This article will explore the importance of seismic resistance in cable trays, discuss when seismic braces are necessary, and help you understand how to make informed decisions for your installation. Eaton's TOLCO seismic bracing solutions help protect people and non-structural components during an earthquake. During an earthquake, cable trays are exposed not only to gravity loads and normal service loads, but also to lateral movement, vertical acceleration, vibration, and building drift. Cable tray runs in seismic zones need more than normal hanger spacing. A coordinated seismic bracing system uses strut channels. High-seismicity projects place much greater demands on cable tray systems than ordinary installations.
NEC Article 392 covers the requirements for cable tray systems, including the types of trays recognized, which wiring methods can be installed in them, where they can and cannot be used, how they must be supported, and the rules for grounding, cable fill, and ampacity. NEC Article 392 outlines the key rules for installing and maintaining industrial cable tray systems. These systems, made from metal or plastic, are open structures designed to support electrical conductors, ensuring proper organization and safety. 305(a)(3), or comparable standards promulgated by States. maintain spacing or to keep cables in place when the tray is ect the minimum bend ra-dius for cables as they exit the bottom of the cable tray.
