Preface

This is the eleventh edition of CSA C22.2 No. 14, Industrial control equipment, one of a series of Standards issued by the Canadian Standards Association under Part II of the Canadian Electrical Code. It supersedes the previous editions, published in 2005, 1995, 1991, 1987, 1985, 1973, 1966, 1953, 1942, and 1935.

Scope

1.1
This Standard applies to control and protective devices, and accessory devices, rated at not more than 1500 V, for starting, stopping, regulating, controlling, or protecting electric motors, generators, heating apparatus, or other equipment used to control an industrial process that is intended to be installed and used in non-hazardous locations in accordance with the rules of the Canadian Electrical Code, Part I.Notes:
(1) Examples of the industrial control devices covered by this Standard are manual and magnetic starters and controllers;thermal and magnetic overload relays; push-button stations (including selector switches and pilot lights); control circuitswitches and relays; float-, flow-, pressure-, and vacuum-operated switches; resistors and rheostats; proximity switches; time-delay relays and switches; resistors and rheostats intended for heating and lighting, including those for motor generator fields; and control devices intended for heating and lighting.
(2) The term “control” as used throughout this Standard applies to both starters and controllers.
(3) Electrical instruments, such as meters, that can be included as part of control equipment are not covered by this Standard.

1.2
This Standard also applies to assemblies of industrial control and protective devices rated 750 V or less, and includes assemblies of automatic control and process equipment.

1.3
Certain equipment intended for use with electric elevators, air-conditioning and refrigeration equipment, cranes and hoists, electronic and solid-state control equipment, and “TV”-rated relays, etc., can be subject to additional requirements not included in this Standard.

1.4
This Standard does not apply to equipment covered by other CSA Standards, such as power supplies, programmable logic controllers, assemblies of equipment intended solely for the distribution of power, assemblies for controlling power factor, switches other than manual motor controllers, and electrical components intended to protect circuits other than motor branch-circuits.

1.5
The industrial control equipment covered by this Standard is intended for use in an ambient temperature of 0 to 40 °C.

1.6
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. 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.
