Don't have a code book handy, but I believe you can't fill more than forty
percent. Personally, when it comes to boxes of any type, I like the biggest
I can fit rather than the smallest that's permissible

Additional Information
===================================
I am sorry -- that was a typo -- I used SER.
The panels are 25' and 50' away from the main panel.

Additional Questions Raised
===================================
I looked at table 314.16(A/B) but was unable to locate the size box I
would need for 10 2AWG wires. How many in^3 does each 2 AWG wire
require? Is there another calculation mechanism I need to use?
