Most often, the idea is to change the wiring in the apartment, occurs when planning overhaul. Moreover, the replacement of wiring refers to the most complex and expensive work. On the peculiarities of the replacement of wiring and towing difficulties on this path will be discussed in the article.

Wiring replacement objectives

Replacing the old wiring in an apartment or house is based on three circumstances:

1. Removing aluminum wires and laying copper. Aluminum wires were widely used for several decades ago due to low cost and environmental safety material. However, in the future it became clear that aluminum was not best Material For wires, since over time, under the influence of loads loses its qualities, becoming fragile. In addition, aluminum wires are destroyed due to electrocorrosion, the soldering of this metal is characterized by complexity, and aluminum twists quickly weaken.
2. Change of electrical power supply (with deaf-earth neutral to protective ground).
3. Refusal to the scheme providing for the branching of wires in favor of creating groups with dedicated branches. The old branching scheme of the wires is an forced decision from early Ranges, when there was a lack of non-ferrous metals, if necessary, to quickly carry out the electrification of the country. In the 1990s of the last century, a new standard of electrical supply was adopted - TN-C-S, which allows to provide greater safety of consumers.

Stages of mounting electrical wiring

The replacement of electrical wiring in the apartment is carried out in several stages:

1. Creating an electrical supply scheme.
2. Development of Wiring Wiring Plan, its coordination.
3. Establishment of repair showcase.
4. Wiring.
5. Installation of elements (automata, switches, protective shutdown devices) and stationary electrical appliances.

The figure above shows a single-line electrical supply scheme where KWA is an electric meter. Kosy dashes, crossbing wires, indicate the range of phase (L) and zero (N) located nearby. The protective wire (PE) is not crossed, since it is laid separately. If we are talking about a three-phase system, then the diagram will be three invasses.

Note! Drawing up the scheme requires qualifications: it is not easy to do this work independently, therefore it is better to entrust the plan to a specialist.

Power consumption planning

When laying electric wires It is necessary to proceed from the power consumption. For cottage settlements, consumption limit is usually from 10 to 20 kW to the house, but for housing in apartment house Such numbers are unreal. With such a power, it is not possible to avoid constant knockouts of the machine or even the failure of the house wiring, since the maximum limit on the residential unit rarely exceeds 2 kW.

Nevertheless, it should be borne in mind that the total power of electrical appliances in the dwelling can significantly exceed real consumption in the moment. This is due to the fact that at the same time all household appliances almost never work.

For apartments in size 50 - 100 square meters You should proceed from the following data:

1. Main machine for 25-32a. Recommended stock coefficient - 1.3 - 1.5.
2. Protective shutdown device - 50A.
3. For the kitchen requires two veins of the wires (cross section - 4 square millimeters per each). For both branches, it is used on a 25-ampered machine and a 30-ampered RCD. The bathroom is powered by wires that are from the kitchen.
4. Air conditioning: Wiring branch with a cross section of 2.5 square millimeters, automatic - 16a, RCD - 20A.
5. Chains of sockets and lighting chains: one for each room (in addition to the bathroom and toilet). Wire section - 2.5 square millimeters. It is not necessary to the UZO, as a general-welded device is used.

Drawing of the circuit

As a base, you can take the wiring scheme shown in the figure above. Its upper part can be left unchanged, but it should be changed in accordance with specific tasks. The device of the protective shutdown device is not fundamental - you can deliver any. Designations can be found in reference books (annex to PUE) and GUTE (in this case we are talking about GOST 2.755-87).

Note! When creating a drawing, the dimensions of the symbols of the elements should be observed, since their scaling is unacceptable.

Preparation plan

The figure above shows the plan of electrical wiring.

