In a science lab, what is the ampacity of a circuit conductor with a GFCI breaker when the ambient temperature is 80°F?

In a science lab, when discussing the ampacity of circuit conductors under specific conditions, it’s essential to understand how temperature affects the performance of electrical wires. Ampacity refers to the maximum amount of electric current a conductor or device can carry before sustaining immediate or progressive deterioration.

For a circuit conductor protected by a Ground Fault Circuit Interrupter (GFCI) breaker, the ampacity ratings are typically determined by the type of insulation and the temperature rating of the wire. In this case, with the ambient temperature being 80°F, standard ampacity tables can be referenced.

The correct answer indicates that the ampacity of the circuit conductor is 12 amperes. This value aligns with standard practices for typical conductors used in residential settings, particularly with smaller gauge wires that are often employed in circuits requiring lower amperage, such as those found in science labs for specific equipment.

Choosing this option reflects an understanding of the typical wiring configurations and safety measures inherent in electrical installations, particularly those involving sensitive lab instruments, where a circuit designed for lower amperage (like a 15-amp circuit) can further safeguard against equipment damage while maintaining safety.

Hence, selecting this value demonstrates an accurate interpretation of safe and appropriate conductor ratings within an academic or professional laboratory
