Cable trays are structural systems designed to hold and route electrical and communication cables safely and efficiently. They can carry both low-voltage and high-voltage cables, depending on the installation requirements . Low-voltage cable trays are specifically intended for signal, data, and control cables that operate at voltages typically up to 50 volts, such as Ethernet, telephone, security, and building automation systems . High-voltage cable trays, in contrast, are designed for power distribution cables carrying much higher voltages, often in the thousands of volts .
While cable trays are essential for organizing and protecting low-voltage wiring, they are not classified as wiring themselves. The cables placed inside the trays determine whether the system is low-voltage or high-voltage. Proper installation requires separating low-voltage and high-voltage cables to prevent interference and comply with safety standards . In summary, cable trays are pathways that can carry low-voltage wiring, but the tray itself is not considered low-voltage wiring. The classification depends on the type of cables installed within the tray.
