Thanks for "fessin-up" to that! RVing would be SO much better if everybody understood that arcing thing and connected/disconnected accordingly.
I don't have the engineering to back it up, but just looking at 30A and 50A plugs, it seems to me that 30A connections are more failure prone than the 50's. I also think more 30A RV's run close to max amps than the 50's do. All this means the 30A receptacles we plug into are likely to be shot! Pitted from arcing, leading to heating, leading to lost tension on the contacts. Leading to more of the same.
Met an RVer who's an electrician. He keeps a couple 30A male plugs aboard, and has installed several for fellow campers. Shout Out to You, PHIL!
