My trailer is plugged into a 30 Amp RV plug in its own subpanel that I installed outside my garage door, but it is only fed with 12 gauge Romex wiring on a 20 Amp breaker from the garage main panel. I have no problems running the A/C, the fridge, and the TV set on 120 vac, all at the same time. You should be fine with a 30 Amp circuit.


I agree, I have installed a 30 amp RV outlet in a weatherproof box just outside of our garage door.  The run from that box to the main breaker panel is about 20 ft.  I used some #12-2 w/ground to a 20 amp breaker in the box.  That installation will run everything in the Casita with no issues.

Ok, thanks everyone. Hopefully I can return the favor someday. 


Take care and safe travels.

Just because the GFCI has been dropping on occasion doesn't necessarily mean it is the problem. If the new GFCI drops out you may still have a small leak to ground somewhere in your trailer.

On the other hand the primary side of a transformer does draw a small amount of current even with no load on the secondary. That's enough to cause a small 60 cycle hum.
