The regulations dictate that the cables must either be Type TC (also known as Tray Rated) or must be metal-armored (Type MC). Selecting the correct cable tray for low voltage system—such as data networking, telecommunications, security, and building automation—is a critical decision that impacts system performance, scalability, and long-term reliability. A poor choice can lead to signal interference, difficult. NEC Article 392 outlines the key rules for installing and maintaining industrial cable tray systems.
