    GEC/System bonding jumper thru same lug for SDS

    Any potential violatIons on taking an GEC (coming from bldg steel for example) through a Single lug on XO and loop it thru and hit xfmr enclosure to also serve as the system bonding jumper? Say it’s a 75kva 480v to 208v xfmr typical setup, with bonding done inside xfmr. Looking thru 250.24 I don’t see that it would be. Correct me if I’m wrong
