Formula variables
- Tray width and usable depth are entered in millimetres.
- Cable area is the entered area for one cable.
- Cable count is the number of similar cables in the tray screen.
- Fill target is a user-entered planning value for comparison.
Assumptions
- The tray area is calculated from entered width and usable depth.
- Cable area and count are entered by the user from product or layout data.
- The fill target is entered by the user and is not set by this calculator.
- This calculator does not set cable tray fill limits, cable spacing, support loading, grounding, bonding, or installation acceptance.
Examples
Basket tray screen. A 300 mm by 50 mm usable area with forty 95 mm2 cables estimates 25.33 percent occupied area.
Catalogue workflow. Use manufacturer tray data, spacing, loading, and support requirements before using the screen for layout decisions.