Explanations for the plan:

1. In all rooms from the electric meter, at least the pair of wire branches (lighting and sockets) should be sent.
2. Since in the standard apartment one bathroom, in the system of additional equalization of potentials there is no need. This branch of the wires is indicated by a dotted line.
3. In the bathroom you need to specify only the ceiling waterproof lamp and boiler.
4. Wiring branches should be determined to connect points and stationary electrical appliances. Under stationary are understood by the devices, rigidly mounted in carrying structures or feeding through all-in-point connections.
5. Do not overload the scheme of trifles such as LED ceiling lights.
6. The branches of the wires going to the balcony or the loggia are unacceptable - this is against the PUE Rules.

1. We take a plan of residential premises in DEZ or BTI.
2. Scan the obtained plan.
3. In Photoshop, remove the old designations of electrical wiring, stationary devices and connection points. After that, we apply new designations based on the compiled posting scheme.
4. Print the resulting scheme.

Electrical equipment room

To properly compile an electrical power plan, it is necessary to install the number of connection points and the composition of stationary equipment located in the house.

Bathroom

For bathroom characteristic high humidity Air and sprawled floors, which makes it providing special electrical safety measures. Besides sunset in hot water The body resistance to electricity radically decreases: the closure current in this case may exceed 5a, which is deadly. The power of damage to electricity depends on the time of contact and the Uzo in this case will not help.

At the same time, in the bathroom there are powerful consumers of electricity, including washer and water tank. The rules of operation of the electrical installations allow the installation of outlets in the bathroom using a separation transformer or the RCD, however, the following steps are recommended to ensure complete safety:

1. The electrical wires from the water heater and the fan are replaced by a longer. The length of the cords should be enough for them to pass through the hole in the wall and got to the sockets of the neighboring room (most often the kitchen). A cord is not attached to the boiler, and in the case of a fan, the re-equipment of the device threatens only a guarantee loss, which is unnecessarily due to its low cost. Wires must contain three veins and a protective conductor.
2. Buy an extension cord without a cord, but with a grounding of three nests. The extension cord is equipped with a three-core cord.
3. Wires from Electric household appliances Supplies of Eurostright forks. The cords are placed in a polyvinyl chloride case.
4. The plug of the water heater is connected to the socket on an ongoing basis.
5. The extension is fixed in the bathroom on self-drawing.
6. The washing machine is connected through an extension on an ongoing basis. The remaining nests can be used for local illumination, hair dryer and other small household appliances.
7. The fork of the extension in the adjacent room is included as needed.

So, such non-hard actions can be avoided by the presence of the bare ends of the wires in the bathroom, which will significantly increase the safety of residents.

Restroom

Like a bathroom, the toilet requires only a branch of lighting wires to the lighting device. The lamps of the bathroom and the toilet can be connected sequentially to a single branch. Claims from electricals in this case will not be.

Kitchen

Based on the foregoing, the kitchen needs a pair of wires of wires: from the bathroom and their own. Wired section - 4 millimeters. It will take a protective machine. For your own branch of wires in the kitchen, not one, but two triple sockets. Dishwasher, oven, small kitchen appliances, lighting devices can be connected in them.

The extension belongs from the bathroom, connects to a separate outlet. The refrigerator works through an outlet of an additional group, which is installed on the opposite wall. Sockets of the main group and bathroom is recommended to mount for kitchen furniture - Just below the countertops, but as far as possible from the sink.

Hall and corridor

Here you will need a pair of wires of wires: for sockets and for lighting devices. In the extended corridor, at least two lighting points are necessary. The nearest point to the outlet can be made in the form of a sconce and put food from it. The remote point will be a ceiling lamp feeding from the branch.

Children's room

Regulations for children's premises requires the location of the sockets at a height of at least 180 centimeters from the floor. This requirement applies only to specialized children's institutions, therefore, in a private housing, this provision is a recommendatory nature. If desired, the socket can be equipped with a protective disk or other similar device.

Living spaces

For residential rooms The circuit 2N + 1 is used, where N indicates the number of rooms. As an example, consider a two-room apartment:

1. The living room is 1 branch of wires for the main group of sockets, 1 - extra, 1 - on the lighting devices.
2. Bedroom - 1 Main Wiring Branch, Other - Lighting. An additional group is associated with an additional living room group.
3. An additional kitchen group can be connected to an additional bedroom group.

