I don't have an EMS, but I think there's a very good possibility the EMS will diagnose the dogbone provided power as defective. Somebody with a 50 amp EMS can say this with more certainty. You said the EMS is happy with house current. Is this from a 240 volt outlet? If so, plug into 120 volt shore power using the dogbone and see what the EMS says.
