Bonding at the service
There are a few systems that may be installed in your house which will need to be bonded to the service. The method of bonding these systems is essentially the same as grounding to your ground rods. Simply run the proper sized wire, connect to the clamp that you have secured to the pipe, and connect the other end to the ground bar at the main breaker panel or meter main panel. In the event you have a 320A service with two main breaker panels, unlike grounding, you need to bond to only one panel. Bonding clamps come in all sizes, for different pipe sizes, but are essentially the same as ufer clamps, with the exception that pipe bonding clamps can be made of aluminum instead of brass.
