PCC vs MCC: Understanding the Key Differences
PCC vs MCC: Overview
Both PCC (Power Control Centre) and MCC (Motor Control Centre) are essential components of industrial power distribution systems, but they serve different purposes.
Power Control Centre (PCC)
Purpose
Main power distribution from transformer secondary to various sub-distribution boards and MCCs.
Key Features
- Incomer: ACB rated 800A-6300A
- Outgoing feeders: MCCB-based feeders for sub-distribution
- Bus coupler: For dual transformer configurations
- Metering: Comprehensive energy monitoring
Typical Components
- ACB with LSIG protection
- MCCBs for outgoing feeders
- Multifunction meters
- CTs and PTs for metering
Motor Control Centre (MCC)
Purpose
Centralized control and protection of electric motors.
Key Features
- Motor starters: DOL, Star-Delta, Soft Starter, VFD
- Protection: MPCB/MCCB + Contactor + Overload relay
- Control: Push buttons, selector switches, indicator lamps
- Metering: Individual motor monitoring
Key Differences
| Feature | PCC | MCC |
|---|---|---|
| Primary function | Power distribution | Motor control |
| Incomer rating | 800A - 6300A | 200A - 2500A |
| Outgoing devices | MCCBs | Starters |
| Protection philosophy | Selective coordination | Motor protection |
| Typical location | Near transformer | Near motor loads |
Selection Guide
- Use PCC when distributing power from transformer to multiple boards
- Use MCC when controlling multiple motors from a centralized location
- Large installations need both: PCC feeds MCC
Configure Both
