I have a 277/120V 1 PHASE 3WIRE 10 kva Isolation Transformer feeding a Isolation panel in a cath lab which is a typical brown and orange wire from a 2 pole breaker feeding the receptacles .
Question please help me understand why the polarity is shown reverse in all outlets no matter how they are terminated.I'm using a plug in type polarity tester.
I'm really trying to understand how this transformer works 120v between phases, but not to ground.
Thank for the help
