Table 400-4 in NFPA 70 concerns what category of cords?

• A. Flexible cords
• B. Circuit breakers
• C. Switches
• D. Conduits

Answer: (A)

Flexible cords are evaluated for how much current they can safely carry. In NFPA 70, Table 400-4 lists the ampacities of flexible cords and cord sets, based on the cord’s gauge, insulation type, and temperature rating. This table helps you choose a cord that won’t overheat when delivering a specific load for portable or movable equipment. The table is not about circuit breakers, switches, or conduits, which are addressed elsewhere in the code. So Table 400-4 is about the safe current capacity of flexible cords.
