What is the maximum overcurrent protection rating for a 14-gauge copper wire?

The maximum overcurrent protection rating for a 14-gauge copper wire is 15 amps. This rating is based on the National Electrical Code (NEC), which provides guidelines to ensure safe installation and operation of electrical systems. The NEC stipulates that 14-gauge copper wire can safely carry a maximum of 15 amps, which helps prevent overheating and potential fire hazards.

Using an overcurrent protection device rated above this maximum could lead to excessive current flowing through the wire, risking insulation damage and leading to safety hazards. Therefore, 15 amps serves as the standard for protecting 14-gauge copper wiring, ensuring safety and compliance with electrical codes.
