Terminal strips, bus bars, please clarify

A terminal block is a strip of insulating material. On this strip are a line of terminal pairs.  Each terminal pair is electrically connected to each other, and insulated from all of the other terminals.  This gives a place where one, or several wires, can be connected to the same electrical point and be insulated from the other electrical points on the strip.  There are some terminal strips that do not have terminals in pairs. These terminals are also insulated from each other. To join these terminals, jumpers must be added between them.

A bus bar is a strip of conducting material with a number of terminals on it.  the entire bus bar and all of the terminals on it are the at same electrical point.

Both are very useful for electrical distribution and connection.  They do make wiring more simple to install and troubleshoot. The terminal strips distributes or joins many electrical signals, whereas, the bus bar distributes or joins only one electrical point.

You could use a terminal block as a bus bar. connect all the contacts on one side via a common wire. then each connection on the other side to each of your leads. the heavier the gauge the harder to manipulate, but less chance of overloading and overheating.

you could use pieces from a meccano set that are zinc plated as a bus bar and keep the wiring very neat by simply screwing one of these on the underside of your layout board and you can connect as many as you want/need I find that they are an excellent conducter.
