Overview
EN 60999-2:2003 (CLC / IEC 60999-2:2003) specifies safety requirements for screw-type and screwless-type clamping units intended for connecting electrical copper conductors with cross-sections above 35 mm² up to and including 300 mm². It applies to clamping units used either as separate connecting devices or as integral parts of equipment, for rigid, stranded and flexible copper conductors that comply with EN/IEC 60228. The standard covers products for systems with rated voltages up to 1 000 V a.c. (≤ 1 000 Hz) and 1 500 V d.c. and is primarily targeted at clamping units suitable for connecting unprepared conductors. EN 60999-2 is intended to be read in conjunction with EN 60999-1:2000 and has the status of a group safety publication per IEC Guide 104.
Key topics and requirements
- Scope and applicability: Defines the conductor sizes (35–300 mm²), permitted conductor types (rigid/stranded/flexible), voltage and frequency limits, and exclusions (e.g., crimped or soldered connections, and certain non‑universal clamping units as defined in EN 60999-1).
- Safety and performance focus: Establishes mandatory safety requirements and test principles that clamping units must meet to ensure reliable electrical connection and safe operation in their intended voltage range.
- Product classification and marking: Covers how clamping units are classified for intended use and the essential information manufacturers should provide (see EN 60999-1 for general marking rules).
- Normative structure: Includes normative annexes (B, C, ZA) and informative annexes (A), and references key standards such as IEC/EN 60228 (conductors) and EN 60999-1.
(Note: EN 60999-2 sets requirements and test principles; specific test methods and numerical parameters are contained in the normative text of the standard and related parts.)
Applications and users
EN 60999-2 is used by:
- Manufacturers of connecting devices, terminal blocks, busbar clamps and screw/screwless clamping units to design and certify products for large copper conductors.
- Switchgear and controlgear designers specifying terminals for power distribution, substations, industrial installations, and renewable energy systems.
- Panel builders and electrical contractors selecting compliant clamping units for high-current connections.
- Testing and certification bodies assessing product conformity with European and IEC safety requirements.
- Procurement and compliance teams creating technical specifications and ensuring safety compliance for conductors up to 300 mm².
