CSA Z463:24

1 Scope 1.1 General This Standard specifies requirements for the maintenance of electrical equipment and systems. This Standard applies to new and existing electrical equipment. For new installations of electrical equipment, this Standard can be applied during the early design stages to allow for the implementation of proactive electrical maintenance practices and maintenance safety. 1.2 Purpose The purpose of this Standard is to facilitate the safe, reliable, and cost-effective operation of electrical equipment and systems through the application of consistent maintenance practices. The requirements of this Standard are intended to address worker and public safety as a primary objective and the protection of property and the environment as secondary objectives. 1.3 Application This Standard does not apply to maintenance of electrical and communications supply equipment and systems owned by electric and communication utilities. These requirements are covered by CSA C22.3 No. 11. 1.4 Measurements 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. 1.5 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.
