What is a Cable Tray System?
As per the “National Electrical Code”, a cable tray system is “a unit or assembly of units or sections and associated fittings forming a rigid structural system used to securely fasten or support cables and raceways. Cable trays support cable the way that roadway bridges support traffic. A bridge is a structure that provides safe passage for traffic across open spans. Cable tray is the bridge that allows for safe transport of wires/cables across open spans. Therefore, think of cable tray as the structural component of a building’s electrical system.
