Preface<\/strong><\/p>\n

<\/p>\n

This is the first edition of CSA C22.2 No. 0.22, Evaluation methods for arc resistance ratings of enclosed electrical equipment<\/em>, one of a series of Standards issued by the Canadian Standards Association under Part II of the Canadian Electrical Code.<\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

Scope<\/strong><\/p>\n

<\/p>\n

1.1<\/p>\n

This Standard establishes methods by which metal-enclosed equipment can be tested for resistance to the effects of arcing resulting from an internal fault.<\/p>\n

<\/p>\n

1.2<\/p>\n

This Standard applies only to indoor and outdoor equipment that uses air as the primary insulating medium and that is rated up to 46 kV ac.<\/p>\n

<\/p>\n

Note: Building size and construction are factors to be considered in indoor applications. These factors are not addressed in this Standard.<\/p>\n

<\/p>\n

1.3<\/p>\n

The tests and assessments described in this Standard are applicable only to arcing faults occurring entirely in air within the enclosure when all doors and covers are properly secured.<\/p>\n

<\/p>\n

1.4<\/p>\n

This Standard does not apply to arcing faults that occur within a component of the assembly, such as instrument transformers, sealed interrupting devices, or fuses.<\/p>\n

<\/p>\n

1.5<\/p>\n

Metal-enclosed switchgear designs that meet the requirements of this Standard are referred to as arc-resistant switchgear. Motor control designs that meet the requirements of this Standard are referred to as arc-resistant motor control.<\/p>\n

<\/p>\n

Note: Annex C provides additional information on the consequences of internal arc faults, equipment qualified to this Standard, relevance of tests, and the application of this Standard.<\/p>\n

<\/p>\n

1.6<\/p>\n

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.<\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

Notes to tables and figures are considered part of the table or figure and may be written as requirements.<\/p>\n

<\/p>\n

Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.<\/p>\n

<\/p>\n

1.7<\/p>\n

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.<\/p>\n","protected":false},"excerpt":{"rendered":"
