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. But with more and more cables and longer use, cables getting too hot is a big issue.
