This information is almost six months old (back when I purchased my unit) and I see that there is a new model of the SurgeGuard so anyone in the market for a surge suppressor may want to confirm that it is (or not) still the case.
I think the information is still correct for the portable Surge Guard 34730. The manual only talks about a "Miswired Pedestal Indication". I think they would have listed accidental 220v protection (not just indication) if that was the case. I did see that the portable 50amp unit will prevent power; but not the 30amp unit.
The new model of the 34730 adds an LCD screen. Don't think there were any other changes.
