This Standard applies to electric motors and generators for installation and use, in accordance with the Rules of the Canadian Electrical Code, Part I, in non-hazardous locations.

Note: The term "machine" throughout this Standard should be assumed to mean "motor" and "generator".

Clauses 2 to 7 are general in nature and apply, unless otherwise noted, to the motors and generators covered by Clauses 8 to 13 as follows:

a) Clause 8 - DC machines and AC machines (including universal motors) in IEC frame size 80 and smaller;

b) Clause 9 - AC machines (including universal motors) in IEC frame sizes 90 to 280 and rated 750 V ac and less;

c) Clause 10 - AC machines rated over 750 V ac or in IEC frame size 315 and larger;

d) Clause 11 - DC machines in IEC frame size 90 and larger;

e) Clause 12 - portable and standby generators; and

f) Clause 13 - inverter-duty AC machines.

This Standard provides basic requirements for machines and does not exclude any additional requirements given in other Standards of the Canadian Electrical Code, Part II.

This Standard does not apply to

a) sealed- (hermetic-) type motors such as those used in refrigerant compressors; or

b) electric machines for use in aircraft, marine service installations, drives for land transportation equipment, or machines used in underground mining.

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.
