When running the grounding electrode conductor to a transformer a really clean way to terminate is to run through the grounding lug that's mounted to the can unspliced on it's way to XO. From the lug to the XO it doubles as the main bonding jumper. I realize that in a lot of cases you could end up with a undersized MBJ especially larger transformers but it works well on the smaller ones. My question is does this violate the listing of the lug it passes completely through? (The one mounted to the case) I have noticed that the conductor tends to loosen easily when applying this method. (for this reason I don't really like it) Using a quad lug on the case and running a separate MBJ is probably a better way. Any thoughts?
