Full title and description

Electromagnetic compatibility (EMC) - Part 5: Installation and mitigation guidelines - Section 2: Earthing and cabling (IEC TR 61000-5-2:1997). This technical report gives guidance on earthing (grounding) practices, cabling arrangements and related installation measures intended to reduce electromagnetic interference and improve EMC of electrical and electronic installations in industrial, commercial and residential environments.

Abstract

IEC TR 61000-5-2:1997 is a guidance document produced by IEC TC 77 that explains principles and practical measures for earthing, bonding, cable routing and screening to achieve and maintain electromagnetic compatibility. It addresses topics such as earthing topologies, bonding techniques, cable separation and routing, screening and transfer impedance, and provides recommendations for installers, users and equipment designers to reduce emissions and improve immunity of installations.

Scope

The report provides installation-level guidance to minimise EMC problems arising from earthing and cabling practices. It is concerned with the way earthing systems are implemented, how conductors and cables are routed and separated, the use of screening and bonding, and how these choices affect coupling (both common-mode and differential-mode) between sources and susceptible equipment. The scope covers industrial, commercial and residential installations and is intended primarily for installers, site engineers, EMC practitioners and to some extent equipment manufacturers.

Key topics and requirements

• Principles of earthing and bonding: earthing topologies, equipotential bonding and reduction of loop areas.
• Cable routing and segregation: separation of power, control and signal cables; routing to minimise coupling.
• Screening and shielding: selection and installation of cable screens, earthing of shields, connector considerations.
• Transfer impedance and surface transfer impedance concepts for screened cables and coaxial systems.
• Common-mode and differential-mode coupling mechanisms and mitigation techniques.
• Practical installation rules: use of single-point and multi-point bonding where appropriate, cable trays, conduits and earthing conductors.
• Recommendations for testing, measurements and verification of earthing/cabling effectiveness in situ.

These key topics are described with explanatory material and practical recommendations rather than normative limits; illustrations and worked examples are included in the report.

Typical use and users

Typical users are EMC engineers, electrical installers, site and facility engineers, consultants, system integrators and manufacturers who need to implement or specify earthing and cabling arrangements that reduce EMI risk. The report is used during design and installation planning, site acceptance testing and troubleshooting of EMC problems in buildings, industrial plants and installations with sensitive equipment.

FAQ

Q: What is this standard?

A: It is an IEC Technical Report (IEC TR 61000-5-2:1997) giving guidance on earthing and cabling practices to support electromagnetic compatibility of installations.

Q: What does it cover?

A: Practical recommendations on earthing/topologies, bonding, cable routing and separation, screening methods, transfer impedance considerations and on-site verification measures to reduce EMI and improve immunity. The report explains principles and installation-level measures rather than prescribing mandatory test limits.

Q: Who typically uses it?

A: EMC engineers, electrical installers and site/facility engineers, system integrators and manufacturers involved in specifying, installing or troubleshooting cabling and earthing for sensitive equipment and systems.

Q: Is it current or superseded?

A: The document is the 1997 first edition (IEC TR 61000-5-2:1997) and remains listed in the IEC catalogue (stability information shows ongoing recognition through current IEC records). Other documents in the Part‑5 series have been updated more recently (for example IEC/TR 61000-5-1 was revised in 2023), so users should check the IEC catalogue for the latest related guidance when planning work.

Q: Is it part of a series?

A: Yes — it is Section 2 of Part 5 (Installation and mitigation guidelines) within the IEC 61000 series on EMC; the Part‑5 set includes multiple sections and related technical specifications dealing with installation, mitigation and HEMP protection topics.

Q: What are the key keywords?

A: Earthing/grounding, bonding, cabling, screening, transfer impedance, EMC, cable routing, common‑mode, differential‑mode, installation guidelines.
