CSA C22.2 No. 14-2013

     

C22.2 NO. 14-13 - Industrial control equipment

Preface

This is the twelfth 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 2010, 2005, 1995, 1991, 1987, 1985, 1973, 1966, 1953, 1942, and 1935.

This edition incorporates numerous revisions. The major revisions include adding requirements for Type F combination motor controllers by making changes to the text and tables, adding Annex D for pressure sensitive floor mats and the addition of numerous clauses and Table 55 to outline the requirements for reduced spacings. Numerous other changes to various clauses and figures have been added to clarify or update specific requirements. Secondly, some changes were made to align the requirements of this edition with the requirements in CANENA-developed trinational documents that are based on the IEC 60947 series of Standards and are being adopted by Canada.

For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of CAN/CSA-C22.2 No. 0.

This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.

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 circuit switches 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; may is used to express an option or that which is permissible within the limits of the standard; and can is used to express possibility or capabili
