Abstract

Deals with screw-type and screwless type clamping units for connecting devices, as either essential parts of equipment or as separate entities, for connecting of electrical copper conductors (which comply with IEC 60228), rigid (stranded or solid) and flexible, with cross-sectional area of 0,2 mm[2] to 35 mm[2] and equivalent AWG sizes having rated voltages up to 1 000 V a.c. and frequencies not exceeding 1 000 Hz, and 1 500 V d.c. Covers clamping units appropriate for connecting unprepared conductors. Does not deal with those units for connection by soldering or crimping; for data and signalling circuits, and flat quick-connect terminations, twist-on and insulation-piercing connecting devices.
