Welcome to the forum, from another Jersey Guy
Your ? falls under Article 682, along with the other sections referenced.
As to GFI protection, a prudent move would be .....do it, Think about liability.
As to LV lighting, 12 volt....cable approved for sunlight resistance? (if required) Approved for wet/damp location??
I'm not "UP" on this Article, I'll read it tonite, time permitting.
