Just like it is from the service panel back to the source.
BBQ, thanks. You're right. My bad. As noted elsewhere in this thread, the problem is that there are different versions of the pic in different editons of the NEC ( and, in fact, in my hard copy '08 NEC Handbook, right in front of me, there is for building 3 no neutral to ground jumper, which would be illegal as of some recent year anyhow, and also no path otherwise for ground fault current. But the pic from '11 NEC provided by Celtic shows a remedy, and so all is well. ).
