. . . But also be aware there are two types of devices called "Surge Protocters"
One is what I call a Spike supressor. I won't go into all of it but from time to time line surges can Spike the voltage eaily to a thousand or more. These "Clip" the spikes The spikes are very (like 1/60th or 1/120th of a second or less) long. But if you plug into say a 240 volt line with a 30 amp plug. No protection. or if the voltage drops to say 90 no protection
The Surge Guard I have .. well it will not pass power in either of those cases and some others as well.
Ditto. Folks tend to use the term "surge protector" loosely. A "true" surge protector, as you mentioned, only protects you from voltage spikes/surges a few milliseconds long (i.e., lightning strike)---that's all it does. It does nothing to protect you from constant low/high voltage situations or wiring problems. These typically cost less than $150.
Folks also use
surge protector to describe the Progressive Industries series of EMS's (Electrical Management Systems). The EMS provides standard surge protection
plus protection from constant low/high voltage situations and wiring problems. Big difference. These units typically cost $250-$400.
