Roger you bring up a good point about the fan coil units construction.
Out of tradition, habit, etc. we always feed these tin boxes with weatherproof means even though I do not think it is actually required.
I also have wired a pre-fab walk-in that was all dry location equipment. The inspector did question it but let it drop.
Personally I will stick with the weather proof stuff 'cause it looks right'.
