They are one pole modular units with an interlocking dovetail feature that enables ganging of the blocks to create multipole configurations according to application requirements. This block has a Short-Circuit Current Ratings (SCCR) of up to 100 kA with fuses and circuit breakers. 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. Many feeders leave substation in a concrete ducts and are routed to a nearby pole.
