Preface This is the harmonized CSA Group and UL standard for Large Ferrules . It is the first edition of CSA C22.2 No. 342 and the first edition of UL 486L. This harmonized standard was prepared by CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Subcommittee, CANENA Technical Harmonization Committee 99 – Electrical 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. This standard was reviewed by the CSA Integrated Committee 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 developed in compliance with the Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
Scope
1.1 This standard applies to bare and covered ferrules intended for field wiring and factory wiring for use in accordance with the National Electrical Code, ANSI/NFPA-70, and Canadian Electrical Code, Part I, CSA C22.1.
1.2 Ferrules covered by this standard are intended to facilitate the connection of stranded wire onto devices, such as terminal blocks and mechanical wire connectors, and to treat stripped wire and prevent turned back strands during installation.
1.3 These ferrules are intended to be terminated in wire connection devices rated for copper Class B and C conductors.
1.4 These ferrules are suitable for use with 2/0 AWG to 750 kcmil, 70 mm2 to 380 mm2 copper conductors that are more finely stranded than Class B or C conductors. Note: Examples of stranding classes more finely stranded than class B or C are classes G, H, I, K, M, DLO, 5, and 6.
1.5 These ferrules are intended for use in aluminum and copper body mechanical connectors with dome and conical shaped screws that apply direct pressure to the conductor being terminated.
1.6 These ferrules are not intended for use in other types of connectors, including, but not limited to, IDC (insulation displacement connection) connectors.
1.7 This standard does not apply to wire connectors such as pin adapters covered in CAN/CSA C22.2 No. 65 / UL 486A-486B.
