How much does it cost to make an electrician? Review + Video How much does an electrician cost in an apartment - conducting wiring, cost of materials and work

Electricity is an essential energy resource for apartments, houses and offices. It is difficult to imagine a building site without an electrician. The standard home network is set up by default by an electrician during construction. But in special situations, you have to do electrification yourself.

Is it possible to perform work without experience and how to correctly do the wiring with your own hands.

How to wire in an apartment

Example

For example, there is a newly built private house or a new apartment with initial finishing, where engineering equipment is needed - electrical wiring and paraphernalia that are included in the kit. It is best to trust professionals to dissolve the electrical network inside the dwelling, but in this case, many people begin to clutch at their hearts when they find out how much an electrician costs in an apartment (taking into account the payment for the foreman's work). In addition, there are regions where professional electricians are in short supply.

Installation of electrical networks in an apartment with the help of electricians is not cheap, but this approach saves you from many problems. There is a definite way out, if you have little money - to electrify your own apartment or house on your own.

But how to do electrical wiring with your own hands if you have no experience? Read the article and inspect all the schemes - this will help you do it yourself.

Schemes and installation options

Serious construction begins with a plan, and the supply of electricity to housing initially involves the creation of a schematic solution. Apartments in a city are usually built in a typical way, which means that a typical project must have a typical electrical supply diagram. We present an example of a wiring diagram for an apartment. This is a common design option for most buildings.

This has certain advantages for the owner of the living space who wants to conduct electricity on their own.

All you need to learn from you is the layout of the channels, and then you can start laying the wires.

It is more difficult to resolve the issue if there are no system channels in the structure of the house. in such a project, additional work will be required:

  • Punch channels in the wall - prepare grooves.
  • Install the protective box.

  • Install the mounting hardware.
  • Prepare landing points for sockets, lamps, switches, etc.

True, it is possible to make open wiring, and although this option is technologically outdated, but due to its "retro" design, it is now popular, especially in country houses. So, we will consider an example of a closed circuit (inside the walls) of mounting a box for wires for electricity and do the wiring with our own hands.

Following the rules and requirements of PES

Electricity does not forgive mistakes, and such a truth must be attributed to the master.

The requirements and rules for electrical installation affect many details of the work, from the correct selection of the conductor cross-section to the device of structures for grounding. The photo example shows conductors based on aluminum, which is insulated with polymer materials.

This option is economical for apartment wiring, but does not guarantee safety and reliability. You should not save on this and if possible, it is better to conduct a copper wire. Copper for apartment wiring must be soft and stranded.

Depending on the expected load, it is required to calculate the cross-section of the conductors (note that this is not a diameter!). How much does it cost to conduct an electrician?

First, we calculate the total load in kW for the apartment version, and for this we need to add up the power of all electrical appliances that will be used in everyday life, taking into account the coefficient:

P = (P 1 + P 2 ....

P n ) * 0. 8

Where P 1 …. P n represent the power of each of the electrical consumers of the apartment (devices), and 0. 8 is a correction factor, since it is generally accepted that a maximum of only 80% of equipment can work in an apartment at a time. Further, knowing the power, it will be easy to choose the required section.

Since the power for electrical appliances for household use is relatively small, the diameter of the wires, excluding insulation for mounting the lead from the panel, will not be more than 2.5 mm for aluminum and from 2 to 2.5 mm for copper.

An exception will be apartments that are equipped with electric stoves and other powerful equipment. In this case, it is required to more accurately calculate the section for the load with a small margin.

The table will show the difference in the cross-section of the conductors, and keep in mind that the smaller the cross-section, the thinner the conductor will be, and it will be much easier for you to stretch it in the channel.

Process details

How to pull the wire in the channel

Each section for electrical wiring contains traction threads - a metal wire with up to 1 mm in diameter. The ends of the thread are usually brought out along the exit and entry holes of the channel. It is enough to tie the leash with the traction thread at the entrance and pull the conductor from the opposite end of the channel using a brace. If there is none, then it is easy to skip it yourself, taking into account the small diameter and sufficiently high elasticity of the steel wire.

Order of work

Installation work for wiring accessories and connection of terminal nodes is recommended to start from a point that is farthest from the central box. Usually, it is an electrical outlet in the farthest room.Work on the installation of residential electrical points usually starts from sockets, and with modern installation requirements for such products, a three-wire configuration is required.

Connecting sockets

Socket terminals are connected to conductors from the power line (phase-zero), and each of the sockets, according to the rules, must be connected to ground terminal to ground conductor.

