A common question that we get asked is “I have a surge protector. Am I protected from high voltage?”
The answer is “No.” Not unless you have an automatic shutoff surge protector. The base, non-EPO Power Watchdog unit does not have auto-shutoff. If you have the Bluetooth app with alerts set up, it will alert you if you’re over the set voltage, but it can’t do anything about it. It’s up to you to unplug, turn on a generator, or go to a different pole.
The Power Watchdog with EPO unit is a little bit bigger and has the dog’s face that lights up white or red if there’s an issue. If the voltage does go too high, then the unit will turn off and the dog’s face will turn red. If the voltage drops back down to an acceptable range, then 90 seconds later, it will turn back on.
So to be protected from high voltage, you need the EPO unit, not just the surge protector.
