What is included in the production of electrical installation work. Stages of electrical installation work

In order to understand the formation of prices for electrical installation work, you need to understand this in detail. This process can be divided into several components.

This article will explain each expense item in detail. An estimate containing all necessary financial expenses is provided to the customer for final approval.

First of all, it is worth noting what we mean by the phrase “electro installation work"is a process that represents the implementation of a whole complex of highly specialized work on the installation and adjustment of household power supply.

In relation to residential premises, electrical installation work means replacing all switching devices (sockets, switches), as well as replacing conductors electrical wiring.

However, it is impossible to immediately move on to the designated area of ​​work. The stages look like this:

• coordination project documentation;
• budgeting;
• coordination of all shift points with the customer;
• transportation;
• installation.

From the above list it is clear that the stages cannot be performed independently of each other. Each of them is a logical continuation of the other.

Experts are accustomed to dividing electrical work into several parts. The first of them is preparatory. In this part, specialists install the necessary fasteners for installing the necessary electrical devices.

As a rule, this is carried out during the construction of the building itself. Great amount waste and garbage makes similar works impossible when the rooms are already finished.

After all, we are talking about laying electrical wiring, for which it is necessary to organize grooves in the ceilings.

At the second stage, transportation of all necessary elements, which will be present in the wiring.

At the final stage, only a complete check of the functioning of the devices is carried out. Relay protection should also be subject to tests.

The video describes in detail the criteria and nuances of drawing up design documentation for electrical installation work:

Electrical installation work is a set of operations necessary to organize uninterrupted power supply to an apartment, house, office or industrial enterprise. To perform such operations, it is necessary to attract qualified craftsmen with specialized education and appropriate permits.

By ordering electrical installation work from the GSK company, you receive a guarantee that everything - from design to commissioning operations - will be carried out in accordance with the requirements of current regulations. Extensive experience in design, selection of electrical equipment and its installation allows us to guarantee the safety and performance of the power system of any facility.

Stages of electrical installation work

To ensure the energy supply of the facility, it is necessary to carry out a number of measures. Moreover, they affect not only the installation of wiring and the connection of electrical equipment as such.

When implementing an energy supply project, it is necessary to:

• Agree on the list of necessary operations by drawing up a diagram of the location of energy supply facilities.
• Approve the power supply project for the facility.
• Compose technological maps taking into account labor protection measures.
• Complete all necessary preparatory work: install supporting structures, prepare surfaces for wiring (drilling walls, installing cable ducts or corrugated pipes), secure bases for electrical equipment and lighting fixtures.

After completion of preparation, installation work is carried out directly, including:

• Installation of switchboards with installation of residual current devices.
• Wiring ( power cables, low-current cables).
• Installation of sockets, switches, lighting fixtures.
• Arrangement of grounding circuits and lightning protection systems.
• Installation of electrical equipment with its connection to the network.

At the final stage, the installation team performs commissioning work, testing the system. The object is handed over to the customer only after successfully passing tests and drawing up an approval certificate.

• methods, technologies and developments.

Also, one of their main goals is to unite the main number of representatives and managers of exhibiting companies who can offer domestic participants their wealth of experience in such areas as electrical installation work, methods and technologies for new developments. In addition, on the project it is easy to find out the contacts of developers and suppliers in the field of construction and installation business, power engineers from large industrial enterprises.

A large-scale and well-thought-out program at all levels ensures inexhaustible interest in the exhibition and, in connection with this, a wide range of visitors and experts from various scientific fields. The importance of a thematic incentive event is difficult to overestimate.

Specifics of electrical work

Electricity is part of the system of vital elements for humans, which is a power source for:

• technical support,
• for lighting;
• for heating water;
• for transferring information and data.

Kinds electrical work:

• gating walls for wiring;
• laying low current and electrical wiring of both open and hidden types;
• laying wires in a corrugated or special cable channel;
• installation of sockets;
• switches for open and hidden wiring;
• installation of internal or open boxes for automatic machines;
• cutting out cells for lamps;
• connection of lighting sources.

Electrical work in an apartment is conventionally divided into two categories:

• repair or replacement of specific parts electrical network with a change in their location;
• complete implementation of new wiring and communications with a change in the general scheme.

Majority qualified specialists carry out all electrical installation and electrical work independently, without involving third parties.

