A distribution board designed to divide the input main power into multiple smaller circuits is typically designed as a single-phase or three-phase distribution board. SA801F 3BDH000011R1 single-phase and three-phase are different methods of connecting external main power to buildings, each with its own advantages and disadvantages in specific situations.

The single-phase power supply is transmitted through two wires that enter the electrical service panel (fuse board). Using a single-phase power supply makes it easier to balance the power load of the entire network when multiple smaller appliances have a demand at the same time. This situation often occurs in household power circuits.

Three phase distribution boards have 3 or 4 incoming lines and are typically used in commercial and industrial environments. SA801F 3BDH000011R1 are typically associated with large, continuously used power consuming machines such as elevators, HVAC systems, and factory ovens. In dealing with higher sustained load demands, three-phase power sources are more efficient and stable than single-phase power sources.
