Draft Scope/Description:

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 on to 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 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.

1.4 These ferrules are intended to be terminated in wire connection devices rated for copper Class B and C conductors.

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 intended for installation using only crimping tools as specified by the ferrule’s manufacturer.

1.7 These ferrules are not intended for use in other types of connectors, including, but not limited to, IDC (insulation displacement connection) connectors.

1.8 This standard does not apply to Wire connectors such as pin adapters covered in CSA C22.2 No. 65 / UL486A-486B.

1.9 The values given in SI (Metric) units are normative, except for AWG / kcmil conductor sizes. Any other values are for information and comparison only.
