There are several different types of electrical switchboards, each of which has its own design features and scope. In this article, we give a brief description and purpose of the existing types of shields.

According to the installation method, switchboards are of three types: overhead, built-in and floor. Overhead shields are mounted directly on a wall, support or other building construction. The main distinguishing feature of the shields of this type is that its entire body is located outside. Built-in shields are mounted in a pre-prepared recess in the wall. Thus, only the lid is visible from the outside, and the entire body is recessed into the wall. The floor guard is installed directly on the floor surface or mounted on a special stand. As for the installation location, in this case ...

When undertaking the ceiling decoration at home or in the office, we often opt for a stretch ceiling made of PVC. And here it is important to decide in advance which fixtures to install and how many will be required. In this sense, LED spotlights are today one of the most economical solutions due to their high light output and durability.

The first thing, even before installing the stretch ceiling, lay electrical wiring for future lighting. This is done according to a pre-designed scheme: the number of bulbs, their location, rated power. However, this process has its own peculiarities, subtleties and nuances, which will be discussed later. The number of LED fixtures is selected based on the area and purpose of the room in order to obtain sufficient illumination, and taking into account the restrictions on the heating temperature of PVC - it should not exceed 60 ° C ...

Electric networks are an object of increased danger and their condition must be constantly carefully monitored. Often, a fire is caused by worn or inappropriate power consumption. To avoid this, it is necessary to regularly diagnose its condition and, if necessary, perform its full or partial replacement.

Wiring in an apartment and a house - which is better? The cable with which material lived better - aluminum or copper? When installing electrical wiring in the apartment, conductors (wires and cables) made of aluminum and copper are suitable. But is it really important what they are made of? Is it worth changing the aluminum wiring to copper? Maybe you can leave it as it is and not touch anything? In this article, we consider the following issues: the service life of aluminum and copper electrical wiring, for which it is necessary to change the aluminum wiring to copper and in what cases ...

Every day we use sockets to connect electrical appliances to a 220 volt network, while we don’t think about the outlet itself. Meanwhile, sockets are different. And in the framework of this article, we will consider how the outlet is arranged, and talk about what kind of outlets generally exist.

In everyday life today, sockets of the European standard are installed everywhere, having a tight fit of the plug, often a recessed seat. The plug holes are, of course, round, the difference between the Euro-standard socket and the old Soviet ones - the socket accepts plugs with thicker pins. Any modern outlet consists of: a base with fasteners, current-carrying parts and a face plate.The base of the outlet with mounting tabs or ears has current-carrying parts on it, and the front plate (panel) is also attached to it. Base material - plastic or ceramic. Ceramic substrates are better tolerated ...

After people began to use the energy of electricity to perform useful work, they immediately ran into questions of getting electrical injuries from burns that occur when exposed to electric current. For example, back in 1753, on July 26, professor of the St. Petersburg Academy of Sciences Georg Wilhelm Richter, while conducting experiments with atmospheric electricity, died from contact with ball lightning. After this incident, such studies were immediately suspended, and the causes of what happened began to be studied.

Almost all the leaders did this after each accident to study the causes of its occurrence. As a result of the collection of accident statistics and their detailed analysis, recommendations were developed on the safe behavior of people in order to maintain their health and ensure the normal operation of the equipment. Over time, they were legally issued the requirements of the rules and regulations ...

Electrical assistants have firmly and permanently entered our lives. They facilitate the performance of routine homework, save a person from monotonous physical labor. Therefore, manufacturers of household appliances are constantly improving their products, providing them with new features and improved capabilities for operating conditions with increased safety. However, in real life, for some reason, it turns out that a new serviceable washing or dishwasher is shocking and requires grounding. Let's try to figure out why this is happening and how to do the right thing in this situation.

Modern production is designed to produce household electrical products designed to work in three-phase wiring. It is connected via the TN-S grounding system using a separate PE conductor providing reliable electrical connection ...

In the operation of home wiring, the most important issue is the safety of the operation of household electrical appliances. Grounding of electrical wiring is the main way to minimize the impact of electric current on a person in the event of a life-threatening potential on the metal case of household electrical appliances. The problem of the lack of grounding in the apartment or in the house is quite common due to the power supply from outdated TN-C configuration networks in which the grounding of home electrical wiring is not provided.

To solve the problem, proceed as follows - ground the electrical wiring through the alteration of the TN-C system to TN-C-S. As a result, improper grounding of the wiring makes the operation of the wiring even more dangerous than in the absence of grounding per se. In this article, we consider the danger of self-grounding ...

Power surges are one of the most common problems faced by residents of apartments or private houses during the operation of electrical appliances. By the concept of voltage surges we mean, as a rule, short-term or impulse changes in the voltage value, both in the direction of increase and decrease.

Depending on the cause, the voltage drops can have a different frequency, amplitude and total duration.In any case, this phenomenon is abnormal and the question arises as to how dangerous it is for household electrical appliances and home wiring and how to eliminate the possible consequences of this phenomenon. In this article, we will consider in detail the question of why voltage surges occur and how to protect oneself from them. First of all, it should be noted that each household appliance is designed for normal operation, provided that it is powered ...
