How to sockets and switches are indicated in the diagrams

Any right to repair or construction begins with the drawing, and on how well it is made, sometimes depends on everything. After the drawing is not only indicated where and how they will be laid supply lines, but also specified junction boxes, sockets and switches, and each of these elements has its conditional designation. In this article I will tell you how to designated outlets and switches are open, hidden location and more.

Regulations

In order to in each case power will not come up with a "bicycle" and charting could read absolutely any power engineering standards have been introduced, this material is based on GOST 21.210-2014. Taken as a basis of elementary geometric shapes, and by combining these or can receive the symbol of an element.

As depicted outlet

We begin our analysis with you the simplest rosettes outdoor installation: So, this is their symbol:

It was the outlet without grounding, and grounding contacts with flush-mounted, they are drawn as follows:

If you look at the circuit where the designated sockets in the bathroom, we can see that the inner part of them painted over. This means that these sockets have increased protection against moisture IP 44 or IP 55.

Computer sockets are designated as follows:

The only nuance is the factor that GOST is not clear how denote Weatherproof outlet for indoor installation.

Like with outlets all more or less clear, let's learn how designated switches.

Symbol switches

Image breakers also represent normalized and dash circle in the upper half of a hook at the end:

Flush mounting displayed as follows

All of the above presented switches are switches with IP 20-23 protection. Designation damp proof switches from normal is different only in that in the protected circle painted over.

Communicating switches are identified as follows:

combined units

Often, to save space and money are chosen so-called aligned units, is included in the composition of the add, for example, sockets and switches. Such hybrids have their own image, shared in the same, let's take a closer look.

Output

That is so designated and sockets and switches according to the current state standards. This information will allow you to intelligently read, as well as to make the wiring in your home or apartment.

Thanks for attention.
