A secondary distribution box (SDB) receives power from the main distribution box and distributes it to branch circuits within a building or floor . It acts as a local hub for electrical distribution, providing protection through circuit breakers or fuses and enabling isolation for maintenance or emergencies . Unlike the primary distribution box, which serves as the main power source, secondary boxes are installed closer to the load centers, such as individual floors, wings, or high-demand areas .
