MCC vs PCC Panels: What's the Difference?
The difference between a Motor Control Centre (MCC) and a Power Control Centre (PCC), and how they work together.
MCC and PCC panels both sit in an electrical distribution system, but they do different jobs. A PCC (Power Control Centre) receives the incoming supply and distributes power to loads and sub-panels. An MCC (Motor Control Centre) takes power and uses it to start, stop, control and protect motors.
In short
A PCC is about primary distribution and control at a higher current level, usually with an air circuit breaker incomer and heavy busbars. An MCC is about motor management, with many smaller starter compartments.
Working together
In a typical plant the PCC distributes power and feeds one or more MCCs, which in turn run the motors. Choosing between them is about the role at that point in the system, not one being better than the other.
How to decide which you need
If your question is how to bring in and distribute the main supply, you need a PCC. If it is how to start, stop and protect a group of motors, you need an MCC. Most plants need both, sized from the total load and the motor list. Share the incoming source, the loads and the motor details with your enquiry so that the right combination can be quoted.

- Can one panel do both?
- They are usually separate assemblies because their roles and ratings differ, though they are designed to work together.
