I plan to do some remodeling and I will be installing a door in a wall that contains about 10 wires connecting to my breaker box in the basement. My thought was to install another breaker box beside the doorway and connect the wires to that in order to take them out of the doorway, and connect the two boxes together. The new box would be in the garage and we are planning to make an apartment above. We have a 100 amp entrance. Our power connects to the house by way of a 300' power ditch. Will my solution to the wires in the doorway be effective and efficient? Is there a better way? Can a new entrance and meter be installed with my existing power lines?
