Cable Tray Fill Calculator

This tool streamlines cable tray fill analysis and design compliance to IEEE Std 525 (2023) and substation guidelines, calculating fill percentage from total cable versus usable tray area and checking against recommended limits. It reports compliance and suggests design changes—such as wider trays, modified tiers, or improved segregation—to ensure safe, maintainable, code-aligned tray installations.
