Is there power in the secondary distribution box
The Secondary Distribution Box (SDB) receives power from Main Power Distribution box via an extender cable and provides a central power distribution to feed normal branch circuits to the electric floor modules through snap-on extender cables. From the transformer's low-voltage side (0. 4kV), power is distributed to a main distribution panel (primary distribution box). These boxes have inner and outer doors, powder-coated exteriors, and are designed for safety and aesthetic appeal, with rainproof tops for outdoor work. Also called a distribution board, panel board, breaker panel, or electric panel, it is the central hub in an electrical system that divides incoming power into various subsidiary circuits.

Does a distribution box belong to a power distribution transformer
An electrical transformer box is a protective, enclosed unit containing a distribution transformer, which steps down high-voltage electricity to lower, usable voltages for homes and businesses. These boxes are commonly seen as green metal units on a concrete pad in neighborhoods with underground. Receiving electric energy: The fiber distribution boxes is connected to the power station or substation through cables and receives high-voltage electric energy. These cables are usually made of copper or aluminum and have good electrical conductivity properties. It takes electricity from the main source and safely sends it to different circuits in a home, office, or industrial setup. Without it, managing power would be messy, unsafe, and inefficient. In this guide, we'll explain what a power.
