Connecting Devices - Electrical Copper Conductors - Safety Requirements for Screw-Type and Screwless-Type Clamping Units - Part 1: General Requirements and Particular Requirements for Clamping Units for Conductors from 0,2 mm Squared up to 35 mm Squared (Included)
|Publication Date:||1 November 1999|
|ICS Code (Connecting devices):||29.120.20|
This part of IEC 60999 applies to screw-type and screwless-type clamping units for connecting devices, either as separate entities or as integral parts of equipment, for the connection of electrical copper conductors (complying with IEC 60228), rigid (solid or stranded) and/or flexible, having a cross-sectional area of 0,2 mm2 up to and including 35 mm2 and equivalent AWG sizes with a rated voltage not exceeding 1 000 V a.c. with a frequency up to and including 1 000 Hz, and 1 500 V d.c.
It applies to clamping units primarily suitable for connecting unprepared conductors.
This standard does not apply to clamping units
a) for connection by crimping or soldering;
b) for data and signalling circuits;
c) for flat quick-connect terminations, insulation-piercing connecting devices and twist-on connecting devices, which are covered by IEC 61210 1), IEC 60998-2-3  and IEC 60998-2-4  respectively.
