I have a 200 amp service. The meter is on one side of the wall and the main panel is on the other side. The main panel has a 200 amp breaker and the neutral and ground bars are connected together via bonding bar. It has 200 amp wire coming out of lugs going across the yard to another 200 amp panel with a main- the neutral and ground are not bonded together. Out of that panel is another sub panel beside it that the neutral and ground are not connected. Is this proper bonding?
