Greg & John, I agree with both of you because that's my point. I am not PE either and each time I bring up this issue, I get kinda a vague response. I think that Greg is eluding to the code in 334.80 about NM cable and I agree with him. John, the handbook has an explanation of how to handle the situation when wiring passes through a high temperature area and I can understand that also. For my example, it's likely that the wiring could be in the high temperature area and terminate in the high temperature area. I think the code panel has some explaining to do. I submitted this same scenario to Charlie Trout's Code Question of the Day and I haven't gotten a response as of yet. And yes, John it's a "George question".
