Campground power isn't always clean, and this Progressive Industries EMS-HW30C is built to catch the problems before they reach your RV — surges up to 1,790 joules, over/under voltage, open ground or neutral, reverse polarity, miswired pedestals, and accidental 120V, all on a 30-amp, 120V, 3,600-watt circuit.
Because it's hardwired rather than plug-in, it's meant to be installed into your RV's electrical system, where its built-in display and LED indicators give you a quick read on power conditions even in low light.
A solid layer of protection for RVers who want their electronics and appliances shielded from whatever the pedestal throws at them.
