Cable Tray Fill Rules (NEC 392)
Data centers almost exclusively use cable tray (usually wire mesh or ladder type) for both power and data cables because cable density is high and changes are frequent.

Mixing Cables Over and Under 600V in Cable Tray
At times it becomes necessary, or even desirable, to route medium- or high-voltage cables (greater than 600V) in the same cable tray with cables rated 600V or less.
Core Principles for Electrical and Instrumentation Cable Tray Layouts
Layered Separation: Strong current and high-voltage cables are positioned apart from low-current, low-voltage instrumentation cables. Layered separation reduces interference, preserving the quality of
392.20 Cable and Conductor Installation.
For example, in a facility where the maximum available voltage is 480 volts, it would be pointless to require separation in the cable tray between two sets of 480-volt conductors just because one set
Can You Run High & Low Voltage in Same Conduit? (NEC Rules)
The mixing of high voltage and low voltage wiring in a single conduit is generally discouraged due to safety considerations and potential interference issues. High voltage wiring

Why It Matters: High‑voltage and limited energy circuits routed too closely can cause cross‑talk, distortion, or packet errors, especially in dense cable trays or congested ceiling spaces.

NEC section 318-5 (e) indicates that multiconductor cables rated 600 volts or less are permitted in the same cable tray, however, separation of power and control cables is necessary as indicated in other
Can You Run Low Voltage With High Voltage?
Even when physical separation requirements are met, running high-voltage AC wires parallel to sensitive low-voltage signal cables can introduce performance problems through electrical
Running High Voltage and Low Voltage Wiring
All ETC equipment that uses both power and control wiring is designed to aid this separation and their installation manuals discuss both the fact that they should not be run together as well as how to feed

Scenario 2 - Could MC (600V) and MC (300V) cables be present in the same tray with no barrier if the highest applied voltage is 480V? In this case, the 300V rated MC would be industrial
