For wiring of a hidden type, as a rule, it is necessary to install sockets of the corresponding type, that is, hidden. Very often there are external outlets in the apartment. Perhaps, when installing the wiring, the previous owner of the apartment or an electrician performing work to replace the wiring decided to save his time and installed an outdoor type socket. He greatly simplified the work, since he did not have to mount the box directly into the wall for mounting a hidden socket.

The external outlet does not fit into the interior design of the apartment, since its entire body is located outside the wall. At this stage, the landlord decides to fix this problem and install a hidden socket, that is, an internal one. How to replace an external outlet with an internal one? First, you need to prepare for the work ...

We encounter electrical outlets every day, so it is very important that they are convenient and reliable. A lot depends on the correct choice of the outlet. Firstly, it is an opportunity to fully satisfy their needs in the inclusion of electrical household appliances. In addition, its service life depends on the correct choice of the socket.

When a person does not know the basic rules that must be followed when choosing an outlet, he often faces the problem of frequent failure of outlets. Perhaps, in this case, the outlet simply does not correspond to the actual load parameters of the household appliances that are included in it. Therefore, you need to know how to choose a quality outlet. We will talk about how to do this correctly in this article. At the moment, the range of sockets is very large. In this case, your task is to choose a quality outlet ...

At times, it seems that enough has been said about the rules for installing and operating electrical wiring. But, oddly enough, the question "what is the wiring and how is it arranged?" still many may be confused.

If you believe GOST, then the wiring in the apartment is a combination of all conductors, as well as devices for fastening and fixing these conductors, together with installation products and protection devices.

That is, the input cable, socket conductors and wires of the lighting circuit are electrical wiring. Sockets, switches, most of the lamps are also electrical wiring. We include junction boxes, cable channels, switchboards and automatic machines there. These are, so to speak, “actors.” And the “plot” is a simple relationship and relationship of these elements. Wiring in the apartment begins with an input cable ...

With electricity you need to be on you !!! (time-tested wisdom).

Many probably heard that a real electrician is not one that is not afraid of electricity, but one that is able to avoid direct contact with electricity. According to statistics, from electric shock, most often die electricians with experience of ten years or more. It is at this age that a sense of danger is dulled. Some experienced electricians test the presence of electricity by touch, yes, it is by touch. But why risk your own life when there are devices showing the presence of voltage?

There are a lot of devices showing the presence of voltage - from the simplest voltage indicator on a gas discharge lamp (neonka) to devices showing not only the presence of voltage but also many other parameters. In this article we will consider indicators and voltage indicators ...

When repairing or replacing wiring, the question necessarily arises of the choice of protection devices - circuit breakers, RCDs and difavtomatov.

Circuit breakers protect the line from overload currents and short circuit currents. For example, you turned on an overly powerful heater or electric oven in a conventional outlet, the current in the line exceeds the value acceptable for it, the wire begins to heat up and, in order to prevent overheating and melting of the insulation, the circuit breaker trips and disconnects this line after some time. In the event of a short circuit in the line, the circuit breaker trips almost instantly, disconnecting the protected circuit.

Residual current devices (RCDs) are used to protect a person from electric shock when touching live parts and to prevent dangerous leakage of current if the insulation is damaged ...

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 can even find professional stationary machines or other industrial units that operate 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 ...

The reason for writing the article was my viewing of several projects for the power supply of private houses. Designers are highly qualified specialists (he worked as a designer for 17 years), so I think that this is just a misunderstanding, which should be IMMEDIATELY corrected.

Now essentially the problem. In connection with the new requirements, the connection of private residential buildings should be done through the metering panel, which is installed outside the house. In all projects, this was done according to the scheme shown in the figure.

The analysis of this scheme does not withstand any criticism from the point of view of electrical safety of the residents of such a house. In case of malfunctions No. 1 and No. 3 (no contact) and malfunction No. 2 (PE wire break), the power supply to the apartment building will not be interrupted, and the protection circuits along the PE conductors will not work ...

Power supply systems using autonomous sources are becoming increasingly popular among owners of country houses. It is understandable: the cost of electricity supplied centrally is growing steadily year by year. In addition, the quality of this electricity often leaves much to be desired, and constant power outages in some regions generally preclude the normal use of the benefits of civilization. Then the idea will inevitably arise of having your own power source and not depend on anyone.

There are several ways to provide autonomous power generation at home, but, unfortunately, all of them are not without their drawbacks. Consider the main ones in more detail. Gasoline or diesel generator set. The advantage of these installations is true autonomy ...
