What type of distribution box is the final stage box
The distribution box is divided into power distribution box and lighting distribution box, which is the last level equipment of the distribution system. The terms primary, secondary, and tertiary distribution boxes are relative. From the transformer's low-voltage side (0. 4kV), power is distributed to a main distribution panel. The answer is simple, but profound: An electrical box is defined by its mission, not its material.
