Description

Preface This is the second edition of CSA C22.2 No. 250.570, Track lighting , one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. It supersedes the previous edition published in 2016. The following are the major changes to this edition: a) simplification and clarification of the Scope (see Clause 1.1); b) revisions for movable joints containing conductors (see Clause 5.12); c) revisions for track adaptors (see Clauses 6.101.6, 17.105.2, 17.105.3, and 17.105.4); d) clarification of track lengths for canopies (see Clauses 6.103.1 and 6.103.2); e) clarification for indoor use only and track luminaires with fluorescent ballasts or metal halide lamps (see Clauses 8, 8.2.1, 9, and 9.3.6); f) removal of duplicate track clip test (see Clauses 17.102 and AA.5.7.2); g) clarification of tests for connectors and end covers, and preserving definitions (see Clauses 17.106, 17.108, 17.110, and 18.101.1); h) additions in accordance with CSA C22.2 No. 250 (see Clauses 6.20 and 10, and Annexes H, J, and K); and i) clause reference renumbering in accordance with CSA C22.2 No. 250.0. This Standard contains specific requirements for track lighting and is intended to be used together with the requirements for luminaires in CSA C22.2 No. 250.0. For general information on the Standards of the Canadian Electrical Code, Part II, see the Preface to CSA C22.2 No. 0. 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 Lighting Products, under the jurisdiction of the Technical Committee on Consumer and Commercial 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 Inclusions The requirements specified in this Standard apply to wall and ceiling-mounted track lighting systems intended to be installed in non-hazardous dry locations in accordance with the Canadian Electrical Code, Part I. These requirements apply to a) permanently installed track systems i) rated 347 V or less, 40 A max; ii) supplied by a power source with an output of 30 Vrms, 42.4 Vpeak, or 60 Vdc, and less than 240 VA; or iii) supplied by a Class 2 power source; b) permanently installed lighting systems employing bare conductors supplied by a power source with an output up to 30 Vrms, 42.4 Vpeak, or 60 Vdc, and less than 240 VA; c) extra-low-voltage suspended ceiling grid systems that operate up to 30 Vrms or 42.4 Vpeak, connected to a Class 2 power source; d) luminaire assemblies incorporating incandescent, fluorescent, light-emitting diodes, and high-intensity discharge lighting sources; and e) canopies and other accessories. Note: See Rule 30-104 of the Canadian Electrical Code, Part I, for the maximum rating of overcurrent protection. 1.2 Dual measurements The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only. 1.3 Terminology 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.
