To ensure your cable tray system operates securely and complies with NEC standards, grounding and bonding are essential steps to follow. 96, even if the tray isn't being used as an equipment grounding conductor. Cable tray may be used as the Equipment Grounding Conductor (EGC) in any installation where qualified persons will service the installed cable tray system. This provides a safe path for any stray electrical currents to flow safely into the earth, avoiding damage to your equipment and reducing the risk of electric shocks. The intent of this article is to review grounding practices for cable tray.
[pdf] Verify weight capacity — Calculate the total cable weight per metre and confirm it does not exceed the tray's rated load capacity. Include allowance for future cables, typically 25% spare capacity for cable management. Material: Steel trays have a higher weight capacity than aluminium or plastic trays. Armoured cables. Load capacity is not just about how much weight the tray can physically support; it also involves maintaining proper fill percentages, ensuring adequate airflow, preventing ampacity derating, and preserving electrical safety through proper grounding and bonding. Ensure NEC compliance, estimate wire length/weight, calculate deflection, and generate hardware BOMs for bends, tees, and reducers.
