This is the fourth edition of CSA C22.2 No. 96.1, Mine power feeder cables, one of a series of Standards issued by CSA Group under the Canadian Electrical Code, Part II. It supersedes the previous editions, published in 2013, 2009, and 2004.
In this edition, the testing procedures have been changed as a result of CSA C22.2 No. 03 being replaced by CSA C22.2 No. 2556. Ampacity values in Annex D have also been changed to align with the international industry requirements.
This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.
This Standard was prepared by the Subcommittee on Portable and Mine Power Cables, under the jurisdiction of the Technical Committee on Wiring Products and the Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the 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.
This Standard specifies construction and testing requirements for unarmoured mine power feeder cables normally used for power distribution in stationary or semi-stationary applications covered by CSA M421 and the Canadian Electrical Code, Part I.
