Home / Should vertical cable trays be installed in the low-voltage room
Answer: Yes — NEC permits type MC (Article 330) and type MV (Article 328) in industrial establishments where qualified persons will service the installation. Multiconductor cables rated over 600 volts shall be separated from lower voltage cables by a separate cable tray or a solid. en completely installed, without damage either to conductors orstructural system use 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. The mechanical and electrical characteristics, tests, certifications, overall quality management, recommendations mentioned. This publication is intended as a practical guide for the proper and safe* installation of cable ladder systems, cable tray systems, channel support systems and associated supports. Segregation of Power and Signal Cables: Power (high-voltage) and signal (low-voltage) cables should be routed separately, using dedicated trays to minimize electromagnetic interference.
