Electrical Grounding System

In the inspection process, I always get the chance to inspect electrical boxes. I always have someone ask. “How does the grounding system work?”
The ground wires are collected at the distribution panel and forwarded to the service box. At the service box, the house ground wires are connected to the service box equipment and enclosure. The whole assembly is connected to the service entrance neutral and to a grounding wire that goes to grounding electrodes (like plumbing pipes.) In some cases, the system ground may be connected to the grounding electrode conductors at the meter, rather than at the service box.
This gives the electricity, in theory, two choices to flow to ground. Electricity that comes back to this point can either flow to ground through the neutral service wire, or through the ground wire to the grounding electrode.
The earth grounding system (ground) wires running from the service box to the grounding electrode are usually copper and are often bare (no insulation). Aluminum wires are not as good conductors as copper, so they have to be on size larger than copper wires.
Just a little insight to help you better understand the electrical system in the home you are rehabbing.

HAPPY REHABBING!!!
