Electric wiring diagram in a private house. Dependence on the future load. Creation of wire branches for powerful devices

Until recently, domestic electricity networks experienced relatively small loads. At present, the number of equipment and household appliances has increased several times. Accordingly, the load increased, which the old wiring in most cases simply does not stand. In this connection, the question arises of its replacement and the laying of new cable lines. In this case, great importance is the layout of the electricians in the apartment.

Drawing up a wiring diagram

The electric wiring diagram in the apartment has its own individual characteristics. When designing the scheme, it is necessary to take into account the layout and layout of the premises, as well as the needs of the people living here. As an example, it is recommended to consider a typical average apartment.

It consists of several rooms - an entrance hall, a hall, a bedroom, a toilet, a bathroom and a kitchen. Before drawing up the scheme, it is necessary to determine exactly which devices and equipment will be installed in each of the rooms. When carrying out the calculations, it is necessary to take into account the possible addition in the future of new household appliances and a corresponding increase in electricity consumption.

After determining the number of consumers, you need to calculate their load or total capacity. All necessary data can be found in the technical data sheets of the products. After that, according to the formula I = P / U, the load of the device in amperes is determined. Based on the data obtained, a wiring diagram is prepared.

First determine the number of outlets and the location of their installation. For the kitchen provides three outlets for three groups of consumers. Of these, two common sockets - 16 amps and one - power 25 amperes for an electric stove. In the bathroom you need to plan a waterproof outlet under the water heater and a washing machine. In the hall and bedroom it is recommended to install two sockets, so as not to use extension cords. Each outlet is connected to a separate line, which significantly increases the reliability of the wiring. Lines of illumination.

As a result of the application of this scheme, reliable protection of each line from possible overloads is ensured, since all of them are connected to their own automaton. Intermediate junction boxes are used to connect the wires. As additional protection can be installed protective circuit breakers at the input and on each line wiring.

Calculation of material

After preliminary calculations and drawing up of the scheme, it is necessary to calculate the required quantity of materials. First of all, this concerns wiring, since it provides the normal operation of devices and equipment.

The required cable footage is calculated based on the number of outlets, switches, lighting devices and installation locations. Using a tape measure, the distance from the shield to each point is measured. The obtained data are applied to the scheme for subsequent summation. To the general value, another 15% should be added in case of unforeseen situations.

The stock of cable is needed when placing it in corrugated pipes or cable channels. Due to the heating of the wires, it is not recommended to stack them together in excess of the established norms. In this regard, you may need to parallel the gasket, which will lead to additional bends and turns.

Modern wiring is laid using a three-wire copper cable. The cross-section is selected according to the calculated power using special tables. If the apartment has a standard set of home appliances and equipment, then the sockets are fed to the sockets, with a cross section of 2.5 mm2, and to lighting devices - 1.5 mm2.

After determining the need for wiring, all other materials are calculated: switches, sockets, lamps, junction boxes, corrugated pipes, cable ducts, terminal blocks, fastenings and other necessary products. To connect all the lines you need a switchboard. is carried out with the aid of a stabilizer. You can buy one powerful device for the whole apartment or several low-power devices that are connected only to the home appliances that are sensitive to jumps.

Layout of walls and wiring of electricians around the apartment

Before marking, it is necessary to familiarize yourself with the detailed electrical layout, in which each room and the whole building are marked. In addition, it is necessary to study the installation drawings, where the location of each wiring element is indicated. It also contains information on the water supply system, gas pipeline, heating and other systems. It is necessary to take into account the mutual influence of all networks. This will avoid serious mistakes that in the future can not be corrected.

When marking the walls and ceiling, the signs of the places where the sockets, switches, lamps, junction boxes, shield and other equipment will be placed. All necessary data is taken from the pre-compiled scheme.

Under the installation boxes, the boundaries of the depressions are marked in advance. It is necessary to take into account the possibility of subsequent leveling of the plaster, fixing the tension or suspended structures to the main ceiling. The floor level can increase due to additional coatings with parquet, laminate and other materials. These factors help to reduce the internal space of the room and reduce the accuracy of calculations.

The calculations are affected by the absence in many cases of strict rectangular geometry of the premises. Therefore, it is necessary to use equalizing corrections. All marks on the structural elements are displayed in the execution diagram, which must be stored and applied during subsequent repairs, in order to avoid damage to the paved lines.

