Even if you do not intend to do electrical wiring in your apartment yourself, it would still be nice to know about some of the nuances of this business.

The electrical wiring in the apartment begins with an electric meter. Automatic machines follow. They automatically turn off the electricity as a result of short circuits and overload in the mains. A cable runs from each machine into the apartment, onto which all sockets, switches and chandeliers are already “hung”.

Overload in each cable branch occurs if you turn on devices whose power is greater than that for which your cable branch with a gun is designed. When purchasing electrical appliances, always read in the description how much power they consume. To determine what power your wiring is designed for ...

Apartment renovation is not done every day. But when you finally decided on this, the question itself arises, and who will do this repair? Most likely, you will have to hire someone, of course, if the entire repair does not boil down to plywood the wallpaper in one room or hallway. And here two options are possible - a private trader or a construction company. But in any case, one may encounter dishonesty and low qualification of the masters.

The fact is that even construction companies hire specialists, in general, the same. As a rule, among those who advertise in the local newspaper, stands at construction stores offering services, or simply sticks on the poles ads with their phone numbers ...

The use of fiberoptics, or more simply, fiber optics, to illuminate personal plots, is becoming increasingly popular today. Despite the high cost of this type of lighting fixtures, more and more people opt for them. And there are objective reasons for this.

Firstly, an optical fiber is absolutely fireproof, since it is not a light source, but a light-conducting medium. Secondly, the capabilities of light filters, which easily allow you to change the color of light, create a simply amazing effect. Thirdly, the fiber optic cable is completely sealed, which gives truly unlimited possibilities when choosing its location. Fourth, this type of cable is flexible and very heat resistant ...

According to the Electrical Installation Rules (p. 2.1.21): connection, branching and termination of wires and cables should be performed by crimping, welding, soldering or clamping (screw, bolt, etc.) in accordance with applicable instructions.

No matter how convenient (for lazy people) methods of connecting wires, they did not come up with, none of them can be compared with welding in terms of durability and contact conductivity.

Even soldering breaks down over time: there is a third, more fusible and friable metal (solder), transition resistance always exists at the interface of different alloys, and chemical destructive reactions are possible. The duration and complexity of high-quality soldering is not inferior to welding ...

The first question that everyone asks when faced with the need to repair their home is how much it costs to make repairs.

Construction companies and teams offer three main repair options: cosmetic, overhaul and European-quality repair.

The cheapest - redecorating. This, roughly speaking, where to tint, where to smear, where to glue the wallpaper. In general, it’s just to refresh the atmosphere, you look, it’s already happier to live. Such repairs are not difficult to do on their own, then its cost drops to the cost of materials.A private master will take about $ 25 for work per m2, the company will cost up to 60 cu per m2 (floor area) ...

In addition to those described earlier methods of connecting wires, welding has been widely used recently. Welding is preferable to all others: it is easiest to get a reliable and high-quality contact with it. Therefore, the uptime of the wiring is very long.

Now the wiring is most often performed by a copper wire, they try not to use an aluminum wire. Therefore, further we will focus mainly on the welding of copper wires.

Welding of copper wires can be done either by alternating or direct current at a voltage of 12 - 36V, while it should be possible to control the welding current. The most suitable for welding wires should be considered an inverter type welding machine ...

The article describes the various methods of connecting wires when wiring.

The wiring device requires a reliable connection of wires. In the sixties and seventies of the twentieth century, during the construction of the "Khrushchev" houses, wiring, purely for economic reasons, was carried out with an aluminum wire.

All connections in this wiring were made by the method of twisting, which were isolated with black cloth tape, and could last ten or more years without requiring any maintenance or prevention. Of course, if the twisting was performed according to all the rules. Therefore, old electricians argue that there is simply no more reliable twist, no connection ...

Film floor heaters have obvious advantages over cable heaters:

1. Installation of a film heat-insulated floor is carried out in just a few hours.

2. There is no need to open the floor.

3. There is no need to make a screed.

4. The film heater can be installed under any coating: laminate, parquet, linoleum.

We examine the system of film insulation material for the floor. Its central thickness is approximately half a millimeter. A similar heater is made from glued dacron films. Between these films are conductors (silver or copper), and a heating graphite element ...

Hybrid cars are becoming increasingly popular all over the world. This is caused not only by their fuel efficiency, but also by environmental requirements, which are constantly being tightened, and hybrid cars reduce emissions of unburned hydrocarbons and nitrogen oxides into the atmosphere by 85%.

Most hybrids currently have two engines. This is an internal combustion engine (hereinafter ICE) and an electric motor. An electric motor, as a rule, has less power than an internal combustion engine, but still, it requires heavy batteries or fuel cells to operate. They take up a lot of space in the car and increase its weight. For example, Toyota Prius II, which is considered one of the best hybrids ...

A detailed description of the selection and installation of an electric water heater in the apartment

Disruptions in the supply of hot water to our apartments and houses often occur, and in some cities and regions it is simply regular and this causes great inconvenience to many families.

If the house has small children, then the lack of hot water from a small temporary inconvenience turns into a real problem. However, solving this problem is quite simple and not even too expensive by installing an electric water heater. To begin with, we will determine what principle of action needs a flow or storage heater.Instantaneous electric water heater costs less ...

The modern elemental base of electronics allows you to create devices simple in circuitry, but having a fairly wide range of functions. Previously, such devices were only available for use in complex and expensive professional systems, and now their use makes our everyday life more comfortable and easier.

This article will talk about devices that use sensors that respond to infrared radiation. Once such sensors were mainly used in security systems, now no one is surprised by the doors that open in front of each incoming person or the automatic inclusion of lighting in the entrance. And all these are infrared sensors! ...

This is my first article, I am just starting, so please do not judge strictly.In this article, I will share my personal experience and tell you how to conduct light on a glazed balcony. Simply, if it is not glazed, then why is there light?

When there is a window frame on the balcony, there are plans to sheathe the walls with a rail, to insulate the floor, light in this room is simply necessary.

So, you need to hold the light on the balcony. Where to begin? With an assessment of the situation. From which the bulb will be powered by electricity.

If the house is old, then all the wiring is in the ceiling plate and only there, look for the power cable and pull it from the balcony. As a rule, all ceiling twists, it is better not to touch, but for good, change the wiring completely in the whole apartment to copper. What to do? And let's eat from a regular outlet! Is there such a thing? Still not far from the balcony? Here is the solution! ...
