I have a scenario that I am trying to figure out. I believe this is right,but want to make sure.

I am still working on our pump station at work. I have Benshaw soft starts in a control house with 110 volt "local" controls. Then approx. 500 foot away I have a 250 HP pump and a 300 HP pump. At this pump station, I have "remote" controls. These are 480 volt. (due to the distance and voltage drop for 110 volt) I have four 480 volt power relays that are to tie these two together. ( by the way, this is a 3 wire control situation )

This is where I am in a brain feeze. I have a 480 Volt circuit at this pump station. How do I utilize these relays to switch this 480 "remote" circuit back to 110 at the "local" controls.

This was all drawn up by my engineer and supposed to work, but I have no prints. I know there is a way and am sure I know how,but I don't want to screw this up.

Thanks to all!!
