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.

Guess I wasn't clear. The HW50C disconnects the downstream power to the RV withing a few milliseconds. Then with a remaining wide range of upstream voltage it displays voltage, etc but MOST important an error code. It also displays a prior error code which can be useful for knowing that there was a low voltage event while you weren't staring at the remote display for example.
