I will be adding in another meter box to separate the cost of electricity between 2 rooms. Does anyone know how the electric company will be running the neutral cable, ground, and hot wires? Will they be connecting the new ground and neutral to the old box since it is close by each other. (the two meters will be next to each other) For example, if for instance my house had a meter to it, and i wanted to add a small room in the backyard with another meter, is it possible to connect ground wires to the old breaker box even tho they both have separate meters? or does it need its own grounding rod?
