Chapter 23.1, Problem 17R

Electric heating cable embedded in plaster, or sandwiched between layers of dry wall, creates heat. Therefore, any nonmetallic-sheathed cable run above these ceilings and buried in insulation must have its current-carrying capacity derated according to the (40°C) (50°C) (60°C) correction factors found in Table 310.15(B)(2)(a) in the NEC. (Circle the correct answer.)
