Optical Fiber Cable and Raceway Rules: Mastering NEC guidelines requires a thorough understanding of Art. 770

摘要

Time for a quick pop quiz. Where does the NEC provide all of its requirements for wiring methods? If you answered Chapter 3, you are almost correct. When installing optical fiber cables, the requirements for wiring methods are located in Art. 770. Only when Art. 770 references sections in Chapter 2 and Art. 300 do these apply to optical fiber cables and raceways [770.3].
