How can everything run on only 15amp

How can my trailer with a 50amp connection have power to everything when I am connected to a standard 15 amp 110V circuit. I would think only half the trailer would be powered! As one leg has power, the other does not.
I am used 2 adapters (20 -> 30) and (30 ->50). I didn't think the adapter is doing this.
The distribution center is the WFCO Ultra III WF-8930/50 with the WF9800 converter. Does the WFCO have the capability to sense power on only one leg and bridge the other?

You won't have power after you exceed the 15 amp draw on the breaker. I am plugged into one of my garage counter plugs. 15 amp. As soon as I draw more power like the furnace, fridge and some lights, it will pop the breaker.

It's the 30->50 adapter that ties the two legs together. Thought it only passed power on one leg. Problem solved.

Use an ohm meter and you find the 50 to 30 adapter is doing this. It is connecting both sides of the live leads together. That is why it can't be 220v.
