UL 60947-7-1 BULLETIN-2014 UL Standard for Safety Low-voltage switchgear and controlgear – Part 7-1: Ancillary equipment – Terminal blocks for copper conductors (COMMENTS DUE: December 1@ 2014)
"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 1 000 V a.c. up to 1 000 Hz or 1 500 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 ?C terminal blocks requiring the fixing of special devices to the conductors@ for example quick connect terminations or wrapped connections@ etc.; ?C terminal blocks providing direct contact to the conductors by means of edges or points penetrating the insulation@ for example insulation displacement connections@ etc.; ?C 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."
