Why does the outlet sparkle? And the socket can glow. An uneven, twitchy, but rather bright light. But this light does not inspire others with any optimism and does not create any festive mood.

On the contrary, in people far from electrical engineering, such light causes superstitious, almost primitive fear. Almost like before thunder and lightning from our ancestors. Moreover, the nature of sparking in the outlet is the same as that of a lightning discharge of atmospheric electricity. And even “thunder” is present - in the form of dry cod.

It may, of course, not be afraid, but it is still worth fearing a sparkling outlet. And to remain indifferent, if such a "fun" outlet wound up in your apartment, it should not be. The temperature of the electric arc, which are the outlet sparks ...

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 outlet and one lamp.

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

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 electrical 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 with 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 ...

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 harness of these wires is sometimes more than impressive, especially in places connected to the apartment switchboard.

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 construction pencil and level ...

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 electrical wiring, each of which we will try to dwell on. The first and most important requirement is the fire safety requirement ...

For those who often spend their holidays outside the city or live in the countryside, the problem of constant voltage drops in the power grid has long been known. She is very annoying because often leads to failure of both lighting and large and expensive appliances such as refrigerators, microwave ovens, air conditioners, etc.

There are many ways to deal with the unsatisfactory quality of the voltage in the mains, but probably the easiest is to install a voltage stabilizer. Such stabilizers are common house (high power) and local, i.e. low power for a specific device. If you have enough money, then an all-round stabilizer is preferable, because It protects your entire home, not just a specific appliance.

The first thing to do before choosing a stabilizer is to determine its power. Ideally, it should be 30 percent higher than the total power of all your electrical appliances ...

When installing and arranging the lighting of residential premises, the uniformity of lighting is always in the first place for the consumer. That is why spotlights, LED strips and neon light tubes have become so popular today - their light is not concentrated at one point, does not hurt the eyes and eliminates the appearance of shaded areas.

But with all this, well-known to all of us chandeliers, located on the ceiling in the center of the room, have not lost their positions. On the contrary: the variety of forms and design designs of modern chandeliers is simply amazing.

And, in the end, the need for general lighting of the rooms has not yet been canceled, and a more successful and beautiful solution to this issue than a chandelier has not yet been invented. However, the installation of chandeliers has a number of specific features, which we will try to talk about ...

According to the classification adopted in the PUE, the bathroom in any apartment is, if not particularly dangerous, at least a room with increased danger. This means that the likelihood that a person will be shocked in the bathroom is high, and the consequences in the event of such a shock will be more severe.

Higher danger implies greater responsibility and requires us to take additional safety measures when installing and installing the electrical wiring of the bathroom. For rooms with increased danger, the following measures are recommended: the use of protective grounding, the introduction of a third, protective conductor PE, the use of devices for protection against leakage currents - RCDs or differential circuit breakers.

For bathrooms, both measures are mandatory. Many also consider the requirement for a hidden wiring device in the bathroom ...
