Over Twice The Capacity Of Standard 120V Track- Allows Longer Track Runs With More Fixtures- Reduced Installation Costs- Fewer Feed Points and Home Runs- Ideal For HID Metal Halide and Compact Fluorescent Fixtures- Dimming feature available - see track luminaire for compatibility.- UL listed For Dry LocationsThe Intense Professional Series 2-cct/2-neutral 277V track system is well suited for larger retail and institutional applications where a number of HID Metal Halide or fluorescent fixtures are used. The 277V system offers twice the capacity of ordinary 120V track allowing for substantially longer runs with more fixtures between feed points. This translates into enhanced aesthetics and reduced installation costs. Fewer feed points mean fewer costly home runs to the panel box. The isolated neutrals mean that cross-circuit interference and neutral harmonics are completely eliminated, ensuring superior fixture performance and life. Independent neutrals also offer twice the power handling capacity of ordinary common neutral track.