In 2 - 3-room housing can be used 10 - 15 branches of wires, including for air conditioning. The vehicle of the air conditioner ends with a socket, despite its stationarity.

Height of placement sockets

The perfect height for the location of the sockets is 25 - 40 centimeters from the floor. In this case, it is convenient to include, they do not spoil the interior and do not interfere with the installation of furniture.

The outlet for the air conditioner should be placed above, as the equipment is under the ceiling, and the cord should not spoil appearance walls.

Note! Excessive number of outlets reduces wiring reliability.

Tools and materials

To replace the wiring, you need the following toolkit:

• a perforator equipped with a brown of concrete, a crown drill, bits and drill kit;
• bulgarian with a circle around the stone;
• soldering iron;
• indicator with phase pointer;
• multimeter;
• passatia;
• screwdriver;
• lamp;
• level and cord;
• putty knife;
• electric portable lamp.

You will need a certain set of materials:

1. Terminals. This option for replacing wiring in the apartment does not provide for any twists or soldering. Wiring is stable. Conduct connections are carried out in the introductory shield on terminal and final points. Terminambles can be purchased by a session - 5 pairs with 10 contacts. It is necessary to 3 - 5 sections.
2. Outmeal. Boxes must contain protrusions so that they can be fixed by alabaster.
3. Cable. The best way - russian brands VG or PUNP. These cables can be used even in the cheese concrete. Both types of cable are single-core, which allows you to save when they are laying.
4. Channels for wires. Old pipes need to be removed and used metal corrugations instead.
5. Introductory shield. It is selected based on the need to place 4 automata, 4 protective shutdown devices and 4 terminal shots.
6. Insulating tape.
7. Conductive paste.
8. Alabaster.

Posting Replacement Instructions

Work is carried out in several stages.

Creating a house

First you need to provide electricity to the work tool. We install on the cutting board or plastic socket and a 16-ampere machine with a wire cross section of 4 square millimeters. In addition, you will need an extension.

After turning off the electricity in the dwelling. To do this, remove the plugs and turn off the machine. We remove the dose and let out the wires from the electric meter. To the wires through a dense twist connect the time. It is thoroughly insulating the butt sections with a wire and crepim at the wall to the wall. We connect the power in the apartment and start the installation.

Creating a stroke and installation of conversion

Channels must be straight, located horizontally or vertical. Horizontal shoes lay in 50 centimeters from the ceiling.

For convenience, you can use a stand (for example, a stepladder) with a reliable support. At first, for sticking, we use the grinder, and then - chisel (for greater excavation). Niche for picklers are done by the crown (if it comes to concrete - only chisel).

Laying of wires

Cut the suitable slices of corrugations and wires. We put the wire in the corrugation. After that, we install in the niche and fix the alabaster of the opposition. Next, we install the corrugations in the shoes, and the endings of the wires are placed in the opposite. We bring the introductory part of the corrugations to the junction box, we apply a conductive paste. With the help of a tin clamp and screws, create a connection with the terminal box of the grounding of the panel. Turn off electricity and time. We bring the wires to the shield from the electric meter.

Color wires

For neutral, blue or blue color is used, for a protective wire - yellow with a green strip. Phase wires can be white, brown, red or black.

It is allowed to connect wires of only one color. You cannot translate the phase to zero or phase to the phase, the switching switch with a rupture of zero is excluded.

Now it is necessary to apply a layer of plaster near the pickles and blew the wallpaper (or other decorative material).

End of work

After applying plaster and sticking wallpaper, you need to restore access to submersers. For this, conversion cutting along the contour. After removing excess plaster, you can start using sockets, switches, lighting devices, water heater.

When the sockets are installed, go to the assembly of the power scheme with electricity on the inlet terminals. However, the input from the electric meter is still not unconnected.

