It sounds like you were using an adapter to plug your 30 amp cord into a 50 amp pedestal receptacle because you kept blowing the 30 amp breaker when using the 30 amp receptacle. If so, that allowed you to pull 50 amps through your 30 amp cord which it is not designed to handle and you could have easily melted a connection. Lesson here is to manage your electricity use better. If you are blowing the 30 amp breaker, reduce your usage by using propane for everything that you can and turn off 120V items that are not being used. Don't plug into 50 amps as your rig is not designed for it.
