C22.2 NO. 286-17

Preface This is the second edition of 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, Part I. It supersedes the previous edition published in 2015. This edition incorporates a new clause for electrical spacings and a new clause for testing requirements that addresses temperature, dielectric strength, and impact testing. Table 11 has been significantly expanded and new Tables 16 through 20 have been added. In addition, numerous edits have been performed throughout the document to provide additional information and to clarify certain requirements. For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface of CAN/CSA-C22.2 No. 0, General Requirements ? Canadian Electrical Code, Part II. 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 or modifications to equipment covered by other CSA Standards, such as: 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 sections. 1.4 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.
