Switchgear: Basics and Importance of the Main Distribution Board (MDB)
Practically everyone encounters switchgear in their life, as electricity is an integral part of our everyday existence. Switchboards play a key role in the distribution of electrical energy. What is a main distribution board (MDB)? It is a low-voltage complete device that provides the entry of electricity into a building, its distribution among the main consumers, and protection against short circuits and overloads.
Types of MDBs by Purpose
Main distribution boards can be classified into several types based on their purpose:
- sectional;
- linear;
- incoming.
MDBs can have from one to three inputs. If the board has one input, it includes one incoming and linear panel. In the case of two or three inputs, additional input, linear, and sectional panels are implemented. The final appearance of the MDB can be floor-mounted, wall-mounted, or built-in, depending on design solutions.
Applications of Main Distribution Boards
The range of applications for main distribution boards is quite broad. They are used in the following areas:
- equipment for incoming devices;
- transformer substations;
- industrial facilities;
- boiler rooms;
- medical institutions;
- administrative and residential buildings;
- other high-power consumers.
Main Functions of MDBs
The use of electricity has become so widespread that any disconnection can significantly complicate life. The main distribution board plays an important role in the safety and uninterrupted supply of electrical energy, preventing various unpleasant situations. The main problems that can arise in the absence of an MDB include:
- insufficient electricity input;
- uncontrolled distribution of electricity;
- insufficient protection against voltage spikes.
The principle of operation of the MDB is simple: in case of a power supply failure or changes in parameters that may threaten the operation of the equipment, the board automatically disconnects the power supply or a certain part of it. When a current leak occurs, a residual current device (RCD) is triggered. Additional equipment, such as lightning rods, enhances fire safety.
Advantages of Custom Assembly of MDBs
Custom assembly of MDBs allows the design to consider the specifics of operation, functionality, and application parameters. Even under non-standard usage conditions, it is possible to create an MDB that is convenient and practical, as the assembly takes into account the area and geometry of the space.
