1 Scope<\/b><\/p>\n

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<\/sup> and 300 mm2<\/sup> (AWG 24\/600 kcmil), intended to be used in circuits of a rated voltage not exceeding 1\u00a0000 V a.c. up to 1\u00a0000 Hz or 1\u00a0500 V d.c.<\/p>\n<\/p>\n

NOTE AWG is the abbreviation of \u201cAmerican Wire Gage\u201d (Gage (US) = Gauge (UK))<\/p>\n<\/p>\n

kcmil = 1000 cmil;<\/p>\n<\/p>\n

1 cmil = 1 circular mil = surface of a circle having a diameter of 1 mil<\/p>\n<\/p>\n

1 mil = 1\/1000 inch<\/p>\n<\/p>\n

This standard may be used as a guide for<\/p>\n<\/p>\n

  1. \n

    \u2013 terminal blocks requiring the fixing of special devices to the conductors, for example quick connect terminations or wrapped connections, etc.;<\/p>\n<\/li>\n

  2. \n

    \u2013 terminal blocks providing direct contact to the conductors by means of edges or points penetrating the insulation, for example insulation displacement connections, etc.;<\/p>\n<\/li>\n

  3. \n

    \u2013 special types of terminal blocks, for example disconnect terminal blocks, etc.<\/p>\n<\/li>\n<\/ol>\n

    Where applicable in this standard, the term \u201cclamping unit\u201d has been used instead of the term \u201cterminal\u201d. This is taken into account in case of reference to IEC 60947-1.<\/p>\n
