This standard applies to the following rail systems including the use of two-pole or multi-pole conductors to connect luminaires to the power supply: - With grounding device (Class I), the rated current of each conductor does not exceed 16A, and the rated voltage between poles (live conductors) Rail systems not exceeding 440V, or - rail systems that do not provide grounding (category III), rated current per conductor not exceeding 25A, rated safety extra-low voltage not exceeding 25V, or - a combination of the above two rail systems, capable of connecting To mains-powered luminaires (Class I or II) and SELV-powered luminaires (Class III), but with different paths (mains or SELV). The rail system can provide mechanical support for the luminaire. This standard applies to rail systems designed for ordinary indoor use, where the rails are mounted on, embedded in, or suspended from walls and ceilings. These rail systems are not intended for use where special conditions are often present, such as ships, automobiles, etc., nor are they intended for use in harsh locations, such as hazardous areas where explosions may occur.
