If a sub-panel is run to a garage from the house, which has 200amp 1 phase 3wire, does the ground wire need to be run with the conductors to the sub panel,(4 conductors) or can a ground electrode be installed at the garage and thus eliminate the ground wire in the pvc? The house is where the service entrance is and the conductors are buried in pvc to the garage. The neutral is isolated at the sub panel also.
