A situation is quite common when the established number of sockets in a particular room of the apartment is not enough to simultaneously include all the necessary household appliances in the network. In this regard, one or several electrical appliances have to be connected to the network one at a time, which is not very convenient and ordinary household chores are delayed in time. How to solve this problem?

If the wiring is quite old and is in unsatisfactory technical condition, then it is necessary to replace it, mounting a new wiring already with the number of outlets necessary for convenient operation. But this option, as a rule, is combined with the overhaul of an apartment or a private house, since with a complete replacement of the wiring it will be necessary to violate the integrity of the finish coating of the walls and ceiling throughout the house ...

Choosing a socket or switch can be a daunting task, because now in the assortment of construction stores are thousands of models that vary in color, modification, material. Here we show a photo of a large number of different models of sockets and switches in the interior of the premises.

Switches and sockets for the home are of various types and types. Most often, switches and sockets are made of special plastic, which has increased strength, does not fade in the sun and is not afraid of moisture. There are also wooden, stone, aluminum, steel, glass options. The frame and the button of the wall switch itself can be made of different materials. The frame can be matte and glossy, smooth and rough, even removable. If your apartment is presented in one single style, you can apply a set of sockets and switches that are offered by manufacturing companies ...

To adjust the brightness of the glow of the lamps, special electronic devices are used - dimmers. And if earlier this concerned only incandescent lamps, then with the advent of LED lamps on the market, there was a need to regulate them. In general, the dimmer function is to lower the average current through the lamp to the desired level, and thus reduce the intensity of the light emitted by it.

So, with incandescent lamps, triac and thyristor dimmers are traditionally used, which adjust the power supply to the lamp by cutting off part of the phase of the mains voltage. Since incandescent lamps are quite ingenious devices, then dimmers for them are quite simple in design. With LED lamps, the situation is more complicated.

Ordinary LED lamps sometimes contain in their design, in addition to LEDs, also a simple pulse converter circuit, which is designed to interact with an ordinary ...

This review will focus on smart GSM sockets. GSM sockets are devices for expanding home automation. At the moment, the range of such outlets is quite wide, and it is not surprising that they have already gained some popularity among discerning consumers.

For example, consider three models from three manufacturers, so that anyone who hears about these devices for the first time can form a clear idea of ​​what kind of devices they are, how they work, and what opportunities they open up. Each of the models presented in the review is unique in its own way and has its own characteristics. This model is an improved version of the device from the Russian company Senseit. It supports management from an application for iOS or Android, and there is no longer any need to send SMS commandsas it was in the first version of the outlet ...

Industrial and residential wiring is carried out in one of two ways of laying: hidden inside wall structures and outdoor installation. Under each of these types, junction boxes, sockets and switches are also available, which are also called electrical points or network connection nodes.

During their installation, many home masters focus on the design of the room and ease of use. However, it is worth considering electrical requirements for them, such as: reliable contact joints that ensure high-quality transmission of electricity with minimal voltage losses, durable electrical insulation of current-carrying conductors and structural elements that are under the network potential, operation safety, including ease of operation, access restrictions, fire protection. In the old Soviet-built houses inside the walls created emptiness channels and outlet openings ...

The way to connect electrical appliances to the power supply using a plug and socket exists for a very long time and works reliably. In most cases, such compounds have been functioning properly for decades, without requiring special repairs and maintenance.

However, each landlord can cite facts from his life when malfunctions occurred in these simple-looking devices. But often the causes of their occurrence were not analyzed and ... repeated, oddly enough.

Malfunctions of sockets by types of destruction arise due to: mechanical breakdowns and excess electrical loads. In the first case, due to the application of excessive force, the threads of the connecting parts are torn off or the insulating bodies and covers are broken. Insufficient fastening force of the parts leads to the subsequent pulling out of the socket under voltage from the junction box or burning ...

When repairing electrical wiring, it is always necessary to have access to the ends of the connecting cables and the contacts of sockets, switches. In modern buildings, a hidden method of installing communications is often used, when all wires are hidden inside the walls for security and design purposes.

To the veins of the cable ends can be reached only at the entrance of the lamp, switch, socket and electrical distribution box. For the convenience of servicing such electrical equipment, certain rules must be taken into account: cables are laid along certain routes provided by the project, in the places where sockets and switches are installed inside the wall, recesses are made to accommodate the corresponding equipment, installation boxes are mounted inside the recesses into which the switches and sockets are mounted. The most favorable time for such work ...

For home lighting, switches of various designs are used. All of them relate to switching devices with two positions of the working body, which determine the boundary states of opening the electric circuit and applying voltage to the lamp.

Lighting control in most cases is performed manually. Housing switches are designed to work in home wiring at rated network parameters and are not designed to trip excess currents and short circuits.

This protective function is performed by the automatic switches of the apartment panel, which are equipped with current releases, cut-off mechanisms and arc extinction systems.Any model of a light switch is created for certain technical tasks: operating current, mains voltage, degree of dust and moisture resistance, installation method...
