This is the very 1st thing I bought. I installed it myself almost 1 full year before getting a RV
We got 5 configurations to park the RV at home, we call this view the Sunstar Patio. I use the 20 amp all the time. i.e air compressor etc. we have 50 amp coach, but I alternate. We have yet to ever trip a breaker doing what we do when on 30 amp service. We spent the entire Memorial day weekend in Arkansas on 20 amp service. However, I only ran 1 AC.
My brother can park his 30amp Splinter next to it and we can both be connected
Note: 60amp GE Breaker in Main Electrical Panel
