28、UL PREFACE This is the harmonized ANCE, CSA Group, and UL standard for Low-Voltage Switchgear and Controlgear - Part 7-4: Ancillary Equipment - PCB Terminal Blocks for Copper Conductors. It is the First edition of NMX-J-538/7-4-ANCE, CAN/CSA-C22.2 No. 60947-7-4, and UL 60947-7-4. This harmonized sta
29、ndard is based on IEC Publication 60947-7-4: Edition 1 (2013), Low-voltage switchgear and controlgear - Part 7-4: Ancillary equipment - PCB terminal blocks for copper conductors, issued August 2013. IEC 60947-7-4 is copyrighted by the IEC. This harmonized standard was prepared by the Association of
30、Standardization and Certication (ANCE), CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Subcommittee, THSC 121A WG5, of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully ac
31、knowledged. 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 collaboration of th
32、e 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 approved by the CSA
33、 Technical Committee. This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. This standard has been approved by the American National Standards Institute (ANSI
34、) as an American National Standard. Application of Standard Where reference 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
35、that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. This is the NMX-J-538/7-4-ANCE standard for Low-Voltage Switchgear and Controlgear - Part 7-4: Ancillary Equipment - PCB Terminal Blocks for Copper Conductors. This NMX-J-538/7-4-AN
36、CE Part 4 is to be used in conjunction with the rst edition of NMX-J-538/7-1-ANCE. The requirements for Ancillary Equipment - PCB Terminal Blocks for Copper Conductors are contained in this Part 4 Standard and NMX-J-538/7-1-ANCE. Requirements of this Part 4 Standard, where stated, amend the requirem
37、ents of NMX-J-538/7-1-ANCE. Where a particular subclause of NMX-J-538/7-1-ANCE is not mentioned in NMX-J-538/7-4-ANCE, the NMX-J-538/7-1-ANCE subclause applies. This is the CAN/CSA-C22.2 No. 60947-7-4 Standard for Low-Voltage Switchgear and Controlgear Part 7-4: Ancillary Equipment PCB Terminal Bloc
38、ks for Copper Conductors. This CSA Group Part 4 is to be used in conjunction with the rst edition of CAN/CSA-C22.2 No. 60947-7-1. The requirements for Ancillary Equipment PCB Terminal Blocks for Copper Conductors are contained in this Part 4 Standard and CAN/CSA-C22.2 No. 60947-7-1. Requirements of
39、this Part 4 Standard, where stated, amend the APRIL 27, 2018 NMX-J-538/7-4-ANCE CAN/CSA-C22.2 NO. 60947-7-4:18 UL 60947-7-4 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL requirements of CAN/CSA-C22.2 No. 60947-7-1. Where a particular subc
40、lause of CAN/CSA-C22.2 No. 60947-7-1 is not mentioned in CAN/CSA-C22.2 No. 60947-7-4, the CAN/CSA-C22.2 No. 60947-7-1 subclause applies. This is the UL standard for Low-Voltage Switchgear and Controlgear - Part 7-4: Ancillary Equipment - PCB Terminal Blocks for Copper Conductors. This UL 60947-7-4,
41、Low-Voltage Switchgear and Controlgear - Part 7-4: Ancillary Equipment - PCB Terminal Blocks for Copper Conductors, is to be used in conjunction with the fourth edition of UL 60947-7-1. The requirements for Ancillary Equipment - PCB Terminal Blocks for Copper Conductors are contained in this Part 4
42、Standard and UL 60947-7-1. Requirements of this Part 4 Standard, where stated, amend the requirements of UL 60947-7-1. Where a particular subclause of UL 60947-7-1 is not mentioned in UL 60947-7-4, the UL 60947-7-1 subclause applies. Level of Harmonization This standard adopts the IEC text with nati
43、onal 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 as well as
44、 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 except for ed
45、itorial 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 Differences from
46、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 the standa
47、rd 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.
