Now, thanks to the efforts of our Chinese brothers, various electronic devices are increasingly penetrating even into household wiring. These are various electronic calls at the front doors, Christmas lights and garlands, sockets and switches that are triggered by a television remote control, devices for extending the life of incandescent lamps (delay when turned on), photo sensors to turn on lighting, electronic transformers to power low-voltage halogen lamps, spotlights with motion sensors and more.

Energy-saving lamps, popular recently, inside their base have a simple electronic circuit with only two transistors. And fluorescent lamps, remember, those with roaring chokes and blinking when turned on? Now, instead of chokes, electronic ballast is used ...

Any sane person, before making any serious purchase, must determine the basic criteria that this product must meet. For example, when purchasing a refrigerator, you decide whether you need a freezer in it or not, the internal volume of the refrigerator, etc. The same goes for mini power plants for the home.

In this short article, we will consider the main points that you need to pay special attention to when choosing a generator.

So, the first thing you should pay attention to is, of course, the power of the generator. Not only the final cost of the generator set, but also the reliability of the entire power system of the house depends on how correctly and correctly you calculate the necessary load in the house, powered by a generator ...

Many believe that it is easier to take and change the lamp to a new one, but this is not so - their quality does not get better over time and even expensive models have problems with electrics even if only because their manufacturers themselves do not produce wiring accessories. Therefore, it is worth a try.

I want to start with a simple one: repair of fixtures in which shades are mounted with union nuts to an external thread on the cartridge housing. There are a lot of such lamps now, both single-lamp and multi-track chandeliers. There are with cartridges E27 and minions E14, I will start with the latter.

Now on sale and in use there are a lot of diverse and sometimes quite beautiful chandeliers with 3-9 horns and more for minions with such a ceiling fixture. Cartridges, usually plastic, are not of the best quality: initially or over time, contact with the base in them becomes completely bad ...

With a switch, light or socket, each electrician searches for the shortest path to the nearest branch box. This is understandable: I want to save on the cable, and nobody wants to do the extra work on laying it. Therefore, boxes in each apartment are usually enough: up to two or three in one room.

But still, the main purpose of branch boxes is not to save materials and working time. Their most important function is to protect the cable core connections from external influences: from dust, moisture and mechanical damage.

In fact, no matter what we use to connect the cores of wires, all the same, the places of these connections look so defenseless - the factory insulation is stripped, both internal and external, and the integrity of the conductors is broken. Without proper protection, dust or moisture can block the connections ...

The reliability of modern household electrical appliances is clearly poor. The older generation recalls with a sigh the iron that was ironing for 10 years, the TV, which worked for 15, and the refrigerator, which also served as a grandmother. Examining objects of past years in the museum, their massiveness and strength are striking in comparison with the current flimsy and graceful.

It is difficult to say why the reliability of household appliances is decreasing every year. Probably because manufacturers choose cheapness between low-cost production and quality, even the most famous and trusted companies sin by using components from other manufacturers or even transferring production to Asian countries.

Thus, the purchase of a household appliance has long turned into a lottery. If you are lucky, it will serve for a long time, but if not? ...

A generator set is a backup source of electricity, which is turned on (or turned on) when the main electricity fails and the necessary load is connected to it (generator) - a house, office, enterprise.

Starting, stopping and connecting the load can be done in two ways - in automatic and manual modes.

In this short article, we will try to talk about how to independently automate the entire process of turning on and off the generator and how to connect the ATS to the generator itself.

For the normal and correct operation of the “generator-ATS” link, you must understand the operation algorithm of both the generator and the ATS, namely, all the time parameters of the generator and the ATS, what should be turned on and when ...

In principle, it is not so important, you use ordinary incandescent lamps or halogen lamps or even compact fluorescent lamps - the lamp must be in any case working!

The main problem of modern luminaires is wiring accessories and, often, wiring (internal wiring in the luminaire means, not the one in the walls). Regarding wiring products, we can briefly say that over the past fifty years they have become, alas, worse and worse.

With regard to luminaires, this applies primarily to lampholders (as well as switches, including those built into luminaires), and they not least affect the lamp life. On cartridges it is worthwhile to dwell in more detail. In household fixtures, mainly lamps with threaded caps are used ...

About the main and additional potential equalization systems and their functional purpose.

Residential building. Many floors and apartments. Entire kilometers of communications: wires, metal pipes, ventilation ducts, metal hoses and the like. In our apartments there are various metal bathtubs, sinks, heated towel rails and you never know what else. In other words, the whole house is simply full of elements and structures capable of conducting electric current, but often not intended for this.

However, each conductor has electrical potential. This is just the law of physics. Potential is a relative value. This means that the electric potential of, for example, the metal surface of the refrigerator in itself does not matter at all. It is important how much higher or lower the potential ...
