NEC Table 722.135(B) covers which of the following?

• A. power-limited cables
• B. listed cables
• C. cables in buildings
• D. cable substitutions

Answer: (C)

The main idea here is understanding what NEC Table 722.135(B) is addressing: which cables are permitted for use with power-limited circuits inside buildings. This table defines the types of cables that are allowed for installation within building spaces for these circuits and sets any caveats or conditions that apply to those interior installations. That focus on what can be used inside a building for power-limited applications is why it’s about cables in buildings. It isn’t a general rule about all power-limited cables in every setting, nor is it about listing or substituting cables. Those topics—whether a cable is merely listed, or whether substitutions are allowed—are outside this table’s scope. The interior-building context is the key factor the table specifies.
