When a cable tray changes direction, such as in a horizontal elbow or vertical rise/drop, the inner rail of the bend becomes more crowded than a straight section. This means that even if the tray width is sufficient for a straight run, the bend may reduce usable space, potentially pinching cables if not properly sized or planned . Wider trays with small centerline radii are particularly prone to inner-cable crowding .
The bend width of a cable tray is not simply the tray's nominal width; it must consider the inner radius, cable diameters, fill limits, and tray type. Proper planning ensures safe cable installation, prevents overheating, and allows for future expansion .
