PCC is a short form of Power Control Center. This is a heart of the control circuit. The output of the generators or transformers is given to PCC. The major power circuit equipments will be installed in this panel. It consists of circuit breakers, Busbar, PTs (Potential Transformer), CTs (Current Transformer), insulators etc. Major protection circuits will be installed in this panel to protect transformers, Motors, Generators etc. The output Power from the PCC panel will be distributed to MCC panels via feeders.

An LT Distribution Panel (Low Tension Distribution Panel) is an electrical panel used to distribute power from a transformer or generator to various loads at a lower voltage, typically below 1,000V (commonly 415V or 230V in industrial and commercial applications).

Key Functions of an LT Distribution Panel:

Power Distribution – Supplies electrical power to different circuits and machinery.

Load Management – Controls and distributes electricity efficiently to prevent overloading.

Protection – Includes circuit breakers, MCCBs, MCBs, fuses, and relays to protect against short circuits, overloads, and faults.

Monitoring & Control – Comes with meters, indicators, and control switches to monitor power usage and status.

Safety – Ensures electrical safety by isolating faulty circuits and preventing electrical hazards.

Components of an LT Distribution Panel:

Main Incomer (MCCB/ACB/MCB) – The main switch to control incoming power.

Busbars – Conductors distributing power across different circuits.

Outgoing Feeders (MCBs/MCCBs/ELCBs/RCCBs) – Distribute power to different loads.

Meters & Indicators – For voltage, current, and power factor monitoring.

Protection Devices – Surge protectors, fuses, and relays for safety.

Applications of LT Distribution Panels:

Industrial Plants – Power distribution for heavy machinery.

Commercial Buildings – Office power supply management.

Residential Complexes – Distributing power safely among flats or units.

Hospitals, Malls, & Hotels – Ensures uninterrupted power supply.
