Correct answer to question 1104
- C: 60 degrees C
Explanation
110.14(C)(1)(a) bases termination provisions for these smaller circuits on 60 degrees C conductor ampacity unless the equipment is listed and identified for 75 degrees C. A 90 degree conductor may be used, but its ampacity is limited to the termination rating.
