I have always understood the code to mandate only one system ground at the point of first overcurrent protective device. Recently a new electrical inspector began doing our inspections. In the following example he is requiring a second ground electrode and I believe he is wrong. Please clarify and help me understand the reasoning. The installation involves a combination meter/disconnect with a main breaker. We have always grounded the system at that point and carried the ground downstream through the 4th wire. Now the new inspector has required us to add an additional ground electrode at the remote panel location. Is this correct? And if so why?