Shtroblenie walls

For the device of the latent conducting it is required to execute stroblenie walls and ceilings. This is a rather laborious process, requiring the skills of using a special tool and observing certain rules. During the process, a large amount of dust is released. Therefore, all entrances to other rooms are hung with a damp cloth.

For the device shtrob most often used Bulgarian, in which a diamond-coated disc is installed. The grooves are smooth and beautiful. A significant disadvantage is the release of a large amount of dust, which is not always saved even by a respirator and goggles.

The chisel and hammer are best suited for laying strobes in plaster. In concrete or brick walls it is almost impossible to make a groove. For working with such walls it is recommended to use a perforator.

The best option is a shtroborez, which is used for this purpose. In its essence, this is a modified Bulgarian with two disks, located at a certain distance between each other. Moving on the wall is carried out using a special platform. The casing is provided with a construction vacuum cleaner.

Before starting work on the surfaces with a pencil, lines of future wiring, places of installation of sockets and switches are marked. After that, grooves and grooves are cut in the marked places. After laying the wires and installing the sockets, they are fixed with plaster by building - alabaster.

Connection of sockets and switches

Sockets and switches are the most important elements of the wiring in the apartment. First you need to install a junction box, from which the wires will go to the outlet and switch. After that, the pads are installed, into which the necessary wiring accessories are mounted.

For a normal connection of the wire to the outlet and the switch, leave a reserve of about 10-12 cm. After all connections, the operability of the installed devices should be checked. All work is performed when the power is de-energized electrical network.

Connection of automatic machines and RCDs

Protection single-phase networks, with a voltage of 220 volts, is carried out with the help of single- or double-pole automata. The TN-C connection with two wires is carried out as follows: The phase wire is connected to the first terminal of the input machine, and then through the terminal No. 2 and the counter is distributed to the group machines. Zero wire  Passes through the counter and connects to the zero PEN bus.

In addition to automatic machines, the wiring of an electrician in the apartment provides for the connection of an RCD. It should only be installed after the machine to provide protection along with the meter in the event of an increase in current.

If, however, a circuit with three phase, zero and ground wires is used to enter the apartment, the connection scheme will be different. The phase is connected to the first terminal, and zero to the third terminal of the input bipolar machine. Then the phase from the second output terminal passes through the counter and the RCD, and then is divided into group circuit breakers. Zero also passes through the counter and the RCD, and then connects to the zero bus.

Recently, loads on electrical networks have become very large, which is due to the use of a large number of different appliances and modern household appliances. At the same time, wiring in old houses very often burns out, because it is not designed for such loads and has a certain period of operation. Considering this, an entirely new scheme of wiring in the apartment will be required, capable not only of serving appliances with high power, but also meeting all the demands of modern man.

How to start

The design of this section of the chain should be entrusted to professionals who are directly related to such companies. They will not only make all the necessary documentation, but also help to select the right material by performing its installation. However, it should immediately be noted that their services are usually slightly overstated, but if they issue afterwards an executive scheme with a signature, then these costs are fully justified.

The master must be informed about which maximum power  it is planned to maintain the lines. This is necessary in order for the wiring diagram of the wiring in a one-room apartment or other room to have correct automata, a cable of the required cross-section and, if necessary, other safety shutdown or grounding devices.

Production of the project

A typical scheme for wiring in the apartment 504 series for many masters became the standard. The fact is that this layout, which does not like many people with its simplicity and overlapping of several rooms, allows the grouping of consumers most effectively and economically. Therefore, on this principle, it is best to do the project.

Lighting

This line is not the most simple and economical. If desired, it can be carried on the ceiling, making bends only for switches. Even the layout of the wiring in a two-room apartment or in the presence of a larger number of rooms displays the lighting on a separate machine.

It should immediately be noted that the cable for such operations is used with a cross section of 1.5 for copper. However, if one takes into account the fact that many users have recently used energy-saving lamps, then this is too much. If you plan to use lighting devices that consume 24 volts, then you can install a transformer in the line, from which a separate network will be maintained.

It is best to use a cable with a cross section of 1.5, distributing it to the box and from it making branches to the instruments. At the same time on the project, these chains are displayed in a separate color, trying also to select the wire that will be allocated.

Sockets

Usually a socket is installed on the room according to the formula 1 piece per 6 square meters. However, it is better to focus on personal preferences of users and their needs. In this case, all installation points can be combined into one system, reducing to a single package.

