The electricity that comes to our apartments is strictly regulated by the legislation of state standards. In accordance with the requirements of the International Electrotechnical Commission for network 220, the deviation of the supply voltage is allowed within ± 10% of the nominal value or from 242 to 198 volts.

Even such a scatter of readings does not always favorably affect the operation of sensitive household electronic devices and ordinary, simple incandescent lamps used in lighting. Electricity distribution companies use transformer substations with power lines that supply electricity to each house and apartment. Often, when the lines are loaded, a situation is created when the maximum voltage value is already set on the transformer ...

Apartment owners are sometimes faced with the need to repair the doorbell or install its new model. To do this, they need to clearly know the electrical circuit of its connection and the principle of operation.

The calls by which the guest warns the owner of his arrival are divided into wired and wireless.

Such designs are the most common and known. Among them, first appeared electromechanical models, which began to be installed on the homes of noble people from the second half of the 18th century. They continue to work with small improvements to this day.

After the start of industrial development of semiconductor elements, doorbells began to be issued on an electronic circuit. They have the same type of bell ringing replaced by more diverse ...

Ventilation of the bathroom and toilet is an integral part of it. Ventilation provides an optimal microclimate in these rooms, both for a person and for objects and interior elements.

Firstly, ventilation significantly reduces the humidity in the room, which is especially true for the bathroom and toilet - rooms with high humidity. Humidity reduction prevents the formation of mold and damage to electrical appliances and interior elements due to increased humidity in the room. Secondly, ventilation eliminates undesirable odors and prevents the growth of bacteria.

Ventilation can be either natural or artificial. In the absence of the possibility of providing natural insulation of the bathroom and toilet, artificial ventilation is used ...

A cooker hood is an integral element of a kitchen interior. A range hood provides a comfortable stay for people in the room, clearing the air of unwanted odors and burning. If you need to connect a cooker hood, a lot of questions arise, one of which is how to connect a cooker hood to an electrical network.

The connection of the hood is carried out, as a rule, in a conventional power outlet. Therefore, it is recommended to provide a socket for connecting the hood when performing work on replacing the electrical wiring of the apartment. Consider the features of installing a socket for a kitchen hood.

The power consumption of the cooker hood is relatively small, so it is not practical to pull a separate wiring line from the distribution panel. The outlet in this case can be connected in a junction box. If during the installation of wiring in the kitchen ...

Summer residents and owners of suburban housing, in which the power supply is low, often face a problem that arises during the installation and operation of the electric hot water supply system at home.

Turning on a powerful submersible pump of an automatic pump station with a running water heater leads to an overload of the mains and trips of the circuit breaker located in the shield near the electricity meter.

The reasons for this are clear, since the starting current of the electric motor can exceed its operating current by 2 to 3 times. And if silt or sand gets on the impeller of the pump, then not only the starting current increases, but also the working current. When the inrush current occurs when other energy-intensive consumers are connected to the power grid, this is enough to trigger the machine. After all, for example, a storage water heater installed in private homes...

Many are faced with a situation where when turning on several powerful consumers in apartments, cottages, offices and country houses, the machine switches off when overloaded.

Until recently, a simple solution to this problem did not exist. It was required to buy additional electric power, which is very expensive, and often impossible. Or install a priority relay, which is associated with significant time costs for the device, for the alteration of the wiring, electrical panel and subsequent repair of the premises.

However, there are household appliances that solve a complex problem without extra costs. Network load optimizers, for example, OEL-820, is a new type of priority relay designed to effectively reduce the power consumed by energy-consuming household appliances, prevent overload and shut down the machine ...

One of the distinguishing features of household electrical networks of large country houses is the presence of a large number of powerful power consumers. In addition to the traditional electric stove, it can be various hot water boilers, ventilation and pump installations, and some in the common house economy may even find professional stationary machines or other industrial units operating on electricity.

Powerful receivers can be considered those devices whose current rating exceeds the limit for the most powerful 220 volt sockets. This limit is 16 amperes, which corresponds to approximately 3.5 kilowatts for a single-phase network. Not so little, if you look. Indeed, for example, quick-boiling kettles have an average power of only two kilowatts, and most other household appliances - even less. But the fact is that the socket can be used to connect, but not to turn on the device ...

This article is more of a fact-finding and recommendatory nature and, possibly, stopping someone from taking ill-considered actions, from wanting to independently connect a generator.

So, how to connect the generator? If you drive the phrase “How to connect the power station to your home” in Google, then you will get a link to the YouTube video, where the bearded uncle shows clearly what to do, in what order to connect, where to stick. Whether or not to follow his instructions for connecting the generator is strictly personal, but we would not recommend doing this, since this method is extremely dangerous for both the generator and others.

I will tell you one case from my own practice. In a nutshell about yourself, who I am and how I make money from bread))). I am engaged in the sale, installation and maintenance of generators. When selling mini-power plants, we usually offer customers ...
