How to calculate the fill degree of cable trays

Home / How to calculate the fill degree of cable trays

Size the tray by calculating total cable cross-sectional area and dividing by the allowable fill percentage (typically 40%). Our free calculator helps you determine the correct tray size based on NEC and IEC standards. Follow these simple steps: Define Tray Dimensions: Enter the width and depth of your planned cable tray (in mm or inches). NEC Article 392 limits fill ratios based on cable type and arrangement — single-layer or stacked — to ensure adequate ventilation, maintain current-carrying capacity, and provide space.
