Multiple ground rods, correct connections?

[Don Warneke]

I am getting conflicting requests from inspectors. I have always run ground wires from each ground rod back to the panel for the grounding system, and never had an issue with the inspections. Now I have an inspector that is requiring a wire to run from the first ground rod, to the second, then back to the panel. Which is correct?

Either or both
Neither are wrong

From the panel to the first rod and then from the first rod to the second would also be correct.

As long as both are hit and with the correct size conductor it will comply.

As Mike said either way would be compliant. I would add that if you did go from the panel and then from rod to rod the conductor would not have to be continuous between the two rods. You could install a jumper from the first rod to the next.

Makes no difference if you run the in serial or parallel fashion.

Don,

If I am understanding your opening post correctly, the inspector is requireing a conductor from the panel to each rod and a conductor between the rods? If that is the case, the inspector is requireing more than code. A separate conductor to each rod as you have been doing in the past is code compliant. A conductor to one rod with a bonding jumper to the next rod is also code compliant. But a loop from panel, to rod, to rod, to panel is not required. And there is no code basis for the inspector to disallow your previous method of doing it.
