Main Distribution Boards for Reliable Electrical Power Distribution

A Main Distribution Board, commonly called an MDB, is an electrical panel that receives power from the main supply source and distributes it to multiple outgoing feeders, sub-distribution boards and electrical loads. It provides a centralized arrangement for power distribution, switching, protection and isolation.

Main Distribution Boards are commonly used in factories, manufacturing facilities, commercial buildings, offices, warehouses, residential complexes, infrastructure projects and other installations requiring centralized electrical power distribution to multiple downstream circuits and panels.

An MDB generally serves as the main point of electrical distribution for an installation and supplies power to major outgoing feeders or downstream panels. A sub-distribution board is typically supplied from an MDB and distributes power further to local circuits and loads.

Depending on the application, an MDB can include incoming and outgoing circuit breakers, busbars, isolators, protection devices, meters, relays, indication equipment and other components required for electrical power distribution, protection and monitoring.

Yes. Main Distribution Boards can be configured according to incoming supply, connected load, maximum demand, number and rating of outgoing feeders, protection requirements, metering requirements, enclosure requirements and other project specifications.

Selection depends on factors such as incoming supply capacity, connected and maximum demand load, number of outgoing feeders, feeder ratings, fault level, protection requirements, metering requirements, installation environment and future expansion requirements.
