I was told by another RV person that if I put the adapter on and plug this in to 50 amp I have a fear of ruining it. I usually plug in the 30s but if the 50 opportunity was the only outlet available somewhere, I wish I had bought a 50 amp

This is a great product! Works well and I now feel that my RV electrical system is protected! I would recommend this surge protector for anyone with an RV!

When first connected circuit protector showed correct wiring and ground for a few seconds. Then showed open ground after that. Park maintenance replaced 30 amp circuit breaker. Their test showed power was correct and properly grounded. I tested a 120V outlet inside my camper and it showed correct wiring and ground. Next morning this device showed circuit was correctly wired. How do I trust this device will show correct circuit analysis during each future use? I cant so returned.

Easy to use. Great value

Works just as advertised

This is a great little unit. The circuit analyzer shows you quickly if the power post is wired correctly or if theres an issue that may hurt your electrical service in your camper AND it guards against voltage spikes. Plug the unit into the post, verify that all is well, then plug your campers power cord into the surge protector. Over and done. Simple to use, great value. The cover may be a bit tight or not close entirely if your male connection is oversize. Itll still works just fine though.

So glad we had this as we had a couple of pretty strong electrical storms while we were out. No issues - so I assume that it did its job. It is reassuring to have the lights to confirm that wiring is correct before you plug your RV in.
