija camp in good luck, if you need a terminovy vykup nerukhomosti that apartments. There are only three categories of security for reliability.

The first category of reliability of electrical supply transfers the presence of two cables, when a transformer goes out of tune, the entire booth will switch to another cable, which works. Tse zdіysnyuєtsya for the help of an automatic attachment to the reserve (AVR).

The first category of reliability is responsible for energizing the system of dimovidallennia for an hour later, evacuation lighting, fire signaling and other electrical devices that lie to a special group. For whom it is necessary to use a backup power supply, such as small power stations and batteries.

Before that, this category of reliability in the obov'yazykovo order zdiisnyuє delivery of electricity to the heating points of the apartment houses, as well as elevators. It is important that deyaki community life they are asked for the first category of superstition. Tse can be low and operative care of the doctor, houses with accommodation for over 2000 workers toshcho.

The next category of transmission is also the presence of a number of cables, as they are connected to various transformers. Here, with the cable of either the whole transformer, the electric supply of the living house will be transferred to another period of time, which is necessary for the recovery of a breakdown. A break in the electrically supplied apartments is allowed, but only for an hour, the electrical staff connects the entire booth to the working cable.

Living house in different transformers can be built in two ways. First: rozpodіl navantazhenny booth vіdbuvaєtsya equally between both transformers, in the event of an accident of one - all vantagenzhenya timchasovo switch to the other one. Another way: out of two cables, only one is permanently used, and the other fails the backup function. But it is necessary in any case to connect cables to different transformers. Otherwise, the category will come.

The relevant standards transfer electric supply of living quarters for a different category of housing, which may include electric stoves for more than 8 apartments, as well as houses with gas stoves, hanging behind five tops.

The third category is the simplest. At the same time, the living booth will remove electricity from the transformer substation through one electrical cable. In the event of an accident, such a category of dependability transfers a break at the electric supply scheme of a rich residential house, no more than a lower one for extraction.

The third category of electric supply of bungalow apartment houses is not more than 5 surfaces, some have installed gas stoves, houses of gardening associations and houses, provided with electric stoves, some 9 apartments have less.
