Custom PCC panels for industrial power distribution
Tirupati Power Enterprises manufactures Power Control Centre (PCC) panels in Kolkata against the agreed project specification. A PCC receives the incoming low-voltage supply and distributes it to outgoing feeders. Your single-line diagram defines what the assembly must connect, protect and measure.
Tell us whether the enquiry is for a new installation, a replacement board or an extension to existing equipment. An extension needs the existing drawings and interface details as well as the new feeder requirement. A photograph can help identify the installation, but it cannot establish the electrical ratings.
| Project requirement | Configuration to review | Send with the enquiry |
|---|---|---|
| Single incoming supply | Incomer, outgoing distribution feeders and metering. | Approved SLD, load schedule and supply characteristics. |
| Multiple incomers or bus sections | Source arrangement, bus coupler, interlocks and permitted operating modes. | Control philosophy; state whether any parallel operation is permitted. |
| Plant expansion | Additional feeders, spare capacity, space and connections to the existing board. | Existing GA/SLD, interface dimensions and proposed changes. |
| Replacement PCC | Existing cable interfaces, protection requirements and installation constraints. | Existing records, site dimensions and the planned replacement scope. |
PCC panel specifications needed for a comparable quotation
Attach the latest approved single-line diagram and a feeder schedule, with the drawing revision clearly identified. The project engineer must establish the system and protection requirements. If a value is not yet approved, mark it as pending rather than allowing competing quotations to make different assumptions.
Breaker interrupting capacity and the complete assembly’s short-circuit withstand are separate selection checks. Ask for the required assembly ratings and supporting verification for the proposed arrangement; a breaker catalogue rating alone does not verify the assembled panel.
| Specification | Information to supply | What it affects |
|---|---|---|
| Supply system | Rated voltage, frequency, phase/neutral arrangement, earthing system and source details. | Compatibility of the assembly, protection and control circuits. |
| Load and rated current | Incomer and feeder ratings, load schedule, operating diversity and spare requirements. | Busbars, protective devices, layout and thermal design. |
| Fault duty | Available fault level; specified withstand current, duration and peak rating where applicable. | Verification of the proposed assembly and protective-device arrangement. |
| Incomer and outgoing devices | ACB/MCCB or other specified device, poles, trip functions, fixed/drawout arrangement and accessories. | Component selection, maintenance access and replacement scope. |
| Busbars | Approved material, phase/neutral/earth requirements and connection arrangements. | Construction, termination space and the verified assembly configuration. |
| Protection and interlocks | Approved coordination requirements, trip/alarm functions and source/coupler interlocking. | Protection settings, control philosophy and wiring. |
| Metering and communication | Required measurements, CT details, instrument references, remote signals and communication protocol. | Metering equipment, interfaces and drawings. |
| Enclosure and environment | Indoor/outdoor location, ambient/site conditions, specified IP rating, separation form and ventilation. | Environmental protection, compartment layout and thermal assessment. |
| Access and cable entry | Front/rear access, top/bottom entry, cable sizes and quantities, gland plates and termination needs. | Board dimensions, cable bending space and site interfaces. |
| Approved makes and documentation | Make/series restrictions, substitution approval, standards, drawings, inspection plan and required reports. | A compliant offer with identifiable components and agreed evidence. |
PCC, MCC or APFC: send the enquiry to the right panel range
A plant may need several panel functions on the same project. Identify the duty of each board in the SLD so the quotation covers the correct assembly. PCC and MCC are often linked in the distribution system, while power-factor correction has its own selection inputs.
| Panel range | Main function | Useful enquiry information |
|---|---|---|
| PCC / main LT distribution | Receives incoming power and distributes it through outgoing feeders. | SLD, incomer/outgoing schedule, fault duty, metering and busbar requirements. |
| MCC / motor control | Groups motor feeders with the required starting, protection and control functions. | Motor schedule, starting method, duty and control/interlocking requirements. |
| APFC | Controls capacitor stages for the installation’s reactive-power requirement. | Load measurements, power-factor target, harmonic assessment and switching duty. |
| Distribution board | Distributes power to the circuits identified in its schedule. | Circuit schedule, protective devices, load ratings and enclosure arrangement. |
What determines the PCC panel price?
Request a project quotation rather than a price based only on the panel’s ampere rating. Two boards with the same nominal current can have different incomers, fault-duty requirements, feeder counts, enclosure arrangements and documentation scope. A comparable offer must describe these differences.
