Master Earth Grounding bus bar
This section highlighted in green will be connected to a variety of low resistance ground sources, including wet soil rods, cold water pipe, etc. The main Breaker Box (inside the house) will have a grounding cable running to this Master Earth Grounding bus bar.
A much older house nearby in the same neighborhood has a suboptimal (much smaller, and heavily corroded grounding bus bar mounted on a wooden board) with bare wires inserted. The only good thing going for it are the very clear plastic labels, LOL. Frankly speaking, I have no idea how this bus bar does what it's supposed to do!
