[Milsurplus] pp4763a problem

[Bruce Gentry]

I think there is a wiring problem or shorted power line filter in the 
power supply if it has one. A good size transformer will have a 
surprisingly low DC resisitance on the primary. Is there any chance the 
hots are mistakenly connected to the neutral, ground, or each other?  
You should not read a low resistance between the hot pins of the power 
cord when the input breaker is off.  If you remedy that and the tripping 
continues, check the 120/240 volt connections on the primary of the 
transformer.
