Inspector's Statement

The inspector states that it is not legal to terminate the grounding electrode conductor (GEC) from the two ground rods to the meter socket lug provided. He insists that the GEC must enter the building and go directly to the distribution panel.

NEC Requirements

The National Electrical Code (NEC) allows for terminating the GEC from multiple grounding electrodes to the meter socket in certain circumstances:

Section 250.24(B) states

"Where multiple grounding electrodes are used, the grounding electrode conductor(s) shall be connected to the common grounding point within the grounding electrode system."

Section 250.24(C) states

"The grounding electrode conductor, where connected to a meter or other enclosure, shall be connected to the grounding terminal on the load side."

Exception

However, there is an exception to this rule when the grounding electrode conductor is connected to a "combined grounding and bonding terminal" on the meter socket. This terminal must be properly marked as both a grounding and bonding point.

In Your Case

Since you have two ground rods and plastic water piping, you are required to install a GEC according to NEC 250.50(A).

Recommended Approach

Based on the NEC requirements and exception, the best course of action is to:1.

Check the Meter Socket

Verify if the meter socket has a combined grounding and bonding terminal.2.

If Available

If it does, you can connect the GEC from the two ground rods to the combined terminal.3.

If Not Available

If there is no combined terminal, you will need to run the GEC directly to the distribution panel.

Conclusion:

If the meter socket does not have a combined grounding and bonding terminal, the inspector is correct in stating that the GEC must go directly to the distribution panel. However, if there is a combined terminal, you are allowed by the NEC to terminate the GEC to the meter socket. Flag for review
