The Difference Between Bus Bars and Terminal Blocks

Although they have similar visual appearances, Bus bars and terminal blocks serve very different purposes. The main difference between a bus bar and a terminal block is that a bus bar gathers multiple wires together for electrical distribution in a single circuit. By contrast, a terminal block has separate circuits where each incoming wire is paired with an outgoing wire.

Does it matter if a terminal block is single or double row? For example, the one at the beginning having 6 bolts instead of 12 and connecting two o rings on each other instead of separate.

At times the busbar can used instead of the block, right? As long as they handle the same amount of Amps etc.