Note! All branches of wires before the direction to the terminal bar we test the device for a short circuit.

We temporarily connect the power supply and find it with the phase and zero indicator on the wires that run from the electric meter.

Turn off the power supply, we supply the wires of the phase and zero to individual terminals. We again check them on short circuit with running machines.

Conclusion

Replacing electrical wiring in the apartment with your own hands is an extremely difficult task for non-professional. Before proceeding with such work, you should soberly assess your knowledge and practical skills.

If confidence is not enough, it is best to invite specialists, since the unqualified posting replacement can do it much more expensive, and not only in the financial sense.

With the need to replace wiring in a private house, more powerful faces if the home line is obsolete and cannot withstand the load from modern household appliances, like an electric boiler or plates. Next, we consider modern electrical installation solutions, as well as a visual video lesson, showing how to replace the wiring at home with your own hands.

Determine the complexity of work

So, first, you must make an analysis of the old wiring and find out the following points:

1. Is present on the plot. This is very important, because without the presence of a grounding circuit, you can suffer at the failure of household appliances or test isolation.
2. Is it possible in a private house or you need to make a complete replacement of electricians. Perhaps in some rooms recently been repaired and, accordingly, a new, more powerful cable, which will suit modern requirements.
3. Will you be able to carry out the electrical installation or for this you will have to hire a specialist. It should be noted here that it is easy to replace wiring in the house with your own hands, but the event is time consuming and requires special caution. If you do not doubt your abilities, of course, do everything yourself. Otherwise, initially find out the cost of the master's work, because To do this, you will have to give a considerable amount of money.

Having collected all the necessary information about the complexity and front of the work, you can move on to business. About whether it is worth fully changing the old wiring to a new one, describes in detail in the video:

Pros and minuses of complete wiring replacement

Create a wiring scheme

At this stage, you need to think through the cable layout scheme over the air and indoors. It is also necessary to properly design, which will be located on the site of the house. We recommend that you familiarize yourself with the following options:

As for grounding, it is better to give preference to the triangle system:

The grounding in a private house is usually done as follows: three metal pins (or corner) are driven at an equal distance from each other so that they are in the vertices of the triangle, after they are equipped with a metal strip - it turns out a grounding agent to which the wire from the shield can be laid. In detail how to make ground we talked in the article :.

By creating a project, you can move to the calculation of materials and the choice of the most suitable elements to replace wiring in the house with your own hands.

Count and choose materials

The first thing you have to calculate is a cable cross section that will go through the air and inside the residential premises. This stage is very important, because It was because of the diameter of the diameter, the wiring is carried out in a private house (the old line is most likely with aluminum cores of a small cross section). Non-easy, so you will easily cope without the help of the wizard.

Inside the private house from the distribution boxes, the wiring will be divided into several groups of different sections:

• for lighting - 1.5 mm 2;
• for sockets - 2.5 mm 2;
• for powerful electrical appliances (for example, boiler) - 4-6 mm 2;

Important! To connect powerful electrical appliances, we deposit the wire calculated by the load and the current requirements, for example, to connect single-phase electrical stove, according to the joint venture 31.110-2003, it is necessary to lay a cable with a cross section of at least 6 square meters. mm. In any case, pre-calculate the temperature in power.

It should be noted that the wiring of the wire can be carried out as open wayand hidden. Which option to choose when replacing, solve you yourself. However, if the construction of the brick is much more advantages at, therefore the technology will be presented with a tangent of this method. If you decide to replace wiring in wooden houseit is better to use.

As for protective automation - and, they are selected for each group of wires separately. A 10-ampere machine is connected to the light, on the outlet - 16a, on powerful appliances Connect to the automatic switch that corresponds to the current to the instrument consumed. How to translate power due to current and back we described in the article :.

All lines are protected by group UzO, their current can be calculated, but in most cases they use the segless rule - the differential current (it is the current and leakage current) of group RCD:

• bathroom - 10-30 mA;
• for other rooms - 30 mA (according to 7.1.79);
• at the input 100-300 mA (according to Pue 7.1.84).

