I was planning on driving a ground rod when replacing overhead service to a detached garage. I was talking to the elec inspector at the jobsite. He said, "no, you don't need to because you are replacing the overhead existing triplex with quadplex 4 wire. You'll have 4 wires." I was surprised and asked him about that. The service panel will be a 4 breaker main lug subpanel.
