I’m no electrician and cannot speak directly to your question, but I think that in practice it is a moot point for the following reason. You ask “what if” an overvoltage surge should occur while plugged into an outlet with faulty ground (paraphrasing here as this is how I understand your query). This should be a non-issue if you’re using a Progressive Industries EMS, as the unit tests for ground fault before ever allowing current in. If it finds a fault, it shuts out the current and alerts you with an error code. Unless you bypass the EMS. In which case it still functions as a surge protector, but you are back to your original question, for which I have no straight answer, sorry [emoji52]
