New home construction, 200 amp service, I am installing the meter socket and connecting the grounding lug with 4 AWG cable to two 8' grounding rods placed 10' apart. The new 200 amp circuit panel is being installed inside behind the meter socket and will have the main disconnect inside. Do I need to run a 4 AWG cable from the neutral/grounding bar in the circuit panel to the meter socket grounding lug? Or is it already grounded by the neutral on the service entrance cable? Or does it need to be grounded independently to a ufer or the plumbing?
Thank you.
