	Subject - World wide specs list for 3 phase power. BobG I have found several comprehensive specification lists for single phase power use world wide, but can't find the same for three phase power. Doe's someone know of an online site with this information? Appreciate any help on this. Bobg lctrc789 Bob, I don't know of a site like that, perhaps Magnatek, G.E. or Westinghouse maybe. Three phase power is more commercial and industrial and utility sided for larger applications. Single phase of course is more common because of the large amount of residential applications. I would be interested in any site that you have found for single phase and I will look for some three phase sites. I could email you some info on three Phase delta and wye through our company if you need it. It does show three phase delte to wye and corner grounded delta and open delta configurations. The utility company here uses a lot of two transformer hookups to get three pahse power.
