Table 400-4 in NFPA 70 lists various types of what?

• A. Flexible cords, some of which are noted as being designed for hard or extra hard usage
• B. Flexible cords
• C. Electrical outlets
• D. Conduit types

Answer: (A)

Table 400-4 in NFPA 70 lists the different flexible cords and cables by type, and it includes notes indicating that some of those cord types are designed for hard or extra-hard usage. This is why that option is correct: the table’s purpose is to categorize flexible cords and specify which designs are meant for tougher service conditions, rather than listing outlets or conduit types. Knowing this helps electricians pick the right cord for the environment and mechanical demands (outdoor exposure, abrasion, temperature, etc.). The other choices don’t fit because outlets and conduits are covered elsewhere in the code, while this table specifically focuses on flexible cords and their intended usage.
