Main Distribution Panels

Main Distribution Panel (MDP)

The first panel after the transformer or utility meter.

Main Distribution Board (MDB)

A distribution board fed from the main panel that splits supply to sub-boards, large loads or building blocks, with protection on each outgoing way.

Sub Distribution Board (SDB)

A board placed close to the loads it serves, so long cable runs from the main panel are avoided and each area can be isolated on its own.

Power Distribution Board (PDB)

Distributes power to equipment loads such as machines, sockets and HVAC units, with outgoing protection sized to each circuit.

Also: Power Distribution Panel

Lighting Distribution Board (LDB)

Feeds and protects lighting circuits.

Final Distribution Board (FDB)

The last board before end-use circuits, with individual protection for each outgoing circuit.

Feeder Pillar Panel

An outdoor-rated distribution enclosure that feeds multiple outgoing cables from one supply point, built for exposed locations.

Busbar Panel

A panel built around a common busbar system that links an incomer to several outgoing feeders, sized to the current the project requires.

Bus Coupler Panel

Joins or separates two busbar sections, so one section can be maintained or fed from another source without a total shutdown.

Also: LT Bus Coupler Panel

Rising Main Panel

The tap-off and distribution panels used with a vertical rising main, giving each floor its own supply point.

Medium Voltage Panel (MV Panel)

Switching and protection panels for medium voltage distribution, built to the switchgear and protection scheme specified by the project.
