Can somebody help me understand why you use a terminal block like shown below when wiring up your control box instead of just going from point A to pint B? If possible show a small sketch of it purpose.

Thanks

A terminal block is definitely beneficial when you have a one to many type connection, like power or ground distribution. They are also beneficial when a large outfit builds panels with multiple options, the terminal blocks can accommodate this variety or even help facilitate a field install. An example might be to have all the terminals, and maybe even part of the power and control wiring pre-installed for say a 4th axis or a vacuum pump, but not have all of the devices or components for a customer who doesn't need it or one who might want it later.

If your building a one and only for your own use, it is likely just an unnecessary expense.

In the case of the one shown, they have taken advantage of the ability to use jumper links, 6 pairs shown, this allows the ability to terminate multi conductors in a neat fashion.
Rather than attempt to wire them all under a common terminal.
They are also double height terminals allowing denser wire terminations.

It also extremely handy when there is field wiring that needs to be added at a later date.

I have built several gantry routers and also converted a small mill and my wiring never looks like a commercial machine control box. Maybe this is why. I have spent better part of the day trying to learn proper wiring for contactors and using these terminal blocks and any other info. I can cram into my tiny brain. I have started working on a new machine and would like it to be as neat as possible and include the proper gadgets for safety.


Thanks for the info guys.

Some also, can have a fuse or connect/disconnect link in them. Handy for fault finding without disconnecting wires.
Doesn't the professional made wiring setups, just make you sick, though.
********, should get a life.

Use wireduct, it makes everything neater.
