We use electricity every day. We don’t even notice how many times a day we press the light switch or insert the plug into a power outlet. Sockets and switches belong to wiring accessories and how long they last will depend on their quality. Buying cheap options, we do not think about whether we will save or spend more on their periodic replacement, so you need to consider options from well-known manufacturers. In this article we will talk about the popular manufacturer of sockets and switches Legrand.

Legrand company was founded in 1866, was engaged in the production of table porcelain. But with the advent of electricity and the beginning of the electrification of cities, porcelain began to be regarded not only as a material for saucers and cups, but also as an insulator. Already in 1949, the company began to thoroughly engage in the production of wiring products. By 1966, the first international representation of Legrand in Belgium was opened. Now on the market Legrand is represented by a number of brands ...

Fluorescent lamps cannot work directly from a 220V network. To ignite them, you need to create a high voltage pulse, and before that heat their spirals. To do this, use ballasts. They are of two types - electromagnetic and electronic. In this article we will consider electronic ballasts for fluorescent lamps, what is who and how they work.

Fluorescent lamp is this gas-discharge light source. It consists of a tube-shaped flask filled with mercury vapor. At the edges of the flask are spirals. Accordingly, on each edge of the flask is a pair of contacts - these are the conclusions of the spiral. The operation of such a lamp is based on the luminescence of gases when an electric current flows through it. But the current just between the two metal spirals (electrodes) just does not flow. For this, a discharge must occur between them, such a discharge is called smoldering ...

The heating cable has found many uses, it is used to heat the floor, the greenhouse, to prevent freezing of pipes and to defrost them. It is also convenient to use it for heating the roof, so that the snow will not linger on it, and you will avoid the descent of snow and ice blocks from the roof. Usually it is sold a fixed length for a specific situation, but still, in case of damage or the need to increase the length - you have to connect.

In principle, the process consists in simple twisting or sleeving of conductive conductors, but there are some nuances that depend on the type of cable. There are two types of cables: resistive and self-regulating. In resistive electricity is converted into heat due to the high resistance of conductive wires. They are divided into two subspecies - ordinary single-core and two-core resistive cables and zonal. Please note when buying a single-core cable that both ends of it ...

Smart home is a system that makes the equipment work for you and simplifies life. In order to make your home smart, you either need to radically redo the entire wiring and introduce microprocessor or even microcomputer control systems ... Or go softer, different way, gradually equipping it with smart things. The simplest thing you can do is automate the lighting. This article will discuss how smart lamps help in this and what it is.

What is a smart lamp? The concept of "smart" or "smart" in our time is glued to almost all technology. Progress has come to seemingly such a simple and mundane thing as a light bulb.What is called a smart lamp? There are two possible answers: A lamp or a full-fledged lamp with additional functions, such as automatic switching on by popping, human presence, in the dark and when other sensors are triggered. Lighting device with a set of sensors and a microcontroller system ...

LED strip is a multifunctional light source, thanks to its low voltage DC power supply and low power consumption. On the modern market, there are types of ribbons from low-power, for use for decorative purposes, to bright ones that are suitable as a light source. Also interesting are multi-color RGB models. In this article we will look at where you can use LED strips.

LED strips are powered with DC voltage of 12V. This means that you definitely need to buy a power supply for this voltage of the corresponding power, then we will give a table of consumption of different tapes. In fact, the luminous flux depends on the LEDs used.Next, determine how you will connect the power and connect the segments of the tape. If you are going to solder, then you need a 25-40W soldering iron, rosin or another flux, for example, LTI-120, and solder, for example POS-60 ...

Everyone knows the circuit breakers. In the people they are called simply "automatic". And everyone in the house or apartment has at least one, or even two such devices. Automatic machines protect wiring from emergency situations and prevent their development. Manufacturers print a whole series of text on their case, but not everyone understands what it says. This article will help you decipher the label of circuit breakers.

In terms of the appearance of the majority, it is impossible to determine what current it is rated for, the only thing you can guess from its size is it passes a large or small current and how many phases (poles) it is designed for. How to determine the characteristics of the machine? You just need to read the markings.Marking a series of machines allows you to find complete documentation with all the technical characteristics and features of the model. It is indicated either under the logo of the manufacturer ...

Electric stoves and ovens are often used in the home kitchen. In this case, the choice of the type of stove does not depend on the presence of gas in the house. However, these are powerful electrical appliances and the recommendations for their connection must be followed. It should be noted that the wiring must be designed for the power of these consumers in order to avoid emergency situations. In this article we will talk about the intricacies of connecting to a network of kitchen electrical equipment.

If you have both an electric oven and a hob installed, the first thing you need to do is decide on the models and recommendations of the manufacturers. In some cases, the stove and oven are connected independently of each other, but if these are models from the kit of the same manufacturer, you need to look in the instructions, maybe they should be interconnected. Connecting the cord to the electric stove, depending on the manufacturer, the cord can be removable or non-removable ...

In production and in everyday life, automation is actively used. For this, actuators of various types are used, hydraulic, pneumatic and electric. Such devices include, disable, change the mode of operation of mechanisms, systems and devices. In this article we will look at some electromagnetic actuators.

To propel various mechanisms using electric motors and electromagnetic actuators.For example, electric motors are used for automatic or semi-automatic control of valves, the so-called shutoff valves on pipelines, like gas, pneumatic, water supply and other. The principle of operation of an electromagnetic actuator is to perform a magnetic field to move the core associated with actuators ...
