Hi I have a mobile home that has a 100 amp service in it I think it is a Sylvania and a 200 amp service square D on a pole in the front yard. The 200 amp service has a 100 amp breaker that is wired to the garage and there is another 100 amp breaker in the service for a building that was removed from the property. My question is can I run a 2-2-4 to the mobile home under ground and hook up a grounding rod to the mobile home box
