00486f-000000-0000001 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, NFPA 70 and Canadian Electrical Code, Part I, CSA C22.1.
1.2 This standard applies to ferrules that 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 When intended for use with one conductor, these ferrules are suitable for use with 777 kcmil – 26 AWG, 380 – 0.14 mm2, stranded copper conductors. For conductor sizes 8 AWG, 10 mm2 or larger, these ferrules are suitable for use with stranded 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, 5, and 6. In addition, Type DLO cable is more finely stranded than Class B or C.
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 This standard applies to ferrules that are intended to be terminated in wire connection devices rated for:
a) Solid copper conductors; and/or
b) Stranded copper Class B and C conductors – applicable to wire connection devices rated to terminate conductor sizes 8 AWG, 10 mm2 or larger.
1.6 Ferrules covered by this standard are not intended for use in IDC (insulation displacement connection) terminal blocks.
1.7 This Standard applies to Ferrules rated for use with conductor sizes 2/0 AWG, 70 mm2 or larger that 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.
1.8 This standard does not apply to wire connectors such as pin adapters covered in CSA C22.2 No. 65 or UL 486A-486B.
1.9 Ferrules covered by this standard may be used with equipment having short circuit ratings of:
a) 85,000 A maximum, or
b) 100,000 A maximum if supplied by an overcurrent protective device, and the equipment short-circuit current rating, divided by the number of conductors per phase, results in a current of 50,000 A or less per conductor.
