Cable tray separation | Automation & Control Engineering Forum
Trays for cables of different voltage levels should be stacked in descending order with the higher voltage. Instrumentation trays should always be at the bottom.

A good rule of thumb from DOE critical installations is: Trays for cables of different voltage levels should be stacked in descending order with the higher voltage. All illustrations, descriptions and technical information included in this document are provided as indications and can cable trays are equivalent. The mechanical and electrical characteristics, tests, certifications, overall quality management, recommendations mentioned. in this document have been tested extens ompetent professional en completely installed, without damage either to conductors orstructural system use 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. In instrumentation EPC (Engineering, Procurement, and Construction) projects, installing cable trays is very important for making sure that signals are sent reliably, that people are safe, and that systems work well for a long time. low level instruments on one side of a tray with a metallic divider then 120VAC on the other side of the same tray) sometimes power can be in the same tray.
