Preface

This is the sixth edition of CSA C22.2 No. 124, Mineral-insulated cable. It supersedes the previous editions published in 2004, 1986, 1974, 1966, and 1960. This Standard is issued by CSA Group under Part II of the Canadian Electrical Code.

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

This new edition includes the following changes:

a) the addition of

    i) requirements for thermoset materials;

    ii) requirements for nickel alloy-clad copper and steel-clad copper conductor materials;

    iii) a durability of print test for all ink-printed cables;

    iv) an optional FT6 flame test on constructions with overall covering; and

    v) an optional weather resistance test and related marking requirements; and

b) an increase in the range of conductor sizes covered.

Scope

1.1
This Standard applies to mineral-insulated cables with copper, nickel/nickel alloy-clad copper, steel-clad copper, or nickel conductors, enclosed in a copper or stainless steel sheath.

1.2
The constructions covered by this Standard are intended for use in power, instrumentation, control, and fire alarm systems that are intended to be installed in ordinary locations in accordance with CSA C22.1, Canadian Electrical Code, Part I.

1.3
The constructions covered by this Standard are recognized for use where normal conditions are such that no part of the cable is subjected to a temperature in excess of 250 °C. When provided with an overall thermoplastic or thermoset protective covering, the use is restricted to 90 °C.

1.4
The constructions covered by this Standard are

a) Type MI mineral-insulated, copper-sheathed cable recognized for use on systems having a nominal voltage of 600 V or less;

b) Type SSMI mineral-insulated, stainless steel-sheathed cable recognized for use on systems having a nominal voltage of 600 V or less;

c) Type LWMI mineral-insulated, copper-sheathed cable recognized for use on systems having a nominal voltage of 600 V or less; and

d) Type SSLWMI mineral-insulated, stainless steel-sheathed cable recognized for use on systems having a nominal voltage of 600 V or less.

1.5
Optional requirements are provided for

a) twisted pair configurations;

b) copper or stainless steel shields;

c) overall thermoplastic or thermoset protective coverings;

d) flame test classification; and

e) fire rating.

1.6
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 (nonmandatory) to define their application.
