What Our Clients Say

Trusted by Industrial Teams Across Sectors

Real feedback from plant owners and engineers who've specified Burak Electric panels for critical operations.

“

The main distribution boards from Burakelectric are compact and well-rated for our 3200A incomer. Busbar joints are clean and torqued properly no hot spots after thermal imaging.

Product Education

What Is a Main Distribution Board (MDB)?

A Main Distribution Board, or MDB, is the central distribution board that receives power from primary sources like transformers or generators and divides it into smaller outgoing feeders for downstream distribution across a building or facility. On a single-line diagram it's often simply labeled the main panel, panel main, or mains board, all describing the same a distribution board at the head of the system.

 

Inside, a busbar system made from copper or aluminum carries the full incoming load to multiple outgoing feeders, each protected by its own circuit breaker. Integrated metering tracks voltage, current, and consumption, while the enclosure's IP rating (commonly IP40 to IP65) protects the electric board panel's internal components from dust, water, and other environmental factors. As the first major distribution board after the transformer, the MDB's reliability directly determines the reliability of every downstream circuit it feeds.

What Is a Main Distribution Board (MDB)?
Problem Awareness

What Happens Without the Right MDB Panel

01

Single point of failure

As the primary distribution board, an undersized or poorly protected MDB risks the entire facility's power

02

Inadequate enclosure rating

A low IP rating in a dusty or wet environment accelerates component degradation.

03

No integrated metering

Without real-time monitoring, faults and inefficiencies downstream go undetected.

04

Poor grounding

Improper earthing at the main panel level creates safety risk across every downstream circuit.

Capabilities

What Makes Burak Electric's MDB Panels Different

Built for the operating conditions of real industrial environments not just the test bench.

Current & Voltage Rating (415V, High Current Capacity)

Designed to handle specific current and voltage levels, supporting the full electrical load and system requirements of any db panel board.

Enclosure & Protection Class

Housed in enclosures rated for resistance to dust, water, and environmental factors (IP40–IP65).

Busbar System

Copper or aluminum busbars distribute power efficiently and support high current flows.

Metering & Monitoring

Integrated systems track voltage, current, and power consumption for better diagnostics on the mains board.

Protection Devices

Circuit breakers safeguard against overloads, short circuits, and faults.

How a Main Distribution Board (MDB) Works

The step-by-step operating sequence inside every Burak Electric MDB panel.

1

Incoming supply

Power from the transformer or generator enters via ACB or MCCB incomers.

2

Busbar distribution

Copper or aluminum busbars carry the full load to outgoing feeder sections.

3

Outgoing protection

Each outgoing feeder is independently protected by MCCB or MCB breakers.

4

Metering & monitoring

Integrated meters track voltage, current, and power consumption in real time.

5

Downstream distribution

Protected power feeds sub-panels, MCCs, and end loads throughout the facility.

Business Outcomes

What This Means for Your Operation

Fewer surprises. Faster diagnostics. A panel that's still right for you after you scale.

Common Questions

Frequently Asked Questions About MDB Panels

What is the difference between an MDB and a sub-distribution board?
An MDB is the primary, main panel receiving power directly from the transformer or generator, while sub-distribution boards (SDBs) sit downstream of the MDB, feeding smaller, localized circuits.
What IP rating do I need for my MDB panel?
IP42 suits clean indoor installations, while IP54–IP65 is recommended for dusty, humid, or outdoor environments. Our engineering team confirms the right rating for your site.
How many outgoing feeders can an MDB support?
Outgoing feeder count depends on panel size and current rating — share your facility's circuit count and our team will confirm a configuration for your distribution board.
What is the typical lead time for a custom MDB panel?
Lead time varies by current rating, feeder configuration, and component availability. Share your project details and our team will confirm an exact timeline with your quote.
What standards do your MDB panels comply with?
Our MDB panels are manufactured to ISO 9001:2015 and CPRI standards, engineered to IEC 61439 and IS 8623.
Does Burak Electric export MDB panels internationally?
Yes Burak Electric manufactures and exports MDB panels to industrial buyers beyond India, alongside domestic project work.
Are "main panel," "panel main," and "mains board" the same thing as an MDB?
Yes main panel, panel main, mains board, electric board panel, and a distribution board are all common ways site engineers refer to the Main Distribution Board. We build the same compliant db panel board regardless of which term appears on your drawing.
