Preface: This is the first edition of CSA/ANSI C22.2 No. 184.2, Solid-state controls for lighting systems (SSCLS). It is one of a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. 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 Wiring Devices, under the jurisdiction of the Technical Committee on Wiring 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. This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Scope: 1.1 This Standard applies to permanently connected, single or multi-branch circuit, multi-circuit output, solid-state lighting controls rated at 600 V and less, 50 or 60 Hz; single or three phase; with or without overcurrent protection on the load side; with or without integral load switching devices; designed to be used as a complete solid-state lighting control system for the purpose of controlling a single type or multiple types of lighting loads, such as a) incandescent lamps; b) magnetic ballasts; c) fluorescent, compact fluorescent, and electric discharge lamps; d) HID (pilot duty) and electronic ballasts; e) LED and OLED lights and drivers; and f) 0 to 10 V dc analog dimming and intended for installation in accordance with CSA C22.1, Canadian Electrical Code, Part I, and NFPA 70, National Electrical Code (NEC). 1.2 This Standard also applies to SSCLS products mounted in a portable manner. Note: "Mounted on wheels" can include wheel-mounted equipment that can be moved by one person, up to large truck- or trailer-mounted assemblies. Similarly, "mounted on skids" can include equipment that is small enough and light enough to be moved by one person, up to large or heavy units that can only be skidded with larger towing vehicles or lifted and moved with hoists or cranes. 1.3 This Standard applies to ac rated controls for which the load rating does not exceed 40 A per circuit at a maximum of 600 V. 1.4 SSCLS products may include receptacles of configuration 5-15R, 5-20R, and L5-20R, used as lighting load connection points, with access limited to qualified personnel only. 1.5 SSCLS products may include convenience receptacles, mechanical switches, dimming circuits, and other wiring devices on separate circuits. 1.6 SSCLS products may include NC (normally closed) or NO (normally open) contacts for the purpose of controlling other general-use loads rated inductive, resistive, and 2 hp or less. 1.7 SSCLS products may include a Class 2 power supply for the purpose of feeding power to analog or digital inputs, such as sensors. 1.8 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. 1.9 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.
