What a PCC Panel Is, and What We Build
PCC stands for Power Control Centre. It is the board that receives the incoming supply from the transformer or the generator and distributes it to the plant's outgoing feeders — MCCs, utility boards, lighting boards and large individual loads. It is the single point at which the whole plant's power passes, which is why its busbar, its incoming device and its fault withstand set the ceiling for everything downstream.
Wisdom Techno Solutions builds PCC panels to order at our works in Vadodara, Gujarat, for industrial plants, EPC contractors and infrastructure projects across India. Every board is engineered against your single line diagram, load list and system fault level — not adapted from a standard catalogue design.
- Busbar systems to 6300 A, copper or aluminium, Form 1 to Form 4B separation
- Built inside design-verified licensed systems — Rittal Ri4Power, C&S CX, Siemens SIEPAN
- ACB or MCCB incomers, fixed or draw-out, with bus coupler and interlocking where specified
- Modular construction with separate chambers for busbars, cables and functional units
- Multifunction metering, protection relays and Modbus communication where the project needs them
- Busbars, switchgear, wiring and enclosure assembled and tested in-house, with a FAT report on every board
From a single-incomer distribution board to a two-incomer-plus-bus-coupler assembly with mimic bus and metering, the specifications below cover our standard build. Applicable ratings are confirmed against your specification before manufacturing begins.

| Testing | Routine verification in-house on every assembly; customer, consultant and third-party witnessed FAT supported |
PCC Panel vs MCC Panel
The two boards are often bought together and confused with each other. They do different jobs, and specifying one when you need the other is an expensive correction after the GA drawing is approved.
| Consideration | PCC (Power Control Centre) | MCC (Motor Control Centre) |
|---|---|---|
| Job it does | Receives incoming supply and distributes it | Switches, starts and protects motors |
| Sits where in the system | Immediately after the transformer or DG | Downstream of the PCC |
| Typical incomer | ACB, often 1600 A to 6300 A | ACB or MCCB, sized to the motor group |
| Feeder content | Outgoing distribution feeders to boards and large loads | Starter feeders — DOL, star-delta, soft starter, VFD |
| What sets the busbar size | Transformer rating and total plant load | Sum of connected motor loads with diversity |
| Form of separation | Form 2 to Form 4B, depending on maintenance philosophy | Form 3b or Form 4B is common, because feeders are worked on live |
| Metering | Incomer metering is essential; feeder metering optional | Usually ammeter or motor protection relay per feeder |
| Fault level exposure | Highest in the plant — closest to the transformer | Lower, limited by the upstream device and cable impedance |
When a Separate PCC Is the Right Choice — and When It Is Not
A separate PCC earns its place where availability matters and the plant is large. Distribution and motor control sit in different enclosures, so a fault in the MCC does not involve the distribution board, and either can be shut down for maintenance without the other. On a plant that cannot lose both at once, that separation is the whole point.
It is the wrong choice where floor space is the binding constraint and the motor group sits close to the incoming point. Two boards mean two sets of incoming gear and an interconnecting cable run sized for the full MCC load. On a compact plant room a PMCC — distribution and motor control in one assembly — removes both. That decision belongs at the layout stage, not after the GA is approved.
What to Send for a PCC Panel Quotation
Send these and every offer you receive will be comparable:
- Single line diagram
- Load list with connected and demand loads
- Transformer rating and impedance
- System fault level
- Required form of separation and IP rating
- Indoor or outdoor installation, single front or double front
- Busbar material, enclosure material and paint shade
- Metering and communication requirements
- Spare feeder and future expansion provision
- Applicable standard, with part and year
Where the load list is not ready we can build an offer from the transformer rating and an outline feeder schedule, and refine it once the list exists.
Common Mistakes in PCC Panel Specifications
- Sizing the busbar on today's load. The transformer rating, not the present load list, sets the ceiling on a PCC — and the board will outlive several load changes.
- Specifying a bus coupler without specifying the interlocking. Two incomers and a coupler need a stated transfer philosophy, manual or automatic, with the 2-out-of-3 interlock defined in the enquiry.
- Copying the form of separation from an old tender instead of deciding it from the plant's maintenance philosophy.
- Omitting the fault level from the enquiry. Without it no vendor can size the assembly correctly, and the offers stop being comparable.
- Writing "as per IEC 61439" with no part and no year. The verification evidence a manufacturer submits has to be traceable to a specific standard and configuration.
How Wisdom Techno Solutions Builds PCC Panels
Wisdom Techno Solutions is a licensed partner for three design-verified switchgear platforms — Rittal Ri4Power since 2021, C&S CX since 2023 and Siemens SIEPAN Elite/8PU since 2024. We build inside each system's verified configuration and routine-verify every assembly in-house at our Vadodara, Gujarat facility. Under IEC 61439 the design verification belongs to the system owner and the routine verification to the assembly manufacturer — what that division of responsibility means for a buyer is set out here.
