A three-phase board, also known as a Three Phase Distribution Board or TPN is an essential part of a three-phase electrical installation. It acts as a central hub that receives power supply from the electricity grid or a generator and then distributes it to various circuit diagrams within a building or facility.

A distribution board or distribution panel (DP) is an important part of an electricity power supply system. Its job is to split an incoming electrical power supply feed into multiple secondary or subsidiary circuit diagrams. Most of the time, each of these secondary circuit diagrams will be protected with a fuse or breaker.

The structural and technical aspects of the electrical distribution board vary, depending on the country and the electrical requirements. the typical electrical distribution board includes the following components – bus bar, fuse links, switches, bypass equipment, or residual current diagram detector (RSD).

The Way Distribution Box is made from durable material and was designed to fit in residential areas and protect electrical wiring, switches, receptacles, and support light fixtures. Features: Ideal for fire-rated walls and ceilings. Raised ground screw eliminates interference in the surface mounting applications.

A 3-phase circuit power provides greater power supply density than a one-phase circuit diagram at the same amperage, keeping wiring size and costs lower. In addition, 3-phase power makes it easier to balance loads, minimizing harmonic current flow and the need for large neutral wires.
