CAN/CSA-C22.2 NO. 14-05
Industrial control equipment
Product Details
Preface
This is the tenth edition of 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 1995, 1991, 1987, 1985, 1973, 1966, 1953, 1942, and 1935.
This Standard incorporates requirements from TIL 6D, TIL D17, TIL D24, TIL D23A, Bulletin 933, and the Guideline on Intrinsic Safety Barriers. Other significant changes include the addition of requirements for fire pump controllers, capacitor switching ratings, group connected relays and controllers, and pass/fail criteria for contacts and solid-state devices.
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 was prepared by the Subcommittee on C22.2 No. 14, under the jurisdiction of the Technical Committee on Industrial Products and the Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee.
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, and includes motor control centres and 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.
