29、.2 NO. 188-18 UL 486C 4UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Preface This is the harmonized ANCE, CSA Group, and UL standard for Splicing Wire Connectors. It is the fourth edition of NMX-J-548-ANCE, the fourth edition of CSA C22.2

30、No. 188, and the seventh edition of UL 486C. This harmonized standard has been jointly revised on January 20, 2016. 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 t

31、he 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 considered suitable for use for conformity assessment within the stated scope of the Standard.

32、 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 the collaboration of the connectors manufacturers and users. This standard was reviewed by th

33、e 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 Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard ha

34、s 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) as an American National Standard. Ap

35、plication 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 that it remains the responsibility of

36、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 equivalent standard for ANCE, CSA Group, and UL.

37、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 Article 905, for example, because of fundamenta

38、l 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. JANUARY 26, 2018 NMX-J-548-ANCE CSA C22.2 NO. 188-18 UL 486C 5UL COPYRIGHTED MATER

39、IAL 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 electrical wire connectors included in the scope of this standard. The IEC standards for electrica

40、l 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 electrical wire connectors is dependent on the design and performance of the wire connectors i

41、n relation to the North American electrical codes with which they are intended to be installed. The THC agreed such future investigation would be facilitated by the harmonization of the North American electrical codes for wire connectors with IEC installation practices. Interpretations The interpret

42、ation 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 interpretation of the literal text has bee

43、n 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、ERMISSION 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,

45、 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 are for use only in the United States in accordance with the National Electrical Code, N

46、FPA 70. a) 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; d) Uninsulated connectors tha

47、t are used in circuits rated 8 000 V and less; and e) Connectors intended for use in air-handling spaces. Note: Examples of splicing wire connectors include twist-on connectors, insulation-piercing or displacement connectors, spring-action connectors, tool-applied crimp, mechanical set-screw connect

48、ors, etc. 1.2 This Standard is intended for splicing wire 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 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

49、 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) Copper-clad aluminum: 1) In Canada, this construction is not allowed. 2) In Mexico, this construction is not allowed. 3) In the United States: i) 12 AWG (3.3 mm 2 ) and 10 AWG (5.3 mm 2 ) solid; and ii) 12 AWG (3.3 mm 2 ) to 6 AWG (13
