What are the different types of electrical panel boards?

Electrical panel boards referred to as distribution boards or breaker boxes are crucial parts of the electrical systems that regulate and distribute electricity inside a structure or facility. They occur in a variety of forms, each created for a particular function. It’s crucial to remember that electrical panels can be categorized in a variety of ways including technologies, applications, capacity, performance, and even safety. We shall discuss the 15 types of electrical panel boards and examine various electrical panel board kinds, their purposes, and typical uses in this post.

The Types of Electrical Panels

Here we will learn about 15 different types of electrical panels. Some of the points we have discussed below which you should keep into consideration before buying electrical panels for your locations. 

1. Main Distribution Board (MDB)

The main hub for distributing electrical power inside a building is the Main Distribution Board, sometimes known as the main panel or load center. It draws power from a generator or the utility grid and distributes it to different branch circuits all across the building. To safeguard these circuits from overloads, the MDB normally houses circuit breakers or fuses.

2. Sub-Main Distribution Board (SMDB)

Sub-Main Distribution Boards are used to distribute power from the main distribution board to different sections or floors of a building. They help reduce cable lengths and provide a localized point for controlling circuits within specific areas.

3. Final Distribution Board (FDB)

Near the finished appliances or equipment are where you’ll find the final distribution boards. Before the energy reaches outlets, switches, and lighting fixtures they act as the final distribution point. FDBs are frequently installed close to the loads they support.

4. Lighting Distribution Board (LDB)

Lighting Distribution Boards are used to distribute power to lighting circuits, as their name suggests. It is simpler to regulate and maintain lighting systems since they come with circuit breakers or fuses made for lighting loads.

5. Power Distribution Board (PDB)

Power distribution boards are in charge of supplying electricity to non-lighting loads like outlets, equipment, and appliances. To ensure safety and effective power distribution they contain circuit breakers or fuses designed to handle higher current levels.

6. Motor Control Center (MCC)

Specialized panel boards known as motor control centers are used to manage and safeguard electric motors. They include variable frequency drives (VFDs), motor starters, and related control elements. To control motors used in machinery and processes, MCCs are frequently employed in industrial settings.

7. Generator Control Panel (GCP)

When backup power is required, generator control panels are crucial. During blackouts, they have control over the transition of power from the utility system to a backup generator. GCPs guarantee a smooth switch and power distribution as required.

8. Capacitor Bank Panel (CBP)

Battery Bank In order to increase power factor and decrease reactive power in electrical systems, panels are employed. To increase energy efficiency they have capacitors that can be turned on or off to account for inductive loads.

9. Feeder Pillar

Street lighting, traffic signals, and other outdoor applications’ electrical equipment is housed in feeder pillars, which are exterior enclosures. They offer security and convenient access for maintenance staff.

10. Control Panel

Custom-made boards called control panels are used to monitor and control a variety of equipment and operations. They are used in a variety of applications including HVAC systems and industrial automation.

11. Distribution Board for Renewable Energy Sources

As the use of solar panels and wind turbines grows, specialized distribution boards are utilized to integrate renewable energy sources into the electrical grid. Between the batteries the main distribution network, and the renewable energy source, these boards regulate the flow of electricity.

12. Data Center Power Distribution Board

In order to offer redundancy, high availability, and precise management of power distribution to servers and networking equipment, data centers use power distribution boards.

13. Emergency Power Off (EPO) Panel

In dangerous settings like hospitals and laboratories, EPO Panels are safety equipment. They offer a way to swiftly shut electricity in an emergency to avoid dangers.

14. Marine Distribution Panel

Marine distribution panels are used in maritime and offshore situations to manage electrical power distribution aboard ships, oil rigs and similar structures. They are built to withstand challenging conditions and guarantee maritime security.

15. Explosion-Proof Panel

In dangerous locations where combustible gases or dust may be present, explosion-proof panels are employed. They’re made to stop electrical sparks that can cause explosions.


In conclusion, there are many different types and uses for electrical panel boards. They are essential in making sure that energy is distributed safely and effectively in a variety of locations from homes to businesses. For good electrical system design and maintenance knowledge of the many panel board types is crucial since it makes it possible to choose the appropriate panel for each individual application.
