Harold:
To continue this debate, I reply to your comments (IMHO)
Yes, if it is outside then it's a wet location, but the OP did not go there.
Going the UL route may be extreme, but it's a thought.
Derating, as the OP statement is not an issue I think. Greg did not mention any info leaning that way.
Your 10' rule of thumb would also be a tough thing to cite, as I'm not aware of any dimensions within the NEC for physical protection.
