Use edge protectors or trays with rolled edges to reduce abrasion. Industrial environments frequently require cable trays to support heavy cable bundles, sometimes alongside other equipment or accessories. Sagging and Deflection: Excessive bending occurs when trays carry loads beyond their designed capacity or when support intervals are improperly spaced. Misalignment and Joint Failures: Incorrect assembly of tray sections can lead to gaps, weak joints or uneven surfaces, causing stress. 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 ladders, cable trays and their supports should be strong enough to meet the load requirements of the cable management system including cables and any future cable additions and any other additional loads applied to the system. It is recommended that the work described be performed by a competent person(s) familiar with standard electrical installation. that system to lose its UL Classification. Recognizing and addressing these failures early can prevent more severe issues.
