Preface

This is the harmonized CSA Group and UL standard for Bare and Covered Ferrules. It is the second edition of CSA C22.2 No. 291 and the second edition of UL 486F. This edition of CSA C22.2 No. 291 supersedes the previous edition published in 2014.

The major differences between this edition and the previous edition include editorial updates to Tables 1-6, clarification to dielectric voltage withstand test, addition of wire gauge to marking requirements, expansion of the scope to include wire ranges covered by this standard and updates to the referenced publications.

This standard was reviewed by the CSA Integrated Committee on Electrical Connectors, under the jurisdiction of the CSA Technical Committee on Wiring Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

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, 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. 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 1/0 – 26 AWG, 50 – 0.14 mm2 , stranded copper conductors.

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

These ferrules are intended to be terminated in wire connection devices rated for solid conductors.

1.6

Ferrules are not intended for use in IDC (insulation displacement connection) terminal blocks.

1.7

This standard does not apply to wire connectors such as pin adapters covered in CSA C22.2 No. 65 or UL 486A-486B.

1.8

In Canada, general requirements applicable to this Standard are provided in CAN/CSA-C22.2 No. 0.

This part of this European Standard defines the general requirements for wire intended for mechanical steel ropes. Additional requirements are given in the following parts of this European Standard, which are specific to each category of wire.

This part of this European Standard specifies:

  • dimensional tolerances;

  • mechanical characteristics;

  • requirements relating to the chemical composition of the steel wire;

  • conditions to be satisfied by any coating.

This European Standard is to be used together with EN 13001‑1 and EN 13001‑2 and as such they specify general conditions, requirements and methods to prevent mechanical hazards of wire ropes of cranes by design and theoretical verification.

NOTE

Specific requirements for particular types of cranes are given in the appropriate European Standard for the particular crane type.

The following is a list of significant hazardous situations and hazardous events that could result in risks to persons during intended use and reasonably foreseeable misuse. Clauses 5 to 6 of this standard are necessary to reduce or eliminate risks associated with the following hazard:

  • exceeding the limits of strength (yield, ultimate, fatigue).

This European Standard is not applicable to cranes which are manufactured before the date of its publication as EN and serves as reference base for the European Standards for particular crane types (see Annex C).

EN 13001‑3‑2 deals only with the limit state method in accordance with EN 13001‑1 .
