An electrical sub-panel, also known as a secondary panel or breaker box, is a smaller service panel installed downstream from your main electrical panel. While the main one is the primary distribution point for electrical circuits in your home, the sub-panel is a secondary. 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. The SDB can be fitted with terminal blocks for custom. These smaller breaker panels, also known as sub-distribution boards, are commonly used to provide power to secondary circuits within a building. Understanding the components and wiring configuration of an electrical sub panel is essential for safe and efficient electrical installations. It.
