28、HOUT PERMISSION FROM UL PREFACE This is the harmonized ANCE, CSA Group, and UL standard for Wire Connectors. It is the fourth edition of NMX-J-543-ANCE, the sixth edition of CSA-C22.2 No. 65, and the third edition of UL 486A-486B. This edition of NMX-J-543-ANCE supersedes the previous edition publis

29、hed on January 11, 2013. This edition of CSA-C22.2 No. 65 supersedes the previous edition published on January 11, 2013. This edition of UL 486A-486B supersedes the previous edition published on January 11, 2013. This harmonized standard was prepared by the Association of Standardization and Certica

30、tion (ANCE), CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee for Connectors, of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged. This Standard is c

31、onsidered suitable for use for conformity assessment within the stated scope of the Standard. The present Mexican standard was developed by the SC 20D - Conectadores part of the CT 20 - Conductores from the Comite de Normalizacion de la Asociacion de Normalizacion y Certicacion, A.C., CONANCE, with

32、the collaboration of the connectors manufacturers and users. This standard was reviewed by the CSA Subcommittee on Wiring Devices for Household and General Use, under the jurisdiction of the CSA Technical Committee on Wiring Products and the CSA Strategic Steering Committee on Requirements for Elect

33、rical Safety, and has been formally approved by the CSA 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 appr

34、oved by the American National Standards Institute (ANSI) 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 st

35、andard is stated in its scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. Level of harmonization This standard uses the IEC format but is not based on, nor is it considered equivalent to, an IEC stand

36、ard. 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 those recog

37、nized 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 editorial chan

38、ges. APRIL 27, 2018 NMX-J-543-ANCE CAN/CSA-C22.2 NO. 65-18 UL 486A-486B 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Reasons for differences from IEC The Technical Harmonization Committee identied several IEC standards that address elect

39、rical wire connectors included in the scope of this standard. The IEC standards for electrical wire connectors are recognized as being generally system specic, containing the requirements for the relevant wire connectors and cables in many discrete IEC standards. The THC determined the safe use of e

40、lectrical wire connectors is dependent on the design and performance of the wire connectors in relation to the North American Electrical Codes with which they are intended to be installed. The THC agreed such future investigation will be facilitated by the harmonization of the North American Electri

41、cal Codes for wire connectors with IEC installation practices. 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 standard in accordance with the procedural rules of the sta

42、ndards 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.

44、between current-carrying parts, in accordance with the Canadian Electrical Code, Part I, C22.1, in Canada, the National Electrical Code, NFPA-70, in the United States of America, or the Standard for Electrical Installations, NOM-001-SEDE, in Mexico, as follows: Note: Copper-clad aluminum conductors

45、are for use only in the United States in accordance with the National Electrical Code, NFPA 70. a) Pressure wire connectors intended to hold one or more conductor(s); b) Connectors intended for use in appliances and equipment that comply with the requirements for such appliances and equipment; c) So

46、ldering connectors; d) Splicing wire connectors intended for use with 4 AWG (21.2 mm 2 ) or larger conductors; Note: A splicing wire and cable connector taking a range of conductor sizes may include conductor sizes smaller than 4 AWG (21.2 mm 2 ). e) Neutral bars; f) Uninsulated connectors that are

47、used in circuits rated 35 000 V and below; g) Ampere-rated connectors not intended for general use; and h) Insulation piercing connectors. 1.2 This Standard is intended for connectors suitable for use with conductors in the size ranges as follows: a) Aluminum: 1) 12 AWG (3.3 mm 2 ) and 10 AWG (5.3 m
