Cable tray support quantity can be calculated using a simple formula: Support Quantity = Total Length ÷ Support Spacing + 1 20 ÷ 2 + 1 = 11 supports In a typical project, a 20-meter cable tray with 2-meter spacing requires 11 supports. 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). Additional engineering factors must be considered to ensure safety, reliability. The National Electrical Code (NEC) is the ultimate authority for any cable tray installation. Specifically, NEC Article 392 governs the use, installation, and construction specifications for these systems. 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.
