CSA C22.2 NO. 123:26

Description

Preface This is the seventh 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 2016, 2008, 1996, 1985, 1964, and 1962 under the title Aluminum Sheathed Cables. This edition of CSA C22.2 No. 123 includes the following key changes: a) updating the requirements on conductor shielding in Clause 4.1.4 and adding a new Table 16; b) updating the requirements for length of lay in Clause 4.5.2 and Table 5; c) updating Clause 4.6.3.1 and Tables 6 and 7 to refer to a new Table 4 for minimum size conductors for bonding conductors; d) updating Table 9 to remove grey colour coding of circuit conductors; and e) updating the physical properties for thermoplastic and thermoset jackets in Tables 11, 14, and 15 to align with the requirements in CSA C22.2 No. 131. 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 ICWC03-Metal Clad 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. 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 CSA C22.1, 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; and “may” is used to express an option or that which is permissible within the limits of the standard. 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.
