Use of Bus Bars adminKeymaster August 8, 2023 at 3:05 pm Can I use a bus bar for grounding? Like adminKeymaster August 8, 2023 at 3:05 pm Yes, some setups even tie the battery negative to the ground. With the setup you have you really aren’t hooked to ground. But if you hooked it to your house wiring then you would be really tied to ground.
