Why does the disconnect have to be on the exterior of the detached garage? Code reference? 2008 NEC.

It doesn't:

225.32 Location.
The disconnecting means shall be installed either inside or outside of the building or structure served or where the conductors pass through the building or structure. The disconnecting means shall be at a readily accessible location nearest the point of entrance of the conductors. For the purposes of this section, the requirements in 230.6 shall be permitted to be utilized.

I'm sure this is the same in the 2008, as all I have here on this computer is the 2002
