Do wires and cables share the same cable tray
While it is technically possible to run power and low-voltage cables in the same tray under strict conditions, segregation or shielding is strongly recommended to ensure safety, compliance, and system reliability. Cable trays are a support system for electrical cables, power, signal, and communication and optical fiber cables. NEC section 300-8 does not permit any tube, pipe, or equal for water, air gas, drainage, steam, or any service other than electrical in raceways or cable trays containing. I have surveyed a site where power wiring and data wiring share the same 18inch cable tray mounted above the racks in an article 645 space (with no raised floor?).
