I am in the process of upgrading appliances in my home. I currently have a 100 amp breaker box and I am thinking of upgrading to a 200 amp box. The electrical cables coming into the meter from the electric company are burial cables that are not in conduit. The size of the cables are #2. Are #2 cables large enough to handle a 200 amp load if I were to ever max out the box? Also what is the correct wire size coming from the box to the new appliances? One appliance is 40amps and the other is 30amps. The distance from the appliances to the box is approximately 130 feet. I have received some conflicting information from different electricians and I am a little confused.
