UL 60947-7-1-2011 UL Standard for Safety Low-voltage switchgear and controlgear – Part 7-1: Ancillary equipment – Terminal blocks for copper conductors (Third Edition; Reprint with revisions through and including October 14@ 2011)
"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.c. 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. 1.1DV.1 D2 Modification by adding the following: 1.1DV.1.1 This standard also applies to terminal blocks that have insulation piercing or displacement clamping units. 1.1DV.1.2 The wire range for terminal blocks covered by this standard include 0@051 mm2 to 1 1010 mm2 (30 AWG to 2 000 kcmil) copper conductors and 3@31 mm2 to 1 010 mm2 (12 AWG to 2 000 kcmil) aluminum conductors. See Annex DVA for aluminum requirements. In Mexico@ 3@31 mm2 (12 AWG)@ 5@26 mm2 (10 AWG)@ and 8@37 mm2 (8 AWG) aluminum conductors are not allowed. 1.1DV.1.3 The voltage range includes up to 1 500 V ac and 1 500 V dc. 1.1DV.2 DC Modification (Applicable for the United States): 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 in accordance with the Outline of Investigation for Power Distribution Blocks@ Subject 1953."
