How to connect a flexible cable tray
Use the recommended quantity of UL Classified splices to connect sections and at places where the tray is cut. Run an appropriately sized ground wire alongside the tray and attach it to each tray section and on both sides of a cut in the tray. To properly bond Hubbell ® painted cable tray, remove the plastic masking device from the trays on each end (exposing the pre-galvanized wire), and splice sections. The FlextrayTM system is a flexible, field-adaptable way to manage cables throughout your project. The tray can be cut and bent to the needs of the installer on the jobsite, allowing cable runs to be adjusted as needed. and requires no additional bonding or jumpers for UL compliance. Most common is the Splice Kit and Double splice. It covers the most common components used in a fiber tray installation, but each installation is different and the unique circumstances and requirements of any given installation environme qualified technicians.
