Cable tray hanger width is typically selected to match or slightly exceed the nominal inside width of the cable tray, ensuring proper support and stability.
Cable trays come in standard nominal inside widths ranging from small control circuits to large power or solar DC trunk runs. Common widths include 100mm, 150mm, 200mm, 300mm, 400mm, 500mm, and 600mm, with the outside width slightly larger due to side rail thickness . The tray width determines cable capacity, airflow, and ease of installation, and it directly influences the required hanger width.
When designing or installing cable tray systems, always verify hanger width against the tray's outside dimensions, including side rail thickness, and consider future cable expansion. Using hangers that are too narrow can lead to tray deflection, cable damage, or non-compliance with electrical codes .
In summary, the cable tray hanger width is generally equal to or slightly greater than the tray's nominal inside width, adjusted for side rail thickness, load, and span requirements to ensure safe and code-compliant installation.
