I disagree. 250.50 says, "All grounding electrodes as described in 250.52(A)(1) through (A)(6) that are PRESENT AT EACH BUILDING OR STRUCTURE SERVED shall be bonded together to form the grounding electrode system. Where none of these grounding electrodes exist, one or more of the grounding electrodes specified in 250.52(A)(4) through (A)(7) shall be installed."
At each building or structure means exactly what it says. If you feed a detached structure from another structure there must be one or more of the grounding electrodes described in 250.52(A)(4) through (A)(7) at each structure. This is exactly what 250.50 requires. I would like to know how you would justify utilizing the grounding electrode located at one building as the grounding electrode for a separate structure and still satisfy the requirement of 250.50. I don't care if the second building is only 1 foot away. If it is not attached, it is a separate structure.
