What is Ampacities for Cables in Trays about?

The document discusses a method for calculating ampacities (allowable current) for cables in randomly filled cable trays. It begins by noting that tightly packed cables restrict air flow, which normally carries heat away from cables. The method treats the cable tray as tightly packed and aims to distribute heat uniformly across the tray cross-section. It calculates ampacities based on each cable
