All electrical work that are held in the apartment should be carried out on the basis of electrical installation schemes. Not only wiring, but electrical equipment has its own schemes. Here we gave to your attention the designation of the socket on the electrical circuit.
Designation of sockets and switches should know every person
The conventions often often include images that are generally understood. The designation of sockets allows you to significantly facilitate reading any drawing.
Standards that determine the conditional designation of sockets
To date, the conditional designations in the schemes standardizes the new GOST 21.614.88. This standard came out quite recently and completely replaced the current GOST. Now each designation of sockets in the diagram should coincide with this document. When applied to the scheme of other devices, you need to be guided by GOST 2.721.74. This document places general application designations.
What does the scheme look like where the outlets and switches in the house are displayed
In the event that you need to read the scheme of introductory and distribution devices, you must read GOST 2.721.74. Phase and zero in the outlet can also have its own designations in the diagram.
Designation sockets in schemes
Here is the general designation of sockets that can be found in the construction drawings:
This is how an ordinary socket is denoted.
Electrically sockets are today one of the main elements of wiring in the house. All products that are produced by manufacturers may differ:
- According to the degree of protection.
- By the installation method.
- By number of poles.
Remember! It is for this reason that the designation of sockets in drawings may be different.
Designation for outdoor and open installation
In the image below we submitted to your attention a socket:- Dual single-pole with grounding.
- Dual single-pole without grounding contact.
- Silent single-pole with protective contact.
- Power three-pole with protective contact.

Designations of complex sockets in the schemes
Designation of sockets for hidden and internal installation
In the image below we submitted to your attention the following outlets:
- single single-pole with grounding;
- dual one-pole;
- Three-pole;
- Single single-pole without protective contact.
Designations of sockets for internal and hidden installation in the diagram
Conventions of moisture-proof devices
The designation in the drawings of the moisture sockets can be as follows:In the bathroom, use outlets with moisture protection
- Single single pole devices.
- Single single-pole devices with grounding.
Legend block sockets and switch
In the picture below, we submitted to you:
Color switch and socket.
Socket and Switch Designation (Couples)
Designations of switches in diagrams
All switches in diagrams are displayed as follows:
In the switches, the designation is simple, but it should be remembered
Designations of single-color and two-vector switches
In the image you can see the following switches:Single-pole two-block and color switches received a rather complicated designation
- external;
- overhead;
- embeddable;
- internal.
Here is the generally accepted table that contains the conventions of sockets, switches and switches. Here are all kinds of outlets that you can meet.
To date, the release of these devices is quite diverse. That is why new devices appear, much faster than their designations. If in this image you will find unknown badges, then just look at the footnotes.
Video on the topic
We also recommend to see a few videos that will open for you a complete understanding of how the designation of sockets and switches in the diagrams used during the electromotion of any complexity looks.
Looking at this video, you will understand how to read the designations of sockets and switches:
In this video, it is described in detail how to draw sockets and switches on electrical circuits.
