Electrical what is included. What is included in electrical installation work? Electrical work for industrial facilities

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, that’s good, then you will understand what you paid for and how much.

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. Dismantling 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

This is what a fairly complete list of works looks like, 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 consumption of 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.

When performing electrical installation work, you need to take into account that it consists of a whole set of tasks, the solution of which is necessary for the subsequent connection of devices and devices operating from the electrical network.

This stage of construction or repair work is one of the main ones, because it is thanks to electricity that a person can live in his home in complete comfort.

Initial stage of electrical installation work

Before starting work, specialists develop a power supply project aimed at eliminating any inaccuracies or errors at the stage of all work. In the event that a deviation from the project occurs, all further work should be suspended as it could be life-threatening.

In addition to the development of the project, the calculation of the total electrical loads supplied to the network from all connected electrical consumers is carried out.

After that, obsolete or failed sources of the power supply system are dismantled.

Quite often, new elements are installed in existing grooves, which sometimes require preliminary preparation.

If work is carried out in a new building, then all niches are completed in full.

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 “electrical installation work” - this 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:

• approval of design 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 installation 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. A huge amount of waste and garbage makes such work 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.
