Rules for the construction of electrical installations (PUE) are the main regulatory and technical document that guides designers when calculating electrical installations of all types and modifications.
In other words, PUE are rules that describe the principles of constructing electrical devices, as well as the basic requirements for power systems, electrical components, elements and communications.

In fact, the PUE is the Bible and the main reference book for any qualified electrician. If a master comes to you who does not know what the Electrical Installation Rules are, he is not an electrician. Hit him in the neck.
The rules described in the PUE apply to newly constructed or reconstructed electrical installations of direct and alternating current with voltage up to 750 (kV), including special electrical installations.
Currently, the PUE is in force on the territory of the Russian Federation in the form of separate sections and chapters of the 7th edition and existing sections and chapters of the 6th edition.
History of the creation of the Rules
PUE has existed for more than 65 years (the first edition was published back in 1949). Due to the constant development of technology, the emergence of new technologies, and increased requirements for electrical safety and reliability of electrical installations, these rules are continuously supplemented and revised.
For example, the fifth edition was published in separate sections from 1976 to 1982. PUE 6 was developed and put into effect by the USSR Ministry of Energy and Electrification on June 1, 1985, and most of it is still in effect to this day.
The outdated chapters of PUE 6 are gradually being replaced by the corresponding chapters of PUE 7, as they are developed taking into account the most modern GOSTs, SNiPs and recommendations of working groups. Thus, the 6th edition of the PUE is still valid, with the exception of some outdated chapters (see the list below).
In the period from 2000 to 2003, the following chapters of PUE 6 lost force (and accordingly chapters of PUE 7 came into force):
- July 1, 2000 - section 6 in its entirety, as well as chapters 7.1, 7.2;
- January 1, 2003 - chapters 1.1, 1.2, 1.7, 7.5, 7.6;
- September 1, 2003 - Chapter 1.8;
- October 1, 2003 - chapters 2.4, 2.5;
- November 1, 2003 - chapters 4.1, 4.2.

How does the PUE 7th edition differ from the PUE 6?
The published sections and chapters of PUE-7 tightened the electrical safety requirements, which began to practically comply with international standards and norms. Some concepts were also introduced, for example:
- TN-S grounding system;
- grounding system TN-C-S;
- TN-C grounding system;
- CT grounding system;
- IT grounding system;
- protective grounding has replaced the concept of grounding;
- etc.
I would like to note that PUE-7 still does not take into account the requirements for the protection of electrical installations from fires in accordance with GOST R 50571.17-2000, from overvoltages during ground faults in electrical installations above 1000 (V), from switching and lightning overvoltages and discharges in accordance with GOST R 50571.19-2000, GOST R 50571.18-2000 and GOST R 50571.20-2000. Thus, it is obvious that PUE 7 is not a complete publication, and will certainly be supplemented in the future.
Our website presents a generalized version of the PUE, consisting of the PUE 6th edition with all chapters from the 7th edition that have entered into force. Thus, this is the most complete and up-to-date version of the Electrical Installation Rules, taking into account all official changes and additions.
