Hello All,

I have a light industrial client that needs 120-240 3 phase for their machinery and the supply is 120-208 3 phase.I am planning to use (3) buck-boost transformer in order to get the voltage that I need.

My question is the grounded/neutral that i need on the secondary side (240-120) is the same grounded point that is available on the 120-208 primary side. Right?

Because this is a buck and boost set up and the primary and secondary windings are electrically connected. Am i correct with this explanation?

Thank you.
Edward
