Low-voltage electrical installations - Part 5-54: Selection and erection of electrical equipment - Earthing arrangements and protective conductors
IEC 60364-5-54:2011 addresses the earthing arrangements and protective conductors including protective bonding conductors in order to satisfy the safety of the electrical installation. This third edition cancels and replaces the second edition, published in 2002, and constitutes a technical revision. The main changes with respect to the previous edition are listed below: - clarification of the definition of protective conductor; - improved specification of mechanical characteristics of the earth electrode; - introduction of earth electrode for protection against electric shock and lighting protection; - annexes describing concrete-embedded foundation earth electrodes and soil-embedded earth electrode. IEC 60364-5-54:2011 has the status of a basic safety publication in accordance with IEC Guide 104. This document also includes requirements regarding earthing and equipotential bonding for information and communication technology (ICT) with the aim of: - reducing the risk of electrical hazards for correct operation of these devices and the information and communication technology wiring; - providing the telecommunication systems with a reliable signal reference plane that can improve resistance to electromagnetic interference (EMI) by reference to ISO/IEC 30129. NOTE Examples of information and communication technology (ICT) include: - DC supply networks (and systems) for supplying power to ICT equipment within a building; - star-shaped private automatic branch exchanges (PABX) or their equipment; - local area (communication) networks (LANs); - fire and intruder alarms communication systems; - building automation systems, e.g. direct digital control systems; - systems for computer-aided manufacturing (CAM) and other computer-aided services; - broadcast and communication technology.

Overview
HD 60364-5-54:2011/A1:2022 (CLC) is the European harmonization of IEC 60364-5-54 covering earthing arrangements and protective conductors for low-voltage electrical installations. This third edition (technical revision of the 2002 version) defines requirements for earthing, protective bonding conductors and earth electrodes to ensure electrical safety and reliable operation of equipment, including information and communication technology (ICT) systems. Amendment A1 (2022/2023) clarifies definitions and adds guidance on earth electrodes and national conditions.
Key topics and requirements
- Scope: Selection and erection of electrical equipment concerned with earthing arrangements, protective conductors and equipotential bonding in low-voltage installations.
- Definitions clarified: Improved definition of the protective conductor to reduce ambiguity in design and installation.
- Earth electrodes: Enhanced specification of mechanical characteristics; introduction of earth electrodes specifically addressing protection against electric shock and lightning.
- Annexes: Practical guidance on concrete-embedded foundation earth electrodes and soil-embedded earth electrodes.
- ICT earthing and bonding: Requirements to reduce electrical hazards for ICT devices and to provide a reliable signal reference plane that improves resistance to electromagnetic interference (EMI), with cross-reference to ISO/IEC 30129.
- Safety status: Recognised as a basic safety publication per IEC Guide 104; national implementation and special national conditions are included (examples: Hungary’s reference to MSZ 18014 for foundation electrodes, and Estonia’s prohibition on using water/sewer pipes as earth electrodes).
Applications and users
This standard is practical for professionals involved in the design, installation and verification of low-voltage earthing systems:
- Electrical designers and consulting engineers specifying earthing arrangements
- Installers and electricians implementing protective conductors and earth electrodes
- Building services and facilities engineers integrating earthing into power and ICT systems
- Safety managers, inspectors and authorities responsible for compliance and testing
- ICT infrastructure and telecommunications engineers concerned with equipotential bonding and EMI mitigation
Practical benefits include improved electrical safety, clearer installation practices for earthing systems, and enhanced immunity of ICT and communication systems to electromagnetic interference.