On the plans, such lines are marked in red, indicating the locations of the installations. In this case, some projects combine the sockets, even through the internal partition, as it often assumes the layout of wiring in the apartment "Khrushchev". Photos of a similar arrangement are made in houses of this type or when using walls made of plasterboard.

By creating a separate line for the outlets, you can immediately take care of the grounding. However, it must be remembered that it must be connected to the entire house system.

For these jobs use a cable with a cross section of 2.5 for copper. This is quite enough even for short-term use of powerful electrical appliances in the form of irons, coffee makers, tools or a small air heater.

Separate lines of stationary equipment

Quite often in modern apartments you can find such electrical devices, such as a water heater, air conditioner, electric battery or stove. They all have quite a lot of power and need a separate line. In this case, it is always worthwhile to have in the apartment one outlet, able to work quietly even with a welding machine.

Immediately it is worth saying that each of these devices must be connected separately, without combining them. Also, they are made for individual machines that will be able to control their operation in accordance with the power of a particular product.

If it is planned to install electric heating batteries in the apartment, then their connection system requires a safety factor in power, even the input cable. Some companies that install such equipment do not specifically indicate the cost of such a wiring, since it is quite large and requires a separate approach to the selection of materials. However, if the cross section of the input cable allows you to add more load, then everything is quite simple, and it is enough just to conduct a separate line with the connection via the machine.

1. The old wiring layout in the apartment, examples of which can be found in houses built before the 80's and 90's, involves the use of aluminum cables  and wires. However, this material is used very rarely in modern construction, because copper conductors have long proven their practicality, durability and quality. Therefore, it is best to pay attention to this product.
2. The location of the sockets and switches must not only be safe, but also user friendly. Therefore, it is necessary to determine the location of their installation, as well as the height and quantity individually for each mounting point.
3. Usually only the simplest wiring diagram is created, and all work is done taking into account installation rules and additional drawings or sketches.
4. Some specialists, for simplicity of work, transfer the scheme or its individual elements  directly on the surface of the walls and the ceiling. This makes it possible to represent the location of all assemblies and boxes of installation and choose the most suitable place.
5. When creating similar projects, it is necessary to remember that there can be other wired systems in the room. For example, in a modern house or apartment, a fire alarm and alarm system, a telephone line and the Internet, and satellite or cable television are often installed. Given this, it is necessary to completely eliminate the effect of these conductors on each other.
6. It is best to locate the wiring in ducts or special channels, since they can always be accessed or taped with a new box installed. However, if not planned wall plastering with plasterboard, then the creation of special niches or tracks will only take away excess time and space. In such cases, Stroib will be the most optimal solution.
7. The self-manufacturing of channels for laying the cable is a rather laborious process. Therefore, when it is recommended to use a special tool or nozzle. However, one must remember that this process is associated with the appearance of a large amount of dust, which means it is worthwhile to work in a ventilated room and apply personal protective equipment.

Conclusion

Considering all the complexity of such works, it is necessary to entrust their work to specialists. It should be noted that in some buildings and social facilities only qualified masters with the appropriate education and certificate are allowed to create such projects and schemes. This also applies to the installation of the entire system and its further maintenance.

The modern apartment is equipped with a large number of various household appliances. Microwave ovens, electric water heaters, refrigerators, fireplaces, air conditioners, electric stoves - all these devices create a serious load on the power grid.

And if the house in which your apartment is located was built several decades ago, when the set of home appliances was limited to a TV set, a refrigerator and sometimes a vacuum cleaner, the existing wires can not sustain such a load. To avoid the associated problems, it is necessary to timely replace the electrical wiring of the apartment.

With the implementation of all related activities, you can manage on your own. It is necessary only to study in detail the features of the existing circuits of el. wiring in the apartment, understand the order of the work and do everything in accordance with safety requirements.

There are several wiring diagrams in the apartment. Each of them is created to perform a number of tasks.

Structural

Such a scheme electrical wiring  in the apartment is created first. This diagram shows schematically the relationship between the flap, the entry into the apartment and the electrical appliances planned for installation.

All electrical interconnections should be displayed as completely as possible. To display the links in the structure diagram, arrows are usually used.

On each element of the circuit is indicated its value:, power, and also current strength. All these points should be indicated for the successful compilation of the functional layout of the wiring in the apartment.

