PUE 7th edition PDF

Full title and description

PUE 7th edition — Правила устройства электроустановок (Rules for the Arrangement of Electrical Installations), 7-е издание. National technical code used in the Russian Federation that collects mandatory and recommended rules for the design, erection, protection, testing and safe operation of electrical installations (covering voltages up to 750 kV).

Abstract

The 7th edition of the PUE consolidates current requirements for electrical installations in buildings, industrial sites and special installations, addressing wiring and cable systems, protective devices and automation, earthing and equipotential bonding, lighting, lightning protection, testing and commissioning. It is used as the principal reference for project designers, installation contractors and operating organisations working with electrical systems in Russia and in jurisdictions that adopt or reference Russian electrical practice.

General information

• Status: Active / in force (current national technical rules — ПУЭ, 7th edition).
• Publication date: Approved 6 October 1999; main introduction from 1 July 2000 with subsequent chapter updates introduced between 2000–2004 (specific chapters updated at later dates).
• Publisher: Developed and prepared by VNIIPI/industry working groups and approved by the Ministry of Fuel and Energy of the Russian Federation; commercial printings issued by national technical publishers (editions and reprints vary).
• ICS / categories: Electrical engineering; typically classified under ICS 29.020 (electrical engineering — installations and related safety/installation practice).
• Edition / version: 7th edition (ПУЭ — Издание 7). Several chapters were revised and introduced on staggered dates (1999–2004) and later editorial updates/reprints have been published.
• Number of pages: Varies by printing. Consolidated 2‑volume editions are commonly listed at about 550–560 pages (some translated/extract versions and commercial single‑volume prints list smaller page counts such as ~222 pages for selected extracts).

Scope

PUE 7th edition applies to newly constructed and reconstructed electrical installations of both alternating and direct current up to and including 750 kV, including special installations covered in the document. It sets requirements for selection of conductors and protective devices, cable routing and raceways, earthing and lightning protection, lighting systems (internal, external and advertising illumination), protection and automation, and rules for testing, operation and maintenance of electrical installations.

Key topics and requirements

• General rules for electrical safety, documentation and acceptance testing.
• Selection and sizing of conductors and protective equipment (short‑circuit, overload and selective coordination).
• Cable and busway routing, raceways, supports and fire‑safety measures.
• Earthing (grounding) systems, equipotential bonding and protective measures against electric shock.
• Lighting installations (indoor, street and special-purpose), including requirements for luminaires and circuit protections.
• Protection and automation: relay protection, overload, short‑circuit protection and coordination.
• Rules for special installations and equipment (industrial, transport, medical, explosive atmospheres, etc.).
• Testing, commissioning, maintenance, inspection intervals and record keeping.

Typical use and users

Primary users include electrical designers and engineers, installation and commissioning contractors, operating and maintenance personnel of electrical networks and facilities, inspectors and regulatory bodies, utilities and industrial plant engineers. The PUE is used for project design rules, construction oversight, technical audits and as a compliance reference for safety and acceptance testing in Russia.

Related standards

PUE is used alongside other national and international standards and codes: IEC/ISO/EN publications on electrical installations (for example IEC/EN 60364 series), national wiring rules and GOST/R regulations (including GOST R 50571 series which align with IEC 60364 in many areas), and industry‑specific standards for protection, switchgear and lightning protection. PUE often functions as the authoritative national code within Russia while cross‑referencing IEC and GOST documents for equipment and detailed test procedures.

FAQ

Q: What is this standard?

A: PUE (Правила устройства электроустановок) — the national rules for arrangement of electrical installations in the Russian Federation; the 7th edition is the consolidated edition of those rules currently used as the principal technical reference.

Q: What does it cover?

A: It covers design, selection of conductors and protective devices, cable and raceway systems, earthing/ bonding, lightning protection, lighting installations, protection and automation, testing, commissioning and safe operation of electrical installations up to 750 kV and many special‑purpose installations.

Q: Who typically uses it?

A: Electrical designers, project engineers, installation and commissioning teams, maintenance and operating personnel, inspection authorities, utility engineers and organisations responsible for electrical safety and compliance in Russia and for projects that reference Russian practice.

Q: Is it current or superseded?

A: The 7th edition is an active/operative set of rules; different chapters were introduced or revised at specific dates (approved 6 Oct 1999; main introduction from 1 Jul 2000, with subsequent chapter updates through 2002–2004). Users should ensure they consult the latest editorial reprints, amendments and any successive updates or national regulations that amend particular chapters.

Q: Is it part of a series?

A: PUE is the national wiring/installation code (historically issued in multiple editions — 6th, 7th, etc.) and is used together with related GOST/R standards and the IEC/EN/ISO corpus (for equipment, testing and detailed technical specifications). Some chapters of the 7th edition replaced or updated content from earlier editions.

Q: What are the key keywords?

A: Electrical installations; wiring rules; earthing/grounding; equipotential bonding; protection and automation; cable routing; lighting; lightning protection; commissioning; electrical safety; Russia; PUE 7th edition.
