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 ...

In the houses of the old building on each floor of the entrance, the builders installed an electric input shield. From it they spread an electric network in all rooms. Now another technical decision has been made. All commutations of the electric circuit are carried out inside the apartment where the distribution electric switchboard is mounted.

However, during settlement, it is often necessary to replace or transfer the distribution electrical panel. Cheap designs are simply not capable of fulfilling modern tasks of safe power supply. Even for a modern two-room apartment with 60 m2 of area, more than a dozen electrical circuits are required. Changing the shield model will require lengthening the power cable, and it may be walled up in a concrete wall or not fit in length. It is not always convenient to take a new cable and lay it with an additional routeth, especially when it is fixed ...

When repairing electrical wiring, it is always necessary to have access to the ends of the connecting cables and the contacts of sockets, switches. In modern buildings, a hidden method of installing communications is often used, when all wires are hidden inside the walls for security and design purposes.

To the veins of the cable ends can be reached only at the entrance of the lamp, switch, socket and electrical distribution box. For the convenience of servicing such electrical equipment, certain rules must be taken into account: cables are laid along certain routes provided by the project, in the places where sockets and switches are installed inside the wall, recesses are made to accommodate the corresponding equipment, installation boxes are mounted inside the recesses into which the switches and sockets are mounted. The most favorable time for such work ...

The massive construction of the housing stock and the ongoing reconstruction of old buildings push apartment owners to the need to independently understand the technologies for performing electrical work in their premises. This allows you to create an individual electrical system that meets the specific needs of the owner, rather than using a typical circuit designed for the average consumer.

In order to properly assemble the electrical panel in a newly built apartment, it is necessary to draw up a project, in which it is necessary to provide for the detailed implementation of your needs inside each room, to consider the location of the lights and switches for them, the number of sockets for portable and stationary electrical appliances.Along with electric wires, it is often necessary to lay pipelines for water supply, heating, telephone linesantenna cables ...

Instead of the introduction: in the grammar dictionaries of the Russian language there are no definitions of the words “stroba” or “strobe”. The online service “” does not know them either.

But the Wikipedia joint folk art encyclopedia combines these two terms into one name and sends it to the technical literature: PUE, GOST 21.201-2011.

In these documents, the term "furrow" is used, which is created in the walls to hide electrical wiring or pipelines. This technique not only improves the design of the premises, but also creates additional mechanical protection for the laid communications from damage. However, in colloquial speech among electricians, the word "strobe" is more familiar. A professional tool for cutting them is called a chisel cutter even by manufacturers. Therefore, in the article we will adhere to the prevailing folk traditions ...

In residential buildings there are multi-key switch designs that are complemented by an electrical outlet. They are usually installed in the corridor on the partition at the entrance of the doors, for example: a bathroom, a bathroom, a kitchen.

They can be made in the form of vertical or horizontal structures for placement inside installation boxes built into the wall or with a housing for external use.

Such blocks are available for operation in electrical wiring equipped with the following systems: TN-S, TN-C. Sockets for connecting to the electrical circuit of an apartment equipped with the TN-S system have additional contacts for connecting working electrical appliances with a protective zero through a PE conductor, and for structures using the TN-C circuit, the grounding of the housing of household appliances is not used ...

Despite the fact that the regulatory requirements for the rules for operating electrical installations in residential buildings have changed a long time in the countryside, there are still many houses that are powered by the old TN-C circuit through an electric panel with an induction meter of accuracy class 2.5%, protected by fuses with fusible inserts. Such a scheme has long required modernization.

Even the reconstruction of overhead lines by the power supply organization and the replacement of obsolete open wires with self-supporting insulated models does not always push owners to change the electrical circuit.

Old electrical panels are now operating at the limit of their capabilities and do not fully provide electrical safety for residents and equipment. In order to modernize the electrical panel in a private house, it is necessary to take into account a number of factors ...

The current rules for the installation of electrical installations have increased requirements for the reliability of the connection of protective neutral wires and the electrical contacts created by them. In this case, the connection of electrical appliances should be done through a branch, and not a cable.

To understand the difference between these methods, imagine a fruit tree with a grafted branch. Branches that have grown naturally and extend from the trunk can be considered as one with the tree. The term branching is suitable for them, and the scion is created artificially - this is a train. Under a loop in the energy sector, it is customary to consider a piece of wire connected to an electrical wiring to create a specific electrical circuit.

In other words, the PUE requirement can be explained as follows: the zero conductor protector must be intact throughout its entire length, which means a ban not only on its creation ...
