I have a 600amp servie on a steel frame building. My grounding electrode conductor is run from the service to the building steel. 200' from this point we bonded the metal water pipe to the building steel. All condutors are sized per 250.66. The inspector is requiring a grounding electrode conductor be installed the entire 200' to the waterpipe. The building is bolted together with no expansion joints.
The inspector is stating that there is no way to know for sure that the building steel has an effective ground path. My stand is that the bonding jumper to the water pipe assures and creates an effective ground path per 250.52(A)(2) even if it is 200' away.
I have read extensive threads on this subject but would like to know in everybodys opinion who is correct?
