Applies to mixed supply track systems for connecting both class I and class III luminaires simultaneously, but in different track openings to the electrical supply, with two or more poles with a maximum nominal voltage of 440 V between poles (live conductors), maximum nominal frequency of 60 Hz and a maximum nominal current per conductor of 16 A for a class I sector and 25 A for a class III sector. Applies to track systems designed for ordinary interior use for mounting on, 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.
