• connected to a branch circuit not rated more than 300 volts and not more than 50 amperes; or
• connected to a remotely located power source rated not more than 30 Vac or 60 Vdc and not more than 25 amperes.

These requirements cover:

• Track networks consisting of track and connectors;
• Mono-, duo-, and multi-point canopies;
• Incandescent, fluorescent, and high-intensity discharge (HID), and LED luminaire assemblies intended to be electrically connected to and physically supported by the track in track networks and canopies;
• Mounting means for the track; and
• Accessories.

These requirements do not cover:

A track lighting luminaire assembly that uses a tungsten-halogen lamp, fluorescent lamp, high-intensity-discharge, or LED lamp shall also comply with:

• The applicable requirements from the Standard for Luminaires, UL 1598, if rated more than 30 Vac or 60 Vdc; or
• The applicable requirements from the Standard for Low Voltage Lighting Systems, UL 2108, if rated 30 Vac or 60 Vdc or less.

Light emitting diode (LED) components and subassemblies integral to lighting track or a luminaire assembly covered by this standard shall comply with the applicable requirements of the Standard for Light Emitting Diode (LED) Equipment for Use in Lighting Products, UL 8750.
