I found a 5 KVA transformer. It looks to have never been used. The guy I got it from said it needs to be wired backward. (What ever that means) It's a GE catalog number 9T21B1004. It has two sets of 4 wires. They are marked, H1, H2, H3, & H4 all small wires. X1, X2, X3, & X4 all larger wires. It shows a winding of the Hs and Xs. On top are the Hs, they are H1 H3 H2 H4 Under that the X winding. X4 X2 X3 X1. (Primary line on H1-H4.) (Volts 240, connect H1-H3, H2-H4.) (Volts 480 connect H2-H3.) (Secondary line on X1-X4.) (120 volts X1-X3, X2-X4.) (240 volts X2-X3) (type CMS) (40 C AMB) (Class 180) I am wanting 3 phase 480 volt out, with 240 volts 3 phase (using 20 hp motor and phase converter)in. Could someone please help me with wiring this transformer up? thanks,
