GOST 30331.1-2013 PDF

Full title and description

GOST 30331.1-2013 — "Low-voltage electrical installations. Part 1. Fundamental principles, assessment of general characteristics, definitions". This national (GOST) implementation captures the basic principles, terminology and general requirements for the design, erection and verification of low-voltage electrical installations (installations supplied at nominal voltages up to 1 000 V a.c. or 1 500 V d.c.). It is based on IEC 60364‑1 (fifth edition, 2005).

Abstract

The standard establishes fundamental rules for safe design, installation and testing of low-voltage electrical installations used in residential, commercial, public, industrial and other premises. It defines key terms, describes how to assess general characteristics of installations and sets out the objectives of protection (against electric shock, thermal effects, overcurrent and overvoltages) and principles for selecting and applying electrical equipment. GOST 30331.1-2013 harmonises national practice with IEC 60364-1:2005 and serves as the foundational Part 1 for the GOST 30331 series covering low-voltage installations.

Scope

GOST 30331.1-2013 applies to the design, erection and verification of low-voltage electrical installations in a wide range of premises and situations (residential, commercial, public, industrial, agricultural, prefabricated buildings, construction sites, marinas, temporary installations, photovoltaic systems, low-voltage generating sets, etc.). It covers installations supplied at nominal voltages up to and including 1 000 V a.c. and 1 500 V d.c., and addresses the assessment of general characteristics, fundamental safety objectives, and the definitions needed for the remainder of the GOST 30331 series.

Key topics and requirements

• Fundamental safety objectives and principles for electrical installations (protection of persons, livestock and property).
• Assessment and specification of general characteristics of installations (supply types, continuity requirements, utilisation categories).
• Definitions and terminology aligned with IEC vocabulary for consistent interpretation.
• Requirements for protection against electric shock (basic and fault protection) and selection of protective measures.
• Guidance on earthing/grounding systems, protective conductors and earthing arrangements.
• Principles for selection and application of equipment and devices within installations.
• Requirements for operation, inspection, verification and maintenance to ensure proper functioning and safety.
• Cross‑references to related parts of the IEC/GOST 60364/30331 series for detailed rules on protection against specific hazards (overcurrent, thermal effects, overvoltages, EMC, etc.).

Typical use and users

GOST 30331.1-2013 is used by electrical engineers and designers preparing project documentation, installers and commissioning teams, inspection and certification bodies, maintenance personnel, building services consultants, educators and trainers, and regulatory authorities. It provides the foundational principles applied across more specific parts of the low-voltage installation rules and is consulted when setting requirements for safe, reliable and code-compliant electrical work.

Related standards

The standard is part of the GOST 30331 series (which implements the IEC 60364 family). Closely related documents include other parts of the GOST 30331 series covering protection for safety (overcurrent, thermal effects, isolation and switching), selection and erection of equipment (parts corresponding to IEC 60364‑4 and IEC 60364‑5 subparts), and standards referenced within the text (for example IEC 60038, IEC 60050 series, IEC 60364‑4‑41, IEC 60364‑5‑51/52/53/54, and IEC 62305 on lightning protection). Nationally, earlier documents such as GOST R 50571.x series were superseded where indicated.

FAQ

Q: What is this standard?

A: GOST 30331.1-2013 is the Russian (GOST) standard that defines fundamental principles, general characteristics assessment and terminology for low-voltage electrical installations. It implements and adapts the content of IEC 60364‑1:2005 for use within the GOST system.

Q: What does it cover?

A: It covers objectives and basic rules for the design, erection and verification of low-voltage electrical installations (up to 1 000 V a.c. / 1 500 V d.c.), provides definitions and procedures for assessing general characteristics of installations, and sets out the high‑level principles used across more detailed parts of the installation rules (protection measures, earthing, equipment selection, inspection and testing).

Q: Who typically uses it?

A: Electrical designers, installation contractors, commissioning engineers, inspection and certification bodies, maintenance teams, building services consultants, educators and regulatory authorities use this Part 1 as the normative basis for applying the more specific technical requirements found in later parts of the series.

Q: Is it current or superseded?

A: As published, GOST 30331.1-2013 is the active national implementation of the IEC 60364‑1:2005 edition; it was registered in November 2013 and came into force 1 July 2015. Users should check national publication repositories or the competent standardisation body for any amendments, corrigenda or later revisions and for alignment with newer international editions if required for a specific project.

Q: Is it part of a series?

A: Yes — it is Part 1 of the GOST 30331 series (the national implementation of the IEC 60364 series). Other parts of the series address protection for safety, selection and erection of equipment, wiring systems, protection against overvoltages and EMC, and related technical topics.

Q: What are the key keywords?

A: Low-voltage installations, electrical installation design, earthing/grounding, protection against electric shock, IEC 60364, equipment selection, inspection and verification, safety objectives.
