A metal knockout box hole size should be selected according to the conduit connector, cable gland or cable clamp that passes through the box—not simply according to the cable diameter. Conduit nominal size, fitting thread, required mounting hole and actual knockout diameter are related measurements, but they are not necessarily

A metal knockout box may also be described as a metal back box, junction box, switch box, socket box, outlet box or device box. However, these terms are not always exact synonyms. Each name may emphasize a different aspect of the box, such as its cable-entry structure, electrical function, mounting

Lightning is one of the most powerful natural phenomena. A direct lightning strike can damage buildings, electrical systems, and equipment. A lightning rod provides a safe path for lightning current to discharge into the ground, reducing the risk of fire, structural damage, and electrical failures.

A Transparent Cover Knife Switch is a manual electrical isolation switch designed to safely disconnect power circuits and provide a clear view of the switch status.

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.
