a. 30 amps

b. 31.2 amps

c. 25 amps

d. 28.4 amps

Answer 1

The ampacity of a 12-AWG THHN conductor in an ambient temperature of 70°F is typically 25 amps.

Step-by-step explanation:

The ampacity of a 12-AWG THHN conductor can be determined using the National Electrical Code (NEC) standard. For a 12-AWG THHN conductor in an ambient temperature of 70°F, the ampacity is typically 25 amps.
