Cable Tray Fill Calculator

To calculate the fill ratio, divide the sum of the cross-sectional areas of all cables by the total usable cross-sectional area of the cable tray. Multiply the result by 100 to express it as a percentage.

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.