The rated current of the RCD should be equal to one step more than that of circuit breakers that protect this chain. This means that if the machine is on 16a, then the RCD should be on 16 or 25a. Calculation of the current leakage of the RCD for individual devices and network leaks are carried out according to Pue 7.1.83.

Rosettes and switches are recommended to use high-quality so that they can also withstand current loads (on the case labeled in amperes). For open wiring in the house, you must additionally purchase corrugations or electrical plinths, depending on what you select in your case. After selecting all components, you can count their number and go shopping.

We remove the old line

At this stage, you are already starting directly to replace wiring in a private house with your own hands. To begin with, turn off the power in the home in the housing (the distribution panel in the corridor is usually installed). After that, free the rooms from furniture for trouble-free repair.

Old electrical wiring must be completely replaced, ranging from junction boxes. If for some reason it is impossible to pull the cable from the shoes, it is better to leave it, only thoroughly by relating on both sides. Old shoes can be used for a new electrical installation, if you are satisfied with the former location of switches and sockets. If you want to change the track, put new grooves according to the scheme created. As soon as the whole old line is removed, you can move to the laying of the new one.

Start assembly work

We examined in detail in the relevant article with which we recommend that you familiarize yourself. So that you understand all the laboriousness of the work, we provide you with a brief step-by-step instructions By replacing wiring in the house:

1. Walls are prepared: the pencil and construction level placed the wiring track in accordance with the drawn scheme.
   
2. Bulgarian or strokesis (shown in the photo) creates grooves in the wall, which will serve as a landing place under the entire mains line. By the way, you can, if of course there is a desire.
   
3. Outputs and junction boxes are installed.
   
4. The cable is fixed in the strokes using special clamps either by alabaster (noise the walls are in a hurry, because it is better to do after the replacement of wiring in the house will be fully completed).
   
5. Installed sockets and switches.
   
6. Connects protective automation in the distribution shield.
   

As revealed, the wiring has a limited service period, it is about 20-25 years. Of course, after that it can still function, but the electrical wiring is recommended, since modern devices require a high-quality power source. Replacing the wiring in all types of houses is made approximately by the same scenario.

How to recognize the degree of wiring

Wires come to unsuitability not only from aging, but also from other factors, for example, from powerful electrical appliances that consume a lot of energy, or from unstable maintenance of the power grid. The most voracious apparatus is the heater, it can use energies several times more than any TV.

Contemporary apartment is stuck with various electrical appliances: computer, TV, refrigerator, boiler, microwave, etc. Sometimes they all work simultaneously, which leads to either the power outage by means of protection, or to irreversible processes in the electrical wiring.

Signs that signal the need to replace the wiring:

• Relief of sockets when the device is turned on.
• Resistant smell of pale plastic.
• Liability of wires.
• No power at some points.
• Current leak through the walls.

Having found these reasons, the owner must proceed to the overhaul of electrical wires without slowing.

Wiring replacement is also necessary:

• During the redevelopment of space.
• When carrying out overhaul of the apartment or at home.
• In order to transfer sockets, switches , .

Preparatory work

The first thing that needs to be done is to determine whether the complete electrical wiring is needed or the situation can be corrected by partial replacement. Then the premises are made, where all points of location are indicated. , Lighting devices. It should provide a separate cable for each consumer group: kitchen, bathroom, lighting, sockets. All cables are connected to the distribution panel. If the input automatic replacement is provided, then the correct type should be selected based on the intended load. For apartments, the general purpose machine is suitable. After drawing up the plan, you can go buy materials. It is impossible to save on quality.

Required

• Construction level.
• Screwdriver Set.
• Pliers.
• Sideboards.
• Putty knife.

An important component of electrical wiring is. Professionals enjoy exceptionally copper, which are well conducted, are safe and easy to install. Therefore, the selection of wires is absolutely not complicated.

