50 amp surge protectors

Shortly after installing my EMS I had 160V at 10:00 PM due to a open neutral. My inside remote displayed the high voltage and I could not get disconnected from the CG pedestal quick enough.

Anything that requires manual intervention means that excessive voltage existed forever. Overvoltage means response must be automatic - well less than a second. To any appliance, one second is almost forever. A protector must disconnect automatically (fast enough) due to any Hi/Lo voltage, missing safety ground, and open neutral.

These type surges typically do not exist in homes. A surge protector for homes address anomalies (surges) that are different from what typically exists in campgrounds. Compromised neutral and voltage variations are unfortunately surges common in campgrounds. A protector must automatically protect from those anomalies to be fast enough.
