We are installing facilies into a construction trailer park. (approximately 30 trailers)We are providing 6 gang meter centers. From the meter center the electrical contractor is running a urd. cable to a 4 x 4 post that will have a 100 amp breaker. My questions is do I need an additonal breaker under the meter center or is the one breaker on the 4x4 post adequate. When the construction trailer owner hooks in to this system they will connect their wires into the 100 amp breaker on the 4x4 post.
