Has anyone looked in the 2011 NEC at Table 310.15(B)(3)(a) formerly known as 310.15(B)(2)(a). The heading of the Table apparently never got changed but look at the column "Number of Conductors" and its accompanying note.
It appears all the conductors in the raceway will count including the egc.
The footnote says see 310.15(B)(5) and(6), which states that the neutral in certain cases and the EGC are still omitted.
The change seems to merely clarify the fact that even though certain conductors may carry current at times, they may be omitted.
