PrefaceThis is the third edition of CSA C22.2 No. 159 Plugs, connectors, receptacles, and similar wiring devices for use in hazardous locations. It supersedes the previous editions published in 1987 and 1982 under the title Attachment plugs, receptacles, and similar wiring devices for use in hazardous locations. Changes to this edition include the a) addition of Division 2 and Class III; b) removal of requirements covered by other standards; and c) addition of Annex A to indicate how C22.2 No. 182.1 and C22.2 No. 182.3 are applied for the products covered by this Standard.Scope1.1 This Standard covers receptacles with attachment plugs; receptacles with attachment plugs interlocked with circuit breakers; receptacles with attachment plugs interlocked with switches; and cable and cord connectors, couplers, and flanged equipment power inlets and flanged equipment power outlets with ratings as specified in Clause 1.2 intended for connection to copper conductors only and for installation and use in the following hazardous locations in accordance with the Rules of Canadian Electrical Code, Part I and CSA M421: a) Class I, Division 1, Groups A, B, C, and D; b) Class I, Division 2, Groups A, B, C, and D; c) Class II, Groups F and G; and d) Class III. 1.2 This Standard covers a) Class I, Division 1 and Class II devices rated not more than 600 A or not more than 600 V ac or not more than 250 V dc; b) Class I, Division 2 devices rated not more than 1200 A and not more than 1000 V ac or not more than 1000 V dc; and c) equipment for gaseous mines rated not more than 1100 V ac. 1.3 This Standard does not cover plug and receptacle/connector combinations that do not incorporate either a delayed withdrawal, an interlock mechanism or other retaining device. Note: In this Standard, devices that are classified for Group G locations are acceptable for use in atmospheres containing coal or coke dust. 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.
