Understanding PCC vs MCC Panels: Which Does Your Plant Need?

What is a PCC Panel?

A PCC (Power Control Centre) is the main incoming distribution panel — it receives power from the utility or transformer and distributes to downstream panels, MCCs, and sub-distribution boards. Current ratings from 630A up to 6300A, with ACB or MCCB incomer, multiple outgoing feeders, and comprehensive metering.

What is an MCC Panel?

An MCC (Motor Control Centre) focuses entirely on controlling and protecting motors. Each outgoing feeder in an MCC is dedicated to one motor, complete with a motor starter (DOL, Star-Delta, or VFD), overload relay, and isolation. MCCs are typically supplied from a PCC or Main LT panel.

When to Choose PCC

For plants with incoming loads above 630A, multiple sub-distribution boards, complex feeder arrangements, or when centralised metering and power quality monitoring is required. PCC is the first level of distribution after the transformer.

When to Choose MCC

For plants with 4+ motor loads that need individual control, protection, and monitoring. MCCs are ideal when motors are geographically clustered and a centralised motor control location makes maintenance and operation efficient.

Key Specification Tips

For PCC — specify busbar rating, short circuit withstand (up to 100kA), number of outgoing feeders, metering requirements (V, A, kW, kWh, PF, Frequency, Harmonics), and SCADA integration. For MCC — specify motor kW ratings, starter type, IP rating, and control voltage (230V or 24VDC).
