Flexible cords ___ AWG and larger are used to supply approved appliances and are considered protected from overcurrent by overcurrent devices.

Flexible cords ___ AWG and larger are used to supply approved appliances and are considered protected from overcurrent by overcurrent devices.

• A. 18
• B. 16
• C. 14
• D. 12

Answer: (A)

Flexible cords used to power approved appliances are treated as protected by the circuit’s overcurrent device when their conductor size is 18 AWG or larger. This means the branch-circuit OCPD provides the necessary protection for the cord, so there’s no separate fuse or protection built into the cord itself. 18 AWG is the minimum size noted for these flexible cords, and larger gauges (16, 14, 12, etc.) also fit the same rule. The key idea is that for these cords, the circuit’s overcurrent protection is considered to shield the cord from overcurrent, provided the cord is listed for the用途 and used in compliance with its listing.
