I apologize if I posted this under the wrong section. I have a GE 5 KVA 480 or 240 to 120 240 single phase transformer. Model number 9T21B1004G02 . My issue is when energized on 480 I have 240 from phase to phase. 130 from X1 to ground, but only 50 volts X4 to ground. I have tried a 2nd transformer, exact same result. Hooked it to a different power source, same result. All the obvious has been checked. Proper input voltage and that. I have hooked it up bonded and un bonded, ground to water line, ground to ground grid. Nothing is changing. Im still questioning if this transformer can be used to feed a small 120/240 volt panel and get both voltages. According to GE it is. I have been on the phone with GE and we have went over everything step by step. Any help would be appreciated with this model.
