Preface
This is the fifth edition of CSA C22.2 No. 123, Metal sheathed cables. It is part of a series of Standards issued by the Canadian Standards Association under Part II of the Canadian Electrical Code. It supersedes the previous editions published in 1996, 1985, 1964, and 1962 under the title Aluminum Sheathed Cables.
1 Scope
1.1
This Standard applies to single-conductor and multi-conductor Type RA90 and RC90 cables having a maximum temperature rating of 90 °C in both dry and wet locations and intended for installation in accordance with the Rules of the Canadian Electrical Code, Part I.
1.2
Cables covered in this Standard are intended for use on systems having nominal voltages up to 5000 V, except for 2-conductor, parallel, smooth aluminum sheathed cable, which is limited to 600 V.
1.3
Type RA90 aluminum or RC90 copper sheathed cables covered by this Standard consist of a seamless, smooth metal sheath or seamed or seamless, corrugated metal sheath applied over one or more insulated conductors. In some cases an optional nonmetallic overall covering is applied over the sheath.
1.4
In CSA Standards, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the standard; and “can” is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
