Scope:

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, 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 during 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

 

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. 65 or UL 486A-486B.

Project need:

This is a bi-national standard that CSA and UL has agreed on. The intent of the project is to produce new harmonized requirements for both, Canadian and US industries.
