Planning the placement of electrical wiring in a room is a serious task, the accuracy and correctness of which depends on the quality of its subsequent installation and the level of safety of people in this area. In order for the wiring to be placed efficiently and competently, it is required to draw up a detailed plan in advance.
It is a drawing made in accordance with the selected scale, in accordance with the layout of the housing, reflecting the location of all electrical wiring nodes and its main elements, such as distribution groups and a single-line schematic diagram. Only after the drawing has been drawn up can we talk about connecting an electrician.
However, it is important not only to have such a drawing at your disposal, you also need to be able to read it. Each person dealing with work involving the need for electrical installation must navigate in the conventional images on the diagram, denoting various elements of electrical equipment. They look like certain symbols and they are contained in almost every electrical circuit.
But today we will not talk about how to draw a plan diagram, but about what is displayed on it. I will say straight away complex elements such as resistors, automatic machines, circuit breakers, switches, relays, motors, etc. we will not consider, but consider only those elements that are encountered by any person every day, i.e. designation of sockets and switches in the drawings. I think it will be interesting for everyone.
What documents are used to regulate the designation
GOSTs, developed back in Soviet times, clearly define the correspondence of the elements of the electrical circuit to certain established graphic symbols on the diagram and in the design documentation. This is necessary to maintain generally accepted records of electrical system design information.
The role of graphic symbols is performed by elementary geometric shapes: squares, circles, rectangles, points and lines. In various standard combinations, these elements reflect all the components of electrical appliances, machines and mechanisms used in modern electrical engineering, as well as the principles of their control.
Often a natural question arises about the normative document governing all of the above principles. Methods for constructing conventional graphic images of electrical wiring and equipment on the corresponding diagrams is determined by GOST 21.614-88 "Conventional graphic images of electrical equipment and wiring on plans." From it you can learn how sockets and switches are indicated on electrical diagrams.
Designation of sockets in the diagram
Regulatory technical documentation gives a specific designation of the outlet on electrical diagrams. Its general schematic view is a semicircle, from the convex part of which a line extends upward, its appearance determines the type of outlet. One feature is a two-pole socket, two are a double two-pole, three fan-shaped is a three-pole socket.
Such sockets are characterized by a degree of protection in the range IP20 - IP23. The presence of grounding is indicated on the diagrams by a flat line parallel to the center of half of the circle, which distinguishes the designations of all sockets of open installations.
In the event that the installation is hidden, the schematic images of the outlets are changed by adding another feature in the central part of the semicircle. It has a direction from the center to the line indicating the number of poles of the socket.
At the same time, the sockets themselves are embedded in the wall, the level of their protection against moisture and dust is in the range given above (IP20 - IP23). The wall does not become dangerous from this, since all parts that conduct current are reliably hidden in it.
In some diagrams, the outlet designations look like a black semicircle. These are moisture resistant sockets, the degree of protection of the shell is IP 44 - IP55. Their external installation on the surfaces of buildings facing the street is allowed. In residential areas, such outlets are installed in damp and damp areas, such as bathrooms and showers.
Designation of switches on electrical diagrams
All types of switches are schematic in the form of a circle with a line at the top. A circle with a dash containing a hook at the end stands for one-button light switch for on-site lighting(degree of protection IP20 - IP23). Two hooks at the end of the line represent a two-button switch, three - a three-button switch.
If a perpendicular line is placed above the dash on the schematic designation of the circuit breaker, we are talking about flush-mounted switch(degree of protection IP20 - IP23). Line one - single-pole switch, two - two-pole, three - three-pole.
A black circle denotes a moisture-proof open-circuit switch (degree of protection IP44 - IP55).
The circle crossed by a line with dashes at the ends is used to represent two-position (IP20 - IP23) pass-through switches (switches) on electrical diagrams. The image of a single-pole switch resembles a mirror image of two conventional ones. Waterproof switches (IP44 - IP55) are marked with a filled circle in the diagrams.
As indicated by the switch box with socket
To save space and for the purpose of layout, an outlet with a switch or several sockets and a switch are installed in a common unit. Probably, many such blocks have met. Such an arrangement of switching devices is very convenient, since it is located in one place, besides, when installing electrical wiring, you can save on strobes (wires to the switch and sockets are laid in one strobe).
In general, the layout of the blocks can be any and everything, as they say, depends on your imagination. You can install a switch box with socket, multiple switches, or multiple outlets. In this article, I simply have no right not to consider such blocks.
So, the first one is a block socket switch. Designation for flush-mounted installation.
The second, more complex unit, consists of a one-button switch, a two-button switch, and an earthed socket.
The last designation of sockets and switches in electrical diagrams is shown as a block of two switches and a socket.
For clarity, only one small example is presented; you can assemble (draw) any combination. Once again, it all depends on your imagination).

Plywood is mounted on a rigid frame, which is installed directly on a rigid base, for example, made of bricks, reinforced concrete, etc. all surfaces accessible to touch. The test device is calibrated for the impact energy of the pendulum shown in Figures 17-20 of GOST 30988.1. On each test plane, three hits are applied to each of the three weakest points (no more than nine hits). The impact element of the pendulum must have the energy specified in Table 103. . Table 103
Care must be taken to ensure that the results of one series of three blows do not affect the results of subsequent series of blows. If there is any doubt that the cause of a defect in the socket is a previous series of blows, then this defect is neglected and the series of three blows that caused the defects are applied in the same place on a new sample that must withstand this test. After testing, there should be no damage to the samples that violate the requirements of this standard. Live parts should not be exposed. The device consists of three main parts: a body, an impactor and a trigger cone with a spring. The body consists of a striker guide casing, a trigger and other parts rigidly attached to it. The mass of the enclosure shall be (1250 ± 10) g. Note - Do not take into account: - damaged edges, small dents that do not reduce creepage distances or air gaps below the values specified in 26.1; - small chips that do not affect protection against shock electric shock, or water ingress; - cracks not visible to the naked eye and superficial cracks in fiber castings and similar parts; - cracks or holes in the outer surface of any part of the socket if the socket complies with the requirements of this standard even without this part. the element consists of a hammer head, a rod and a cocking button. The mass of the striking element should be (250 ± 1) g. The hammer head has a semicircular shape with a radius of 10 mm and is made of polyamide with a hardness of 100 HRC; it must be attached to the hammer rod so that the distance between its apex and the plane passing through the end of the cone immediately before the release of the impactor is 20 mm The mass of the cone is 60 g, the spring of the cone just before the release of the impactor must create a force of 20 N The spring of the striker is adjusted so that the product of the compression value in millimeters and the force in newtons is 1000 and its compression length is about 25 mm.