Functional

In this figure, the wiring elements are shown and the electrical connections between them are illustrated. For this, special notation is used.

  With the above-mentioned notation you can see on the image. Here is an example of a functional wiring diagram in an apartment with two and grounding.

Fundamental

It is the most complete and detailed scheme. The drawing indicates all the elements of the electrical system (fixtures, switches, etc.), as well as household appliances (floor heating, cookers, air conditioners, etc.).

The diagram shows the lines of laying the wires, the places of installation of the pick-up boxes, connection buses and other elements as precisely as possible.

Estimated

One of the most important schemes for connecting electrical wiring in the apartment. It is created for electric switchboards. The diagram shows the introductory machines that are protective for the individual wiring groups. When compiling, special conventions. Also on the drawing all wires and groups of electricity consumers are displayed.

Each element of the circuit is accompanied by the necessary nominal characteristics.

For example, the number, cross-section and the mark of cores are indicated for the electric cables, and for the automata the value of the operating current is given.

After compilation, the necessary materials are purchased for laying or replacing the electrical wiring. Also, the design scheme allows you to break the apartment wiring into groups.

Mounting

The wiring diagram displays electrical connections  in the serviced apartment. The drawing plan has the form of a detailed table with the following points:

• place of exit and direction of the laying of each cable;
• terminals for connecting cables;
• characteristics of the wires.

Wiring diagrams of the electrical wiring of the apartment are quite rare, because almost any qualified electrician can do based on the calculation scheme. In the rest, they are usually guided by the situation.

Stages of installation and replacement of electric wires

If desired, with the replacement of electrical wiring in the apartment can be handled on their own.

However, it is important to remember that this is a potentially dangerous job, because Electricity may cause irreparable damage if improper and careless handling occurs.

In the rest, follow the guidelines and everything will turn out.

Drawing up an electricity supply plan

First of all, you must draw up a detailed plan of your apartment and point out the places for installing the power outlets, and lighting devices.

For more convenience, break all consumers into the following main groups:

• electric socket;
• lighting;
• a bathroom;
• electric stove (kitchen).

  To each such group is laid their own cable from switchboard. With a similar scheme for installing electrical wiring in an apartment, failure of one of the groups will not affect the performance of other consumers.

It is necessary to make the optimum, according to the current. The thicker the veins used, the more money you spend to equip the wiring. Too economize on this is not worth it, but be sure to remember the following important nuance: in case of laying one thick cable, the branch will need to be performed in.

Moreover, the arrangement of too many connections inevitably leads to a decrease in the reliability of the electrical wiring.

Do not connect all wiring to one group. The bathroom is best connected with a separate line, because such premises require special precautions. This line is recommended to equip.

Dismantling old wiring

Proceed to dismantle the elements of the existing wiring. De-energize the apartment with the help of a shield.

Dismantle the wires from the distribution boxes. The covers of these elements, as a rule, are located under the ceiling. The procedure is as follows:

1. the cover of the distribution box opens;
2. the input lead is cut off and insulated;
3. all wires are deleted.

If the wire can not be removed, it must be cut off and insulated as qualitatively as possible.

Laying of new electric cables

After dismantling the old cables, proceed with the installation of new ones in accordance with the chosen wiring diagram in the apartment and with pre-compiled drawings.

Owners of apartments often prefer hidden wiring. For laying wires according to this scheme, walls must be pre-prepared with shrouds. For this purpose it is convenient to use a perforator, or even better - self-made.

Shtroby laid strictly perpendicular or parallel to the surface of the floor - the diagonal laying of wires is prohibited safety techniques.

The height of the installation of outlets and switches should be selected at your discretion. Do everything so that in the future you feel comfortable. The only important note: should be installed at a distance of at least 300 mm from the floor surface.

Checking the quality of work

After laying and fixing all the wires in the prepared channels, you should make sure there are no short circuits on the mounted line. This check is performed using a tester.

After making sure there is no short circuit, connect the line to the voltage. Next, you need to check the operability of sockets and lighting fixtures with a phase indicator or a tester.

In the end, it remains only to seal the channels with plaster. This completes the work on the replacement of electrical wiring. In order for them to be as successful as possible, one should remember simple safety recommendations and adhere to them in the process of carrying out planned activities.