Before buying wiring, you need to measure the entire path for which the cable will be laid. The consumable material is also required in the form of an insulating tape.

Power consumption

The main thing in the work of the electrical circuit is the absence of failures and overvoltage. Power must be enough for all devices located in the house.

Power has a direct dependence on. To choose it correctly, it is necessary to make some calculations, for this, the power of all devices is summed, 100 W is added to the power of each instrument, and the resulting result is divided by 220. In the case when the resulting number is in the range between 12 and 15, cable cross section 1 , 5 mm2 will be enough. If the number is higher, it is recommended to select a wiring with a large cross section or pave several cable lines from the electrical panel.

Installation of wiring

The rooms are de-energized by disconnecting electricity in the shield. Making sure the absence of current is removed by the old wiring, old wires, sockets, devices are dismantled, the input wires are isolated.

There are two cable laying options. Professionals are paving the wires, moving from the shield to the rooms. After that, switches and sockets are connected, but this option has a number of inconvenience.

If the tenants remain in the dwelling for a period of repair, then a different way to connect the wiring is suitable - from the room to the shield. To do this, the entire replacement of wiring is performed in the same room and is connected temporarily through the terminal blocks in the distribution unit.
Then step by step changes the wiring in all rooms.

Laying new wiring

Mounting methods are three: hidden, outdoor, combined.

Hidden- The most popular and safe. The walls are performed in the wall, in which the cable is stacked. Thus, the electric pipes will be under the plaster and will not spoil the aesthetics of the room.
Outdoor gasket It is carried out on the surface of the ceiling, walls in special channels or under the plinth. It is simple and economical.
Combined The method combines the first two ways - the wiring is partially paved in the strokers, and partly on the surface.
Installation is carried out solely in a horizontal or vertical position, in no case cannot be diagonally. Next, the holes for switches, sockets, distributors are prepared. The height of their location depends solely on the wishes of the owner.

The wire can be laid in old shoes. Channels are covered. Important! Replacing the wiring in a wooden house internal method is almost impossible without attracting qualified specialists, so the installation is made by externally using protective boxes.

Check quality strip

In compulsory, the mounted electroles is checked using a special tester for closures. Only after that the voltage is connected. All sockets are checked, switches. If everything works - you can close the shoes and close the plinth.

Repairs always brings great losses, but if you do some of its stages yourself, you can reduce the costs a little. For example, a tangible benefit will be a replacement of electrical wiring with their own hands - in a private house or apartment (in the panel house, Khrushchev). This operation has its own characteristics. We will tell about everything in the article.

Why and when is the replacement of electrical wiring in the apartment?

There are many reasons for replacing electrical wires, one of them is elementary aging. After all, they, like everyone else building materials, there is a shelf life. It is not necessary to engage yourself with the illusions that the wires of twenty years ago, their shell, as well as other constructive elements There are all in the same exceeding condition, as before.

In addition, it is necessary to take into account the sharp increase in the number of electrical appliances in the house, and some of them can be quite powerful, so the old wiring simply cannot cope with such a load. Someone can "decide" this problem, replacing the machine guns, however, remember that if the value of their rated current will exceed the maximum allowable, then when overloading is possible even fire, and this represents direct danger to life. Well, the last reason why you can replace the wiring, it is its damage during repair work.

Of course, before the critical state, it is better not to bring, but consider what signs indicate that it is no longer possible to pull with replacement. So, as mentioned above, the number of electrical appliances in our city has increased significantly, and some of them are characterized by a high capacity - which is just a heater or an electric kettle. If the load is very big, it can lead to the shutdown of automata. This should encourage you to replace. Of course, you can adjust it, for example, try not to include several devices at the same time, but it is quite uncomfortable.

More serious prerequisites - sparkling sockets and nasty smell molten plastic or rubber. It also testifies to an overly high load that should be immediately reduced, otherwise fire and a large fire is possible. If the wires that are suitable for sockets, machine guns and switches are distinguished by increased lubrability, then this is also a very disturbing sign. Well, the leadership belongs to leakage from the power grid, in this case the floor and the walls will be fed to the current. All this should push you to immediately replace the wiring.

