Electrical circuits

Schémas de câblage manuels.

How to read electrical circuits — graphical, alphabetic, and numeric designations. Novices who try to assemble some kind of electronic circuits and devices on their own face the very first question in their new activity, how to read electrical circuits? The question is, in fact, a serious one, because before compiling a scheme, it must somehow be outlined on paper. Or find a ready-made version for implementation. That is, reading electrical circuits is the main task of any radio amateur or electrician.

What are the electrical circuits and what types they are

There are several different types of electrical circuits and any competent electrician must necessarily understand what they are for, how they differ from each other, what information they contain, what symbols are used on different circuits, how to read them correctly.

By type, all electrical circuits are divided into functional, structural, principal, connections and connections (installation) and location. There are special types of circuits, such as external electrical and pipe wiring diagrams, cabling diagrams. They carry out the installation and connection of wiring to electrical equipment and automation.

The most common type of electrical circuits - electrical schematic diagrams. They give a clear understanding of the operation of the installation, since all electrical circuits are shown on such diagrams. On the diagrams of electrical principle symbols are depicted all electric

According to the electrical concept, the correctness of the electrical connections is performed during installation and commissioning of electrical equipment. Such schemes are indispensable in operation and troubleshooting during repair. Although I once met at the factory old electricians working without schemes (often they simply did not exist), but this still does not mean anything. In this case, people were rescued simply by having experience when servicing the same machines for a long time.