Electrical work for industrial facilities

Electrical installation at industrial facilities and replacement of worn-out wiring within one workshop or an entire enterprise, planned replacement of switches and sockets, installation of panels must take into account all the specifics of a particular production and standards of electrical work.

It is worth noting that the replacement of electrical installation products should be based on whether they are designed for electrical voltage overloads, because if the load exceeds the indicators, the contacts will constantly overheat, and over time they will burn out completely. This may cause a fire in the workplace or workshop.

Carrying out electrical work in production premises with a high concentration of humidity, volatile substances, corrosive gases, must be carried out by an installer using sealed sockets and switches closed type. In the event that electrical installation products are used open type, then they are mounted on special sub-frames with screws with a countersunk head.

All electrical and commissioning work on electrical equipment in production, construction sites and in the energy sector is possible only with the help of specialists from professional licensed companies. To replace communications and outdated pieces of equipment, professional employees of electrical installation organizations use cabling and wiring equipment, automation tools and the best consumables in their work.

The quality of electrical work should:

1. Be infallible. This is possible if each link of the system is operational. In such a situation, the installations begin to work from the first start, and after intervals the defects are not detected.
2. Consider the safety of electrical work.
3. Meet the requirements for comfortable use in the industrial sector.
4. Preparation of project and financial documentation and reporting is also required.
5. Installation of low voltage equipment.
6. Electrical commissioning for connected equipment.
7. Replacement of wiring in low-current and power networks, as well as in trunk lines.
8. Electrical installation of lighting.
9. Installation and installation of grounding of any complexity.

After all activities are completed, the work is checked, the electrical laboratory tests all parts of the system and issues a document with a conclusion. During the installation process, specialists must provide various options for expanding the network if necessary.

Our modern world It’s hard to imagine without electricity. Few of us think about technical issues and live by consuming electricity for good. And therefore, when the wiring fails, major electrical work cannot be done without. Properly carried out repairs will allow you to avoid extension cords, which can cause a short circuit, because they load the network. It is worth noting that the basic rules of electrical work are not only the replacement of automation and wires, but also the correct planning of electrical equipment that will be installed later. Special attention should be given to electrical installations in the kitchen and bathroom. Such work is planned in advance, and at the end it will not be superfluous to replace the shield.

You've probably seen advertisements like "Professional Electrician Will Do All Electrical Work," but they don't list the services they provide or what they can do. To clarify, we will tell you what types of electrical installations there are in everyday life and in production.

Types of hidden and external works

Let's start with the fact that all electrical installation work in construction and renovation in residential premises can be divided into two types - hidden and external.

“Hidden” electrical work in an apartment or cottage includes what is done before finishing the walls:

• Laying cables in the wall.
• Installation of electrical installation products.
• and (although this looks more like work for a plasterer or mason, in practice this is done by electricians).

External ones include:

• along the surface of the walls.
• Installation of overhead electrical installation products.
• Installation of lamps.

This type of wiring is most often used in wooden house or in non-residential buildings.

But this is not all types of work performed indoors. There are a number of electrical installation tasks that are performed indoors during the construction and construction of a residential building:

• Pad overhead line power transmission
• and organization of electricity input.
• Installation street lighting entrance or garden plot.
• Commissioning of backup power supply circuit.
• Installation and wiring.
• Laying low-current and information networks.

When laying new lines, electricians use the following methods and types of markings during electrical installation work:

• Marking with painter's cord.
• By laser level(to the leveler).
• Plumb marking.

Both in everyday life and in production, the rules for performing and types of electrical installation work are prescribed in such regulatory documents as: codes of practice (SP) and building codes and rules (SNiP), state standards(GOST) - for each industry and type of structure they are different. Here are some frequently used documents in everyday life.

• SP 31.110-2003 or its updated version SP 256.1325800.2016 “Electrical installations of residential and public buildings. Rules for design and installation"
• SP 23.05.95 or its updated version SP 52.13330.2011 “Natural and artificial lighting.”
• SP 31-105-2002 “Design and construction of energy-efficient single-apartment residential buildings with wooden frame"(basic document for frame construction).

It is worth noting that all decisions and actions of electricians must comply with such documents as (Rules for the Construction of Electrical Installations), PTEEP (Rules technical operation electrical installations of consumers), PBEEP (Rules Safe Operation...) and others.

Features of work in production

In addition to standard operations similar to “household” electrical installation, such as installing lamps, switches and sockets, electricians perform the following types electrical installation work:

• Laying new power lines (in trays, on partitions, over the air and underground).
• Replacement of failed electrical equipment.
• Installation of new equipment, for example, conveyors, power panels, automation, crane equipment, etc.
• Commissioning work at new production sites.

