Main Distribution board (MDB)

What is GRSh?

Main distribution boards are most often located in the power supply system of a building (structure) at the upper level of power distribution with a voltage of 0.4 kV.

The main switchboard is usually a prefabricated structure consisting of functional elements (panels), namely:

• -introductory panel
• -sectional panel
• -distribution panel

Power supply to distribution panels is provided via a main busbar; the characteristics of the devices and the main busbar installed in the main switchboard are selected based on the consumed power or the power of the power source.
