Thank you for asking your question on You are corresponding with Jason - Your personal online "Electrical Consultant"HiCustomer In my jurisdiction, we never install ground wires to a meter base. It always connects to the electrical panel. There are 2 different Utility Companies in my area, and this is how both want the grounding to be done. Once again, they do not want ground wires connected to their meter bases.
However, I have been told that this is not the case in all municipalities. Electricians from other towns have told me that in their hometowns, they have to ground the meter base to meet local Codes. So to know for sure, you will need to call your local building department. But I suspect they will tell you not to ground the meter base.
