I just found out that TV does not install a "driven ground" for the panel box. They are "bonding" the reinforcement rods in the foundation and using this for the panel box ground. The electrician told me it is acceptable in Sumter County. The rods are about 6 inches off the ground, inside the concrete. A good ground would be 25 ohms or less. I did not know concrete was a good conductor. In the Mid Atlantic states there needs to be a seperate ground rod at least 8 foot driven. I do see the need to bond & ground the reinforcement rod, but they need to also install a seperate driven in the "Lightning Capital of the US". Heading to Home Depot to install my own.
