Which statement is true about #14 AWG electrical wire?

1. #14 AWG is approved for use on 30 amp circuits

2. #14 AWG is always stranded core for flexible use

3. #14 AWG is approved for use on 15 amp circuits

4. #14 AWG always has two conductor wires

The correct answer is: #14 AWG is approved for use on 15 amp circuits

The statement that #14 AWG is approved for use on 15 amp circuits is accurate. This gauge of wire is standard for general use in residential and light commercial applications, specifically for circuits that require a maximum of 15 amps of current. In the National Electrical Code (NEC), #14 AWG wire is commonly used for lighting and receptacle circuits due to its ability to handle the electrical load safely without overheating. Other options do not hold true in the context of electrical wire applications. For instance, #14 AWG is not suitable for 30 amp circuits, as it would not be able to handle such a load without posing a significant risk of overheating and failure. Additionally, this gauge can be either stranded or solid core, not exclusively one or the other; stranded wire is more flexible but not mandatory. Lastly, while #14 AWG can indeed be found with multiple conductors, it does not always consist of exactly two; it can have various configurations depending on the application.
