In the 2011 NEC, Chapter 9, Table 5, on the first page, dimensions are shown for #12 and #14 RHH, RHW, and RHW-2, but there is a line under the wire descriptors and there is no wire type shown for sizes #10 - 2000. In the 2008 code that line is not there, so all those dimensions refer to RHH, RHW, and RHW-2 as well. My take on it is that line was placed there erroneously in the 2011 code. Do you concur? It makes a difference to a design I am working on.

In my copy of the book, the table is filled in for #10 through #2000, including the wire descriptions and the dimensions. I see underlines below sizes 1, 4/0, 600, and 1000, but I think that is just to make the table visually easier to read. Perhaps there was a printing error on your copy? :?

OK, I looked again. Perhaps I misunderstood the question. In my copy of the 2011, there is no line under the descriptions "RHH, RHW, RHW-2." The lines I mentioned earlier are under the tabulated values, but not under the wire types.
