What is the maximum overcurrent protection for a 14 AWG copper wire?

The maximum overcurrent protection for a 14 AWG copper wire is set at 15 amps according to the National Electrical Code (NEC). This specification is based on the wire's ability to safely conduct current without overheating or becoming a fire hazard under typical conditions.

14 AWG copper wire is well-suited for circuits that do not exceed 15 amps, ensuring that the wire can handle this load safely. If a circuit were to be protected at a higher rating, such as 20 amps, it could allow too much current to flow through the wire, potentially leading to overheating and damage.

The NEC guidelines help ensure safety in electrical installations, making it critical to adhere to these overcurrent protection ratings. Therefore, choosing 15 amps as the maximum for 14 AWG copper wire aligns with safety standards and ensures reliable operation of the electrical system.
