Optical network knowledge brief Published 26 Oct 2023

Prepared for preliminary research by the COETZER OPTICAL knowledge desk. Confirm compatibility, loss budgets and installation requirements against current standards and product documentation.

All metallic cable trays shall be grounded as required in Article 250. The EGC is the most important conductor in an electrical system as its function is electrical safety. Here's what you need to know: Cable Types: Only use. NEC Article 392 governs cable tray systems. Grounding and bonding are mandatory for metallic trays. The metal in cable trays may be used as the EGC as per the limitations. maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system.
