Cable on a 30 KVA transformer

[Ed Holt]

Is it code to use cable on the secondary side of a 30KVA transformer located in a high bay. I found one it that does seem right.

What type "cable" ??
(Art 392 & 336 are two areas that might be applicable)

I look at a pic from another facility and i having trouble downing a pic.
It appears to be PVC coating with the correct size and number of wires. It's being held in place by a cord gripped.
I have always done conduit with flex going into the transformer.
