This part of IEC 60947 specifies requirements for terminal blocks with screw-type or screw-less-type clamping units primarily intended for industrial or similar use and to be fixed to a support to provide electrical and mechanical connection between copper conductors. It applies to terminal blocks intended to connect round copper conductors, with or without special preparation, having a cross-section between 0,2 mm2 and 300 mm2 (AWG 24/600 kcmil), intended to be used in circuits of a rated voltage not exceeding 1000 V a.c. up to 1000 Hz or 1500 V d. NOTE: AWG is the abbreviation of "American Wire Gage" (Gage (US) = Gauge (UK)) kcmil = 1000 cmil; 1 cmil = 1 circular mil = surface of a circle having a diameter of 1 mil 1 mil = 1/1000 inch. This standard may be used as a guide for - terminal blocks requiring the fixing of special devices to the conductors, for example quick connect terminations or wrapped connections, etc.; - terminal blocks providing direct contact to the conductors by means of edges or points penetrating the insulation, for example insulation displacement connections, etc.; - special types of terminal blocks, for example disconnect terminal blocks, etc. Where applicable in this standard, the term "clamping unit" has been used instead of the term "terminal". This is taken into account in case of reference to IEC 60947-1. 1.1 Addition: This standard applies to insulation displacement terminals. 1.1 Addition: AWG range expanded to include AWG 30 to 2,000 kcmil. 1.1 Addition: See Annex dva for Aluminum Requirements. 1.1 Addition: Voltage range expanded to include up to 1,500 Vac. Note: These requirements do not cover field installed power distribution blocks intended to distribute power in a building to separate units such as apartments, separate heaters, and air conditioning units. Power distribution blocks are investigated to Subject 1953, Outline of Investigation for Power Distribution Blocks.
