In this article we will analyze in detail all the subtleties of the process of the device in the apartment of the new electrical wiring. This work can be successfully carried out independently. But, before starting work, it is very advisable to start objectively assessing your real capabilities, since installing electrical wiring in an apartment is a complex process and certain knowledge and skills are necessary for its successful implementation.

Cable brand selection

1. Each core of the wire must be rigid (single core), because all sockets and switch are designed for installation with a hard wire.
2. The choice of brand of occasion. Three types of wire are mainly used: NYM, VVG, PUNP.
NYM cable is a cable with copper single-wire conductors with reliable triple insulation.
The first layer is PVC, the second layer is a rubber sheath, the third is each copper core in PVC. But this wire is not without flaws. It is not recommended to be placed in raw concrete and carried out outdoors, it has a large diameter and is quite expensive.
But, if you do wiring in the apartment and want something more reliable, then take, of course NYM.
VVG cable - cable with copper single-core conductive conductors, with insulation from PVC compound - value for money. It has double insulation: common PVC and each core in PVC. VVG can be laid anywhere: both on the street and in concrete. Isolation is slightly worse than NYM, but better than PUNP. If you do not need extra expenses, we select the simplest and most commonly used PUNP wire ...

The most significant in car batteries are the following three indicators:

Firstly, it is a capacity expressed in ampere hours. It characterizes the ability of the battery to give a certain current for a certain time. For example, a capacity of 40 ampere-hours means that the battery can give a current of 1 ampere for 40 hours (or 2 amperes for 20 hours, etc.)

Thirdly, reserve capacity. This parameter, especially revered in America, shows the time interval (in minutes) during which the battery is capable of delivering a current of 25 A (i.e. for how long it can replace a failed generator).

What is inside?

A standard car battery consists of six 2-volt cells, which gives 12 volts at the output. Each element consists of lead grating plates coated with an active substance and immersed in an electrolyte. Negative plates are coated with finely porous lead, and positive plates are coated with lead dioxide ...

August 18th. Today, I finally ran the cable through the wall adjacent to the neighbor from the corridor distribution box to the outlet in the hall. To do this, removed the old wires from the channel. To one of them fastened a cable. In general, for this I advise you to purchase a cable in PVC insulation. I took a chance without. I hooked one cable core to the cable, squeezed out the rest so that they would cling and use the pull-and-push method, and by dashes from the corridor to the hall pulled the cable in the hall.

Now I just have to drill the gate from this socket to the left on the end wall (I did not have a corner apartment and sockets on this wall). After that I will put the socket outlets, and tomorrow I will proceed with the installation of the socket group in the distribution boxes.

August 27th. All! I - an unprofessional electrician, finally managed to change the wiring! No more tripping over extension wires! Further without emotions. Today I connected the wires in the junction boxes ...

I work in Convir as a system administrator and programmer. It so happened that our office, laboratory and production are located in different places.I am sitting, generally, on Preobrazhenka in a small room. But not far from home, and Internet communications are just excellent, with inexpensive traffic.

My side is sunny. Depending on the weather, it’s hot, then cold. I put the air conditioning in the window, and then during the heat I was not up to work. To make it cheaper, the air conditioner bought flowing (180 cu), at the same time, it ventilates the room, in contrast to the split system. I don’t open the windows now, there is less dust!

In general, everything is fine, only with this air conditioner is a hassle. He has no remote control. He is so simple. And it stands above and it’s inconvenient to climb to it. Again some kind of ambush. All these problems with climate and lighting are very distracting, and for me to focus is a big problem. I somehow began to think about it all the time. Well, I came up with ...