Before starting work, be sure to disconnect the apartment and additionally check the absence of voltage with the help of a specially designed device.

The handles of all toolboxes must necessarily be isolated. If there is no insulation on them, do it yourself.

In the event that the switchboard is located on a landing or in another place of common access, be sure to hang a warning sign about the work on the line.

Remember: disregard for safety recommendations can lead not only to an early breakdown electrical circuit, but also to much more terrible and irreparable consequences, both for the apartment and for the people living in it.

Follow the instructions, treat electricity with due respect, and everything will necessarily work out.

Successful work!

  - this is the first thing you should pay attention to before you start of electrical installation works. The installation of the wiring will become much easier if the wiring diagram of the house is at hand.

Purpose wiring in a two-story house

The wiring diagram in a private home is primarily necessary in order to make a list of consumables. With its help, you can calculate the length of the wire, the number of outlets and switches, junction boxes, mark the places of marking.

Also, the electricity wiring diagram in the house is needed in order to determine the location of the meters and the switchboard.

Wiring and installation of wiring

To connect electricity to the site where a two-storey house will be built, this is one of the initial stages of the site purchase. A typical scheme of wiring a private house provides for the mandatory signing of a contract with an electricity supply organization. This item is necessary, since the contract specifies the method of electricity supply, the scheme for entering electricity into the house and the allocated capacity.

After the stage of signing such an agreement is passed, we proceed to the next stage - installation. The wiring diagram in the private house divides the wiring harness into the following stages:

1. Rough installation of electrical wiring. At this stage, it is common to dismantle the floor, wash the surfaces, clean dust, remove garbage. At the stage of rough erection a scheme of electric wiring in the house, calculation of the necessary amount of materials, drawing up of estimates, installation and installation is made.
2. After finishing the rough work, they begin to finish the premises and carry out a clean installation. This stage is final and includes: the installation of fittings, lamps, motion sensors, etc.

A typical wiring diagram of a private house provides for the cost of wiring installation.

Highly a good option  equipping a two-storey house with an electrical grid is considered the installation of wiring with insulators. This method is characterized by high strength. When shrinking the house, the wires do not hurt.

Upon completion, this method allows you to quickly determine the location of all electrical points. And most importantly, easy access to the replacement of all switches and sockets in the house.

Wiring diagram in a private house

The wiring diagram in a private house consists of the following parts:

• switch box. It performs the distribution and protective function and is the main element of the electrical wiring. The location of the flap must comply with regulatory documents and an easy and unhindered way of access to it should be provided. The switchboard must not be installed in rooms where water leakage is possible, because electrical circuit  The wiring in the house must be protected.
• Electrical networks that move away from the shield. The wiring diagram of a two-story house provides for such types of networks as cable and wire. Wires in a two-story house can be held both hidden and open.
• Electroadjusting products. To them, the wiring diagram in the private house includes sockets, switches and fasteners. The wiring diagram in a private house is a way to manage the load. Its configuration depends on the number of consumers and their location, on how to manage them and protect each of them.
• Calculation of loads. It is necessary to correctly approach the choice of type and cross-section of the cable and it is better to use the services of a specialist who will conduct a professional calculation.

The wiring diagram in a private house can be of the following types: open wiring, concealed wiring, retro and wiring in a wooden house.

Be sure to observe when conducting electrical wiring in a two-story house. A typical wiring diagram for a private house provides that when wiring is installed one should not leave areas with old wiring, since in the future it can affect the normal functioning of the new one. All wiring connections are installed in special boxes, which will facilitate access to them if replacement is required.

All open parts of the wiring, which may be under voltage, must be earthed. If the wiring is installed in a room with high humidity, it is necessary to use a decoupling transformer, due to which the risk of electric shock is minimized.

Safety in this case is the most important, therefore it is necessary to carefully approach the selection of wires, sockets and other devices.

Depends on the quality of the devices and on the careful attitude to the wiring process depends safety.

All work on installing a new and replacing the old electrical wiring, no matter where they are produced, in an apartment or a private house, in a dacha or in a garage need a competent and thoughtful approach. To begin this complex process is necessary with the drafting of electricity supply, on the basis of a thorough thought over the plan for the arrangement of all the electricity of housing. The project can be made in the old manner on paper with the help of color markers or done on a computer, using the simplest graphic program. In this article we will consider in detail how the drawing of a wiring diagram in an apartment and a private house is being carried out.

