Is this a doorbell transformer? Or something else?

A typical doorbell transformer has two wires that are connected to a 120-volt supply. It has two screws that deliver a lower voltage, perhaps 12 or 16 or 24 volts.

Can you give us some more details of your project?

Uh.... which transformer? The one on the pole, the one running the doorbell, or the one laying beside my bed (Im serious on that one)?

Are you talking about single phase connections, 3 phase connections?

We need more info to help you!!

Hello,John Nelson
Thank you for your concern.
The transformer I talking about is the 3 phase 600 voltage to 3 phase 208 voltage one. I want to know the meaning about the terminal and how to connect the cable for it. Thank you for help.
One more thing, I heard that the neutral should be connect with the grounding in the 208v/110v, Is that right?

The type of transformer your talking about is not something a homeowner or D-I-Yer will EVER run across. I suggest you hire an electrician for this one. I'll keep the knowledge I have about this to myself and my apprentices. This is NOT something a D-I-Yer should attempt

i agree, mike...this is some serious stuff...not something the average homeowner or D.I.Y'er would ever run across...and certainly not something they should be messing with... call a licensed electrician on this one...
