Right Sizing Your Pathways—From Tray to Conduit
Per the NEC, the actual maximum fill ratio of any cable tray is 50%. TIA recommends a maximum 40% fill ratio based on the cross-sectional area of the cable and the tray area (width X depth).
Application Note
For Cable Trays, the recommendation is to design for (and install) at no more than a 25% cable fill ratio (the cable tray at a 25% fill ratio will look half full).
