Question:
Good Morning,
My question is can nonmetallic sheathed cable be installed above a fire rated drop ceiling with a flat roof?

Answer:
Hi John,
The uses permitted for NM cable are provided in Section 334.10 and uses not permitted are covered in Section 334.12. The Type of construction could be a factor in this situation. If the construction os fire-rate (Type 1 for example) there are restrictions. the area above the drop ceiling is not fire rated, it could be permitted in one- or two-family dwelling applications as indicated in 334.12(2). There are some missing details in the question to provide an exact response, but hopefully this helps you get on the right track.
