For wiring of a hidden type, as a rule, it is necessary to install sockets of the corresponding type, that is, hidden. Very often there are external outlets in the apartment. Perhaps, when installing the wiring, the previous owner of the apartment or an electrician performing work to replace the wiring decided to save his time and installed an outdoor type socket. He greatly simplified the work, since he did not have to mount the box directly into the wall for mounting a hidden socket.

The external outlet does not fit into the interior design of the apartment, since its entire body is located outside the wall. At this stage, the landlord decides to fix this problem and install a hidden socket, that is, an internal one. How to replace an external outlet with an internal one? First, you need to prepare for the work ...

We encounter electrical outlets every day, so it is very important that they are convenient and reliable. A lot depends on the correct choice of the outlet. Firstly, it is an opportunity to fully satisfy their needs in the inclusion of electrical household appliances. In addition, its service life depends on the correct choice of the socket.

When a person does not know the basic rules that must be followed when choosing an outlet, he often faces the problem of frequent failure of outlets. Perhaps, in this case, the outlet simply does not correspond to the actual load parameters of the household appliances that are included in it. Therefore, you need to know how to choose a quality outlet. We will talk about how to do this correctly in this article. At the moment, the range of sockets is very large. In this case, your task is to choose a quality outlet ...

Getting acquainted with the NooLite line of modules from the Nootehnika company, one does not leave the feeling of admiration mixed with distrust. Do these toy, small devices, costing less than a common magnetic starter, have such an impressive array of capabilities? Nevertheless, the NooLite system, which the manufacturer positions as specialized for lighting control, incorporates modern ideas, and it is implemented at a high technical level.

We will consider the capabilities of lighting control modules using the example of several representatives of a line of blocks whose nomenclature is constantly expanding. These are two control panels (transmitters) PU212-1 and PU313-1, power blocks (receivers) SN111-300 and SL111-300, and for those who like to manage everything from a computer, the adapter for the PC118 computer. The design of the transmitters is identical and designed for stand-alone operation in any convenient place ...

In the era of actively developing socialism, plug sockets in the bathroom were considered unnecessary and unnecessary luxury. Therefore, it is hardly possible to see somewhere "Khrushchev" with "native" outlets in the bathroom.

But life does not stand still, and the Khrushchev’s are still in operation. And today their owners are increasingly faced with the need to install electrical outlets in the bathroom. It is necessary to connect washing machines, showers, hair dryers, electric shavers and, possibly, some more rare and even exotic types of electrical appliances.

Due to the stereotypes that have developed over decades, sockets in the bathroom were perceived by many electricians as something unnatural: “How so? High humidity, splashes, steel pipes of hot water and cold water, cast-iron risers, and sockets nearby? It’s not just dangerous, but very dangerous! ” ...

In this article, we will consider a device that is sold in electrical goods stores as a dimmer control. It's about a dimmer. The name "dimmer" comes from the English verb "to dim" - to darken, become dull. In other words, a dimmer can adjust the brightness of the lamp. Moreover, it is remarkable that the power consumption decreases proportionally.

The simplest dimmers have one rotary knob for adjustment, and two terminals for connection, and are used to adjust the brightness of incandescent and halogen lamps. Recently, dimmers have also appeared to adjust the brightness of fluorescent lamps.

Previously, rheostats whose power was not less than the load power were used to adjust the brightness of incandescent lamps. Moreover, when lowering the brightness, the remaining power was not saved in any way, but was dissipated useless ...

The choice of sockets for stoves and washing machines. The selection is made according to some basic operating parameters. Here they are:

1. The number of phases required to power the electrical receiver, that is, its "phase". In any case, a three-phase connection requires a socket with five connectors: L1, L2, L3, N and PE. A single-phase power supply is enough for a socket with three connectors: L, N and PE. Three-phase in our case can only be a stove, and even then only if it is possible to connect to a three-phase network.

2. The rated current load on the outlet. The passport of any device usually indicates electrical power, and data on the current drawn from the network may not be available. But electric power is never indicated on the body of electrical outlets - there is only information about the maximum permissible current ...

Sometimes it happens, you go into the room, turn on the light, and the light does not shine. Replacing the lamp does not help. If in other rooms all the lights shine normally, then most likely the switch has broken. If it is not possible to call an electrician or sufficient funds to pay for his services, you can replace the light switch yourself.

To replace the switch, you will need: a screwdriver, a phase indicator (indicator screwdriver), a new switch, pliers, a knife and an insulating tape.

First of all, it is necessary to turn off the electricity in the room in which the switch will be replaced. To do this, in the storey electrical switchboard on the landing, you must turn off the circuit breaker (automatic) that powers this room or the whole apartment ...

The owners of small-sized Soviet-built apartments are hardly familiar with a similar problem. They are used to the fact that sockets are located on the walls. Well, in fact, where else? On the wall it is both accessible and safe - it will not flood with water and no one will kick or step with a foot.

But imagine some room in a luxurious country house with an area of ​​100 square meters or more. Let us suppress the impulses of, of course, white envy (and, perhaps, sincere hatred of luxury?) And imagine, let’s say ... a synthesizer.

Needless to say, the idle extension cord stretched to the instrument from an outlet in one of the walls will completely destroy all the pathos of the interior in such a situation? And how to power this damned synthesizer? The only solution that may come to mind is a wall mounted socket ...
