Thanks! Let me clarify the voltage was not changed. 480 to 240 single phase. I was incorrect the secondary goes to a 3 amp circuit breaker, not 2 amp sorry. Using an amp clamp meter I am seeing about 2.3 amps. The wiring is 16 gauge stranded on the 240 side. 10 gauge 480 side with a breaker set to 7.5 amps.
