By acquiring property in the secondary market, we are always at risk. Two famous market fools from the saying - the seller and the buyer - are constantly trying to get the most out of the deal. Of course, the benefit is possible only at the expense of a vis-à-vis: the seller suddenly forgets about some of the shortcomings of the goods, and the buyer diligently knocks down the price, hoping to get a worthwhile item for nothing.

And the more expensive the acquired property, the sharper the hidden conflict of interests between the seller and the buyer, the more irresistible the desire to deceive the neighbor becomes and the higher the price of the error. Therefore, the situation becomes extremely extreme if the subject of bargaining is real estate. For example, if an apartment is for sale, then the buyer does not have the opportunity to find out all its flaws for certain. Let's say it's summer in the yard, and in the winter it turns out ...

A theoretical and practical guide for those who decide to install a voltage regulator in their home.

A simple layman entering a query on voltage regulators in a search engine will immediately stumble upon the eulogies and abusive speeches of all brands, a bunch of producer countries.

This massive confusion is understandable - high competition does not tolerate sitting out of pants with calls waiting, you need to spin as actively as possible, but the impression is of mass uniformity of all stabilizers, where the buyer is essentially presented only with a choice in price and appearance of the device. And this is not at all true. The main thing in the voltage regulator is its functional filling, its operating range, quality and type of execution. This work is devoted precisely to a detailed separation of the types of voltage stabilizers for the correct choice of the rating and type of stabilizer ...

Work related to the connection of the internal network goes far beyond the elementary electrical connection of the upper terminals of the input automatic machine and the main transmission line network.

The technical nuances and difficulties in this matter are due to the fact that the branches from the power transmission lines and the input itself actually remain without protection against overcurrents of short circuits. Indeed, on a support in the place of branch execution, in the general case, all sorts of protection devices are absent.

Therefore, a short circuit in the branch is fraught with an elementary fire, because the hot arc between the conductors in the case of this short circuit itself will stretch to the very destruction of these unfortunate conductors. For equipment in the substation, there will be no emergency operation: the wrong current level. Accordingly, a protective shutdown will not occur. This situation is most dangerous for obvious reasons for wooden houses. And the most dangerous part of the short circuit branch is wall penetration ...

To date, no overhaul can do without a wiring device and electrical equipment. Even if you plan to carry out cosmetic repairs, and at the same time live in an old-style house, then you just need to replace the electrical wiring. This is due to the fact that in the old rooms the installation of electrical equipment and wires was carried out, designed for loads that are considered to be insignificant by modern standards.

In the sixties of the last century, no one could even think that they would need an electric cable that would withstand the load from many simultaneously connected various electrical appliances.A huge TV, a powerful computer, a refrigerator, air conditioning, an electric kettle, a vacuum cleaner - and this is not a complete list of electrical equipment that are today an integral part ...

Each of us is familiar with the situation - at the most inopportune moment, the electricity is turned off. In the optimistic version, you just have to do without a hot lunch or spend an evening by candlelight. It is much worse if you worked at a computer and problems at the substation negated many hours of work.

How to protect yourself from power outages? This method has long been. The line filter or stabilizer can protect against unexpected power surges, but they are useless if the light is turned off.

Uninterruptible power supplies (UPS / UPS - in English) will not only provide uninterrupted power supply to your computer and peripheral equipment, but, often, they can replace the stabilizer. First of all, determine for what purpose you need an uninterruptible power supply. Fifteen years ago, my first computer UPS ...

Let's face it - a universal answer to this question simply does not exist. Each case must be considered individually. The thing, first of all, is that each energy supplying organization offers its services at separate tariffs and offers technical conditions for connection, based on the characteristics of its network.

Thus, the simplest option is the case when your site is located in the city with a finished power line on the street. If at the same time the distance to the power transmission line in a straight line does not exceed 25 meters, then the issue is solved very simply - you do not even need to install additional support. In accordance with the technical conditions, only a simple branch made by a self-supporting insulated wire using special fittings will be enough. In other cases, you can refer to the document, which is known as the decree ...

If the light goes out in the apartment, the sockets are turned off, or the electric stove stops working, then any person who is familiar with electrical engineering goes to the site to check the condition of the circuit breakers in the electrical panel. Most often, troubleshooting is reduced to restarting the machine.

The fact of operation of a modern modular circuit breaker is easily determined: the handle is in the "down" position, a round sign - "zero" is clearly visible on it. To turn it on, simply turn this knob up, then a horizontal line will appear, and we can assume that the mission has been completed.

Many apartments in the former Soviet Union are equipped with guards with automatic machines of a slightly different type. AE series circuit breakers and the like have slightly larger dimensions, are attached to the base with long screws and have an unpleasant property ...

At one time, the leadership of our country committed itself to providing each family with a separate apartment. It is clear that before and after that, many different beautiful promises were made, and our state has become completely different. However, they tried sincerely to fulfill the promise about individual apartments. Great hopes in this matter were assigned to the technology of building houses from panels.

Panels are prefabricated reinforced concrete products. At the construction site itself, it remains only to assemble them according to the principle, not far removed from the principle by which children's designers gather.

The technology is really fast, but the same type of panel houses were not the best option for people to live.Low noise insulation, a large level of heat loss, low durability ... But we, in fact, want to talk not about the disadvantages of panel housing ...
