Overview

HD 60364-5-51:2009/A12:2017 is a key European Harmonization Document issued by the CENELEC European Committee for Electrotechnical Standardization. This standard focuses on the selection and erection of electrical equipment in building installations, providing common rules to ensure safety, reliability, and compliance with electrical regulations across European countries. It is part of the widely recognized HD 60364 series which governs low-voltage electrical installations.

This 2017 amendment (A12) updates the 2009 version, aligning with the latest safety requirements and practical guidelines. It has been endorsed by CENELEC members and must be implemented nationally by May 2018, with conflicting national standards withdrawn by May 2020, emphasizing its mandatory nature for electrical installation practices in buildings.

Key Topics

• Common Rules for Electrical Equipment Selection
  Defines the criteria for choosing electrical apparatus including socket outlets, plugs, switchgear, and controlgear assemblies with regard to rated currents and protection coordination.

• Erection and Installation Practices
  Specifies the installation conditions and spatial requirements for switchgear assemblies to enhance accessibility and safety. This includes minimum free areas for maintenance and operation.

• Marking and Identification
  Mandates clear, unambiguous marking of electrical equipment such as overcurrent protective devices and wiring systems for straightforward identification during inspections, maintenance, and troubleshooting.

• Protective Conductors and Safety Measures
  Sets detailed requirements for protective conductors including mandatory green/yellow color coding and conditions when they may be applied, focused on preventing electric shock hazards.

• Country-specific Deviations (Denmark Example)
  Outlines specific national deviations reflecting local executive orders (e.g., Denmark's Executive Order no. 1082/2016) which specify additional rules on socket outlets, hospital equipment connections, safety signage, and bonding conductors.

---

Applications

• Building Electrical Installation Design
  Ensures electrical engineers and designers apply consistent and harmonized rules for selecting and installing electrical equipment in residential, commercial, and institutional buildings.

• Safety Compliance and Inspection
  Supports regulatory bodies and inspection agencies in verifying adherence to electrical installation safety standards and marking requirements.

• Manufacturing and Product Development
  Guides manufacturers of electrical equipment and devices on the requirements to meet when designing products intended for fixed installation in buildings.

• Installation and Maintenance
  Provides electricians and maintenance professionals with clear instructions on the proper erection, connection, and identification of electrical components to maintain operational safety and continuity.

---

Related Standards

• HD 60364 Series
  Covers various aspects of low-voltage electrical installations including protection against electric shock, wiring systems, earthing arrangements, and testing procedures.

• CENELEC Internal Regulations
  Outline the process for adopting and implementing harmonized electrotechnical standards throughout Europe.

• National Electrical Safety Regulations
  Each country may have additional regulations implementing or adapting the harmonized standard, such as Denmark’s Executive Order no. 1082/2016 that specifies deviations and additional requirements.
