I have a machine that only has 3-phase 220Vac (and plant's 3-phase 480Vac). There are 2 heating elements. Element1 is powered by Phase1 and Phase2 (220Vac phase to phase). Element2 is powered by Phase2 and Phase3. Each element draws 22 amps when powered (using PID temperature control). The fact that elements are floating causes a lot of maintenance problems, so I'm wondering if it would make sense to rewire it so that Element1 is powered by Phase1 to Ground (127Vac, 12.7A), Element2 powered by Phase2 to Ground. (I believe target temperature is low enough that it can still be achieved despite power downgrade.) Note that the machine also has four 220Vac 3-phase ac motors, among other things. Question is: will this design change create massive problems? (Probably yes.) What problems will I see? Should I just buy a 380 25A transformer, so I can get two 220 phase to ground?
