Power cables can share the same cable tray as electrical cables
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. There are really two considerations insulation failure /damage- what sort if cable is the UTP (would the jacket of the lower rated cable hold off mains voltages ) if so then they could be as close as you like,otherwise it should be segragated by split duct or similar. The National Electrical Code (NEC) Article 392 plays a vital role in establishing standards for cable tray systems, which are essential components in modern electrical infrastructure. Do you know where off the top of your head this is talked about in the NEC? I have not been in this. Cable trays are a support system for electrical cables, power, signal, and communication and optical fiber cables.
