What is the maximum overcurrent protection for a 10 AWG copper conductor?

• A. 20 amperes
• B. 30 amperes
• C. 40 amperes
• D. 50 amperes

Answer: (B)

The maximum overcurrent protection for a 10 AWG copper conductor is set at 30 amperes. This standard is based on the National Electrical Code (NEC), which defines the allowable ampacity for different sizes of conductors. For 10 AWG copper wire, the NEC indicates that the wire can handle a maximum of 30 amperes under standard conditions. This allows for the safety and reliability of the electrical system, as excessive current can lead to overheating and potential fire hazards. While some larger conductors may have higher overcurrent protection ratings, it's essential to adhere to established codes to ensure proper safety practices. The knowledge of ampacity ratings helps electricians and engineers to design systems that are both efficient and safe for their intended applications.
