Im installing a new 200 amp overhead service to my old house. I have new mast and meter base installed and new main panel. I ran the copper wire from grounding bar in main panel to 2 copper rods 6 feet apart . The meter base and new panel are hooked together with 2" emt 6 inches long. It is ran through the knockouts in the meter base and new panel and i had to use reducing washers on both ends. How do i go about bonding this all together? thanks for the help
