Is it possible to install the air conditioner on my own? Undoubtedly possible, provided that the air conditioner is a monoblock design. And, here, installing in-house air conditioners, such as a split system or, moreover, a multi split system, given that they respectively consist of two or more units, is at least not practical. The reason for 90% of breakdowns arising in them is precisely unprofessional installation. Repair is expensive.

Generally speaking, the installation of air conditioners is a very responsible matter and it should begin with determining the location of the device. If the air conditioner is monoblock, it is easy to install it in a window opening with a slight slope outward for gravity removal of condensate ...

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 the one your cable branch with a machine is designed for. 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 whole repair does not boil down to plywood 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 Rules of Electrical Installations (Clause 2.1.21): connection, branching and termination of conductors 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 conductivity of the contact.

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 work ...

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 ...
