I have a 3 phase 480/277 outside service utility transformer. Underground service conductors run to Meter and then adjacent disconnect outside of building. The EC has a grounding electrode running from the meter to rod and also from the main disconnect to rod.
Is this legal?
I thought it you could on hit one or the other.
