Power distribution block

A power distribution block takes one large incoming conductor and distributes it to several smaller outgoing conductors on a shared conducting bar, saving space compared with stacking lugs on one terminal. It is used in control panels to distribute supply to several circuit breakers or loads.

A distinction that matters

A power distribution block is one node with many terminals; a multi-conductor terminal block is a single terminal accepting several wires.

Multi-conductor terminal block

A multi-conductor terminal provides several connection points for its documented electrical path. The schematic should show which conductors share potential and the terminal plan assigns the individual connection positions.

Drawing use: Schematic
Application: Connections & wiring
Reference family: Manufacturer

A distinction that matters

Multiple connection points and multiple isolated levels are different terminal constructions.
