The UL Classified Cable Runway (also called ladder rack) can be used in any standard cable runway application.
The National Electric Code (NFPA 70), however, requires the use of UL Classified Cable Runway when it is adopted as an equipment grounding conductor, such as when racks are bonded to the cable runway instead of running an individual ground conductor from the Telecommunications Grounding Bus Bar to each rack.
The UL Classified Cable Runway is a Telco-style, 9’ 8-1/2” long cable runway (ladder rack) with a gold or black chem film over zinc plating. Because UL Classified Cable Runway is zinc plated, it can be bonded together using UL Classified Splices, without the need for ground straps. Installation is therefore, quick and easy.
