Preface

This is the third edition of CSA C22.2 No. 286, Industrial control panels and assemblies , one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. It supersedes the previous editions published in 2017 and 2015. The major changes to this edition include a) expansion of requirements for connection means; b) additional requirements for ferrules and pigtail adapters; c) clarifications for requirements for Class 2 (non-safety control devices) components; d) additional compliance criteria for panels and assemblies for use outside of the assumed 0?40° C ambient range; e) expansion of the short-circuit current rating (SCCR) determination criteria; f) revisions to required SCCR markings; g) removal of motor control centre requirements; and h) addition of strain relief and abnormal operations tests. In addition, numerous edits have been performed throughout the document to provide additional information and clarify certain requirements. For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of CSA C22.2 No. 0, General Requirements ? Canadian Electrical Code, Part II. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was prepared by the Integrated Committee on Industrial Control 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. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Scope

1.1 This Standard applies to industrial control panels and assemblies rated at not more than 1500 V, 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 industrial control panels and assemblies covered by this Standard include motor control panels, process control equipment panels, heating panels, programmable control panels, heating and cooling equipment control panels, etc. 2) The term ?control? as used throughout this Standard applies to both starters and controllers. 3) Electrical instruments that can be included as part of control equipment such as meters, are not covered by this Standard.

1.2 The industrial control panels and assemblies covered by this Standard are intended for use in an ambient temperature of 0 to 40 °C. Additional investigation of the equipment will be required when equipment is to be used in an ambient temperature outside of this range.

1.3 This Standard does not apply to equipment covered by other CSA Standards, such as but not limited to a) power supplies; b) automatic transfer switches; c) elevator equipment; d) enclosed switches; e) switchgear; f) line isolation monitors; g) panelboards and custom panelboards; h) hazardous location equipment; i) hydro-massage equipment; j) power factor correction capacitor banks; k) fire pump controllers; l) assemblies of equipment intended solely for the distribution of power; and m) motor control centre units and sections.

1.4 This Standard does not apply to external loads controlled by the industrial control panels and assemblies.

1.5 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 (non-mandatory) to define their application.
