30、nectors. It is the third edition of NMX-J-548-ANCE, the third edition of CSA C22.2 No. 188, and the sixth edition of UL 486C. This edition of NMX-J-548 cancels the previous edition published in 2008. This edition of CSA C22.2 No. 188 supersedes the previous edition published in 2004. This edition of
31、 UL 486C supersedes the previous edition published in 2004. This harmonized standard was prepared by the Association of Standardization and Certication (ANCE), the CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee for Connectors, of
32、the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), are gratefully acknowledged. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This standard was reviewed by the CSA Integrated Commit
33、tee on Electrical Connectors, under the jurisdiction of the CSA Technical Committee on Wiring Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been approved by the American Nation
34、al Standards Institute (ANSI) as an American National 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 n
35、ote 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 to be considered equivalent to, an IEC standard. This standard is published as an equival
36、ent 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 recognized as being in accordance with NAFTA Artic
37、le 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 changes. Reasons for differences from IEC The Tec
38、hnical Harmonization Committee identied several IEC standards that address electrical 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
39、 and cables in many discrete IEC standards. The THC determined the safe use of electrical 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 inve
40、stigation would be facilitated by the harmonization of the North American electrical codes for wire connectors with IEC installation practices.

41、SION FROM UL 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 standards development organization. If more than one
42、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. ANCE effective date The effective date for ANCE will be announced through the Diario Ocial de Ia Federacin (O
43、fficial Gazette) and is indicated on the cover page. CSA Group effective date The effective date for CSA Group will be announced through CSA Informs or a CSA Group certication notice. UL effective date As of February 28, 2014, all products Listed or Recognized by UL must comply with the requirements
44、 in this standard. A UL effective date is one established by Underwriters Laboratories Inc. and is not part of the ANSI approved standard.

45、 FROM UL 1 Scope 1.1 This Standard applies to single-polarity, hand- or tool-applied splicing wire and cable connectors intended for use with all alloys of copper, aluminum conductors, or copper-clad aluminum conductors, or all three, in accordance with the Canadian Electrical Code Part I, C22.1, in
46、 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 are for use only in the United States in accordance with the National Electrical Code, NFPA 70. a)
47、 connectors intended to hold two or more conductor(s); b) connectors intended for use in appliances and equipment that comply with the requirements for such appliances and equipment; c) connectors intended for use with 6 AWG (13.3 mm 2 ) or smaller conductors; and d) uninsulated connectors that are
48、used in circuits rated 8 000 V and less. Note: Examples of splicing wire connectors include twist-on connectors, insulation-piercing or displacement connectors, spring-action connectors, tool-applied crimp, mechanical set-screw connectors, etc. 1.2 This Standard is intended for splicing wire connect
49、ors 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 mm 2 ) solid; 2) 12 AWG (3.3 mm 2 ) to 6 AWG (13.3 mm 2 ) stranded, Class B concentric, compressed, and compact; and 3) 12 AWG (3.3 mm 2 ) to 6 AWG (13.3 mm 2 ) stranded single input wire (SIW). In Mexico, the use of aluminum conductors is permitted only with thermoset insulation and for sizes of 6 AWG (13.3 mm 2 ) and higher. b) Cop
