Does a thre phase transformer need a center point, or three prong ac/dc outlet?

I am trying to determine what is needed for the tranformer to work properly.

A 3 phase transformer needs 3 phase power. This is generally a 4 prong plug and will be 220 volts or higher. It will not work in a normal outlet.

Yes, if the transformer has a center ground (3 prong plug)-IT MUST BE CONNECTED. If one fails to do so there is a great risk of electrocution or fire.
