So after doing some more research this is why I think everything goes through a 30 amp junction box and 10 AWG wire. Looks like you are getting two 30 AMP circuits, no 50 AMP circuits.

Ambient conditions for rated power output with muffler and RV enclosure, per ISO 8528-1: - Temperature: 77° F (25° C)
- Altitude: 500 ft (152.4 m), (99 kPa dry)
Typical power output change based on ambient conditions:
- Temperature: Power output decreases 1% for every 10° F (5.5° C) increase
- Altitude: Power output decreases 3.5% for every 1000 ft (305 m) increase
Ratings represent minimums. Actual performance may be significantly higher based on installation and operating conditions.

Looks like it was probably just bad craftsmanship when they were connecting the wires in the junction box. Still have an issue with it melting and the possibility of a fire.
