still learning, but this is what i understood, 250-64(c) says the gec shall be installed in one continuous length without a splice or joint.
250-52 and 250-58 calls it "bonding" between the two electode rods, it says ge's "that are effectively bonded together" are considered a single ge system, but i don't see anything that specifies the route between two rods. looks like it could go from rod to rod directly, or from rod to panel bus to rod indirectly like your inspector wanted. but it does seem to imply bonding from rod to rod, and it also states specifically, and other places implies, that it is a "single" gec, thats why i loop through one to the next. they ought to use pictures, it wouldn't take much, theres not that many ways it can be done.
