Scope:

Note: The scope for this NOI (originally published on November 22, 2022) were updated by the responsible SDO on February 27, 2024.

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 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.

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.

Project need:

In Canada there is a need to define best practices for maintenance of industrial, institutional, and commercial electrical systems and power supplies to ensure personnel safety, loss prevention and optimizing the operability of critical equipment. There are stringent industry standards in the design, manufacture and installation of electrical equipment and systems. It is equally important to maintain that equipment to the design, manufacture and installation in its original condition. Equipment's "condition of maintenance" has become a key element in the risk assessment process in CSA Z462-21 (with many corresponding references to Z463). Revision of the Z463-18 standard is needed to incorporate new technologies, streamline the current content and use the 2023 revision as an opportunity to refine the standard. 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 practice and it is intended to address worker and public safety as a primary objective and the protection of property and the environment as secondary objectives
