Prior to installing cable in the cable tray, examine cable paths to ensure all areas are free of debris that may interfere with the cable''s installation. The cable tray should never be used as a walkway.
All trays must undergo salt spray tests and coating thickness tests to ensure the coatings meet the durability levels required under the IEC standard
A cable tray system is an assembly of metallic cable tray sections and accessories, that forms a rigid structural system to support cables.
If cable trays are sized for future cables, specify provisions for penetrations with sleeves through fire-rated partitions or use "repairable" firestop-sealing material.
This guide covers cable ladder systems, cable tray systems, channel support systems and associated supports intended for the support and accommodation of cables and possibly other electrical
