What are the types of Distribution board?

Distribution boards, also known as panelboards or breaker panels, come in several types, including main distribution boards (MDB), sub-distribution boards (SDB), and consumer units. MDBs manage electricity distribution from the main supply to various circuits, while SDBs distribute power to specific areas or loads within a building. Additionally, there are specialized boards like lighting distribution boards and motor control centers (MCC) for specific applications. Each type is designed to ensure safe and efficient management of electrical distribution.

All outlines must have main points sub points and details to be complete.?

An effective outline should clearly organize the main points that represent the core ideas of the topic. Each main point can be further broken down into sub-points that provide additional detail and support. Including specific details under each sub-point helps to clarify and elaborate on the ideas, ensuring a comprehensive understanding of the subject matter. This structured approach enhances clarity and aids in the development of a coherent argument or narrative.


What is main function of distribution bars?

Distribution bars allow a vehicle to pull more weight without damaging the rear axle or interfering with steering. They function by adding some leverage to both sides of the hitch, which allows for more even distribution of the load's weight.

What is the purpose of a sub panel with a main breaker in an electrical system?

The purpose of a sub panel with a main breaker in an electrical system is to provide a secondary distribution point for electricity in a building, allowing for additional circuits to be added without overloading the main panel. The main breaker in the sub panel serves as a disconnect switch for the circuits connected to it, providing safety and control over the flow of electricity.


What are the key differences between a sub panel and a main panel in an electrical system?

The main panel is the primary source of power distribution in a building, while a sub panel is a secondary panel that receives power from the main panel. The main panel is typically larger and has a higher amperage capacity, while a sub panel is smaller and has a lower capacity. The main panel is usually located near the utility meter, while a sub panel can be placed in a different area of the building.


What is the names of motherboards?

The other names of "motherboard" are main board, system board, planar board & logic board. Because, a mother board contains significant sub- system such as the process and other components.
