What are the dimensions (L, W) of the terminal block?

The dimensions are 115 mm x 49 mm. If you find the item on Amazon, there is a dimensional diagram.

Can i hook a bunch of tortoise machine?

Yes, you can. You should check the amperage drawn by each machine but I doubt you would be activating more than one or two machines at the same time. The Terminal block is ratted to 20 amps and I doubt if you would ever exceed that.

Do you have cad files available for this terminal block??

Yes, we can supply the 2D / 3D files, please google search CZH-LABS

Looking to distribute power 16vdc over 14awg wire, will this support that wire gauge?

I am using 18vdc over 16 AWG stranded wire. The 16 AWG wire easily fits into the spade connectors. I do not have any 14 AWG wire to test the connectors. I would suggest that you buy one of the terminal blocks and try your wire. If it doesn’t work just return it. I think the quality of the terminal block is great and I will be ordering more for my O scale train layout. I hope this helps you
