When I first read the question I choose B as the answer. I think that 110-14 (c)(1)(b)would confirm this answer as the correct one. I also read 110-14 after the apparant confusion in some of the posts on this one. While I still think B is the answer to the test question, I am really confused by this sentence in 110-14(c). Conductors with temperature ratings higher than specified for terminations shall be permitted to be used for ampacity adjustment, correction, or both. What's up with this? This seems to be totally opposite of the termination rules. I thought ampacity adjustments were made by increasing conductor size not temperature ratings of the conductor. Could some of you sparkys shed some light on this.
