The code reads:
250.54 Auxiliary Grounding Electrodes.
One or more grounding electrodes shall be permitted to be connected to the equipment grounding conductors specified in 250.118 and shall not be required to comply with the electrode bonding requirements of 250.50 or 250.53(C) or the resistance requirements of 250.53(A)(2) Exception, but the earth shall not be used as an effective ground-fault current path as specified in 250.4(A)(5) and 250.4(B)(4).
The code means:
Grounding electrodes, such as ground rods, that are connected to equipment are not permitted to be used in lieu of the EGC, but grounding electrodes may be used to establish a reference to ground in the area of electrically operated equipment. The earth may not be used as the EGC or effective (ground) fault current path. Auxiliary grounding electrodes are not required to be incorporated into the grounding electrode system for the service or other source of electrical supply.
