28、ment Terminal blocks for copper conductors. It is the rst edition of NMX-J-538/7-1-ANCE, the rst 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

29、 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. This harmonized standard was prepared by the Association of St

30、andardization and Certication (ANCE), CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee for Industrial Control Equipment, of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are

31、gratefully acknowledged. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. The Mexican Standard was developed by the CT PIE-A from the Comite de Normalizacion de la Asociacion de Normalizacion y Certicacion, A.C., CONANCE, with the collab

32、oration of the manufacturers and users. This standard was reviewed by the CSA Subcommittee on Terminal Assemblies, under the jurisdiction of the CSA Technical Committee on Industrial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approv

33、ed by the CSA Technical Committee. This standard has been approved as a National Standard of Canada by the Standards Council of Canada (SCC). This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Application of Standard Where reference

34、is made to a specic number of samples to be tested, the specied number is to be considered a minimum quantity. Note: Although the intended primary application of this standard is stated in its scope, it is important to note that it remains the responsibility of the users of the standard to judge its

35、 suitability for their particular purpose. This is the NMX-J-538/7-1-ANCE Standard for Safety for Low-voltage switchgear and controlgear Part 7-1: Ancillary equipment Terminal blocks for copper conductors. This NMX-J-538/-1-ANCE Part 1 is to be used in conjunction with the appropriate NMX-J-538/7-1-

36、ANCE Part 2 and 3, which contains clauses to supplement or modify the corresponding clauses in the Part 1, to provide relevant requirements for each type of product.

Level of harmonization This standard adopts the IEC text

40、with national differences. This standard is published as an equivalent standard for ANCE, CSA Group, and UL. An equivalent standard is a standard that is substantially the same in technical content, except as follows: Technical national differences are allowed for codes and governmental regulations

41、as well as those recognized as being in accordance with NAFTA Article 905, for example, because of fundamental climatic, geographical, technological, or infrastructural factors, scientic justication, or the level of protection that the country considers appropriate. Presentation is word for word exc

42、ept for editorial changes. All national differences from the IEC text are included in the ANCE, CSA Group and UL versions of the standard. While the technical content is the same in each organizations version, the format and presentation may differ. Reasons for differences from IEC National differen

43、ces from the IEC are being added in order to address safety and regulatory situations present in the US, Canada and Mexico. Interpretations The interpretation by the standards development organization of an identical or equivalent standard is based on the literal text to determine compliance with th

44、e standard in accordance with the procedural rules of the standards development organization. If more than one interpretation of the literal text has been identied, a revision is to be proposed as soon as possible to each of the standards development organizations to more accurately reect the intent
