What size should the horizontal cable tray support be

For horizontal sections where cable trays are laid out in a straight line, the typical support span (distance between supports) should range from 1. This range allows for easy access and efficient maintenance. Hanging rod supports should be at least 8mm in diameter. Ensures vertical. Although BS 7671 touches on the subject of cable supports, it does not detail specifically what these support distances should be. 8 (Other Mechanical Stresses (AJ)) in that document provides requirements for cable support. The cable tray support span must be determined based on the manufacturer's load capacity chart and the total anticipated weight of the cables. Support Methods: Common support methods include trapeze hangers, which are. 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.
