CAN/CSA-E570-98 (R2017)

This National Standard of Canada is based on International Standard IEC 570:1995. 1 Scope This standard applies to track systems with two or more poles for the connection of luminaires to the electrical supply, either of rated voltage not exceeding 440 V between poles with provision for earthing (class I) and a rated current not exceeding 16 A per conductor, or of a rated SELV not exceeding 25 v without provision for earthing (class III) and rated current not exceeding 25 a per conductor. The track systems may also provide for the mechanical support of the luminaires. It applies to track systems designed for ordinary interior use for mounting on, or flush with, or suspended from walls and ceilings. These track systems are not intended for locations where special conditions prevail as in ships, vehicles and the like and in hazardous locations, for example, where explosions are liable to occur. This standard shall be read in conjunction with the sections of IEC 598-1 to which reference is made.
