There is no grounding ability to it at all. All grounds on our aircraft are wired, not frame grounds, and they go from negative terminals to ground busses and thence to the battery. I have been meticulous to avoid any wiring situation where a ground loop could occur as well. The panel fascade with its switches is currently laying on the floor of the cabin.
