Overview
EN 60999-1:2000 (CLC adoption of IEC 60999-1:1999) specifies safety requirements for connecting devices that use screw-type and screwless-type clamping units for electrical copper conductors. The standard applies to standalone clamping units or those integrated into equipment, for copper conductors (rigid or flexible) conforming to IEC 228 with cross-sectional areas from 0.2 mm² up to 35 mm² (included). Rated voltages covered are up to 1 000 V a.c. (≤1 000 Hz) and 1 500 V d.c. EN 60999-1:2000 carries the status of a group safety publication per IEC Guide 104.
Key Topics
- Scope and applicability: Defines conductor types (rigid, stranded, flexible) and the conductor size range (0.2 mm²–35 mm²) including equivalent AWG sizes.
- Types of clamping units: Covers both screw-type and screwless-type clamps used in connecting devices.
- Safety requirements: Addresses essential safety aspects for clamping units used in electrical connections, including requirements related to:
- Conductor accommodation and secure clamping
- Electrical rating limits (voltage and frequency)
- Integration as separate parts or as part of equipment
- Compliance context: Establishes consistency with IEC 60999-1:1999 and references conductor standards (IEC 228) and IEC Guide 104 for group safety publication status.
Applications and Who Uses It
EN 60999-1:2000 is relevant to professionals and organizations involved in the design, manufacture, testing, installation and certification of electrical connection components:
- Terminal block and connector manufacturers designing screw or spring/clamp systems for copper conductors
- Switchgear and distribution board designers integrating clamping units into assemblies
- Electrical equipment manufacturers (lighting, appliances, control gear) specifying internal connections
- Test laboratories and conformity assessors verifying compliance with safety requirements
- Electrical installers and specifiers selecting appropriate connectors for building and industrial wiring
Using this standard helps ensure safe, consistent connections for copper conductors across building, industrial and appliance applications, reducing risk of loose connections and electrical hazards.
