Description

Preface This is the first edition of CSA C22.2 No. 356, Cables for use in fault-managed power systems . This Standard applies to indoor, outdoor, or direct-buried Class 4 cables of Types FM4, FM4P, FM4R, and FM4Z, and rated 450 V peak with a temperature rating of 60 °C to 250 °C for use in fault-managed power systems. These cables may be installed in ordinary, dry, and wet locations, and in plenums and risers, in accordance with the Canadian Electrical Code, Part I. 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 Cables for Fault-Managed Power Systems, 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 Inclusions This Standard applies to indoor, outdoor, or direct-buried Class 4 cables of Types FM4, FM4P, FM4R, and FM4Z, and rated 450 V peak with a temperature rating of 60 °C to 250 °C for use in fault-managed power systems. These cables may be installed in ordinary, dry, and wet locations, and in plenums and risers, in accordance with the Canadian Electrical Code, Part I. This Standard is intended to be used in conjunction with CSA C22.2 No. 0.24. Note: The rated voltages of these cables are not marked. 1.2 Exclusions This Standard does not apply to general requirements for fault-managed power systems, which can be found in CSA C22.2 No. 0.24. 1.3 Terminology 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. 1.4 Units of measurement The values given in SI units are the units of record for the purposes of this Standard. Except for conductor sizes, the values given in parentheses are for information and comparison only.
