Ventilation engineering includes cable trays
Ventilation indicates the tray's ability to dissipate heat from cables. Open designs like ladder and wire mesh excel, while solid-bottom trays restrict airflow. Load Capacity is the tray's maximum safe cable weight per span, considering deflection limits and material strength. I've seen a 600A feeder run in a solid-bottom tray derate so severely that the conductor temperature exceeded 90°C rating within two hours of full load — the engineer had assumed that because the tray. Cable tray (or cable ladder) systems are a popular alternative to electrical conduit systems, as they have an outstanding record for dependable service, design flexibility and cost savings in commercial and industrial applications.
