This is a hardwired total electrical protection system so you are not only protected from surges but also high and low voltage, which is more of what you will encounter in RV parks. It comes in 30A and 50A. If you don’t want to hard-wire it into your RV, you’ll want the Portable Model.
You might want to also consider the remote display unit.
If you have a 30A RV, check out the other options at TechnoRV here..
