The damaged power cord on a 120-volt appliance can be replaced with a 6-ft length of flexible SJO cord not smaller than ___ AWG, connected to a 15-A branch circuit.

When replacing a damaged power cord on a 120-volt appliance connected to a 15-amp branch circuit, it is essential to select a cord that can safely carry the required current without overheating or failing. The National Electrical Code (NEC) provides specific guidelines for the minimum wire size needed based on the amperage and application.

For a 15-amp circuit, the minimum acceptable wire size is 14 AWG. This wire size can handle the current safely and is commonly used for applications with similar specifications.

Choosing a 14 AWG SJO cord ensures that it meets the necessary requirements for both carrying capacity and safety considerations. SJO cords are designed for additional flexibility and are suited for use in moderately harsh environments, making them a practical choice for appliance power cords.

Using wire smaller than 14 AWG, such as 18 AWG, would not provide adequate current-carrying capacity and could pose a risk of overheating under load. Similarly, while 12 AWG and 10 AWG wires could technically be used, they are larger than necessary for a 15-amp circuit, which might lead to unnecessary costs and less flexibility in the cord. Thus, 14 AWG is the most appropriate size for this
