UL 486F:2014 free download Bare and Covered Ferrules
1 Scope
1.1 These requirements cover bare and covered ferrules intended for field wiring and factory wiring foruse in accordance with the National Electrical Code, ANSINFPA-70 and Canadian Electrical Code, cSAC22.1.
1.2 These ferrules are intended to facilitate the connection of stranded wire on to devices, such asterminal 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 copperconductors of the same size.
1.3 These ferrules are suitable for use with 1/0 – 20 AWG stranded 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 covered in CSA C22.2 No.65or UL 486A-486B.
