A Guide to Installing and Supporting Electrical Cable Trays
A professional guide to installing electrical cable tray systems per NEC Article 392. Covers support, securing cables, and fill calculations.
Answer: Yes; cables are tied down in cable trays to keep the cables in the cable tray, to maintain spacing between cables, or to segregate or confine certain types of cables to specific locations. The last two items can also be accomplished with a solid fixed barrier. Cable tray systems provide a safe, organized, and flexible method for supporting insulated conductors and cables in commercial and industrial electrical installations. When properly selected and installed, cable trays simplify routing, improve accessibility, and support future expansion while. A cable tray is an organized support structure designed to secure and route these insulated electrical cables. A cable tray system forms...
