Have you seen one thats not dual rated?

Is THHN suitable for wet location

As mentioned above No, however most thhn wire is now both thhn and thwn wire. If it is just thhn then it is not suitable for wet if it is the combination wire then you are good to go.

take a look at 310.15 mr. smartypants...you can't use the 90D table for derating purposes if you use THWN in a wet location...

as for oil and gas...that's your problem

I couldn't resist.

By the way, if you want to wire a machine tool, make sure it says MTW on it too.
