[QUOTE="westom, post: 1601763, member: 138367"] A UPS has only one function. Temporary and 'dirty' power so that when power is lost you don't lose any data. Even power strips only claim near zero protection. A valid recommendation says where hundreds of thousands of joules harmlessly dissipate. Both technologies (lightning rods and 'whole house' protection) have been proven by over 100 years of science and experience. Why would a thousand joules protector somehow absorb a surge that is hundreds of thousands of joules? Why would a 2 cm part inside an adjacent protector (power strip or UPS) stop what three miles of sky could not? A power strip can, in some cases, compromise protection already inside electronics. In rare cases, caused house fires. Why spend so much money on something (power strip or UPS) that only claims near zero protection? Because so many, educated by hearsay and advertising, recommended it? Useful recommendations provide hard numbers. Your concern is of transients that (ie lightning) may be 20,000 amps. So a minimal 'whole house' solution is 50,000 amps. And costs you about $1 per protected appliance. Hardware protection was repeatedly defined. Why keep looking for protection using items with near zero numbers and 2 cm protector parts? Lightning is discussed only because it is typical of all other destructive surges. Other equivalent surges occur without any warning. Even unplugging is a least reliable solution. UPS is temporary and 'dirty' power for data protection. A reliable solution for tens or 100 times less money was defined repeatedly. Simple concepts. Where do hundreds of thousands of joules harmlessly dissipate? A protector is only as effective as its earth ground - which a UPS does not have. [/QUOTE]
