The article provides simple rules that must be observed when using electricity in everyday life.

Electricity has long and firmly entered our lives. Modern man cannot even imagine his life without electric energy. The discovery of electricity brought a lot of amenities and useful appliances to our daily lives. Electricity has penetrated into all spheres of human life.

Behind the seeming simplicity and harmlessness of electrical energy is a great threat to human life and health if he forgets about the basic precautions and safe operation of electrical networks and household appliances ...

Classification of grounding systems of electrical installations and modernization of apartment wiring. Application Experience.

For proper repair or modernization of wiring, you need to know exactly which grounding system is applied at the facility. Your safety depends on this, in addition, it is important when drawing up a reconstruction project. In some cases, for example, a three-core cable is used, and in others four and five-core cable.

The International Electrotechnical Commission and, with its submission, the 7th edition of the PUE (Electrical Installation Rules) distinguish 3 grounding systems and several of their subsystems. 1. TN system (subsystems TN-C, TN-S, TN-C-S); 2. TT system; 3. IT system ...

Practice gaskets electrical wiring for wooden buildings with wet rooms.

Increasingly, in order to equip everyday life in the country, people build not only residential buildings, but also farm buildings, saunas and gazebos. In the 21st century, no one can do without electricity, but the wiring in a wooden house and bathhouse has its own characteristics compared to a brick building.

In the bathhouse, if it is a separate building, it is advisable to extend your line from the main switchboard, which is usually located in the house. This line should be protected by a separate machine. There are two ways to run the power cable into the bathhouse ...

ATS - Automatic activation of the backup generator. We continue the series of articles on the topic of autonomous power supply of a private house.

In previous articles, we examined in sufficient detail various types of autonomous sources of electricity, namely - UPS (uninterruptible power supplies on rechargeable batteries) and GU-generator sets.

There was also an article on how to combine two devices - a mini-power plant and a UPS in order to achieve maximum results during operation. In this article we will consider the device through which the mini-power plant is controlled. The name of this device is ABP-automatic backup power on. Almost all mini-power plants, and no matter how quiet they work, give out quite a lot of unpleasant decibels. For example, a relatively quiet mini-power plant ...

We continue the series of articles on the topic of autonomous power supply for a private house.

In previous articles, we have already considered several types of autonomous sources of electricity, namely: UPS uninterruptible power supplies, where batteries are the source of electricity, and generator sets for diesel fuel, gasoline or gas are the second source of energy.

The advantages and disadvantages of each of the devices we examined, as far as possible in words, is quite extensive, in the same article we will try to figure out how to combine both of these devices, to use the full potential of both the generator set and the uninterruptible power supply to the maximum. For a more complete picture of the upcoming event, I would like to note a relatively high cost ...

Classification and practical experience of electrical wiring protection systems

Automatic machines or circuit breakers, this is what replaced the usual traffic jams, i.e. fuses in a ceramic case, where a blown wire was a protection against overcurrent.

Unlike plugs, automatic reusable devices and protection functions are separate. Firstly, overcurrent protection, and secondly, overload protection, i.e. the mechanism of the machine breaks the load circuit with a slight excess of the operating current of the machine. In accordance with these functions, the machine contains two types of circuit breakers. Magnetic fast-acting circuit breaker for short-circuit protection ...

The main types of lighting switches: control switches, illuminated switches, dimmers, anti-vandal switches. The main advantages of using various models of switches.

Manufacturers of electrical products, despite the seeming limited functionality, offer a modern consumer a variety of models for the capabilities and structure of lighting switches. It is enough to pay attention to single-key, two-key or three-key options. If you look at the western market, then there we will not see a model with more than three keys.

If necessary, Europeans combine several devices of the same type with one frame. In the eastern market, the situation is different ...

Modern technology and practice of manufacturing grounding systems

The grounding device is an important element of the system for protecting people from electric shock. Therefore, it is necessary to pay due attention to the issue of manufacturing grounding at the project stage.

A grounding device can be manufactured in many ways, the criterion for choosing a specific one is to provide the desired resistance (8 Ohms for 220V, 4 Ohms for 380V) and stability of parameters throughout the entire operation period.

The instability of the grounding properties is caused by a change in the resistance of the soil, when the external temperature (winter / summer) changes and the corrosion of the grounding elements ...
