MAIN LT PANEL The *Main LT (Low Tension) Panel* is the *main electrical distribution board* that receives power from a transformer (typically at 415V) and distributes it to various sub-panels or loads within a building or facility.

*Key Features of Main LT Panel:*
- *Voltage level:* 415V (3-phase) / 230V (single-phase)
- *Receives power* from the secondary side of a transformer (HT to LT)
- *Distributes power* to sub-panels like lighting panels, power panels, MCC, etc.
- *Protection devices*: MCCBs, ACBs, MCBs, surge protectors, etc.
- *Includes metering* (voltmeters, ammeters, energy meters)
- *May have automatic changeover* systems (for generator backup)

Functions:
- Central point for electrical power control and protection
- Ensures safe distribution of electricity
- Helps isolate faults and prevent overload

It's critical in commercial buildings, factories, hospitals, and large residential complexes.
