Even the UPS manufacturer does not claim the protection Jolly insists exists. Too make yourself feel better, you must now post insults?
Meanwhile, the average for destructive surges is about one every seven years. Destructive surges do not damage everything. Typically damaged is the appliance(s) that acts like a 'whole house' protector - earths the surge - is sacrificed to protect other appliances. Do the naive assume those other undamaged appliances were protected by 'invisible' UPSes?
Protection inside the typical UPS is a same circuit also found in power strip protectors - only less robust. Jolly Roger said UPS protection is better than that power strip. IOW better protection means smaller protectors - less joules? Just another contradiction in Jolly Roger's posts. How does Jolly resolve this? He posts insults.
Best protection also costs less money. One 'whole house' protector (properly earthed) means an effective protector for about $1 per protected appliance. Or one could buy $100 UPSes for everything. Or one could obtain the same protector circuit in a grocery store for about $10. Jolly recommends spending 10 or 100 times more money for protection that the manufacturer does not even claim to provide. Even Bud says protector circuits inside a typical UPS are inferior to those in power strips.
A protector is only as effective as its earth ground. No earth ground (ie that UPS) means no effective protection. One can either believe the majority (ie Jolly Roger who just knows) or one can first learn the science. Effective surge protection, even long before computers existed, required earthing. Those who would deny this would post insults as proof - and probably also believed Saddam had WMDs. They believe only what was told. Jolly did not notice - the UPS manufacturer does not claim protection that Jolly *knows* must exist.
