2001 year. A familiar master entrepreneur brought a vertical loading washing machine from Germany, which had worked out factory guarantees in a German family, and offered to buy it for neighbors with a significant discount and bonuses: a free installation and its 3-year warranty.

We made an agreement and paid the money. The purchase was placed in the kitchen. For seven months the machine worked amazingly, and then, at the most unexpected moment, it flowed while washing the laundry.

It is good that the hostess was at home and from the remote room I heard the sound of pouring water that filled the floor in the kitchen. In addition, the car "shocked" the hostess when she approached her. Naturally, they flooded the neighbors from below. The called master fixed the malfunction and paid for the repair of two apartments without further questions, and the car still works after this incident. The cause of the leak is simple: during a preventive replacement ...

Another selection of the best home electrical wiring articles from bgv.electricianexp.com. The selection included articles that examined various electrical wiring diagrams for electrical wiring in an apartment and a house, wiring diagrams for switches and sockets, and lighting network organization. All information in these articles is for informational and educational purposes only..

Despite the popularity of the topic "electrician in an apartment and a home with your own hands," you can independently engage in the installation of home electrical wiring if you have an electrical education, have real professional skills in this area and clearly understand the danger to yourself and others of poorly done work.

Otherwise, the best option would be a decision to entrust this work to professionals. And the information from the articles will serve as an example for you how everything should be arranged correctly ...

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 ...

Most often in settlements where private houses predominate, overhead power lines are used. However, cable underground lines can also be used.

Part of such a line from the nearest support to the entrance to the house is usually called a branch. It can be laid through the air or underground. Legislatively determined that the branch is owned by the owner of the power line. Maintenance, operation and reconstruction of the branches are his responsibility. Independent work without the consent of the owner of the power transmission line is prohibited.

To create a new branch and connect it to the input of the building, you must have a project that must be agreed with the representatives of the line owner before starting work. The document should reflect a list of all technical solutions and materials ...

Inside modern multi-story buildings and private houses, electrical wiring can work according to different connection schemes to the ground loop. Any owner of a dwelling should know its features in his building, since each scheme in different ways ensures the safety of using household electrical appliances.

All residential buildings are connected to power transformer substations by overhead or cable power lines. Almost all of them have four wires, which can be indicated by the indices "A", "B", "C" and "0" or "L1", "L2", "L3" and "PEN". These wires are planted on the terminals of the main switchboard of the building and routed along it.

Moreover, the PEN conductor can be connected with splitting into two components of the circuit PE and N or directly without any separation. In the first case, the house uses a new system ...

The issues of safe use of electricity continue to become increasingly relevant for the entire population. The requirements of an international electrical company, implemented by regulatory documents in our country, have tightened the rules for the operation of electrical equipment. After that, state standards in force since Soviet times with simplified rules for grounding electrical circuits for residential buildings were revised.

However, a large mass of buildings continues to be operated according to the old TN-C scheme. To re-equip it with the TN-C-S system requires enormous material costs, it is not easy to accomplish all this nationwide. Therefore, such work is carried out gradually, but systematically. The article "Classification of grounding systems of electrical installations" defines electrical circuits for power supply of residential buildings and industrial facilities ...

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 ...

In practice, there are many ways to connect electrical outlets with wiring. During their implementation, different goals can be pursued, from austerity of materials and means to reliable, long-term and safe operation of the equipment.

Given the increasing needs of the population for the use of powerful electrical appliances in everyday life, we should dwell on the most favorable electrical circuit for a home network that provides maximum safety during operation. It should be divided into two components of the system: the power unit, which provides electricity to household appliances through outlets, the lighting system, separated from the operation of the power unit. To create the power circuits of the internal apartment panel, circuit breakers are mounted according to the number of necessary connections. A cable is laid from each machine ...
