Types of Panel Boards

Panel boards are an important part of any electrical system. They provide a safe and efficient way to manage the power distribution in a building or facility. There are several different types of panel boards available, each with its own unique features and benefits.

Main Distribution Board (MDB)

The main distribution board (MDB) is the most common type of panel board. It is typically used in commercial and industrial applications to distribute power from the utility company to the various circuits within the building. The MDB contains circuit breakers, fuses, and other components that help protect against overloads and short circuits.

Sub-Distribution Board (SDB)

A sub-distribution board (SDB) is similar to an MDB but is designed for smaller applications. It is typically used in residential buildings or small businesses to distribute power from the main service panel to individual circuits. An SDB usually contains fewer components than an MDB, such as circuit breakers and fuses.

Automatic Transfer Switch (ATS)

An automatic transfer switch (ATS) is a specialized type of panel board that is used to switch between two sources of power. This allows for uninterrupted power supply in case one source fails. ATSs are commonly used in hospitals, data centers, and other critical facilities where reliable power is essential.
