The ground buss and neutral buss are only separated in a subpanel, in which case there should not be a ground rod as the grounding comes from the main panel on a separate wire from the neutral. Installing a ground rod at a subpanel instead of running a fourth wire from the main not only doesn't give you a proper ground as it is not referenced to the grounded conductor from the utility transformer, it is dangerous and can cause a lot of damage from surges etc.
