Water in the patio outlet should trip the GFCI, it should not trip or even affect the SURGE GUARD (The model Camping World sells) Water in the SURGE GUARD however will shut it down.. If you have to ask how I know that .. Well, then I can't help you :) (I know people who would have to ask and there is no hope for them.. Still we try.. But i have to stop here cause it gets political).
I figured out how to keep water OUT of my Surge Guard plug in model.
One thing I will say about it.. We have had many "power blinks" here in the park,, This is wher epower goes out for like one second,. Just long enough to kick the heck out of our Air Compressor Condensers, causing them to try to re-start with a full head of pressure (not possible) and tearing them up (Enough of those and new A/C's installed, just under a kilo-buck, and I'm haveing to replace one for DIFFERENT reasons just now, Compressor works, nothign to compress).
The Surge Guard I have shuts me down for nearly 3 minutes when this happens, the computer in the A/C holds off a bit longer when power comes back. The total is just OVER 3 minutes of Compressor Off.. Three Minutes is the recommended minimum OFF time so... It's a normal re-start, no excess head pressure... Results..
Well as I said, The compressor is still good... IT's got nothing to commpress (Unit died of other causes, not heart failure) (I nearly died of heart failure (but got it fixed) however).
