Cable Tray Cover

[gjabei]

Where is the location in the NEC, that requires cable trays to be covered for personnel protection (for example, a vertical cable tray to a transformer primary, where the high ampacity cables could be touched, if not covered). Type TC cable being used, not type MC.

What makes you think that it would be dangerous to touch high ampacity cables? Maybe you should not put your watch or credit card into the magnetic field though.
Unshielded high or medium voltage cables would be a different issue.

Although its completely understandable, customers find it scary, i have never placed a cover over the cables.
In indoor situations, your customer may think that overhead future work could over time cause damage and they feel is a risk they want to manage. I can agree somewhat but i cant see it being required.

if protection is required then box type raceway should have been designed in and understood..

i think your dealing with either a customer preference or a local juristiction / inspector preference.

IMO, the solid bottom cable tray with cover is required where use free cables (not in conduits) in the applications of the HVAC plenum system.
In addition to 392.18(c).
