Distribution board IP ratings should match the environment: IP40 for dry indoor areas, IP55 for dusty or damp sites, and IP65 for exposed outdoor use.

A weatherproof distribution board is designed for normal outdoor conditions such as rain and dust, while a waterproof distribution board generally provides stronger water protection.

A surface mounted distribution board sits on the wall surface, while a flush mounted distribution board is recessed into the wall for a cleaner finish.

A flush mounted distribution board is an electrical board installed inside a wall cavity so its cover sits nearly level with the wall surface.

A surface mounted distribution board is an electrical board fixed directly on the wall surface to house breakers, wiring and protection devices.

SPN distribution boards are used for single phase power, while TPN distribution boards are used for three phase power and higher electrical loads.

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.
