UL 486F:2019-09 Bare and Covered Ferrules

UL 486F:2019-09 Bare and Covered Ferrules. 1.1 These requirements cover 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 These ferrules are intended to facilitate the connection of stranded wire on to devices, such as terminal blocks. Their purpose is to treat stripped wire and prevent turned back strands dunng 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 When intended for use with one conductor, these ferrules are suitable for use with 1/0—26 AWG, 50 — 0.14 mm2 , stranded copper conductors. 1 .4 When intended for use with two conductors, these ferrules are suitable for use with (2) 6 — (2) 26 AWG, (2)16— (2) 0.25 mm2, stranded copper conductors. 1 .5 These ferrules are intended to be terminated in wire connection devices rated for solid conductors. 1 .6 Ferrules are not intended for use in IDC (insulation displacement connection) terminal blocks. 1.7 This standard does not apply to wire connectors such as pin adapters covered in CSA C22.2 No. 65 or UL 486A-486B. 1.8 In Canada, general requirements applicable to this Standard are provided in CAN/CSA-C22.2 No. 0. 2 Reference Publications 2.1 Normative references Where reference is made to any Standards, such reference shall be considered to refer to the latest editions and revisions thereto available at the time of printing, unless otherwise specified. 2.1.1 CSA Group Standards C22.1-18 Canadian Electrical Code.

Any other values given are for information only. 3.2 AWG is the normative wire size of the standard. The mm2 is the closest equivalent to that size. 4 Definitions For the purpose of this Standard, the following terms and definitions apply. 4.1 Covered — Encased within material of composition or thickness that is not recognized as electrical insulation. 4.2 Covered ferrule — A ferrule provided with a plastic sleeve. 4.3 Ferrule — A conductive sleeve used to facilitate the termination of stranded wire in devices...
