This does protect against over voltage when switching from shore power to Gen. power and back but does nothing for under voltage, open neutral, etc. This is not an EMS. Progressive Industries is what should be looking at for full protection.

Yes, Yes! The Progressive EMS absolutely saved our Airstream (30 amp) in a major lightning strike in Florida and Fried the EMS. Life time warranty, sent it back and was replaced within 5 days. We now have the 50 amp for the Montajmahal (3791RD). Ours is not the hard wired version though, it plugs in at the post and saved the power cord as well.
