Cable tray wiring systems offer significant advantages over conduit pipe and other wiring systems. It is less expensive, more reliable, more adaptable to changing needs and easier to maintain. In addition, its design does not contribute to potential safety problems associated with other wiring systems.

Extensive experience has shown that the initial cost of a cable tray installation (including conductor, material and installation labor costs) may be as much as 60% less than a comparable conduit wiring system. Cable tray systems, including trays, supports, fittings and other materials, are generally much less expensive than conduit wiring systems.
