Flextray load and fill recommendations
Cables will nearly completely fill the cable tray when reaching the 50% cable fill, due to empty space between the surface of the cables. TIA recommends 40% fill ratio. Flextray loads shown in the
Cable Tray Fill Rules (NEC 392)
A cable rated at 65A in a single conduit run drops to 32.5A when packed in a full cable tray. This derating can force you to use a wider tray, add a second tray, or increase conductor sizes.