Conductors (grounding, neutral and phase) usually differ in the color of the marking:

  • F base to original.

  • Zero blue.
  • Earth yellow-green.

In addition, according to all the rules, the grounding conductor has an increased diameter in relation to the other two conductors. When the connection and installation are completed, you should check the integrity of the lines of the current section of the apartment electrical wiring using testing. The process of checking the connected terminal points is carried out using a measuring tester (multimeter).

The check is extremely simple - through the function of measuring the resistance to "close" the circuit. Now you know what kind of wiring to do in the apartment.

For testing, you will need:

  1. At the second end of the channel in the junction box, connect the neutral and phase wires together.
  2. Plug in the test leads of the measuring device, which is included in the measurement of resistance.
  3. Verify that the tester shows a "short circuit".

The same check should be performed for the grounding line, and for this, it should be connected to any of the line-type conductors. In this case, one probe of the device must be moved to the ground bus. It so happens that moving closer to the point of the main entrance, all socket-type terminals entering the apartment will be sequentially disconnected. In this case, after testing each of the sections, it is required to connect the wires inside the junction box. After finishing work with sockets, you can go to switches - devices of communication action.

Installation of light switches

How much does it cost to make an electrician? Review + Video This type of installation work in in general, it is not very different from working with sockets in an apartment. However, there are also technical issues when installing a light switch. So, if the sockets are provided for being connected to the circuit in parallel, then the circuit breaker will form an open circuit through a single-phase wire, which means that the connection will be sequential.

An example of a switching-type block device is shown in the photo, and it consists of two single switches. Usually, such an arrangement of devices is a characteristic feature of an apartment's sanitary unit.

Switches can also be installed in niches of wall panels, but it should be borne in mind that each switching device will work with a specific lighting fixture. From here it is worth choosing the version of the switch - one or two keys.It is also better to test the operation of the wiring switches in the apartment in advance, and this is not difficult to do.

Conductors that are intended for lighting devices should be connected to the tester in the resistance level measurement mode, and then the key can be manipulated. When closed, the tester will show "short circuit", when open, there is no contact.

The luminaire and switch part of the circuit assumes the presence of junction boxes in which, after testing individual sections, the connection will be made to the rest of the electrical wiring.

Meter installation

The main part of the installation options provides for the installation of an electric energy meter inside the apartment. such a control device is installed very close to the entry point of the conductors that emanate from the shield. This requires the installation of not only a meter, but even the installation of protective automatics, which is calculated according to the load - in theory, they switch each functional section of the apartment electrical wiring, as shown in the example.

The effectively protected residential electrical wiring diagram indicates that all excellent properties are available through the installation of circuit breakers and on each separately allocated segment.

Such a scheme will ensure the reliable functioning of the electrical wiring in the apartment, and also makes it possible to eliminate malfunctions without removing the entire home network from voltage. In addition, it will be convenient to test the apartment electrical wiring the first time you turn it on, including each segment separately.

Cost of work (when calling the master)

The approximate cost of replacing electrical wiring in a house or apartment (before installing sockets, lighting fixtures and switches) specified without regard to materials. The price will be higher when it comes to apartments with concrete walls and according to the design project.

A preliminary price for replacement is drawn up after inspection, but for now approximate data:

  • How much does it cost to make an electrician? Review + Video 1-room apartment (up to 40 m 2 ) from about 15,000 to 27,000 rubles (brick or gas block), from 16,000 to 30,000 rubles (cinder block, concrete).

  • 2-room apartment (up to 60 m 2 ) approximately from 21,000 to 28,000 rubles (brick or gas block), from 23,500 to 34,000 rubles (cinder block, concrete).
  • 3-room apartment (up to 100 m 2 ) from about 25,000 to 37,000 rubles (brick or gas block), from 27,000 to 39,000 rubles (cinder block, concrete).

Also, the cost will depend on the type of cable laying, because there are several different options - for ceilings without corrugation and with it (for a "herringbone" mount), wall slitting or only vertical drops, without slitting ( if the walls are "bare brick"). Since each apartment and project is unique for it, the final price for electrical installation may vary.By the way, if we are talking about replacing the wiring in a residential apartment, then 20% of the total amount can be safely added to the cost, because there is no way to open all the windows so that there is no dust; the presence of children, animals and things in the house that interfere with work.

Do-it-yourself electrical wiring in a city apartment is a perfectly acceptable option, but there are some "buts" to solving the issue with this method:

  • First, it is better not to tackle this is the case if there is no experience in electrical installation.
  • Secondly, when thinking over the execution of work, you yourself need to take care of your safety and only secondarily about the benefits.
