The means for grounding a 200amp delta service enterance panal? The grounded and the grounding are on the same bus bar, Where should I ground my grounding rod & #6 bare grounding wire?

The #6 wire that is require for a 200A main service is to be bonded to the ground bar of this main panel, as well as the water ground which is required to be a #4 wire. In a main panel such as this all of the grounding is bonded together, just make sure that you have each wire in a sererate terminal. I you run out of space you may add additional grounding lugs, or bars, as long as your panel is made for this.
I hope this helps!
