I was always under the impression that the ground wire must be sized for
the circuit overcurrent rating (i.e. breaker/fuse rating).  I have on
several occasions specified circuit (and neutral) ampacities greater
than the overcurrent rating just to eliminate voltage drop at the load.
 This is important in low-voltage (12/24/48 v) applications in comm centers.
