1.1 Inclusions

This standard applies to indoor, outdoor or direct buried cable types FM4, FM4P, FM4R and FM4Z, rated 450V peak with a temperature rating of 60 ⁰C to 250 ⁰C for use in Fault Managed Power Systems (FMPS). These cables may be installed in ordinary, dry and wet locations, in plenums and risers in accordance with the Canadian Electrical Code, CE Code Part I.

This standard shall be used in conjunction with CSA C22.2 No. 0.24, General Requirements for Fault-Managed Power Systems (FMPS).

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 (FMPS), which are covered in CSA C22.2 No. 0.24, General Requirements for Fault-Managed Power Systems (FMPS).

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 measure

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only. Except for conductor sizes, the equivalent "inch/pound" values are in parentheses.