Determine the location of furniture and equipment

Before drawing up the scheme, it will be important to take into account the layout of the premises, the planned arrangement of furniture and the placement of stationary electrical appliances. The places of installation of electrical fittings in the room should be chosen so that they are not crowded with sofas or cabinets and provide comfortable access to switching on / off lighting and electricity consumers. It will be better if the discussion on this complex issue is made on the family council.

First of all, it is necessary to make a plan of premises with the indication of window and door openings. In order to make it easier to calculate the required number of cables and wires in the future, it is better to make a plan on a scale in accordance with the dimensions. The process of designing the wiring diagram will be considered in the example one-room apartment. The name of the premises on the plan is better numbered and the decoding is specified separately.

Where: 1 - hallway, 2 - bathroom, 3 - kitchen, 4 - hall.

Optimum installation locations for sockets

After that, it is necessary to put on the scheme places where it is planned to place pieces of furniture and stationary electrical appliances. If the consumer equipment is highlighted in red, this will greatly simplify the work on further drawing up the wiring diagram. All items of electrical engineering are recommended to be numbered and fixed in decoding: 1 - washing machine, 2 - dishwasher, 3 - electric stove, 4 - acoustic center, 5 - TV, 6 - music center, 7 - personal computer.

Drawing up a plan for the location of furniture and equipment will allow you to determine the points of optimal installation of the sockets. Layout of sockets in the apartment:

Lighting scheme

In the classical version, the ceiling fixtures should be located in the center of the room, the location of which is at the intersection of the lines passing through the middle of the length and width of the room. In the hallway, made in the form of the letter G, 2 lamps are installed.

When applied to the layout of the circuit breakers, it must be taken into account that the door can open inward or outward, be of the right or left execution. The open door should not interfere with free access to it. Switches, as a rule, are located inside rooms. Exceptions are rooms with high moisture content, which include laundry, baths, bathrooms. This is done to ensure electrical safety and security of switching equipment.

On the presented plan of electroconducting it is shown, that the switch of illumination of a bathroom is outside of it.

Routes of laying cables and wires

After determining the location of luminaires, switches and sockets, it is necessary to draw up a scheme of electrical wiring routes, this design phase is the main part of the work. The layout and installation of wiring is greatly simplified if suspended ceilings are installed in your home or apartment. In this case, the wires are laid in the corrugated tubes and fixed to the black ceiling. In order to save the wire, the routes of the wiring are selected by the shortest distance. In the stems for plaster lay the wire that connects the distribution boxes with switches and sockets. In the standard version of the arrangement of ceilings, the wiring is laid in pre-punched stitches on the walls of the room. To connect the lighting fixtures, the wire is passed through the channels of the ceiling slabs. Example of a gasket cable line, in accordance with existing standards, is provided on the scheme:

The route plan for the electrical wiring should be started from the furthest point of the electrical network. In this case it will be double socket  in the hall, it must be connected to a junction box, which is expediently installed at the entrance to the room. Then, the route is traced through the wire that connects the second outlet.

The lighting network will consist of wires, the first of which runs from the box to the switch, the second one, connected to the ceiling light, is laid in the channel of the slab. The junction box in the hall is powered by two wires from the distribution board installed in the hallway. It is also necessary to provide, if possible. In this case, the wiring will be three-core.

By this principle it is necessary to draw up a scheme for laying the wiring in the other rooms. For the sake of completeness, we can assume that the kitchen has a suspended ceiling. In this case, the electrical wiring will be laid in the corrugated tubes, fixed with a nail to the concrete slab, the routes of its laying will be chosen taking into account the shortest distance. Descents to the electrofurniture will be made under the plaster.

It should not be forgotten that the electrical supply of the premises is made by at least two groups of wires, one of which provides power network power, the other is for the lighting network. In more detail about that, we told in a separate article.

It is possible to save considerably if the sockets connect honey to themselves by "trail", bypassing the distribution boxes. Experienced electricians do not recommend to practice this method of connection, due to the occurrence of a large current load at the outlets. In addition, when using such a method of connection, the failure of one outlet may cause de-energization of the entire power network.

In conclusion, on the basis of a ready-made and correctly drawn up scheme, the required meter and wiring section, the required number of outlets, switches and junction boxes are calculated. The cross-section of conductors is selected based on the estimated current load of the consumers. About,
