my old sub panel has 3 single strand 4awg which is ran to my meter loop on a 50amp breaker. Someone had cut a leg on both ends so now I can only get 120. Its only a 4 space sub. When I tried to add a third breaker for some reason it wouldn't work. also how do I wire in the new wires in the new sub box from the main?
