Correct answer to question 4105
- B: 60 C
Explanation
110.14(C)(1)(a) requires terminations for circuits rated 100 amperes or less, or for 14 AWG through 1 AWG conductors, to use the 60 C column unless the equipment is listed and marked for a higher temperature. Unmarked terminals therefore limit the conductor to the 60 C ampacity.