How to choose materials?

But before proceeding close to the question, how to change the wiring in the apartment should be dealt with how to correctly calculate and choose materials. After all, it determines how long the new network will serve as long as well. First of all, you should calculate the cross section of the wires. First, we summarize the power of all electrical appliances in the house, do not forget to take into account the lighting. Then, it is added to this value another 5% and divide the result by 220 and, as a rule, we obtain a number of about 15 A. In this case, the copper wire with a cross section of 1.5 mm 2 will be enough. For current 19 a better suitable Section 2 square, and for 21 A - 2.5, etc.

Making a choice between aluminum and copper cables It is necessary to give preference to the latter, since their shelf life is significantly higher. In addition, aluminum has a lower electrical conductivity, it is inclined to oxidation and crumble in the locations of the beggars. Do not forget to pay attention to the attention and quality of products, otherwise their indicators will not correspond to the stated that will play serious joke. So, it doesn't matter what exactly you pushed to replace the power grid - the unsatisfactory state of old wires, repair, a large load or any other reasons - it is necessary to understand the intricacies of the process.

How to change the wiring in the apartment without the help of an electrician?

It should be borne in mind that the local replacement will not lead to anything good, but will only aggravate the situation. So get ready to spend work in the whole house right away.

How to change the wiring in the apartment with your own hands - a step-by-step scheme

Step 1: Deafling

Despite the fact that this stage is one of the simplest, it can be considered the most important thing - because the slightest flaw and you can get a defeat electric shock. So the main condition is a completely de-energized object - for this you need to successively turn off all automata. Just in case, check the tester or control lamp if the voltage in the outlets is missing.

Step 2: Dismantling

After checking, you can proceed directly to dismantling all wires and points of connection. We first remove all sockets and their boxes, especially if the latter are made of plastic. In principle, if you have a case with concrete WallsWhat is often characteristic of Khrushchev, then in this case, to delete all the wires there is no need (of course, if you do not want to invest new in the old furrows), it is enough just to bite them and isolate the ends.

The lighting cable is often able to carefully pull out, while without picking walls and ceilings, for this you should find their ends in the distribution box and pull them.

Step 3: Compile a plan

Make a detailed layout of the new network and make all the sizes in it, for example, on which height from the ceiling or gender, walls and door logs will be laid wires. This will help you in the future, because everything is very quickly forgotten, and therefore, even a simple nail, driven into the wall, hurts the cables stamped in it, which will turn out not only to the problems associated with the replacement of the damaged element, but can also harm the health. Of course, the location plan can remain both the same, but then deposit all the sizes.

Step 4: Surface Preparation

Old grooves are perfectly cleaning from dirt and dust. If you need to make new grooves, and it often happens, you draw on the wall in the right place two parallel lines at a distance of 2 centimeters from each other, which will be their edges. Then we pass on them with a grinder (the depth of the reise is somewhere 4 cm) and let the middle of the hammer and chisel. Places for outlets, junction boxes and switches are cut with a perforator with a special nozzle. If dismantling the former sockets and switches, you too raged the wall, then you need to raise the space too much.

Step 5: Directly Installation

First install all the boxes, fixing them in the planting places with a solution or alabaster. Next we breed the wires from the shield to the distribution boxes, and then from the last to each specific point of connection. They fit into advance prepared grooves and are attached there in the same way. If the old wires from the lighting devices can easily drag, as described in the second step, then by attaching a new cable to one of their ends, it is possible to replace it without sticking.

Step 6: Check and Plaster

In principle, we have already disassembled how to replace, it remains only a little - the stroke plaster. But first should be tested the received network. It is done quite easily - using an indicator screwdriver or a special tester. When you were convinced of the health of your work, stirred up it in the walls, on this work is completed.
