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. At least 12 inches of clear space should be provided between tray. 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. us-trations without notice. 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. When developing our cable support OBO can offer reliable solutions for systems, three attributes are at the routing and fastening cables securely core of what we do: efficiency, resil- for each of these installation challeng-ience and safety. es in the industrial environment. This. In this guide, you will learn how to calculate cable tray size step by step using a practical formula, tray selection rules, and a real example.
