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 ...

For most of its inhabitants, the electrics in an apartment are, first of all, numerous switches and sockets. As a rule, there are too many of them. But neither sockets nor switches are hanging in the air - they need to be somehow fixed to the wall.

Sockets and switches are of two types: for hidden and for open wiring. Accordingly, the method of installing sockets and switches depends on the method of wiring. The final choice of devices for installation, that is, reinforcement, also depends on the material of the walls on which the installation is carried out. Under certain conditions, it is even possible to install, as they say, “without everything,” that is, simply onto a wall.

So, we will consider how to install sockets and switches depending on the type of wiring. For hidden wiring the main thing - the material and quality of the walls. If the wall is flat and non-combustible, such as brick or concrete, or if it is tiled ...

How and where is the best place for sockets and switches.

Everyone, sooner or later, thinks about repairing a house, an apartment. When planning a repair, the question arises about the location of sockets, switches, lamps. As a rule, during repair, the old wiring is completely replaced with a new one. In this article, we will consider options for the most optimal placement of sockets and switches.

There are no uniform rules, standards and formulas for determining the number of outlets. Each apartment, each house with its inhabitants is individual and requires an individual approach to determining places for the location of sockets, switches ...

Most manufacturers of sockets, switches spend considerable money on ensuring maximum security for ordinary consumers and raising the level of comfort during the operation of electrical appliances.

For example, many manufacturers equip their sockets with protective curtains. It will not work to insert any foreign object other than the plug from electrical appliances into the outlet of the outlet.

These sockets are ideal for installation in apartments where young children grow. For the curiosity of the kids is no secret to anyone, many of the kids constantly strive to stick something into the socket outlet. In addition, recently, almost everyone who makes repairs install sockets at a level of 35-40 cm from the floor. The presence of curtains also serves as additional protection against ingress of foreign objects, dust, moisture into the outlet mechanism ...

Circuit-breaker circuits allow turning on and off lighting from two or more different places for their installation. In some cases, this is not only convenient, but also very necessary.

For example, there is a long corridor. It is naturally lit.Turning on the light at the beginning, and having this very scheme of connecting the passage switch, you do not have to return again to turn it off, but you can do this with the second switch that is installed at the other end of the corridor.

Let's take a closer look at this wiring diagram, consisting of two loop-through switches. It will require two switches (they are also called “walk-through”), each of which has three contacts and two switching positions. Moreover, the switching mode must be of "cross over nature", that is -one contact is common to the other two.In one position it is closed with one of them, and in another position, naturally, with another ...
