It is the rst edition of CSA C2
21、2.2 No. 291 and the rst edition of UL 486F. This harmonized standard has been jointly revised on August 7, 2015. This harmonized standard was prepared by the CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee for Connectors, of the Cou
22、ncil 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 Subcommittee on Wiring D
23、evices 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 has been approved by the America
24、n 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 standard is stated in
25、 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 standard. This standard
26、is published as an equivalent standard for 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 accordan
27、ce 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 changes. Reasons for differenc
28、es from IEC At present there is no IEC standard for bare and covered ferrules. Therefore, this standard does not employ any IEC standard for base requirements.

29、ION 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 i
30、nterpretation 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. CSA Effective Date The effective date for CSA International will be announced through CSA Informs or a CSA cer
31、tication notice. UL Effective Date A UL effective date is one established by UL LLC and is not part of the ANSI approved standard.

32、 requirements cover bare and covered ferrules intended for eld wiring and factory wiring for use in accordance with the National Electrical Code, ANSI/NFPA-70 and Canadian Electrical Code, CSA C22.1. 1.2 These ferrules are intended to facilitate the connection of stranded wire on to devices, such as
33、 terminal blocks. Their purpose is to treat stripped wire and prevent turned back strands during installation. They are intended to be used to attach to one stranded copper conductor or two stranded copper conductors of the same size. 1.3 These ferrules are suitable for use with 1/0 20 AWG stranded
34、copper conductors. 1.4 These ferrules are intended to be terminated in wire connection devices rated for solid conductors. 1.5 Ferrules are not intended for use in IDC (insulation displacement connection) terminal blocks. 1.6 This standard does not apply to wire connectors such as pin adapters cover
