Calculate cable tray fill ratio, weight loading, and derating factors for multi-standard compliance. This calculator features an interactive interface with advanced visualizations. Using 3/4" conduit for each cable at. 27/ea into the box for. Determine the total usable cross-sectional area of the cable tray by multiplying its width by its height (or depth). For mixed cables, sum the areas of all individual cables. Determinate conduit size, fill percentage, pulling tensions, cable sidewall pressure, and jam probability with the new Re 3TM Cable Pull Calculator.
