What size breaker should a 14 AWG copper wire be connected to?

15 amp
20 amp
30 amp
10 amp

The correct answer is: 15 amp

A 14 AWG copper wire is typically rated for a maximum of 15 amps, making a 15 amp breaker the appropriate choice for this wire size. This rating is based on the American National Standards Institute (ANSI) guidelines and the National Electrical Code (NEC) standards, which establish safe practices for electrical installations to prevent overheating and potential fire hazards. Using a breaker rated higher than 15 amps, such as a 20 amp or a 30 amp breaker, could lead to serious safety risks because the wire may not be able to handle that much current without overheating. The 10 amp breaker would also be underutilizing the capacity of the wire, although it is safer than a higher-rated breaker. Ensuring that the breaker matches the wire gauge is crucial for both performance and safety in electrical systems.
