ICS Code (29.120.60): 29.120.60
scope:

This Standard applies to deadfront indoor enclosed and outdoor enclosed assemblies of switchgear devices such as

a) switches;

b) interrupting devices;

c) air circuit breakers;

d) power circuit breakers; and

e) control, metering, protective, and regulating equipment with associated interconnections and supporting structures.

This Standard covers equipment with a nominal voltage of 46 kV or less that is intended to be used

a) in accordance with the Canadian Electrical Code, Part I;

b) in non-hazardous locations;

c) for controlling and protecting the power from generators or other sources; and

d) for supplying electrical energy to power and lighting circuits.

This Standard does not apply to panelboards, industrial control equipment, switchboards for communication circuits (see the Canadian Electrical Code, Part I), or low-voltage assemblies consisting of separately supported enclosed switches, enclosed circuit breakers, and possibly service meters, with interconnection between them enclosed in raceways.

Note: Manufacturers and installers of switchgear assemblies approved under this Standard should take due note of the Canadian Electrical Code, Part I, with respect to the location of switchgear devices in areas where certain components might not be acceptable.

Clauses 2 to 6 apply to all switchgear assemblies and are supplemented and amended by

a) Clause 7 for low-voltage switchgear assemblies; and

b) Clause 8 for high-voltage switchgear assemblies.

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 (nonmandatory) to define their application.
