CAN/CSA-E920-98 (R2017

This National Standard of Canada is based on International Standard CEI/IEC 920:1990 1. Scope This standard covers ballasts, excluding resistance types, for use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz, associated with tubular fluorescent lamps with or without pre-heated cathodes operated with or without a starter or starting device and having rated wattages, dimensions and characteristics as specified in IEC Publication 81 or ANSI C78.1-91, Fluorescent lamps - rapid start types - dimensional and electrical characteristics; ANSI C78.2-91, Fluorescent lamps - pre-heat start types - dimensional and electrical characteristics; ANSI C78.3-91, Fluorescent lamps - instant-start and cold-cathode types - dimensional and electrical characteristics; and ANSi C78.4-95, Fluorescent lamps - self-supporting single based compact types - dimensional and eletrical characteristics. It applies to complete ballasts and to their component parts such as reactors, transformers and capacitors. Particular requirements for thermally protected ballasts are given in Appendix B. This standard also specifies ballasts for lamps which are not yet fully standardized. Ballasts for conventional operation of lamps at mains frequency are covered. A.C. supplied electronic ballasts for high frequency operation are excluded. These are specified in IEC Publication 928. Capacitors having a capacitance greater than 0.1 µF are covered by IEc Publication 566. Capacitors having a capacitance less than or equal to 0.1 µf are specified in IEC Publication 384-14. This Standard applies to the safety of such equipment designed to be installed on branch circuits not exceeding 750 V and used in accordance with the rules of the Canadian Electrical Code, Part I. Note: Manufacturers designing products for use in Canada may find a helpful summary of the equipment-related requirements of the Canadian Electrical Code, Part I, in CSA Publication SPE-2000. Note: IEC Publication 901 covers performance and safety requirements for single capped fluorescent lamps.
