I removed and replaced 4–0 SEU cable from meter can going into the electrical panel I installed two ground rods outside 6 feet apart then ran a number for ground from one to the other into the main electrical panel then ran a ground wire from the main electrical panel to the water shut off valve I then bonded to home at the water heater I separated grounds in neutrals so they are up to code install two ground bars and add-a-lug For oversized neutral I also removed and replaced the main breaker in the 200 amp electrical panel #review
