Power Distribution Board Manufacturer in India

Accu-Panels Energy manufactures power distribution boards (PDB panels) in Ahmedabad, India for industrial plants, commercial buildings, utilities and infrastructure projects. A PDB receives supply from the main PCC or LT panel and distributes it to sub-circuits through air circuit breakers, MCCBs or switch-fuse units, with metering, indication and protection relays arranged for the loads it feeds. Each board is built from your single-line diagram and load schedule — incomer and outgoing feeder ratings, metering, cable entry and enclosure conditions are decided by the project, not by a catalogue — in a CRCA metal-clad enclosure with copper or aluminium busbars, colour-coded phases and neutral, and a seven-tank pretreatment and powder-coat finish.

Industrial power distribution board applications

PDB panels are used wherever a single incoming supply has to be split into protected outgoing circuits: plant sections and process areas, utility blocks (compressors, pumps, cooling towers), HVAC and chiller plants, commercial buildings and IT loads, warehouses, hospitals and institutional buildings, and as sub-distribution downstream of bus ducts or feeder pillars. Where the outgoing circuits are lighting-only, a lighting distribution board (LDB) is used instead; PDB panels handle the power circuits.

PDB panel design considerations

• Incomer and outgoing feeders — number, rating and breaker type (ACB / MCCB / SFU) from the SLD, with spare ways for future loads
• Protection philosophy — overcurrent, earth-fault and, where required, relay-based protection coordinated with the upstream PCC or LT panel
• Metering — ammeter, voltmeter and selector switches on the incomer; energy metering or multifunction meters where the project specifies
• Cable entry — top or bottom entry, gland plates and cable-alley width sized for the actual cable schedule
• Enclosure conditions — indoor or outdoor duty, ingress protection (the standard PDB enclosure is designed for not less than IP65 in accordance with IEC 61439), ventilation and corrosion protection
• Segregation — form of internal separation where the specification calls for it [VERIFY: standard form of separation offered for PDB]
• Short-circuit withstand — matched to the fault level at the point of installation [VERIFY: standard kA options for PDB]
• Future expansion — busbar reserve and space for additional feeders without replacing the board

Difference between PDB, PCC and LT panels

All three are LT (low-tension) switchboards, and the terms overlap in practice. A PCC (power control centre) is the main incoming board that receives power from the transformer or DG, houses the main ACB incomers and bus couplers, and distributes to large loads and sub-panels — it is the top of the plant’s distribution tree. LT panel is the broad category for any 415 V switchboard, including PCCs, MCCs and PDBs. A PDB is the intermediate or final distribution board fed from the PCC: smaller incomers, more outgoing ways, and located close to the loads it serves. Choosing between them is usually a question of where the board sits in the SLD and what fault level and current it must carry, not of construction — the same IEC 61439 build practice applies to all three.

Information required for a PDB panel quotation

• Single-line diagram showing the incomer and every outgoing feeder
• Load schedule with connected and running loads
• Incomer and outgoing breaker types and ratings, or the fault level if you want them selected for you
• Installation environment (indoor / outdoor, ambient, dust, humidity) and any dimensional limits on site
• Metering requirement (incomer metering, per-feeder metering, energy meters, CT class)
• Documentation needs — GA, schematics, BOM, routine-test report, any consultant format

Frequently asked questions

What is a power distribution board?

A power distribution board (PDB) is an LT switchboard that takes one incoming supply and distributes it to several protected outgoing circuits through circuit breakers or switch-fuse units, with the metering and indication needed to operate them safely.

What is the difference between PDB and PCC panel?

The PCC is the main incoming board fed directly from the transformer or DG; the PDB is the downstream board fed from the PCC that distributes to plant sections and equipment. The PCC carries the higher current and fault level; the PDB has more, smaller outgoing ways.

What information is required to design a PDB?

The SLD, load schedule, breaker ratings or fault level, installation environment, metering requirement and documentation format. With these the team can prepare a GA drawing and a technical proposal.

Can a PDB be customised for project requirements?

Yes. Feeder count and ratings, breaker makes, metering, cable entry, enclosure material and IP rating, segregation and spare capacity are all decided per project from your drawings.

What affects the cost of a distribution board?

Incomer rating and fault level, number and type of outgoing feeders, breaker and meter makes, enclosure size, IP rating and material, form of separation, and the documentation and testing scope. A firm price follows a reviewed SLD and load list.
