Can I use Table 310.15 (B)(6) to size Type SE cable for a 240/120 dwelling? What aboutTHW conductors? The reason I am asking is because I am preparing for the Masters and the literature I am using to prepare is using Table 310.16.

Whats weird is that in one question they ask what size THHN conductor to use and the answer they have comes from 310.15B6. Why did they use it here but not on the other two examples? Am I missing something?
 
Re: Service Entrance

The answer is yes to both type SE and THW.

For some reason, my 2002 copy does not list the conductor types permitted as it did in the 1999 edition. This list is back in the 2005.
