Routing power in computer raised floor ?

[Dale001289]

They have a raised floor (2’-0”) in a prefab substation. They want to run 480V power from there into MCCs, bottom entry
Is there anything wrong with doing this?
(normally only route 24VDC in raised computer floors, not sure about 480v power)

No. It would need to be a chapter 3 wiring method, ie, mc cable, etc

This would be TC-ER cable 600V insulation with XHHW-2 90 degree C, wet/Dry, routed in c tray affixed to the floor. Thank you for feedback.

He didn't say it wouldn't be.
