In industrial power supply, the term is used in the form of a simple abbreviation: ABP. Automatic input of power reserve is possible if there is an additional, backup source of power supply. In fact, such a backup source most often becomes an additional backup line, generator or battery installation. Automatic transition to backup power is carried out using relays or special electronic units.

But for a household network, such things seem redundant: relays, electronic components, a backup line, a generator set ... It's cheaper and easier to sit without electricity, or in the light of a flickering lamp that suffers from unstable or undervoltage. However, it should be remembered that the household network of an apartment or private house in the vast majority of cases is single-phase. And the power line is almost always three-phase ...

Putting an electric panel on the street is not such an absurd idea as it might seem. The reasons for this technical solution are as follows:

Energy sales organizations often insist that the meter for energy consumption and, accordingly, the introductory home electrical panel, be located within the reach of the inspector. This is especially true for large suburban residences, where the owners can relatively easily “hide” in the house an additional input past the counter with known goals. On the other hand, the shield on the street support is clearly visible from all sides and does not cause the inspector any doubt or suspicion.

In the same suburban residence, an opening electric shield can also be very impressive. And the desire to save on space and take out at least a metering device and input ...

All rules related to the safety of operation of domestic electrical equipment are of particular importance in relation to a country house due to its isolation. There is no operating organization, and the state of the electrical economy remains entirely the responsibility of the homeowner.

It turns out that in theory, the homeowner should have knowledge of electrical engineering at the level of the person responsible for the electrical industry, which corresponds to the fifth tolerance group for electrical safety. In practice, this, of course, is rarely achievable. However, everyone can remember and learn some rules. We’ll talk about them.

Changes in the wiring diagram and the composition of the home electrical panel should be made only after consultation with specialists. Additional sockets, stationary power consumers, entire newly attached rooms with their own lighting circuits ...

When it becomes necessary to completely replace the electrical wiring of an apartment, the question arises of which method to lay the wire to choose. Depending on the method of laying the wire, the wiring is classified as open and hidden. Below we consider in more detail both methods of wiring, and also note their main advantages and disadvantages.

Hidden electrical wiring is laid directly in the wall under a layer of plaster or under other finishing materials, for example under sheets of drywall. In addition, concealed wiring can be laid under the floor or directly in the cement screed. Sometimes the wiring is laid in specially provided channels of ceiling plates. Open wiring is most often laid in an open way on a wall or ceiling in special plastic boxes ...

Electricity has firmly entered our lives. While it is, we do not notice it. It seems that this has always been and will be, but if he faces the abyss, and we understand that this is a problem. Especially when a power outage occurs without warning.

The lights go out, the TV and computer turn off, you have to adjust your plans, and in addition to this, eliminate the consequences, starting with the search for candles, flashlights and matches and ending with a leaky refrigerator and spoiled foods.

Nevertheless, it occurs and spoils life. All power outages have two types of causes: technical and economic. Technical reasons.
