    Preface This is the harmonized ANCE, CSA Group, and UL standard for Low-voltage switchgear and controlgear - Part 7-1: Ancillary equipment - Terminal blocks for copper conductors. It is the first edition of NMX-J-538/7-1-ANCE, the first edition of CAN/CSA-C22.2 No. 60947-7-1, and the fourth edition of UL 60947-7-1. This edition of UL 60947-7-1 supersedes the previous edition (s) published on May 6, 2011.? This harmonized standard is based on IEC Publication 60947-7-1: Edition 2 (2002), Low-voltage switchgear and controlgear - Part 7-1: Ancillary equipment - Terminal blocks for copper conductors, as revised by corrigendum (March 2003). IEC 60947-7-1 is copyrighted by the IEC.? Scope 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? - 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.? 1.1DV D2 Modification to add the following:? 1.1DV.1 This Standard 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, in accordance with Annex DVB, National Electrical Code, NFPA 70 (for use in the USA), or CSA C22.1-15 Canadian Electrical Code, Part I (for use in Canada), and NOM-001-SEDE, Electrical Installations (Utility) ([for use in Mexico]).? 1.1DV.2 The wire range for terminal blocks covered by this standard include 0,051 mm2 to 1 010 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.3 The voltage range includes up to 1 500 Vac and 1 500 Vdc.
