Owners of cottages and summer cottages on their territory are building garages, baths, small workshops, cellars and other utility rooms, which are supplied with electricity for lighting, heating and other uses. The article gives recommendations on how to reliably and safely perform such work, avoiding the typical mistakes made by home masters.

Before undertaking electrical work, they must be carefully thought out and a plan drawn up on paper. This will save time on the implementation of ideas, materials and money. Official sources recommend using a radial wiring diagram in new rooms to the main distribution panel of the building when cable lines radiate to all consumers from it. This option allows you to have everything in one place. circuit breakers...

Now many people, starting the construction of housing, immediately face the issue of its power supply. Even the very first action - the construction of the foundation requires the use of a concrete mixer, which does not work without electricity. Therefore, you have to look for options for creating a temporary power point and choose the most suitable method.

In order for the work progress not to be disrupted, and all the tools to work well, it is necessary to have electrical energy that is different: in quality, ensuring the rated frequency and voltage parameters for good operability of building mechanisms, reliability and stability, eliminating power failure during work, and safety of use, creating maximum protection of people from electric injuries. In this case, it will be necessary to resolve legislative issues related to connecting to existing energy pipelines ...

In a private house, pumping equipment is used to ensure the operability of the heating system, water supply system. In the heating system, a circulation pump ensures the circulation of the coolant from the boiler through pipelines and radiators connected to them throughout the house.

In the absence of a centralized water supply, water is supplied to the house by pumping it out with a submersible or surface pump from a well or a well. That is, we can conclude that pumping equipment is an integral element of these communications of a private house.

Pumping equipment receives power from the electrical network, so in the event of a power outage the house will be left without the necessary communications for life: the coolant will not circulate through the heating system, and there will be no water in the tap ...

Voltage level is one of the criteria for the quality of power supply. Each household appliance is designed for continuous normal operation provided that it is supplied with voltage that is within acceptable limits. In this article, we will consider the question of what voltage in the household network is optimal for the operation of electrical appliances.

First of all, it should be noted that many different factors affect the voltage level in the electric network. Electricity from the source - power plants to the final consumer, in particular to residential buildings, comes through several stages of conversion. At the first stage, the voltage rises to transmit it over long distances, through the power system.As you approach the end user, electricity goes through several stages of voltage conversion to the values ​​used in everyday life. Fixed voltage values ​​in various parts of the power system ...

We have known the lighting of apartments with the help of chandeliers from childhood. Such lamps are quite easy to connect and work for a long time even with certain installation errors. However, if individual violations of installation technology do not affect operability, they can lead to electrical injury to the owner when in contact with metal parts of the case or when replacing a burnt out foot.

To avoid the typical mistakes made by home craftsmen, read the contents of the article and compare its recommendations with the circuit for switching on your fixtures. Always assemble the wiring so that the phase comes to the remote contact of the cartridge, and zero to the near contact. This technique will save you from electric shock to someone who will replace the light bulb in the chandelier when the voltage is applied to it and accidentally touch the nearest live part ...

In the work of any electrical circuit, attention is always paid to its stability and installation quality. Lighting systems, especially those located above the head, must be securely fixed in the power elements of the building and held in them under the influence of loads of various kinds. The most common methods of installing fixtures on the ceiling can be conditionally divided by use: at industrial, industrial facilities, in residential premises.

In laboratories, workshops, workshops, light should evenly illuminate the entire workspace. For this, large-sized fluorescent lamps are often used, which are distributed in rows at a certain height. The method of attachment may be different. Single devices are more convenient to fix directly to the ceiling surface. However, the great height and the need to place a large number of such light sources ...

A home foreman, planning to repair an electrician in his apartment or complete its laying in a house under construction, must first think carefully about the technology of the upcoming work and the sequence of its stages, including marking the wiring. Otherwise, as practice shows, serious errors arise that require the investment of additional funds and time.

If we turn to the clarification of the verb "mark" the explanatory dictionary of the Russian language, then he explains it as a measurement, marking, designation of the size of something.

With regard to electrical wiring, as well as any technical systems, this means that for marking it is necessary to have: an object - a house or apartment building, in which it will be necessary to lay electrical wires, the owner’s plan embodied in the work project. In other words, the markup process means transferring ...

Electrical installations are closely related to safety issues. With a sharp increase in modern loads, they began to receive increased attention. For this, various protective devices and ground connection schemes are used. Thanks to connecting a PE-conductor to the living room, it is possible to: reduce the devastating consequences of emergencies, prevent fires from faulty electrical equipment, save people from electrical injuries and death. Protective grounding helps solve all these issues.

High voltage electrical energy is transmitted over long distances using transformers.Any household electrical appliance performs an action when current flows through it. The path for it is formed by a closed ring from the generator to the consumer through the wires of the “phase” and “zero”. The potential difference between them determines the value ...