Send the approved specification and quantities for a line-by-line proposal. Where alternatives are acceptable, identify the approval process and ask for deviations to be listed separately. Price, taxes, payment terms, validity, lead time and delivery scope are confirmed in the written quotation.
| Cost driver | Check in the offer | Avoid an incomplete comparison |
|---|---|---|
| Switchgear and protection | Make, exact series, ratings, trip units, poles and accessories. | A different breaker or omitted accessory can change the scope. |
| Busbars and construction | Material, specified ratings, separation, enclosure and finish. | Enclosure dimensions alone do not define an equivalent assembly. |
| Feeder and control scope | Feeder quantities, interlocks, metering, communication and spare provision. | Show optional items and exclusions explicitly. |
| Verification and inspection | Agreed design-verification evidence, routine-verification records and FAT scope. | Clarify what evidence applies to the proposed assembly. |
| Delivery and site work | Packing, freight, insurance, unloading, installation and commissioning responsibilities. | Confirm which items are included, optional or by the purchaser. |
Agree drawings, verification and acceptance before manufacture
Specify the applicable edition of the assembly standard and the project requirements in the RFQ. IEC 61439-2 addresses power switchgear and controlgear assemblies; agree its application with the project engineer and the associated IEC 61439-1 requirements. A statement about an individual component does not establish compliance of the whole PCC.
Before fabrication
Agree the drawing submission and approval stages. Record the approved revision and resolve deviations before the relevant work proceeds.
- Single-line diagram, general arrangement and feeder schedule.
- Component/BOM references, control wiring, terminal and metering details as required.
- Dimensions, access, cable entry, foundation/interface requirements and shipping sections.
Verification and factory acceptance
Design verification and routine verification have different purposes. Ask which design-verification evidence supports the proposed assembly, and agree the routine-verification records and witness points for the actual board. If a CPRI or other laboratory report is required, check its applicability to the specified configuration and ratings rather than relying on a general logo or claim.
- Inspection and test plan, acceptance criteria and purchaser witness requirements.
- Agreed checks of construction, wiring, interlocks, metering and protective functions.
- Recorded deviations, corrections and the agreed release-to-dispatch process.
Handover documents
List the records required with delivery, including approved/as-built drawings, the final BOM, applicable verification records, device documentation and any separately agreed warranty terms. Confirm who will install, test and commission the panel at site.
PCC enquiries from Kolkata, Odisha, Assam and across India
TPE’s office and panel works are in Kolkata. We handle enquiries for West Bengal, Odisha, Assam and other Indian destinations from this Kolkata base. Share the delivery address and PIN code so the quotation can identify the dispatch point, freight arrangement and delivery responsibilities.
For a large board, confirm access restrictions, shipping-section dimensions, packing and insurance requirements, unloading equipment and site readiness. Tell us about a planned shutdown or required-on-site date at enquiry stage. The offered manufacturing and dispatch schedule depends on the agreed specification, drawing approvals and commercial terms; no standard delivery period is implied.
- New project: attach the SLD, feeder schedule, specification, quantity and required-on-site date.
- Replacement or extension: add the existing drawings, interface information and photographs.
- Order review: approve the final scope, deviations, drawings and inspection/dispatch milestones.

Before you request a quotation
Do you manufacture PCC panels in Kolkata?
Yes. Tirupati Power Enterprises manufactures custom electrical panels, including PCC panels, in Kolkata. Send the project SLD, feeder schedule, approved ratings and delivery PIN code so we can confirm the proposed construction, component makes, documentation, price and dispatch scope.
What is the difference between a PCC panel and an MCC panel?
A PCC receives incoming low-voltage power and distributes it through outgoing feeders. An MCC groups motor feeders with their starting, protection and control functions. Identify both duties in the project SLD and provide a separate schedule for each required assembly.
Can you quote a PCC panel from the ampere rating alone?
An ampere rating is insufficient for a comparable project quotation. Provide the SLD, feeder counts and ratings, supply and fault-duty requirements, busbar specification, approved makes, enclosure/access details, metering and required verification documents. Mark any unapproved inputs as pending.
Can I request copper or aluminium busbars and a particular switchgear make?
State the approved busbar material and component make/series in your enquiry. The proposed construction must satisfy the agreed project requirements and applicable verification. Availability, substitutions and any deviations are confirmed in the written offer; a brand reference does not establish dealership or stock.
Does an IP rating establish internal separation or short-circuit withstand?
No. IP protection, internal separation and short-circuit performance address different requirements. Specify each requirement separately and request the evidence applicable to the proposed assembly. The project engineer must approve the selection.
Is a CPRI test certificate included with every PCC panel?
Do not assume this from a catalogue page. State the required standard, ratings, test or verification documents and laboratory-report requirements in the RFQ. Ask for the applicable evidence and inspection scope to be identified for the actual proposed assembly before order placement.
Can you supply PCC panels for projects in Odisha or Assam?
TPE handles outstation enquiries from its Kolkata base and ships across India. Send the destination PIN code, delivery scope, site-access restrictions and required-on-site date. Freight, packing, unloading responsibilities and the offered dispatch schedule are confirmed in the quotation.
What affects the price and lead time of a PCC panel?
Switchgear, fault-duty requirements, busbars, feeder count, enclosure/separation, control and metering scope, verification documents and delivery arrangements affect the offer. Drawing approvals and agreed commercial terms also affect the schedule. Request a quotation for the complete approved scope.
