Grandes ferrules

1.1 

These requirements include bare and covered   ferrules intended for field wiring and

factory wiring for use in accordance with the National Electrical Code and ANSI/NFPA-

70 and Canadian Electrical Code (CEC), 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 and mechanical wire connectors. Their purpose is 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 .

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 shaped screws that apply direct pressure to the conductor being terminated. These are not intended for use in other types of connectors including, but not limited to, IDC (insulation displacement connection) connectors.

1.6

This standard does not apply to Wire connectors such as pin adapters covered in ANCE NMX J-543-ANCE, CSA C22.2 No. 65 and UL486A-486B.

1.7

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