First you need to decide what a warm floor is and why it is needed. The warm floor is not just a device that allows you to walk without shudder on the tiled floor of the bathroom in the early cold morning. This is a room heating system, which in some cases can even be primary, rather than auxiliary.

Moreover, heating a room with underfloor heating has a number of advantages compared to radiator heating. So, heated air near the floor surface retains a feeling of warmth and comfort, and colder in the upper part of the room provides freshness at the required humidity level. In a word, a warm floor is a favorable microclimate in an apartment or a room. There are two options for installing a heated floor in a country house: water and electric underfloor heating. In the article, we will consider in detail the option of installing an electric floor heating ...

On the one hand, wiring accessories for a country house are well-known sockets, switches, stationary lamps, frames, socket boxes and the like. But, on the other hand, a country house differs from a template city apartment in that it always has some individual features. Speaking differently, usually at the construction stage, the owner of a house decides what exactly should be in his own house from the electrotechnical benefits, and no one restrains him in this.

The riot of fantasy of the future homeowner is limited only by the size of his wallet. Therefore, in a country house you can often come across some kind of wiring exotic. In addition to the already familiar floor heating and recessed fixtures, a wide variety of sensors, buzzers, surveillance cameras, thermostats and even frequency converters and other complex electronic devices are increasingly being installed ...

The installation procedure for wiring in a country house depends on the type of wiring itself. Hidden or open - the choice of one or another option determines all the technology and all the difficulties that a homeowner will have to go through when electrifying his country residence.

Open wiring, the installation of which is connected with the direct laying of the cable on the walls and ceiling, has long become an anachronism and a thing of the past. If the house is wooden, with a deliberate lack of interior decoration, then such installation is contrary to the rules of fire safety. And in all other cases, an open cable routing openly spoils the interior. The latter applies to open wiring in corrugated and smooth pipes. Therefore, open wiring in country houses is usually performed in plastic cable channels. According to the color of the interior, you can choose the appropriate box ...

Internal wiring in country houses is most often performed open. Since the interior decoration in these houses usually includes decorative elements and natural wood paneling, the most typical route for laying the cable is a plastic cable channel. After all, the open installation of cable lines on combustible surfaces is prohibited by the applicable PUE standards. At the same time, open cable laying in pipes or corrugated pipes on clips is rejected for aesthetic reasons.

Regarding the choice of cable products for wiring in a country house, we can say that it is not particularly wide. In order not to have any problems afterwards, it is better to stop on VVG-ng copper cables (for those who want to save a little), or NYM (for those who are not limited in funds).The chains of sockets are traditionally made with a cable with three conductors with a cross section of 2.5 square meters. mm., and the lighting circuit ...

The need for a re-earthing device at the entrance to the country house is dictated by the current regulations of the PUE. In accordance with paragraph 1.7.61 of these rules, it is recommended to install a grounding device with a current spreading resistance of 30 Ohms for a three-phase network and 60 Ohms for a single-phase network at the input to any electrical installation of the TN grounding system. These recommendations can be neglected only in the case of the presence and use of natural grounding conductors (metal structures partially located in the ground and meeting the requirements of the PUE for resistance).

Since it is far from always possible to choose a suitable natural grounding conductor, the device of a separate grounding device (charger) at the entrance to the newly built country house becomes the most rational technical solution. Moreover, it does not require special material costs. The grounding device includes a grounding conductor ...

The place of concentration of all electricians in each house or apartment is a house electrical panel. It is here, with the help of various equipment, that the distribution of electrical energy in your home takes place. And the house electrical panel of a country house fundamentally differs from the apartment panel only in the size and number of devices.

The equipment that is part of the modern home electrical panel is modular and mounted on a DIN rail. This saves space, especially if you take into account the fact that home electrical networks are often three-phase, and there are more than enough powerful household electrical appliances in a country house. For the same reasons, home electrical panels often have several tiers, and the total number of modules of equipment placed in them reaches 36 or more. This equipment includes: opening circuit breaker ...

Power supply of country houses has a number of distinctive features. The main one is the need to connect to the overhead line (VL). The burden of arranging this connection is usually the responsibility of the owner of the house, and the point of connection between the power supply organization and the homeowner is the point of connection to the overhead line.

When the branch device is installed, additional installation of one or several supports may be necessary if the distance from the entry point into the house to the overhead line is more than 25 meters. The input itself should be located at a height of at least 2.75 meters, and the wall passage should be made in accordance with fire safety requirements. We are talking about the presence in the wall of a mortgage tube made of non-combustible material, as well as the compliance of the lead wire cross section with the maximum permissible load, taking into account the stock. It is best to use SIP as an input conductor, although the use of VVG or bare wires is not excluded ...

When we hear the phrase “old wiring”, a very specific image pops up in our memory: two thin aluminum wires in common single-layer insulation with a wide and flat separation gap. Since the insulation is common, the phase and zero conductors, of course, do not differ in color. What brand did that ever-memorable cable have? And it’s hard to remember, although it is still on sale today. Of course, we do not recommend using it.

Today, we can rightfully say that aluminum in household wiring has already outlived its own. This is confirmed by the rules of the PUE prohibiting the installation of aluminum conductors with a cross section of less than 16 square meters. mmBut even without these norms, it has long been known that aluminum wires always form a film of non-conductive oxide on their surface, which often causes overheating of contacts. The mechanical properties of aluminum from overheating become even worse ...
