Main Distribution Board (MDB)

Primary power distribution hub receiving supply from transformer and distributing to sub-circuits via ACBs and MCCBs. Rated up to 6300A. Houses main incoming breaker, bus-section, and outgoing feeders.

Sub-Distribution Board (SDB)

Secondary distribution from MDB to final circuits. Typically MCCB/MCB based, 100A–800A. Located at floor level or zone level in commercial buildings.

Power Control Center (PCC)

High-capacity centralized power distribution for large industrial facilities and data centers. Controls and distributes incoming power to MCCs, APFCs, and downstream loads. Typically 2000A–6300A.

Motor Control Center (MCC)

Centralized motor control with starters, contactors, overloads, and VFDs in standardized withdrawable or fixed functional units.

Low Voltage Switchgear (LVS)

Complete low-voltage switching and protection assembly for power distribution networks. ACB-based, draw-out construction, 630A–6300A.

Automatic Transfer Switch (ATS) Panel

Automatic changeover between utility supply and standby generator or dual utility feeds. Open transition (break-before-make) or closed transition (make-before-break).
