The 277V Two Circuit/Two Neutral Track Lengths system is well suited for larger retail and institutional applications where a number of metal halide or fluorescent features will be used. This system offers twice the capacity of 120V track length systems, and multiple breaker sizes are available and can be mounted to most surfaces. This track length is for use with non-track linear multi-head products, and is engineered to be a durable, dependable and simple-to-install lighting solution. An integral suspension rail and pre-drilling mounting holes of the track are factory shopping and simplify installations. Track sections are available in white, black and aluminum finish.
