Preface:

This is the thirteenth edition of CSA C22.2 No. 51, Armoured 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 2014, 2009, 1995, 1989, 1981, 1968, 1961, 1957, 1953, 1949, 1941, and 1938.

The main changes to this edition include the following:

• reduction of the minimum conductors size from 14 to 18 AWG;
• introduction of the “-PCS” suffix indicating a construction, including control and signal insulated copper conductors;
• in Clause 7.1.2, tape markers or jacket printing may be substituted for the indented and embossed markings;
• addition of optional halogen-free marking in Clause 7.1.2; and
• addition of Tables 22 and 23 and Figure 5.

For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of CSA C22.2 No. 0.

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 specifies requirements for single- and multi-conductor insulated cables having metallic interlocked armour without an overall jacket (Type AC90 or ACG90) or with an overall jacket (Type ACWU90 or ACGWU90) that are intended for installation in accordance with CSA C22.1, Canadian Electrical Code, Part I, on systems having nominal voltages of 2000 V and less. ACG90 and ACGWU90 apply to multi-conductor cables only. ACG90 and ACGWU90 shall have voltages of 600 V and less.

1.2
This Standard specifies requirements for cables having insulated conductors in sizes 18 AWG to 2000 kcmil. The maximum cable temperature rating is 90 °C.
Note: See Annex B for a summary of the cable types covered by this Standard and corresponding constructions, voltage ratings, and the number and size of conductors for the types to which this Standard applies.

1.3
In this Standard, “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.
