Whomever wired his EMS did it bass-ackwards. Anything reconnectable on the incoming shore power from plug to his breaker panel is reconnectable. But it is commonly it's in the umbilical cord.
Or maybe the 30 receptacle in the garage is wired wrong and it always had a problem but was never checked.
This is what I'd check first. Getting the Hot and Neutral swapped when wiring the plug is very easy to do. In the old days before the 3rd wire ground was introduced it usually didn't matter how you wired the plugs. But with the 3rd wire ground and with a lot of the newer electronics it does matter and can make a difference (it actually makes a difference on 2-wire connections too which is why most plugs can only plug in one way with the larger blade on one side of the plug). I always use a tester on any new circuit or plug I install just to make sure I did it right.
