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 228), rigid (solid or stranded) and/or flexible, having a cross-sectional area of 0.5 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. Has the status of a group safety publication in accordance with IEC Guide 104.