The main difference is that “private traders” are not allowed to perform electrical installation and commissioning in production, but only trained personnel with the appropriate access and qualification groups and who have undergone safety and occupational training. Persons who have undergone safety training and have a sufficient level of physical fitness and an appropriate state of health are allowed to work at heights.

Contraindications to working at height are problems such as: abnormal blood pressure, poor vision (myopia), problems with the musculoskeletal system (joints, spine), cardiovascular diseases.

Before putting into operation, the installations are checked by an electrical laboratory, and the location of equipment and cables, the length of power lines is recorded in statements, logs and, if necessary, changes are made to the electrical design of the enterprise.

In what cases is SRO approval required?

There is such an organization as SRO ( Self-regulatory organization), by joining this organization you receive SRO approval - this is official permission to perform all types of work.

In this regard, individual entrepreneurs and small construction companies The question arises: do electricians need an SRO permit and in what cases can they do without it? Let's try to answer it in simple words.

SRO approval is not needed if you are not engaged in project activities, but are working on facilities that have already been put into operation. Electrical installation work that does not require SRO includes the installation of sockets, lamps, electrical panels and other tasks that arise when laying wiring or replacing it, as well as during individual housing construction(Individual Housing Construction).

If the facility is just being constructed and electrical installation work is being carried out for the first time, then the workers must have SRO approval.

So we looked at the main types of electrical installation work in everyday life and in production. If you have any questions or additions to the material, write in the comments, we’ll discuss everything!

Materials

When turning to electricians for services, many do not even know what these services even include. Everything is especially murky with the services of private traders, who can give up work halfway and never give guarantees of results. This happens quite often: you call an electrician based on one of the advertisements in the newspaper or on a free resource on the Internet, describe the problem and agree on a time of arrival. Not only does the electrician not arrive on time, but in the process of work it also turns out that you will have to pay another thousand or two more. To prevent this from happening, it is necessary to call specialists from trusted companies that clearly regulate what is included in electrician services.

Transparent estimates

To understand how much and what you pay for, the company draws up design and estimate documentation. The first part is rather intended for masters, and also so that you can more clearly imagine how everything will look in the end. But the estimate is intended specifically for you. There are two types of estimates: good and bad. If the estimate only indicates the total amount, as well as a vague list of work, then this is bad. If every ruble is written down, this is good, then you will understand what and how much you paid.

A clear list of works

When concluding, or rather signing, a contract for the provision of services, make sure that it lists absolutely all the work, for example:

• Replacing wiring

1. Removing the old shield
2. Removing old wiring
3. Dismantling old electrical equipment (sockets, switches)
4. Installation of shield and RCD
5. Installation of new wiring
6. Installation of electrical equipment (sockets, switches)

• Connecting a washing machine

Looks pretty like this full list works, for each of which you must receive quality guarantees for a certain period. In the estimate for each item there will be three to five more sub-items reflecting the expense material resources, For example:

• Connecting a washing machine

1. Copper wire PVA 2.5 – 10 meters = 320 rubles
2. Waterproof socket – 1 pc. = 270 rubles
3. Differential automatic – 1 pc. = 1150 rubles
4. Work – 800 rubles

The figures are approximate. The point is that the entire amount is sorted out. Do you understand what electrician services you pay what the materials cost.

What does an electrician do?

This is a deeper topic. It all depends on tolerances. There are electricians who should not be allowed close to electrical equipment at all, but more about them later. Tolerances are classified into categories, where the maximum is the fifth category. With the second or third category, the master can perform any wiring work inside objects, perform work on networks with a power not exceeding 1000V. In principle, it is important for you that the electrician generally has permission to work, but private traders often do not have these permissions, as well as guarantees that everything will be fine after their departure.

Advisory part

Electrician services is a complex that consists not only of working with wires and equipment, but also with a person. It is important to teach the customer how to properly use a well-designed and equipped electrical network. Counseling has great importance and at the initial stage, when it is necessary to calculate the expected loads, draw up a project in accordance with human needs. It is equally important to follow the recommendations of the master, then electrician services will not be needed for a long time, since the networks will not be overloaded. But do not forget, before calling a specialist, to clarify in what order the services are provided, what is included in the estimates, and whether any guarantees of results are given.
