Views on the arrangement of housing for an iron horse in people are very different. For someone, a garage is a place where you can simply lock the car without fear for its safety. And to someone, the same garage seems almost a sacred place where you can dig deeper with technology, save potatoes in the winter, and drink beer with friends in the evening.

Accordingly, the electrical wiring in the garage must be arranged in accordance with the requirements of the owner. If the garage is unheated, if its owner plans to repair and service the car only at car services, then he probably does not have a viewing ditch. Most likely, the maximum that is required in the garage for such a motorist is one socket and one lamp.

A more advanced car owner will definitely install several lights in the garage, powered by different switches and lighting ...

How much power should a generator be for a home? Power is a significant characteristic, which depends on the number and types of home electrical appliances.

It should be remembered that, for example, refrigerators and air conditioners, as well as other cooling and heating devices, consume a lot of electric energy and need a powerful generator. But a small power unit will be an ideal solution for those who need a power source, say, for external lighting of an object.

What happens if you accidentally “overload” the generator? It must be borne in mind that if the generator has been operating for a long time exceeding the maximum permissible operating mode, engine overheating is possible. In addition, the integrity of the oil supply system may be impaired, which may contribute to a decrease in pressure ...

How often do you use electricity? I agree, the question is somewhat strange for a modern person, and one would expect a completely logical answer - constantly, but nevertheless, having enveloped their homes with wire meters, not everyone thinks about alternative sources of electricity. One of such sources under the name "indigirka" will be discussed.

The company "Thermofor" in cooperation with the St. Petersburg company "Crioterm" decided to combine a thermal electric generator with a long-burning furnace, obtaining a solid fuel heating and cooking stove, and thereby giving people the opportunity to reduce their dependence on standard wiring.

The Indigirka stove is the only solid fuel heating and cooking stove in the world that is capable of generating electricity during operation ...

In the laboratory stands of my college, laboratory autotransformers (LATRs) regularly fail. It so happened that through trial and error I was able to master the technology of their repair. At the moment, I have managed to repair three laboratory autotransformers, and I did this in my room in the dormitory. I would be glad if the LATR rewinding technology described here is useful to someone. Yes, this is my first article, so do not judge strictly :-)

To begin with, a short course of the LATR device. LATR has two windings connected in series. Mains voltage is applied to the primary winding (this must be taken into account when rewinding). The secondary winding is connected to the primary. It is designed for voltages from 0-240 V. Voltage is applied to terminals A and N in the magnetic circuit, a magnetic flux is created which induces current in the windings ...

A conventional switch is not suitable for switching on a load of 2 kW or more. The article talks about how to solve this problem.

What needs to be done to turn on the light bulb? Just flip the switch. Nowhere is easier. Well, what needs to be done to turn on the five-kilowatt boiler? Also click the switch? Alas, if this switch is connected directly to the power circuit, then it will exist for a very short time. His contacts are designed for a maximum of 10 amperes maximum. Even if you consider that the switched load is purely active and the power factor is close to unity, these 10 amperes will amount to only two and a few kilowatts for a single-phase load.

Not really something and you will run into such a reserve for power. And what to do? After all, power receivers with a capacity of more than two kilowatts are not so rare in everyday life ...

There are many different ways to solder radio components from circuit boards with a view to their further use. Of course, preference should be given to professional techniques and devices for the dismantling of radio elements. However, it is unlikely that professionals with serious special equipment need transistors, resistors, and other amateur radio tricks obtained in this way.

So we will talk, of course, about home technology. And more precisely, I would like to share just a couple of simple tricks that will certainly accelerate this desired process. So, we will talk about the procedure for extracting the necessary parts from old boards or boards that are not intended for further restoration. I’ll make a reservation that we are not talking about chip desoldering, they need a thinner approach ...

Perhaps the most time-consuming way to install electrical wiring is to lay it in pipes. But there are times when it is simply impossible in a different way. For example, hidden wiring in wooden houses is best done in pipes, and not in a corrugated pipe, as is customary.

The pipe provides reliable protection against mechanical damage, but under certain conditions it can also protect the cable from aggressive environmental conditions. It all depends on the material of the pipe and the method of joining its individual segments.

So for dry rooms without increased danger it is quite possible to use a steel thin-walled pipe with a cross section of 15-20 mm, connected using sockets or threadless couplings, as a route for electrical wiring. Moreover, if the pipe is open, then it must be painted, and if the pipe goes under concrete pouring, it is better to refrain from painting ...

We all know, torn where thin. The same is true in the electric circuit - in emergency conditions, the breakage occurs primarily at the junction of the wires, and not in the wire itself.

This happens due to the appearance of transition resistance at the junction of the wires, therefore, the better the contact, the lower the resistance, the more reliable the electrical circuit. In home wiring, probably in 90% of cases, connections were previously made by bundles of wires followed by soldering or welding, but often just like that.

Sometimes used and bolted connections, terminal clamps. But science does not stand still and self-clamping terminals were invented to help electricians, now they are also called Wago clamps. Work has become easier, more fun, when you disconnect in the electrical distribution box, know how to insert wires into the terminals ...

In the vast majority of cases, when installing a hidden electrical wiring, one can not do without such a dirty and noisy procedure as gating.

Wires and cables must be hidden, but how to do it without a gate, if we just have a plain wall of concrete or brick? Moreover, the bundle of these wires sometimes turns out to be more than impressive, especially in places of connection to the apartment distribution board.

Strobing and laying of cable harnesses must be taken care of long before the final decoration of the room: it is when the apartment does not yet have a trace of furniture, no items, no wallpaper, no linoleum, nothing at all. In a word - bare walls, as in one famous TV show. On these bare walls, we determine and mark the route along which cable lines will run through us. Marking can be done with a building pencil and level ...

Theoretical calculations and practical comparisons of various light sources, the use of LED lamps.

The issue of energy saving is still one of the first places in the family budget. One of the areas of economy is the economy of lighting. And here some progress has been outlined.

The news is associated with lower prices for LED lamps. Now these devices can be bought at a price of less than 300 rubles apiece, i.e. they came close in price to energy-saving fluorescent lamps that became popular among the people.

Compare different light sources. In order to understand what LED lamps can and cannot do, you need to compare how much light different types of lamps give out per watt of energy consumed, i.e. light output. The starting point for us will be an incandescent lamp, as the most famous standard ...

The device (in a few words), advantages and disadvantages. Lead-acid, nickel-cadmium, nickel-metal hydride and lithium-ion batteries.

Battery technology quietly and firmly entered our lives. Cordless phones, cell phones, cordless power tools, cameras, a variety of toys ... If all this received electricity only from ordinary acid or alkaline batteries, then a significant share of the budget of every Russian family would be spent on batteries. Therefore, you often catch yourself thinking: how did we even live without household batteries before?

Batteries are electrochemical devices capable of storing and delivering electricity. However, behind such a simple definition lies a wide variety of designs and principles of operation of various batteries ...

It should be noted that there is simply no clear and unambiguous separation of electrical wiring into hidden and open. There are two different opinions: some consider hidden only that wiring, the route of which is not visible, it is impossible to trace. At the same time, others believe that the wiring in the pipes and cable channels should also be hidden, since the cable is not visible, and it is mechanically protected.

We will not break copies on this subject. Let's talk only about the wiring, which everyone considers hidden. According to the method of laying the cable, it can be divided into wiring laid in the strobes, and wiring mounted under any sheathing. In one room, these methods of cable laying can very well be combined.

Well, and, of course, a number of requirements are imposed on hidden wiring, each of which we will try to dwell on in detail. The first and most important requirement is the fire safety requirement ...
