What is a Cable Tray System?
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.”
What does this mean?
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 across open spans.
Therefore, think of cable tray as the structural component of a building’s electrical system.
