What Is a Power Distribution Board?
A Power Distribution Board (PDB) is an electrical panel that receives power from an incoming source and distributes it to multiple outgoing circuits or loads.
The distribution board provides a centralized location for:
- Electrical power distribution
- Circuit protection
- Isolation
- Feeder control
- Metering
- Load management
- Fault isolation
A typical arrangement can be represented as:
Incoming Supply → Main Protection → Busbar → Outgoing Feeders → Loads
The actual arrangement depends on the electrical design and project requirements.
How Does a Power Distribution Board Work?
The incoming electrical supply enters the distribution board through the main incomer.
The incomer may be equipped with suitable protection and isolation equipment such as an ACB, MCCB or isolator, depending on the system design.
Power is then distributed through the internal busbar system to individual outgoing feeders.
Each outgoing feeder can have its own protective device according to the connected load.
For example:
Incoming Supply
↓
Main ACB/MCCB
↓
Copper/Aluminium Busbar
↓
Outgoing MCCB/MCB Feeders
↓
Electrical Loads
This arrangement allows individual circuits to be protected and isolated without necessarily shutting down the entire distribution system, subject to the system design and operating conditions.
Types of Power Distribution Boards
Main Distribution Board
A Main Distribution Board (MDB) is generally installed at the main distribution point of a facility.
It receives power from the main source and distributes it to major downstream electrical feeders.

Protection Relays
Protection relays may be incorporated where additional protection functions are required by the system design.
Surge Protection Device
SPDs can be used where surge protection is required based on the electrical installation and protection philosophy.
Terminal Blocks
Terminal blocks provide organized termination for control and auxiliary wiring.
Protection Features
The protection system should be selected according to the electrical installation.
Depending on the design, a Power Distribution Board may include:
- Short-circuit protection
- Overload protection
- Earth-fault protection
- Over-voltage protection
- Under-voltage protection
- Phase-failure protection
- Surge protection
- Feeder isolation
- Metering and alarm functions
Not every PDB requires all of these functions. The final protection arrangement should be determined according to the electrical system and applicable design requirements.
Power Distribution Board for Industrial Applications
Industrial facilities often contain multiple electrical loads operating simultaneously.
A properly designed PDB can organize these loads into separate feeders.
For example:
Main PDB
→ Production Area
→ HVAC
→ Utility Loads
→ Lighting
→ Pumps
→ Compressor
→ Auxiliary Loads
Individual feeder protection makes it easier to isolate and maintain specific circuits according to the operating arrangement.
Power Distribution Board for Commercial Buildings
Commercial buildings generally have different categories of electrical loads.
A distribution system may supply:
- Lighting
- HVAC
- Elevators
- Pumps
- Fire systems
- Office equipment
- Common-area services

The PDB can be divided into appropriate outgoing feeders based on the building’s electrical design.
Power Distribution Board for Hospitals
Hospitals have electrical systems with different categories of loads and operational requirements.
Distribution boards may be used for suitable applications such as:
- HVAC
- Lighting
- Pumps
- Utility systems
- General electrical loads
- Building services
Critical or life-safety electrical systems require project-specific power architecture, redundancy and protection arrangements.
Power Distribution Board for Warehouses
Warehouses and logistics facilities may require distribution for:
- Lighting
- Material handling equipment
- Conveyors
- HVAC
- Pumps
- Battery charging
- Office areas
