need help with a pdu unit installation
Just to clear up one thing: most houses actually run as Split-phase which is single-phase, and a center-tap neutral. Two-phase power is a separate thing and basically obsolete.



Unfortunately, you can't connect a 3-phase device to single-phase power directly. I am not sure precisely what would happen, but I strongly suspect it would release the magic blue smoke (hint: this is bad).

You can get phase converters, these cost from a couple thousand to multiple thousands of dollars. 

 

You'd be better off buying a single-phase PDU. Easier install, cheaper, and don't have a huge phase converter taking up a bunch of space.
