Industry Knowledge

A TPN distribution board is a three phase and neutral board that receives three phase power and distributes it to protected electrical circuits.

An SPN distribution board is a single phase and neutral board that receives one-phase power and divides it into protected branch circuits.

A single phase distribution board is used for lighter loads, while a three phase distribution board is used for heavier commercial or industrial power demands.

A three phase distribution board receives three phase power and divides it into protected circuits for heavy loads, machinery and larger electrical systems.

A single phase distribution board receives single phase power and divides it into protected circuits for lighting, sockets and small electrical loads.

To choose the right distribution board, match the power supply, circuit quantity, load capacity, protection devices, and installation environment.

Distribution boards need covers, doors and locks to prevent accidental contact, protect internal parts, reduce tampering, and keep electrical access safer.

DIN rail terminal blocks are insulated connectors mounted on a DIN rail to join, organize, and distribute wires inside a distribution board.

The neutral bar carries normal return current in a distribution board, while the earth bar carries fault current safely to reduce electric shock and equipment risks.

A busbar in a distribution board is a solid metal conductor that carries incoming power and distributes it to circuit breakers or other electrical connection points.

The main components of a distribution board are the main switch, circuit breakers, busbars, RCDs, neutral and earth bars, DIN rail, and enclosure.

Distribution boards, also called DB boards or electrical panels, can be classified by function, power supply phase, installation method, application environment, and special use.
