I've never had a "hit" from lightening, for example, but early this year, we 
had one leg of our 240 go bad (all in-ground), and back fed to the other 120 
leg. Thus, 240 "hit" ALL of our recepticles, including the UPS. The 240 
smoked (literally) the UPS, but the 'puter and all attached to it were fine. 
It's a GOOD line of defense.
